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 …
