WebbThe clonal selection principle is used to explain the basic features of an adaptive immune response to an antigenic stimulus. It establishes the idea that only those cells that recognize the antigens (Ag's) are selected to proliferate. The selected cells are subject to an affinity maturation process, which improves their affinity to the selective Ag's. This … WebbThe clonal selection theory is a hypothesis which states that individual B-cell lymphocytes express a receptor that is antigen-specific. This would be determined before the antibody ever encounters the antigen. Activation …

The concept was introduced by Australian doctor Visa mer The clonal selection theory can be summarised with the following four tenets: • Each lymphocyte bears a single type of receptor with a unique specificity (generated by V(D)J recombination). • Receptor occupation is required for cell activation.
