The Immunological Basis for Allergies in Mammals

Allergies in mammals occur due to many reasons, viz. due to dietary infections or infections caused by administered medicines. Allergic responses involve the relaxation and contraction of involuntary muscles and the release of substances that are mediators of inflammation, and swelling. The mediators are part of the immunological basis for allergies in mammals, in addition, to several other connective tissue constituents. These constituents include the release of thromboxanes and antigens which form apart of the defence system of mammals. It's a known fact that complement, a group of blood circulatory proteins, bind to these substances and antigens in mammals to help combat these allergies. In this paper, the immunological basis for allergies in mammas is commented on. The discussion that follows considers the major histocompatible complex; of Homo sapiens, animals and birds.
