What Causes Clonal Selection

When an antigen encounters the immune system, its epitopes eventually will react only with B-lymphocytes with B-cell receptors on their surface that more or less fit and this activates those B-lymphocytes. This process is known as clonal selection (Figure 13.1E. 2).

What triggers clonal selection?

Clonal selection: The theory that lymphocytes bear antigen receptors before activation and that random mutations during clonal expansion cause the development of lymphocytes with high binding affinities for their antigens. humoral: Of or relating to the body fluids or humors.

What is clonal selection quizlet?

clonal selection. –antigenic-specific selection of a lymphocyte that activates it to produce clones of effector cells dedicated to eliminating the antigen that provoked the initial immune response. – one clone of cells consists of effector cells, another clone of cells consists of memory cells.
