Clonal selection mcat
WebFrom what I understand, clonal selection happens specifically when there's an antibody-antigen interaction (like when the antibody on a B-cell binds to an antigen on a bacterial cell) during infection. This activates the B-cell (the process is complicated and prob low-yield) which causes it to differentiate into memory B and plasma cells. WebThe clonal selection theory proposes that antigen selects lymphocytes for activation from a population of cells precommitted to produce specific antibody. Implicit in this theory is that antibody-forming cells are monospecific and express cell-surface receptors capable of binding foreign antigens.
