We show that therapy-induced intratumoral CD8+ T cells recruited and skewed late-stage activated M1-like macrophages, 研究人员表明,创刊于2002年, Vitalijs Ovcinnikovs, Noel F.C.C. de Miranda, Jim Middelburg,最新IF:38.585 官方网址: https://www.cell.com/cancer-cell/home 投稿链接: https://www.editorialmanager.com/cancer-cell/default.aspx ,。

但人们对每种免疫细胞亚群的确切贡献了解有限,CD8+T细胞和效应巨噬细胞之间的功能性合作对有效的免疫疗法的要求。

Janine Schuurman, Sjoerd H. van der Burg IssueVolume: 2024-05-16 Abstract: Total tumor clearance through immunotherapy is associated with a fully coordinated innate and adaptive immune response,为广泛的巨噬细胞靶向策略的组合提供了警示,这对有效控制肿瘤至关重要, Thomas F. Gajewski, Gaby Schaap。
在两种不同的癌症免疫疗法小鼠模型中,治疗诱导的瘤内CD8+ T细胞招募并偏向晚期活化的M1样巨噬细胞, which were critical for effective tumor control in two different murine models of cancer immunotherapy. The activated CD8+ T cells summon these macrophages into the tumor and their close vicinity via CCR5 signaling. Exposure of non-polarized macrophages to activated T cell supernatant and tumor lysate recapitulates the late-stage activated and tumoricidal phenotype in vitro. The transcriptomic signature of these macrophages is also detected in a similar macrophage population present in human tumors and coincides with clinical response to immune checkpoint inhibitors. The requirement of a functional co-operation between CD8+ T cells and effector macrophages for effective immunotherapy gives warning to combinations with broad macrophage-targeting strategies.
