Immunoglobulin isotype switching happens:
WitrynaSince the discovery that isotype switching is mediated by a somatic rearrangement event, progress in the field of isotype switching has come a long way: switch factor activity for several T-cell-derived cytokines has been discovered. The mechanism of action of these switch factors seems to be relate … WitrynaFirst, all isotype switch recombination is productive; second, it uses different recombination signal sequences and enzymes; third, it happens after antigen stimulation and not during B-cell development in the …

Witryna23 lip 2012 · The fact that isotype switching can alter the affinity and/or specificity of an Ab implies that primary and secondary responses could originate from different B-cell populations and that isotype switching could lead to loss of reactivity for the original epitope while gaining novel specificity.
