适应性免疫识别是由异源二聚体T细胞受体(TCR)与其同源肽-MHC(pMHC)配体之间的特异性相互作用介导的,准确预测TCR:pMHC相互作用的方法将具有深远的临床、治疗和药学应用。在此,我们回顾了最近的发展预测交叉反应性和抗原特异性的TCR识别。我们讨论了目前的实验和计算方法,以调查交叉反应性和抗原特异性的TCR,并强调如何整合动力学,生物物理和结构特征可能提供有价值的见解,在建模免疫原性。我们进一步强调了这两个相互关联的概念之间的密切关系,以及为了更好地理解T细胞反应性以实现有效的临床应用,需要根据另一个概念来研究每个概念。
Adaptive immune recognition is mediated by specific interactions between heterodimeric T cell receptors (TCRs) and their cognate peptide-MHC (pMHC) ligands, and the methods to accurately predict TCR:pMHC interaction would have profound clinical, therapeutic and pharmaceutical applications. Herein, we review recent developments in predicting cross-reactivity and antigen specificity of TCR recognition. We discuss current experimental and computational approaches to investigate cross-reactivity and antigen-specificity of TCRs and highlight how integrating kinetic, biophysical and structural features may offer valuable insights in modeling immunogenicity. We further underscore the close inter-relationship of these two interconnected notions and the need to investigate each in the light of the other for a better understanding of T cell responsiveness for the effective clinical applications.
