A distinct wave of human T cell receptor gamma/delta lymphocytes in the early fetal thymus: evidence for controlled gene rearrangement and cytokine production.

Abstract excerpt

The rearrangement and expression of human T cell receptor (TCR)-gamma and -delta gene segments in clonal and polyclonal populations of early fetal and postnatal human TCR-gamma/delta thymocytes were examined. The data suggest that the TCR-gamma and -delta loci rearrange in an ordered and coordinated fashion. Initial rearrangements at the TCR-delta locus join V delta 2 to D delta 3, and initial rearrangements at...
