Gene rearrangement and B-cell development.
The differentiation of B lymphocytes from their progenitors progresses through a series of successive stages that are defined by sequential rearrangement of Ig loci and surface expression of various stage-specific markers, including Ig heavy and light chain proteins. Considerable evidence suggests that the appearance of cells with an orderly progression of Ig gene rearrangements is linked to the expression of the rearranged Ig gene products. Recent experiments have clarified our understanding of mechanisms by which rearrangement of Ig gene segments is controlled and how Ig gene products participate in the regulation of the B-cell differentiation program.
