摘要: The present invention relates to T cell receptors (TCRs) which bind the HLA-A2 restricted CLGGLLTMV peptide (SEQ ID NO: 1) derived from the LMP2A protein from Epstein Barr Virus (EBY). TCRs of the invention comprise a TCR alpha chain variable domain and/or a TCR beta variable domain. Certain preferred TCRs also bind the natural peptide variants SLGGLLTMV (SEQ ID NO: 17) and CLGGLITMV (SEQ ID NO: 18) presented as a peptide-HLA-A2 complex. The TCRs of the invention demonstrate excellent specificity profiles for those LMP2A epitopes and have binding affinities for the complex which result in an enhanced ability to recognize the complex compared to a soluble reference TCR having the extracellular sequence of the native EBY LMP2A TCR alpha chain given in FIG. 3 (SEQ ID No: 4) and the extracellular sequence of the native EBY LMP2A TCR beta chain given in FIG. 4 (SEQ ID No: 5).
摘要翻译: 本发明涉及结合源自爱泼斯坦巴尔病毒(EBY)的LMP2A蛋白质的HLA-A2限制性CLGGLLTMV肽(SEQ ID NO:1)的T细胞受体(TCR)。 本发明的TCR包含TCRα链可变结构域和/或TCRβ可变结构域。 某些优选的TCR还结合作为肽HLA-A2复合物呈现的天然肽变体SLGGLLTMV(SEQ ID NO:17)和CLGGLITMV(SEQ ID NO:18)。 本发明的TCR证实了对于那些LMP2A表位的优异的特异性谱,并且与具有天然EBY LMP2ATCRα链的细胞外序列的可溶性参考TCR相比,复合物具有增强的识别复合物的能力的结合亲和力,其给出在 图。 3(SEQ ID No:4)和图1中给出的天然EBY LMP2ATCRβ链的细胞外序列。 4(SEQ ID No:5)。

摘要: The present invention relates to binding molecules that comprise T cell receptor (TCR) variable domains and which can bind to a PRAME peptide-HLA complex. In particular, the present invention relates to binding molecules that bind to PYLGQMINL (SEQ ID NO: 1) in complex with HLA-A24. The invention also relates to the use of such molecules for the treatment of malignant diseases.

摘要: The present invention relates to T cell receptors (TCRs) that bind the HLA-A*02 restricted peptide SLLQHLIGL (SEQ ID NO: 1) derived from the germline cancer antigen PRAME. Said TCRs may comprise non-natural mutations within the alpha and/or beta variable domains relative to a native PRAME TCR. The TCRs of the invention are particularly suitable for use as novel immunotherapeutic reagents for the treatment of malignant disease.
