TRAIT

T-cell receptor–antigen interaction database (TRAIT) is a comprehensive database that profiles the interactions between TCRs and antigens. TRAIT was developed to explicitly characterize the interactions between TCRs and antigens by integrating sequences, structures, and binding affinities. TRAIT also offers single-cell-based antigen-specific TCR repertoires and systematically demonstrates interactions between mutations of TCRs and antigens. Additionally, clinical evaluations of antigen-specific TCRs were uniquely provided. Given the recent prominence of T-cell-based immunotherapies in disease treatment, the comprehensive data on TCR–antigen interactions provided by TRAIT are anticipated to better facilitate the discovery and optimization of TCR candidates for immunotherapies.T细胞受体-抗原相互作用数据库（T-cell receptor–antigen interaction database，TRAIT）是一款综合性数据库，旨在收录并梳理T细胞受体 (T-cell receptor) 与抗原之间的相互作用信息。该数据库通过整合TCR与抗原的序列、结构以及结合亲和力数据，实现对二者相互作用的精准表征。此外，TRAIT还提供基于单细胞的抗原特异性T细胞受体库数据，并系统性展示了TCR突变体与抗原之间的相互作用关系。除此之外，该数据库还独有提供抗原特异性TCR的临床评估数据。鉴于近年来基于T细胞的免疫疗法在疾病治疗领域的重要性日益凸显，TRAIT所提供的TCR-抗原相互作用综合数据，有望进一步助力免疫疗法所需候选TCR的筛选与优化工作。
