[Abstract] Antigen-specific T cell-derived induced pluripotent stem cells (iPSCs) have been shown to re-differentiate into functional T cells and thus provide a potential source of T cells that could be useful for cancer immunotherapy. Human Vα24+ invariant natural killer T (Vα24+iNKT) cells are subset of T cells that are characterized by the expression of an invariant Vα24-Jα18 paired with Vβ11, that recognize glycolipids, such as α-galactosylceramide (α-GalCer), presented by the MHC class I-like molecule CD1d. Vα24+iNKT cells capable of producing IFN-γ are reported to augment anti-tumor responses, which affects both NK cells and CD8+ cytotoxic T lymphocytes to eliminate MHC- and MHC+ tumor cells, respectively. Here we describe a ...
[摘要] 抗原特异性T细胞来源的诱导多能干细胞（iPSCs）已显示重新分化为功能性T细胞，从而提供可用于癌症免疫治疗的T细胞的潜在来源。不变性自然杀伤T（Vα24 + iNKT）细胞的人Vα24 + 细胞是T细胞的子集，其特征在于与Vβ11配对的不变Vα24-Jα18的表达，其识别糖脂，如α-半乳糖神经酰胺（α-GalCer），由MHC I类分子CD1d呈递。据报道能够产生IFN-γ的Vα24 + i / KT细胞增加抗肿瘤反应，其影响NK细胞和CD8 +细胞毒性T淋巴细胞以消除MHC - 和MHC + 肿瘤细胞。在这里，我们描述了将人Vα24 + iNKT细胞重编程到iPSC中的鲁棒方案，然后将其重新分化为Vα24 + iNKT细胞（iPS-Vα24功能的iNKT）。我们进一步提供了测定iPS-Vα24 + iNKT细胞活性的方案。背景 以前有报道说，针对晚期非小细胞肺癌（NSCLC）和头颈部癌症的Vα24 + iNKT细胞癌免疫治疗的临床试验显示疗效，耐受性良好（Motohashi et al。等人，2009; Yamasaki等人，2011）。然而，已知来自外周血单核细胞（PBMC）的Vα24 ...
