依据已有的研究,preTCR-pΜΗC相互作用是通过preTCRβ与pΜΗC的抗原结合域(α1,α2)。Reinherz/Wang团队首先将preTCR与pΜΗC分别进行简化处理,即仅使用preTCRβ与Kb-t2(鼠源MHC-I的α1,α2),并定点在preTCRβ和Kb-t2上...

The engagement of the T cell receptor (TCR) by a specific peptide-MHC ligand initiates transmembrane signaling to induce T-cell activation, a key step in most adaptive immune responses. Previous studies have indicated that...
The structure of superantigen complexed with TCR and MHC reveals novel insights into superantigenic T cell activation. Nat Commun. 2010; 1 :119.Saline M, Rödström KE, Fischer G, Orekhov VY, Karlsson BG, et al. (2011) The structure of superantigen complexed with TCR and MHC reveals ...
However, it is also clear that this high accuracy is driven by the very conserved structure of the MHC, and that the picture is very different when focusing only on the peptide. To further investigate this, we analysed how the pMHC model accuracy depends on the peptide length and the ...

Receptor (TCR) analysis is carried out, harnessing the principles of the 5'RACE technology. This enables the acquisition of full TCR sequences, facilitating comprehensive studies on the impact of Complementarity Determining Regions 1 and 2 (CDR1/2) on Major Histocompatibility Complex (MHC) affinity...
5). Unlike traditional T cells, CAR T cells recognize antigens independently of MHC presentation due to CAR’s unique structure, containing a transmembrane region with antigen-binding domain and intracellular signaling and co-signaling domains, allowing MHC-independent CAR T cells to bind to their ...
