IL-4 促进免疫疗法的抗药性
卵巢癌具有高度的克隆异质性和免疫抑制的肿瘤微环境(TME),这导致了对免疫疗法的抗药性。现在发表在《细胞》(Cell)上的研究发现,癌细胞产生的IL-4能增强对免疫检查点阻断(ICB)的抵抗力。为了确定影响ICB耐药性和卵巢肿瘤生长的细胞外因素,作者使用一种名为Perturb-map的空间功能基因组学方法评估了参与癌症-巨噬细胞相互作用的特定受体和配体的影响。他们构建了一个针对所选基因的 Pro-Code/CRISPR 文库,每个基因编码一个独特的蛋白质条形码,并将该文库导入小鼠卵巢癌细胞,然后植入免疫功能健全的小鼠体内。癌症衍生的细胞外因子(如 MIF、CCL3、CCL7 和 PLAUR)被证明会影响肿瘤的生长。为了确定参与 ICB 不良反应的基因,作者在注射小鼠生成的肿瘤细胞后,用抗 PD1 治疗小鼠。他们发现,癌细胞衍生的IL-4通过对肿瘤巨噬细胞的作用促进免疫抑制性TME的形成,从而影响肿瘤对ICB的敏感性。这些发现为耐 ICB 的肿瘤提供了一种潜在的治疗方法:细胞 https://doi.org/10.1016/j.cell.2024.10.006 (2024)

期刊介绍: Nature Immunology is a monthly journal that publishes the highest quality research in all areas of immunology. The editorial decisions are made by a team of full-time professional editors. The journal prioritizes work that provides translational and/or fundamental insight into the workings of the immune system. It covers a wide range of topics including innate immunity and inflammation, development, immune receptors, signaling and apoptosis, antigen presentation, gene regulation and recombination, cellular and systemic immunity, vaccines, immune tolerance, autoimmunity, tumor immunology, and microbial immunopathology. In addition to publishing significant original research, Nature Immunology also includes comments, News and Views, research highlights, matters arising from readers, and reviews of the literature. The journal serves as a major conduit of top-quality information for the immunology community.
