Based on the Tritope Model of the TCR [Cohn, M., 2005c. The Tritope Model for restrictive recognition of antigen by T-cells. I. What assumptions about structure are needed to explain function? Mol. Immunol. 42, 1419-1443], a set of functional and evolutionary problems surrounding restrictive recognition of antigen are discussed. These include the origin of allele-specific recognition, the selection pressures for polygeneism and polymorphism, the TCR signaling interactions, the centrality of effector T-helper (eTh)-dependence for activation, the role of haplotype exclusion, "nonclassical" MHC-elements, alloreactivity versus xenoreactivity, etc. Further, a set of observations believed to support the Standard Model are reinterpreted.
基于TCR的三表位模型[科恩,M.,2005年c。T细胞对抗原限制性识别的三表位模型。I. 解释功能需要哪些关于结构的假设?分子免疫学。42,1419 - 1443],讨论了围绕抗原限制性识别的一系列功能和进化问题。这些问题包括等位基因特异性识别的起源、多基因性和多态性的选择压力、TCR信号相互作用、效应性辅助性T细胞(eTh)依赖性激活的核心地位、单倍型排斥的作用、“非经典”MHC元件、同种异体反应性与异种反应性等。此外,对一组被认为支持标准模型的观察结果进行了重新解释。
