WebCentral tolerance develops in immature B cells after they express a functional membrane B cell receptor complex. Immature B cell recognition of self antigens will lead to apoptosis or to receptor editing, whereby a new round of V-D-J recombination in the light-chain genes generates new specificities that are not self-reactive.
