Immune response genes in chickens: the multifarious responsiveness to (T,G)-A--L
Abstract:
Immune response in chickens to the multichain copolymer (T,G)-A--L 2030 is analysed. Previous work has shown that responsiveness is not linked to the B-complex. Three different antibody specificities could be distinguished. From the data it is proposed that the response to the backbone of (T,G)-A--L (poly-DL-alanine) influences the responses to the side chain determinants (primarily the (T,G)-determinant). Thus the anti-(T,G) response in chickens is determined by at least two different loci, the B-complex, and another, as yet unidentified locus which determines the response to the poly-DL-alanine determinant. A third antibody specificity is directed against G-A--L and is only detectable in chickens which are high responders to poly-DL-alanine.

Special Features of Adaptive Immunity
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,...

Antigens Involved in Adaptive Immunity
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
