  • STUDY OF INFECTIOUS TRIGGERS THAT UNDERLIE SO-CALLED AUTOIMMUNE DISEASES

    There is a large class of chronic diseases called Autoimmune Diseases by modern medical community. Autoimmune diseases are defined as diseases that arise when the immune system mistakenly attacks the body’s own tissues. The pathophysiology of these so-called autoimmune diseases is multifaceted, involving genetic predispositions, environmental factors, and immune system dysregulation. Recent researches have implicated infectious diseases as potential triggers for many conditions that were considered to be due to autoimmunity, either through molecular mimicry, bystander activation, or direct tissue damage. Concept of ‘autoimmune diseases’ is currently undergoing a redefining process.

    Antibodies are crucial components of the immune system, playing a pivotal role in defending the body against infectious diseases. They identify and neutralize pathogens such as bacteria, viruses, and toxins. However, under certain conditions, antibodies can also contribute to the development of diseases by their off-target actions. Pathogens may possess antigens that closely resemble the body’s own tissues. When the immune system produces antibodies against these pathogens, those antibodies may mistakenly target and attack the body’s own cells, leading to pathology which are wrongly called ‘autoimmune diseases’. During an immune response, the initial target of antibodies can broaden to include additional epitopes (parts of antigens). This can lead to an immune attack on the body’s own tissues. Infections can cause inflammation and the release of molecules that mimic the antigens of pathogens. These biological molecules mimicking as pathogenic antigens can then be targeted by the antibodies, leading to what is wrongly considered autoimmune diseases.

    Infections or tissue damage can expose hidden self-antigens to the immune system. Once exposed, these antigens can be recognized as foreign, leading to an immune response from the antibodies. Some bacteria and viruses produce superantigens, which can non-specifically activate a large number of T-cells. This widespread activation can lead to what is called autoimmune response. Individuals with certain genetic backgrounds are more prone to developing so-called autoimmune diseases. The interaction between antibodies and infectious diseases is complex and can lead to chronic diseases through mechanisms like molecular mimicry, epitope spreading, bystander activation, cryptic antigen exposure, and superantigens. Understanding these mechanisms is crucial for developing preventive and therapeutic strategies for autoimmune diseases.

    As per MIT explanation of homeopathy, concept of ‘miasms’ originally described by Dr Samuel Hahnemann in his works as causative factors of chronic diseases, are scientifically redefined as chronic disease dispositions caused by off-target actions of anti-bodies generated in the body against ‘alien proteins’ such as viral, fungal or bacterial infectious agents, parasites, vaccines, environmental allergens, venoms, deformed proteins etc. Once understood scientifically from this perspective, we need not limit the number of miasms to three only as hahnemann explained. Any infectious disease that can generate antibodies in the organism can work as a causative factor of chronic miasms by their off-target actions. Vaccinations, which induce production of anti-bodies in the organism, also have to be considered as causative factors of miasms. Moreover, history of allergic reactions towards any ‘alien proteins’ entering the organism, such as various allergens, bites and stings of insects and serpents, and anaphylactic reactions also have to be considered as causative factors of ‘miasms’.

    It was Samuel Hahnemann, who for the first time in history of medical science observed that diverse types of chronic diseases could be produced by the ‘residual effects’ of infectious diseases, and he called this chronic disease dispositions as ‘miasms’. I have been trying to explain this phenomenon in scientific terms, and to find out how chronic diseases could be produced by infectious agents, even after the infections are over, which led me into the realization that infectious agents can produce life-long chronic disease dispositions only through off-target actions of antibodies generated in the body against them.

    By introducing the concept of miasms, Hahnemann was actually trying to explain the role of residual effects of acute infectious diseases in causing chronic disease dispositions. His main focus was on miasm of what he called psora arising from infectious itch and leprosy, miasm of syphilis, as well as miasm of sycosis arising from HPV- gonorrhoea complex, which were most widespread infectious diseases around his place during his time.

    Recent researches have started to provide enough data to show that it is not the antibodies generated against native cells that cause autoimmune diseases, but it is the antibodies generated in the body against infectious agents and ‘alien proteins’ that cause those diseases. This new understanding is bringing a great paradigm shift in the diagnosis and treatment of so-called autoimmune diseases. It also underscores the correctness of miasm concept of chronic diseases in homeopathy, which was so far considered unscientific by modern scientific community. Now it is obvious that what Hahnemann called ‘miasmatic diseases’, and what modern medicine calls ‘autoimmune diseases’ belong to the same class.

    Look into the exhaustive list of diseases included in the class of autoimmune diseases which are actually ‘chronic diseases caused by off-target actions of antibodies. Kindly go through the complete list of autoimmune diseases given below, and the modern understanding of their relationships with infectious diseases, to realise the real magnitude of ‘anti-body mediated’ diseases or ‘miasmatic’ diseases we encounter in our day today clinical practice.

    Even though Hahnemann could rightly observe the role of miasms or residual effects of infectious diseases in the causation as well as the curative process of chronic diseases, he could not explain the exact biological mechanism by which this phenomenon works. This failure was due to the primitive state scientific knowledge available during his period, which later led to various kinds unscientific and “dynamic” interpretations by his “disciples” and “followers” which continue till the present day. Using the scientific knowledge already available now, I have been trying to explore the exact molecular mechanism by which residual effects of acute infectious diseases contribute to the development of chronic disease conditions, which Hahnemann called ‘miasms’.

    See, how Hahnemann’s concept of chronic diseases relating it with infectious diseases, paves the way for a scientific understanding of a whole class of grave diseases, and developing of a whole new range of therapeutic agents and techniques to combat them. Hahnemann’s observations of chronic diseases, relating it with infectious diseases, would have been a revolutionary event in medical history, had anybody- be it hahnemann himself, his followers or scientists- taken up the task of explaining it in scientific terms. Had anybody asked the question how an infectious disease can cause life-long residual effects in the organism even after the infection is over, everything would have been clear. It would have been obvious that infectious agents can produce life-long residual effects in the form of chronic diseases only through ANTIBODIES generated in the body against infectious agents. Such a realisation would have helped medical as well as scientific community to view antibodies from a different perspective- as causative agents of diverse types of chronic diseases- over and above their role as defence molecules.

    Infectious diseases and their role in so-called autoimmune diseases necessitate long-term monitoring of patients to identify and manage such immune responses early. This includes regular screenings and proactive management of infections known to trigger autoimmunity.Immune responses can sometimes target cancer cells, leading to paraneoplastic syndromes. Understanding the dual role of the immune system in cancer and so-called autoimmunity can help in developing immunotherapies that minimize autoimmune side effects while effectively targeting cancer cells. Identifying biomarkers that predict the development of autoimmune diseases following infections can help in early diagnosis and intervention. Biomarkers can include specific antibodies, cytokine profiles, and genetic markers.

    Tailoring treatments based on an individual’s genetic makeup, infection history, and immune profile can improve outcomes and reduce adverse effects. Precision medicine approaches can help in developing targeted therapies that address the underlying causes of autoimmunity.

  • MIT HOMEOPATHY STUDY OF PATHOPHYSIOLOGY OF PRIMARY AMOEBIC MENINGOENCEPHALITIS (PAM) CAUSED BY NAEGLERIA FOWLERI

    MIT homeopathy approach to Primary Amoebic Meningoencephalitis (PAM) involves the study of molecular mechanism involved in the pathophysiology of the disease, and identifying the molecular targets, ligands and functional groups that are relevant in its therapeutics. Such a study is expected to pave the way for further research in developing a new range of highly effective, safe, and target-specific molecular imprinted drugs that could be used in prevention and treatment of this dreaded disease.

    Primary Amoebic Meningoencephalitis (PAM) is a rare but highly fatal central nervous system (CNS) infection caused by Naegleria fowleri. Commonly referred to as the “brain-eating amoeba,” N. fowleri primarily affects healthy individuals, often children and young adults, following exposure to contaminated water sources. Naegleria fowleri is a thermophilic, free-living amoeba found in warm freshwater environments such as lakes, rivers, hot springs, and inadequately chlorinated swimming pools. It exists in three forms: Cyst is a dormant, resistant form that can survive in adverse conditions. Trophozoite is the active, feeding, and reproducing form responsible for infection. Flagellate is a temporary form used for motility when the amoeba is in nutrient-depleted environments.

    The lifecycle of N. fowleri involves the transition between cyst, trophozoite, and flagellate stages, depending on environmental conditions. The trophozoite form is the infective stage, entering the human body through the nasal passages during activities involving exposure to contaminated water. PAM begins when N. fowleri trophozoites enter the nasal cavity, typically during swimming or diving in warm freshwater. The amoeba adheres to the nasal mucosa and migrates along the olfactory nerves through the cribriform plate to the olfactory bulbs in the brain. N. fowleri attaches to the nasal mucosa via amoebostomes (food cups) and surface proteins such as integrins and fibronectin-binding proteins. The amoeba produces cytolytic enzymes, including phospholipases, neuraminidase, and proteases, which facilitate tissue invasion. Guided by chemotactic responses, the amoeba migrates along the olfactory nerve into the CNS.

    Once in the CNS, N. fowleri proliferates rapidly. The pathophysiological mechanisms contributing to CNS damage include the release of cytolytic molecules such as phospholipases, proteases, neuraminidase etc, causing direct damage to neuronal and glial cells. Proteolytic enzymes and inflammatory mediators disrupt the blood brain barrier, allowing more trophozoites and immune cells to enter the brain parenchyma. Proinflammatory cytokines (TNF-α, IL-1β) and immune cells (neutrophils, macrophages) infiltrate the CNS, leading to inflammation and edema.

    The clinical course of PAM progresses rapidly, typically within 5-7 days post-exposure. Early symptoms resemble bacterial meningitis and include severe frontal headache, fever, nausea, vomiting, altered mental status (confusion, hallucinations), neck stiffness, photophobia etc. As the disease progresses, patients may develop seizures, coma and cranial nerve palsies

    Early and accurate diagnosis is critical but challenging due to the rarity of PAM and its nonspecific symptoms. Diagnostic methods include Cerebrospinal Fluid (CSF) Analysis, Polymerase Chain Reaction (PCR) and Imaging Studies.

    PAM has a high mortality rate, but early aggressive treatment can improve outcomes. Treatment strategies include antimicrobial therapy, and supportive care for management of increased intracranial pressure, seizures, and other complications.

    Naegleria fowleri initiates infection by attaching to the nasal mucosa. This initial attachment is critical for the amoeba’s subsequent migration into the central nervous system (CNS). The process involves specialized structures and surface proteins, including amoebostomes, integrins, and fibronectin-binding proteins.

    Amoebostomes, also known as food cups, are specialized structures that play a crucial role in the attachment and phagocytosis processes of N. fowleri. Amoebostomes facilitate the attachment of N. fowleri to the epithelial cells of the nasal mucosa. The amoebostomes act like suction cups, creating a strong adherence to the cell surface. Once attached, amoebostomes can engulf small particles and cell debris from the nasal mucosa, aiding in nutrient acquisition and possibly contributing to localized tissue damage that facilitates further invasion.

    Amoebostomes have a complex molecular composition that allows them to effectively interact with host cells and the extracellular matrix. Amoebostomes are dynamic, cup-shaped invaginations on the surface of the trophozoite form of N. fowleri. They are involved in capturing and engulfing particles, including host cells and debris. The molecular structure of amoebostomes is characterized by several key components.

    The structural integrity and dynamic nature of amoebostomes are maintained by the cytoskeleton. Actin Filaments provide structural support and are involved in the formation and extension of the amoebostome. Actin polymerization and depolymerization drive the movement and shape changes necessary for the phagocytic activity of amoebostomes. Myosin motor proteins interact with actin filaments to facilitate the contraction and expansion of the amoebostome, enabling the engulfment of particles.

    Amoebostomes are equipped with various surface adhesion molecules that mediate attachment to host tissues. Lectins are carbohydrate-binding proteins that recognize and bind to specific sugar moieties on the surfaces of host cells, facilitating initial adhesion. Integrin-Like Proteins function similarly to integrins in higher eukaryotes, mediating attachment to extracellular matrix components and providing stability during phagocytosis. Fibronectin-Binding Proteins specifically bind to fibronectin in the extracellular matrix, enhancing the amoeba’s adherence to host tissues. Amoebostomes contain several enzymes that aid in breaking down host tissues and facilitating nutrient acquisition. Phospholipases are enzymes that degrade phospholipids in host cell membranes, aiding in the penetration and disruption of host cells. Proteases such as cysteine proteases and serine proteases degrade host proteins, enabling the amoeba to digest and absorb nutrients from host cells and tissues. Neuraminidase is an enzyme that cleaves sialic acid residues from glycoproteins and glycolipids on host cell surfaces, enhancing attachment and possibly aiding in immune evasion.

    The molecular components of amoebostomes work in concert to facilitate their primary functions. Surface adhesion molecules, such as lectins and fibronectin-binding proteins, mediate initial binding to host cells and extracellular matrix components. Cytoskeletal elements like actin and myosin enable the amoebostome to extend and retract, capturing and engulfing particles through phagocytosis. Enzymatic components break down captured particles, allowing the amoeba to absorb nutrients and further invade host tissues.

    N. fowleri utilizes a range of surface proteins to mediate its attachment to the nasal mucosa. Key among these proteins are integrins and fibronectin-binding proteins, which play distinct yet complementary roles in the attachment process.

    Lectins and fibronectin-binding proteins are essential surface molecules that mediate the attachment of Naegleria fowleri to host tissues. These proteins facilitate the initial stages of infection by allowing the amoeba to adhere to the nasal mucosa and interact with the extracellular matrix (ECM). Below, we explore the molecular characteristics and roles of lectins and fibronectin-binding proteins in N. fowleri. Lectins are carbohydrate-binding proteins that recognize and bind to specific sugar moieties on the surfaces of host cells. In N. fowleri, lectins play a crucial role in the attachment and colonization of the host tissue. Lectins have high specificity for certain carbohydrate structures, such as mannose, galactose, and sialic acid residues. This specificity allows N. fowleri to target and bind to glycoproteins and glycolipids on the host cell surface. Lectins typically consist of one or more carbohydrate-recognition domains (CRDs) that mediate binding to sugars. These domains determine the lectin’s affinity for specific carbohydrate structures. Lectins facilitate the initial contact between N. fowleri and the host epithelial cells in the nasal mucosa by binding to carbohydrate residues on the cell surface. This attachment is the first step in the invasion process. Binding of lectins to host cell carbohydrates can trigger signaling pathways that may alter host cell behavior, potentially aiding in the amoeba’s invasion and evasion of immune responses. Lectin-carbohydrate interactions can modulate the host immune response, potentially helping the amoeba avoid detection and destruction by the host immune system.

    Integrins are transmembrane receptors that facilitate cell-extracellular matrix (ECM) adhesion. N. fowleri expresses integrin-like proteins that enhance its ability to bind to host cells. Integrin-like proteins on N. fowleri recognize and bind to specific ligands in the ECM and on the surface of nasal epithelial cells, promoting firm attachment. Upon binding, integrins can activate intracellular signaling pathways that enhance the amoeba’s motility, invasiveness, and survival in the host environment. Integrins interact with the cytoskeleton, providing mechanical stability to the attachment and facilitating the amoeba’s movement across and into the nasal mucosa.

    Fibronectin-binding proteins are another critical component of N. fowleri’s attachment arsenal. Fibronectin is a high-molecular-weight glycoprotein of the ECM that plays a vital role in cell adhesion, growth, and differentiation. N. fowleri’s fibronectin-binding proteins specifically recognize and bind to fibronectin molecules present in the nasal mucosa. The binding of fibronectin-binding proteins to fibronectin strengthens the adhesion of N. fowleri to the host tissue, facilitating a stable attachment that supports further invasion. Interaction with fibronectin can modulate host cell signaling pathways, potentially altering host cell behavior in ways that favor amoeba survival and dissemination.

    Fibronectin-binding proteins are specialized surface proteins that specifically interact with fibronectin, a high-molecular-weight glycoprotein present in the extracellular matrix. Fibronectin-binding proteins contain specific domains that recognize and bind to fibronectin. These domains are often structurally similar to those found in fibronectin receptors of higher eukaryotes. The fibronectin-binding domains of these proteins are adapted to tightly bind fibronectin, facilitating strong adhesion to the ECM. By binding to fibronectin, these proteins may help the amoeba to anchor itself while secreting enzymes that degrade ECM components, facilitating deeper tissue invasion. Interaction with fibronectin can disrupt normal cell signaling pathways in the host, potentially weakening cell junctions and increasing tissue permeability, which aids in the amoeba’s spread.

    The combined action of amoebostomes, integrins, and fibronectin-binding proteins ensures a robust attachment of N. fowleri to the nasal mucosa, setting the stage for subsequent invasion into the CNS. Amoebostomes provide initial mechanical adhesion, while integrins and fibronectin-binding proteins ensure a strong and specific attachment to the ECM and host cell surfaces. These adhesion mechanisms also trigger host cell responses that may inadvertently aid in the amoeba’s invasion and evasion of the immune system. Secure attachment allows the amoeba to anchor itself firmly as it begins to migrate along the olfactory nerves through the cribriform plate into the brain.

    The combined action of lectins and fibronectin-binding proteins ensures effective attachment and colonization of N. fowleri in the nasal mucosa. Here’s how they work together in the context of pathogenesis. Lectins mediate the initial attachment to host cells by binding to surface carbohydrates. Once attached, fibronectin-binding proteins reinforce this attachment by binding to fibronectin in the ECM, ensuring a stable and firm adhesion. The binding of lectins and fibronectin-binding proteins may create a synergistic effect that enhances the amoeba’s ability to withstand mechanical forces and immune defenses. These proteins not only help the amoeba adhere to the host tissue but also prepare the local environment for invasion by altering cell signaling and degrading ECM components, creating pathways for the amoeba to penetrate deeper into the tissue. Lectins and fibronectin-binding proteins are critical to the pathogenicity of Naegleria fowleri, facilitating its attachment to and invasion of host tissues. By understanding the molecular structure and functions of these proteins, researchers can develop targeted strategies to block these interactions, potentially preventing the establishment and progression of Primary Amoebic Meningoencephalitis.

    The pathogenicity of Naegleria fowleri trophozoites is largely mediated by their ability to release cytolytic molecules that cause direct damage to neuronal and glial cells in the central nervous system (CNS). These molecules include phospholipases, proteases, and neuraminidase, each contributing to the amoeba’s destructive effects on brain tissue. Understanding the specific mechanisms by which N. fowleri trophozoites release and utilize cytolytic molecules provides critical insights into the pathophysiology of Primary Amoebic Meningoencephalitis. This knowledge is essential for developing targeted therapeutic strategies aimed at mitigating the amoeba’s cytotoxic effects and improving clinical outcomes for affected patients.

    Phospholipases are enzymes that hydrolyze phospholipids, which are critical components of cell membranes. The release of phospholipases by N. fowleri trophozoites leads to the breakdown of phospholipids. Phospholipase activity compromises the integrity of neuronal and glial cell membranes, leading to cell lysis and death. The breakdown of membrane phospholipids releases arachidonic acid, a precursor for pro-inflammatory eicosanoids. This promotes inflammation and further tissue damage. Disruption of membrane phospholipids can affect cell signaling pathways, impairing cell function and contributing to cytotoxicity.

    Proteases are enzymes that degrade proteins by hydrolyzing peptide bonds. N. fowleri produces several types of proteases, including cysteine proteases and serine proteases, which facilitate its pathogenicity through various mechanisms. Proteases degrade components of the extracellular matrix (ECM), such as collagen and laminin, aiding the amoeba in penetrating and migrating through brain tissues. Proteases can directly degrade structural proteins of neuronal and glial cells, leading to cell rupture and necrosis. By degrading host proteins, proteases can interfere with the host immune response, helping the amoeba evade detection and destruction by immune cells.

    Neuraminidase is an enzyme that cleaves sialic acids from glycoproteins and glycolipids on the surface of cells. The action of neuraminidase contributes to N. fowleri pathogenicity in several ways. By removing sialic acid residues, neuraminidase alters cell surface properties, facilitating the amoeba’s adhesion to neuronal and glial cells. Cleavage of sialic acids can mask the amoeba from immune recognition, thereby modulating the host immune response and aiding in immune evasion. Neuraminidase activity can expose underlying cell surface molecules, making them more susceptible to further degradation by proteases and other enzymes.

    The combined action of phospholipases, proteases, and neuraminidase results in extensive neuronal and glial cell damage, The destruction of cell membranes and structural proteins leads to cell death by necrosis, a process associated with inflammation and further tissue damage. The release of cellular debris and pro-inflammatory mediators from damaged cells triggers a robust inflammatory response, contributing to brain edema and increased intracranial pressure. The enzymatic degradation of ECM and endothelial cells compromises the integrity of the blood-brain barrier (BBB), facilitating further invasion of the CNS by N. fowleri and immune cells, exacerbating inflammation and damage.

    Primary Amoebic Meningoencephalitis caused by Naegleria fowleri is a devastating disease with a rapid progression and high mortality rate. Understanding the pathophysiology of PAM is essential for early diagnosis and prompt treatment, which are critical for improving patient outcomes. Continued research into the mechanisms of N. fowleri pathogenicity and therapeutic approaches is imperative to combat this lethal infection effectively.

    Understanding the detailed mechanisms by which N. fowleri attaches to the nasal mucosa is crucial for comprehending the initial stages of Primary Amoebic Meningoencephalitis pathogenesis. By elucidating the roles of amoebostomes, integrins, and fibronectin-binding proteins, we gain insights into potential targets for therapeutic intervention aimed at preventing the amoeba from establishing infection and causing devastating CNS disease.

    INTRODUCTION TO MIT EXPLANATIONS OF SCIENTIFIC HOMEOPATHY

    Similia similibus curentur means, if symptoms expressed in an individual during a disease condition and the symptoms produced by a drug when applied in healthy individuals appear similar, that particular drug substance could work as a curative agent for that particular patient.  

    Symptoms expressed in an individual during a disease condition and the symptoms produced by a drug when applied in healthy individuals appear similar when the disease-causing substance and the particular drug substance contain similar chemical molecules with similar functional groups, which can bind to similar biological targets, producing similar molecular inhibitions and leading to errors in the same biochemical pathways. These similar chemical molecules can compete each other to bind to the same molecular targets, by their similar molecular conformations or functional groups.

    Disease-causing molecules produce disease by competitively binding with some biological targets in the body, mimicking as natural ligands of those targets due to their conformational similarity. Drug molecules having conformational similarity with disease-causing molecules, can displace them through competitive relationships, thereby alleviating the pathological inhibitions they cause. Modern biochemistry says, if the functional groups of the disease-causing molecules and drug molecules are similar, they can bind to similar molecular targets and elicit similar symptoms.

    Homeopathy utilizes this phenomenon in identifying the similarity between pathogenic molecules and drug molecules by observing the symptoms they produce. Through “Similia Similibus Curentur,” Hahnemann tried to harness this phenomenon of molecular mimicry and molecular competitions to develop into a novel therapeutic method. He theorized that if symptoms produced in healthy individuals by a particular drug when taken in its molecular form are similar to those appearing in a diseased individual, applying the drug in molecular imprinted form could potentially cure the disease.

    Molecular imprints of similar chemical molecules can act as artificial binding pockets for similar substances, neutralizing them due to their mutually complementary conformations. It is evident that Hahnemann observed this competitive relationship between substances affecting living organisms by producing similar symptoms. Due to historical limitations of scientific knowledge available during his time, he could not fully explain this phenomenon in scientific terms.

    Now we are able to explain the ‘similarity’ between drug-induced symptoms and disease-induced symptoms in terms of ‘similarity’ of molecular inhibitions caused by drug molecules and disease-causing molecules arising from the ‘similarity’ of their functional groups. Samuel Hahnemann, the pioneer of homeopathy, formulated his principles during a time when modern biochemistry had not yet emerged. This historical context explains why Hahnemann was unable to describe his observations using contemporary biochemical concepts. Despite these limitations, his foresight into their therapeutic implications was nothing short of genius.

    Homeopathy, or “Similia Similibus Curentur,” is a therapeutic approach grounded in the identification of drug molecules that, due to their similar functional groups, are capable of competing with disease-causing molecules for binding to biological targets. This methodology relies on observing the similarity of symptoms produced by the disease and those the drug can induce in healthy individuals, thereby deactivating the disease-causing molecules through the binding action of molecular imprints derived from the drug. The future recognition of homeopathy as a scientific discipline hinges on our ability to demonstrate to the scientific community that “Similia Similibus Curentur” is based on the naturally occurring phenomenon of competitive relationships between chemically similar molecules, as explained in modern biochemistry. Once this connection is clearly established, homeopathy’s status as a scientific practice will inevitably be recognized.

    Only way the medicinal properties of a drug substance could be transmitted to and preserved in a medium of water-ethanol mixture during homeopathic ‘potentization’ without any single drug molecule remaining in it is by preserving the conformational details of its functional groups by a process of ‘molecular imprinting’, since the conformational properties of functional groups of drug molecules play a decisive role in biomolecular interactions.

    Active principles of homeopathy drugs potentized above 12 c are molecular imprints of ‘functional groups’ of drugs molecules used as templates for potentization process. When introduced into living system as therapeutic agent, these molecular imprints act as artificial binding pockets for the pathogenic molecules having functional groups that are similar to the template molecules used for potentization. As we know, a state of pathology arises when some endogenous or exogenous molecules having functional groups similar to those of natural ligands of a biological target competitively bind to that target and produce molecular inhibitions. Removing these molecular inhibitions amounts to cure. Once you understand this biological mechanism, you will realize that molecular imprints of natural ligands also can act as therapeutic agents by binding to pathogenic molecules that compete with the natural ligands.

    Biological ligands are molecules that bind specifically to a target molecule, typically a larger protein. This interaction can regulate the protein’s function or activity in various biological processes. Ligands can be of different types, including small molecules, peptides, nucleotides, and others. In biochemistry and pharmacology, understanding ligands and their interactions with proteins is crucial for drug design and for understanding cellular signalling pathways.

    Biological ligands can interact with a variety of molecular targets in the body, each playing a critical role in influencing physiological processes. Ligands can activate or inhibit enzymes, which are proteins that catalyze biochemical reactions. For example, many drugs act as enzyme inhibitors to slow down or halt specific metabolic pathways that contribute to disease.

    According to MIT homeopathic perspective, biological ligands potentized above 12c will contain molecular imprints of constituent functional groups. Molecular imprints of drugs that compete with natural biological ligands for same biological targets also could be used, as both of their functional groups will be similar. These molecular imprints could be used as artificial binding pockets to deactivate any pathogenic molecule that create biomolecular inhibitions by binding to the biological target molecules by their functional groups. As per this approach, therapeutics involves identifying the biological ligands implicated in a particular disease condition, preparing their molecular imprints by homeopathic potentization, and administering those molecular imprints as disease-specific formulations.

    Endogenous or exogenous pathogenic molecules mimic as authentic biological ligands by conformational similarity and competitively bind to their natural target molecules producing inhibition of their functions, thereby creating a state of pathology. Molecular imprints of such biological ligands as well as those of any molecule similar to the competing molecules can act as artificial binding pockets for the pathogenic molecules and remove the molecular inhibitions, and produce a curative effect. This is the simple biological mechanism involved in Molecular Imprints Therapeutics or homeopathy. Potentization is the technique of preparing molecular imprints, and ‘similarity of symptoms’ is the tool used for identifying the biological ligands, their competing molecules, and the drug molecules ‘similar’ to them.

    MIT HOMEOPATHY FOR NAEGLERIA FOWLERI INFECTION

    Based on the detailed study of molecular mechanism involved in pathophysiology of the disease, molecular imprints prepared by homeopathic potentization of Naegleria Fowleri Trophozoite up to 30 c potency is the ideal drug recommended by MIT for prevention and treatment of N. Fowleri infection. This preparation will contain molecular imprints of lectin, integrin-like proteins, fbronectin binding proteins, phospholipdases, proteases, neuraminidase etc contained in amoebostomes that play decisive role in pathology. These molecular imprints can effectively prevent the naegleria fowleri from creating a pathologic condition. Molecular imprints of lectin can prevent the initial contact between n fowleri and epithelial cells in nasal mucosa. Molecular imprints of integrin like proteins and fibronectin binding proteins will prevent the pathogens from binding to host cells in nasal epithelium. Molecular imprints of phospholipidases can prevent the cytotoxic processes initiated by the trophozoites, by blocking the breakdown of phospholipids and release of arachidonic acid. Molecular imprints of proteases can prevent the degrading of structural proteins in neuronal and glial cells. Molecular imprints of neuraminidase will block the enzymatic cleavage of sialic acid from glycoproteins and glycolipids, thereby preventing the cytotoxic effects of naegleria fowleri in brain cells.

  • UNDERSTANDING SARCODES IN THE LIGHT OF LIGAND-BASED APPROACH PROPOSED BY MIT HOMEOPATHY

    In homeopathy, we have an important class of drugs called sarcodes derived from animal tissues. From scientific point of view, we have to understand them in terms of the biological ligands they contain. When these sarcodes are potentized, Molecular Imprints of their constituent biological ligands are produced. These molecular imprints play a crucial role as therapeutic agents in homeopathy.

    Bio-molecular interactions are fundamental to all biological processes in the living system, they and occur through the binding of biological molecules with their natural ligands. These include cellular and intercellular receptors, enzymes, and transport molecules. For these interactions to initiate, natural ligands must bind to specific binding or active sites on biological molecules. Pathogenic molecules, which mimic these natural ligands, can bind to these sites, leading to molecular inhibition and pathology.

    Molecular Imprints of natural ligands act as artificial binding sites for these pathogenic molecules, preventing them from causing harm. Thus, molecular imprints of natural ligands, or potentized sarcodes, serve as powerful therapeutic agents.

    Two critical questions arise when considering sarcodes from the Molecular Imprint Theory (MIT) perspective:

    1. How can sarcodes, as natural biological ligands, become pathogenic agents requiring intervention by their own potentized forms?

    2. Will the potentized forms of sarcodes negatively affect their physiological functions, given that potentized drugs can antidote the effects of the same drugs in their crude forms?

    Pituitary hormones, essential for metabolism and enzyme control, are termed the ‘master gland.’ How can they act as pathogenic agents needing potentized pituitary extract intervention Additionally, will using potentized pitutrin as a sarcode disrupt endocrine activities mediated by pituitary hormones?

    Pepsin, crucial for protein digestion, raises concerns about whether administering pepsinum 30 could deactivate pepsin molecules and hinder digestion. If it does not antidote pepsin, how can it act therapeutically?

    Thyroid hormones are vital for metabolic activities. How can they become pathogenic agents requiring potentized thyroidinum? Will potentized thyroidinum hinder biological processes mediated by thyroid hormones?

    To answer these questions, understanding the dynamics of molecular processes in biochemical interactions is crucial. Biological molecules, particularly hormones, signaling molecules (cytokines), neurochemicals, antibodies, and enzymes, engage in two types of interactions:

    1. On-Target Interactions: These occur between natural ligands and their genuine biological targets, essential for unhindered biochemical pathways. These interactions involve, molecular identification and binding through complementary conformational affinity, and actual chemical interaction through perfect charge affinity.

    2. Off-Target Interactions: These are accidental interactions between ligands and incorrect targets with conformational affinity only. Lacking exact charge affinity, these are inhibitory and can deactivate involved biological molecules, leading to pathological states.

    Off-target inhibitions caused by biological molecules can result in a range of pathological conditions. Potentized sarcodes, containing molecular imprints of these molecules, can remove these inhibitions and act as therapeutic agents. This is where the therapeutic importance of molecular imprinted sarcodes in homeopathy lies.

    Molecular Imprints in potentized sarcodes do not interfere with the interactions between natural ligands and their genuine targets because these involve both conformational and charge affinity. Since molecular imprints act only through conformational affinity, they can interfere only in inhibitory off-target interactions. Consequently, potentized sarcodes like thyroidinum 30 or pitutrin 30 will not disrupt essential biochemical processes mediated by their respective hormones. This principle applies to all potentized sarcodes, ensuring their safety and efficacy when used above 12c potency.

    Sarcodes or potentized biological ligands play a significant role in treating various diseases, including those related to metabolic, emotional, psychosomatic, and ontological factors. They can also be part of constitutional prescriptions. Pathogenic molecules cause diseases by mimicking natural ligands and inhibiting biological targets. Molecular Imprints of biological ligands can bind and deactivate these pathogenic molecules, making them vital in homeopathic therapeutics.

    Since pathogenic molecules produce molecular inhibitions and diseases by competitively binding to natural targets of biological ligands, molecular imprints of biological ligands can act as artificial binding pockets for the pathogenic molecules. This is the biological mechanism by which potentized sarcodes or molecular imprinted biological ligands work as powerful therapeutic agents.

    Here is an exhaustive list of important biological Ligands, their functional groups , molecular targets,  biological roles and competing drugs. By preparing molecular imprints of these biological ligands as well as their competing drugs, through the process of potentization, and incorporating them into our therapeutic arsenal, homeopathy will be raised into a new level of its advancement.
