The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
Humans have both an "innate" and an "adaptive" immune system. There are a number of proteins circulating in the blood as part of the complement system that belongs to the innate immune system (although the adaptive system can activate it as well). Normally, the complement proteins are inactive. When the immune system detects some threat, the complement system is triggered and the circulating proteins are chemically split into smaller components. C3 convertases are chemicals that cleave C3 complement into breakdown products in both the "classical" and the "alternative" pathways of the complement system.
Cell signaling is part of a complex system of communication that governs all cellular activities.Issues such as homeostasis, tissue repair, and immunity are all affected by the cell signaling pathways.When the pathways are interrupted, or errors are produced in this process, diseases like cancer, autoimmunity, and diabetes may develop.Glutathione plays a positive role in the cell signaling pathways, and works on a cellular level to improve immune function, communication, and neutralize oxidative stress.In this way the role of glutathione in cell signaling pathways is a positive one. Much more research has been done on this role that involves much more complex terminology.
Specific immunity is also known as adaptive immunity or acquired immunity active or passive. There are two types of specific immune responses; humoral and cell mediated. Humoral immunity is mediated by B Lymphocytes that produce antibodies; forms of B lymphocytes are IgG, IgM, IgA, IgE. They primarily attach bacterial invaders Cellular immunity is mediated by T Lymphocytes and combat intracellular infections (such as viruses), monitor cellular disruptions like tumors or foreign tissues, and fight fungal infections.
