Abstract |
To investigate how the human γδ T cell pool is shaped during ontogeny and how it is regenerated after transplantation of hematopoietic stem cells (HSCs), we applied an RNA-based next-generation sequencing approach to monitor the dynamics of the repertoires of γδ T cell antigen receptors (TCRs) before and after transplantation in a prospective cohort study. We found that repertoires of rearranged genes encoding γδ TCRs (TRG and TRD) in the peripheral blood of healthy adults were stable over time. Although a large fraction of human TRG repertoires consisted of public sequences, the TRD repertoires were private. In patients undergoing HSC transplantation, γδ T cells were quickly reconstituted; however, they had profoundly altered TCR repertoires. Notably, the clonal proliferation of individual virus-reactive γδ TCR sequences in patients with reactivation of cytomegalovirus revealed strong evidence for adaptive anti-viral γδ T cell immune responses. |
