The identified TCR was delivered to Jurkat T cells and primary human T cells (NLGN4X-TCR-T). Functional profiling of NLGN4X-TCR-T was performed by flow cytometry and cytotoxicity assays. Therapeutic efficacy of intracerebroventricular NLGN4X-TCR-T was assessed in NOD scid gamma (NSG) major histocompatibility complex (MHC) I/II knockout (KO) (NSG MHC I/II KO) mice bearing NLGN4X-expressing experimental gliomas.An HLA-A *02-restricted vaccine-induced T cell receptor specifically binding NLGN4X131-139 was applied for therapeutic use. Reactivity, cytotoxicity, and polyfunctionality of this NLGN4X-specific TCR is demonstrated in various cellular models. Intracerebroventricular administration of NLGN4X-TCR-T prolongs survival and leads to an objective response rate (ORR) of 44.4 LB - PUB:(DE-HGF)16 C6 - pmid:37715782 DO - DOI:10.1093/neuonc/noad172 UR - https://inrepo02.dkfz.de/record/282891 ER -
