Novel adoptive T-cell immunotherapy using a WT1-specific TCR vector encoding silencers for endogenous TCRs shows marked antileukemia reactivity and safety. Serine residues in the cytosolic tail of the T-cell antigen receptor alpha-chain mediate ubiquitination and endoplasmic reticulum-associated degradation of the unassembled protein.Ī minimal binding footprint on CD1d-glycolipid is a basis for selection of the unique human NKT TCR.ĭietary gluten triggers concomitant activation of CD4+ and CD8+ αβ T cells and γδ T cells in celiac disease. MR1-restricted MAIT cells display ligand discrimination and pathogen selectivity through distinct T cell receptor usage.Įfficiency of T-cell receptor expression in dual-specific T cells is controlled by the intrinsic qualities of the TCR chains within the TCR-CD3 complex. Narcolepsy is strongly associated with the T-cell receptor alpha locus. Enhancer sequences have been characterized 4.5kb 3 from TRAC. The total number of human TRA genes per haploid genome is 116 of which 96 to 98 genes are functional.Among the variable genes are included five genes designated as TRAV/DV which belong to five different subgroups and which have been found rearranged either to TRAJ or to TRDD segments and can therefore be used in the synthesis of alpha or delta chains.The potentiel genomic TRA repertoire comprises 45-47 functional TRAV genes belonging to 33-35 subgroups, 50 functional TRAJ segments, and the unique TRAC gene.That deletion occurs in two steps, that is a deletion of the TRD genes, involving specific sequences located upstream from TRDC (sequence pseudo J alpha) would take place before the TRAV-J rearrangement. V-J-rearrangements in the TRA locus therefore result in deletion of the TRD genes localized on the same chromosome. Moreover the TRD locus is nestled in the TRA locus between the TRAV and TRAJ segments.The organization of the TRAJ segments on a large area is quite unusual and has not been observed in the other immunoglobulin or T cell receptor loci.The most 5 TRAV genes occupy the most centromeric position, whereas the TRAC genes, 3 of the locus, is the most telomeric gene in the TRA locus.It consists of 54 TRAV genes belonging to 41 subgroups, 61 TRAJ segments localized on 71 kb, and a unique TRAC gene. The human TRA locus at 14q11.2 spans 1000 kilobases (kb).
