RESUMO

Objective To study the T cells lineage polymorphism of TCR BV CDR3 in the peripheral blood of ankylosing spondylitis (AS) patients,in order to provide experimental basis for the immunological patho-genesis study of AS.Methods Twenty-six subfamilies of CDR3 T cells of TCR BV in the PBMC of AS patients were amplified by RT-PCR method,then TCR BV CDR3 lineages polymorphism were analyzed by immunization scanning spectrum.Results TCR BV CDR3 scanning spectrum of 20 active AS patients showed abnormal distribution peak,including monoclonal,oligoclonal/oligoclonal trend,skewing peak and irregular abnormal peak.Among them,some subfamilies of 18 patients showed oligoclonal/oligoclonal trend expansion,BV16 and BV18 two subfamilies of one case showed monoclonal expansion.Most spectral type of PBMC TCR BV CDR3 in five normal controls showed Gauss distribution.Conclusion TCR BV CDR3 lineage have significant characteristic polymorphism and spectrum drift characteristics in the peripheral blood of AS patients,which further indicate that T cells has plaied an important role in the immunological pathogenesis of AS.Monoclonal/oligoclonal expansion of T cells may be autoreactive T cells in nature and they may be involved in the pathogenesis of AS.

RESUMO

Commonly used tumor markers have poor sensitivity and specificity. A lot of research are being conducted searching for the ideal novel serum markers. There are a large number of tumor-associated autoantibodies in cancer patients's serum. Screening and detecting autoantibodies may be used in the early diagnosis of cancer.
