Generation of hypoimmunogenic T cells from genetically engineered allogeneic human induced pluripotent stem cells
关键词:Hypoimmunogenic iPSC-derived T cells , CAR-modified tKO/E iPSC-T cells,NOG/MHC dKO mice, T cell immunotherapy.
摘要:CAR-T自体治疗已在全球上市几款药物,但临床治疗中只能使用患者自身的细胞,临床治疗成本及细胞的可获得性受到了极大的限制。科学家在积极寻求异体来源的T细胞作为突破口,其中来源于异体的原代T细胞,由于通过多次基因编辑消除移植的T细胞中的HLA和其他免疫激活蛋白,这会导致T细胞发生功能衰竭。 而本次研究中使用了诱导性多能干细胞iPSCs,通过多次基因编辑消除异体因子和激活细胞毒性因子,分化后形成的tKO/E iPSC-T细胞,不仅能避免免疫排斥作用,进一步进行CAR-modified后,在体内外研究中有较强的抗肿瘤活力。文献中表明NOG-dKO(MHC-I- and MHC-II-knockout NOG)小鼠减少异种反应,这将增加iPS-T细胞的观察时间,并且能为iPS-T细胞治疗提供更准确的临床预测。
这些结果表明诱导性多能干细胞iPSCs具有无限的扩展潜力,可以分化成任何细胞类型,包括用于过继性细胞免疫疗法的T细胞。重要的是,它们的扩展和分化潜力都不会受到多次基因编辑的影响。经基因改造的低免疫原性iPSC衍生的T细胞可能有助于现成的T细胞免疫疗法的产生。

Preclinical Activity And Manufacturing Feasibility of Genetically Modified PDCD-1 Knockout(KO) Tumor-infiltrating Lymphocyte(TIL) Cell Thetapy.
关键词:MOCK TIL+ anti-PD-1, PDCD-1 KO TIL, Antitumor Activity, hIL-2 NOG mice,Manufacturing Feasibility
摘要:在2022 AACR 会议上,Lovance Biotherapeutics报道了一款基因修饰的TIL细胞治疗(PDCD-1 KO)的临床前体内治疗效果。利用hIL-2 NOG小鼠,发现PDCD-1 KO TIL的治疗效果远高于MOCK TIL和PD-1联合给药组。表明了内源性的敲除PDCD-1将在TIL治疗中发挥非常重要的作用。同时,分析了PDCD-1 KO TIL在工艺生产中的可行性。这些结果表明PDCD-1 KO TIL(IOV-4001)是一种治疗实体瘤的非常有潜力的临床选择,该项研究即将在黑色素瘤及非小细胞肺癌中开展临床研究。

An ADCC enhanced anti-CCR8 antibody, which preferentially depletes tumor regulatory T cells and inhibits tumor growth
关键词:CCR8,Tregs, CCL1,ADCC,NOG-EXL
摘要:肿瘤相关调节性T细胞(Tregs)可抑制机体的抗肿瘤免疫能力。CCR8在此类Tregs表面高表达,被视为潜在的理想标识靶点。Sound Biologics研发的CCR8单抗,可通过大量消除Tregs来抑制肿瘤生长。与NK细胞疗法联用,ADCC效应增强,还可以促进NK和CD8+T细胞在肿瘤组织内部的浸润,进一步发挥抗肿瘤作用。

A novel humanized mouse model based on NOG-FcγR-/-mice recapitulates anti-tumor immune reactions by human immune systems in response to anti-PD-1 antibody (Nivolumab)
关键词:NOG-FcγR-/-, Fcγ receptors, HSC engraftment, immune checkpoint inhibitors, Nivolumab
摘要:CIEM Japan在NOG小鼠上进行改造得到鼠源FcγRs缺失的NOG-FcγR-/-小鼠,大大减少了鼠源性ADCC效应对肿瘤免疫治疗的潜在影响。对于HSC4、RKO、HCC827和NCI-H1975等癌症,相较于HSC-NOG,PD-1单抗(Nivolumab)在HSC-NOG-FcγR-/-肿瘤模型中可发挥出更强大的肿瘤抑制作用。说明NOG-FcγR-/-可进一步提高免疫疗法的准确性,尤其是与免疫检查点抑制剂的联合疗法。
