Abstract:
OBJECTIVE:To investigate the distribution and clonality of the T-cell receptor (TCR) V beta repertoire in chronic graft versus host disease (cGVHD). METHODS:The complementarity determining region 3 (CDR3) of the TCR beta gene with 24 variable regions was amplified in peripheral blood mononuclear cells drawn from one cGVHD patient after allogenic bone marrow transplantation (allo-BMT) 35, 39, 43 or 45 months respectively, using RT-PCR, to observe the expression of TCR V beta repertoire T cells. The PCR products were further analyzed by genescan to evaluate clonality of T cells. RESULTS:Fourteen or 16 TCR V beta subfamily T cells were detected in each sample of cGVHD case. Oligoclonal T cells were identified in TCR V beta 6, 16, 17, 19 and 21 subfamilies. The stable clonal T cells in all samples were identified in V beta 6, V beta 17 and V beta 21 subfamilies. CONCLUSION:Skewing distribution and stable clonal expansion of T cells can be found in cGVHD cases and it may be related to the initiation of cGVHD.
