Understanding the structural dynamics of TCR-pMHC interactions

This issue prompted us to reevaluate the extent of TCR cell surface stability, internalization, and recycling. Some early studies suggested that the TCR:CD3 complex

The T cell receptor (TCR) is one of the most complicated receptors in mammalian cells, and its triggering mechanism remains mysterious. As an octamer complex, TCR

Very recently, the determination of the TCR:CD3 complex structure by means of Cryo-EM technique has given a chance to build the entire system essential in the activation of T-cells, a

RMSDs and root-mean-square fluctuations of the complex subunits revealed that the subdomains of the GPa3b17 and WT TCR complexes were stable throughout the simulations , with two local exceptions: one of the

First, the receptor and CD3 signaling modules assemble into complexes that possess a full complement of 10 ITAMs and other key motifs that mediate or regulate signaling through the

The T cell receptor (TCR)-CD3 complex recognizes antigens and transmits signal into the T cell to initiate the adaptive immune response. Natarajan et al. examine the TCR-CD3

To generate a 3D model of the TCR-CD3 complex using cross-linking Full atom, 3D models of the two CD3 hetero-oligomers were docked to a grid potential representation of

Here, we present the first complete model of the pMHC interacting with the TCR:CD3 complex, built in a lipid environment.

T cells are critical for protective immune responses to pathogens and tumors. The T-cell receptor (TCR)–CD3 complex is composed of a diverse αβ TCR heterodimer noncovalently associated

The TCR regulates T cell activation through the linkage of peptide-MHC complex (pMHC) and co The CD3δ chain is loosely bound to the pre-TCR-CD3 complex and the γδ

The cryoEM structure of a fully-assembled TCR–CD3 complex has provided a wealth of new information on its overall molecular architecture and the exact interactions

Starting from the available experimental data on the complex between SEB, the TCR and MHC class II (19), we initially rebuilt a tentative model of the whole SEB-MHCII-TCR-CD3gϵ-CD3dϵ
