It is the study of Immune system.
Living systems are made up of Proteins .They are the dehydration polymers of amino acids.Each amino acid residue is joined by a peptide linkage to form proteins. Proteins are the molecular instruments in which genetic information is expressed, Hormones, Antibodies,transporters, the lens protein, the architectural framework of our tissues and a myriad of substances having distinct …
Body proteins perform a large number of functions. One such unique function is, they act as biological catalysts (Enzymes) .They are responsible for highly complex reactions. They direct the metabolic events and exhibit specificity toward substrates, regulate the entire metabolism.Thus, they play key role in the degradation and synthesis of nutrients, biomolecules etc. The most …
Immune deficiency is a condition in which the system fails to protect the host from disease causing agent or from malignant cells. Immune deficiency or immune deficiency is a state in which the immune systems ablity to fight infectious disease is compromised or entirely absent. Two types of immune deficiency Primary/congenital/inherited immunodeficiency:- It results from …
Generalizations T-cells recognize foreign protein antigens if these are displayed within the cleft of MHC displayed on the PM. The protein antigen must be degraded into peptides by a sequence of events called antigen processing. The degraded peptides then associate with MHC molecules with the cell interior and this peptide-MHC complex is transported to the …
Definition: Hypersensitive reactions are inflammatory reactions within the humoral or cell-mediated branches of the immune system that lead to extensive tissue damage or even death. The four types of hypersensitive reactions (Gell and Coombs classification) generate characteristic effector molecules and clinical manifestations Type I Hypersensitive Reaction It is mediated by IgE antibodies whose Fc portion …

The mechanism used by the body as protection against environmental agents that foreign to the body. Immunity is a state of protection against foreign pathogens or substances (antigens). It responds to threats on an individual basis. Term immunity derived from – Immunis, meaning Exempt. Immune system is remarkably versatile defense system that has evolved to …
