Molecular events that regulate alphabeta versus gammadelta T cell lineage commitment: old suspects, new players and different game plans.

abstract：:V(D)J recombination in B and T cells is required for the generation of receptors with a broad spectrum of specificity to foreign antigen. A total number of three immunoglobulin (Ig) and four T cell receptor (Tcr) loci can be targeted by the recombinase enzyme (RAG1/2) in a defined series of recombination events, which...
