Together these results demonstrate that changes in the activity of regulatory elements located at the TCR beta constant regions are sufficient to redirect the recombination pattern of TCR beta variable gene segments.doi:10.1002/1521-4141(200211)32:113.0.CO;2-9Stéphanie EyquemChantal LagresleMagali Fa...
结果显示,NY-ESO-1特异性TCR-T细胞的扩增增加,T细胞持续9个月,免疫原性最低。类似的研究【CRISPR-based gene disruption and integration of high-avidity, WT1-specific T cell receptors improve antitumor T cell function】也是通过CRISPR-Cas9技术敲除TCR的内源性TRAC和TRBC,避免WT1特异性TCRα/β的错配,并最大...

Disruption of the mouse TCR C delta gene segment by a gene targeting method caused the complete loss of T cells bearing TCR gamma delta chains, but had little or no effect on the development of T cells bearing TCR alpha beta chains. The analyses of TCR gamma and delta genes in the ...

(with both the α and the beta β sequences) were considered, and sequences containing non-standard amino acids were removed. Duplicated TCR–pMHC were merged based on V/J gene usage and CDR3 sequence for both the α- and β-chain. The data analysis was done with Python (v.3.9.7) ...
In the DN3 stage (CD44−, CD25+) TCRβ gene rearrangements occur and the thymocytes undergo beta-selection, which requires that TCRβ chains are produced and capable of pairing with a surrogate α chain, termed pTα, to generate the diversity of preTCRs. Each thymocyte within the αβT-...
