Peripheral receptor editing
WebReceptor editing is a process that occurs during the maturation of B cells, which are part of the adaptive immune system. This process forms part of central tolerance to attempt to change the specificity of the antigen receptor of self reactive immature B-cells, in order to rescue them from programmed cell death, called apoptosis. [1] WebMar 1, 2008 · Receptor editing is a key mechanism of B cell tolerance that modifies the B cell receptor (BcR) specificity of self-reactive lymphocytes. ... In peripheral mature B cells, however, editing, called receptor revision, might be driven by the need for receptor diversity, and it acts as a mechanism for expanding the B cell repertoire 21, 22, 23, 24.
