Comprehensive analysis of T-cell receptor repertoire in patients with acute coronary syndrome by high-throughput sequencing.

ABSTRACT: BACKGROUND:This study aims to investigate the T-cell receptor (TCR) repertoire in patients with acute coronary syndrome (ACS). METHODS:The TCR repertoires of 9 unstable angina patients (UA), 14 acute myocardial infarction patients (AMI) and 9 normal coronary artery (NCA) patients were profiled using high-throughput sequencing (HTS). The clonal diversity of the TCR repertoires in different groups was analyzed, as well as the frequencies of variable (V), diversity (D) and joining(J) gene segments. RESULTS:ACS patients including UA and AMI, showed reduced TCRβ diversity than NCA patients. ACS patients presented higher levels of clonal expansion. The clonotype overlap of complementarity determining region 3(CDR3) was significantly varied between different groups. A total of 10 V genes and 1 J
