脊椎动物的T细胞抗原受体可分为αβ或γδ,由TrA/D、TrG或Trb基因座编码。TRs在哺乳动物细胞免疫中起着核心作用,它是通过基因座上V、D、J和C基因的重排而发生的。蝙蝠是唯一具有飞行能力的哺乳动物,被认为是人畜共患病病毒的主要宿主,这是一个重要的公共卫生问题。然而,目前对蝙蝠受体基因的组成知之甚少。根据大马蹄蝠的全基因组序列,参照国际免疫遗传学信息系统(IMGT)制定的TR/IG注释规则,对马蹄蝠的TRA/D、TRG和TRB基因座进行了完整的注释。共注释了128个V片段、3个D片段、85个J片段和6个C片段,并与其他已知的哺乳动物数据进行了比较。分析了铁锈菌的tr基因座和种系基因的特点。
T-cell antigen receptors (TRs) in vertebrates can be divided into αβ or γδ, encoded by TRA/D, TRG, or TRB loci. TRs play a central role in mammal cellular immunity, which occurs by rearrangement of V, D, J, and C genes in the loci. The bat is the only mammal with flying ability and is considered the main host of zoonotic viruses, an important public health concern. However, at present, little is known about the composition of bat TR genes. Based on the whole genome sequence of the greater horseshoe bat (Rhinolophus ferrumequinum) and referring to the TR/IG annotation rules formulated by the international ImMunoGeneTics information system (IMGT), we present a complete annotation of TRA/D, TRG, and TRB loci of R. ferrumequinum. A total of 128 V segments, three D segments, 85 J segments, and 6 C segments were annotated and compared with other known mammalian data. The characteristics of the TR locus and germline genes of R. ferrumequinum are analyzed.
