摘要

T cell receptors (TCR) diversity is known to serve as a defining hallmark of the antigen-reactive T cell repertoire. Complementarity determining region 3 (CDR3) was the most important region for the recognition of peptide-major histocompatibility complex (MHC) complexes and represented the diversity of TCR repertoire. In this study, we detected the CDR3 spectratypes by complexity scoring system to assess TCR repertoire diversity and further analyzed the correlation of CDR3 score with CD8 + T cell function and with the prognosis of chronic hepatitis C virus (HCV)-infected patients. The results demonstrated that CDR3 score was related to CD8 + T cell function and prognosis by analyzing the clinical indicators such as viral load (VL), rapid virologic response (RVR), early virologic response (EVR) and sustained virologic response (SVR). Importantly, we found that V beta 27, a member of CDR3 subfamily, might play an important role in the clearance of HCV. These findings indicate that TCR diversity maybe serve as a biomarker to predict the clinical parameters of HCV-infected patients.
