    Mg participates in immune responses in numerous ways: as a cofactor for immunoglobulin synthesis, C'3 convertase, immune cell adherence, antibody-dependent cytolysis, IgM lymphocyte binding, macrophage response to lymphokines, T helper-B cell adherence, binding of substance P to lymphoblasts and antigen binding to macrophage RNA. Mg deficiency in rodents impairs IgG synthesis and cell-mediated immunity; complications include thymus atrophy, elevated IgE, hypereosinophilia, histaminosis and lymphoma. Immunologic sequelae of Mg deficiency in humans are subtle and may be affected by genetic control of blood cell Mg concentration. Abnormal C' activation, excess antibody production and susceptibility to allergy and to chronic fungal and viral infections have been reported. Mg appears to play a protective role in acute allergic reactions.

    Factors Affecting the Risk of Infection

    The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
    The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

    Myasthenia Gravis: Overview and Treatment

    Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
    These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

    Introduction to Lymphatic and Immune System

    Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
    The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...

    Functions of the Lymphatic and Immune System

    The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
    The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

    Special Features of Adaptive Immunity

    The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
    The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
