macrophages are among the most abundant immune cells in the tumor microenvironment, where they are known as tumor-associated macrophages (TAMs). Substantial evidence indicates that TAMs generally play protumoral roles in the primary as well as metastatic sites (Noy and Pollard, 2014). TAMs are also known to interfere with several tumor therapeutic modalities, such as chemotherapy, irradiation, and immunotherapy. In general, depletion of M2-like TAMs or reprogramming them into M1-like phenotype enhances the efficacy of these therapies (Rolny et al., 2011; de Palma and Lewis, 2013; Germano et al., 2013).


概要:本文简单介绍了最近发表在《肿瘤细胞》(Cancer Cell)上的一篇关于如何提高乳腺癌化疗疗效的文章。这篇文章发现了乳腺癌化疗可以导致促肿瘤生长的巨噬细胞数量的增多,这些巨噬细胞可以产生大量的白介素-10(IL-10),从而抑制肿瘤内树突状细胞IL-12的产生,由此抑制具细胞毒性的CD8+ T细胞的功能,最终降低化疗疗效。除此之外,文章还证明了阻断IL-10的功能可以促进乳腺癌化疗效果。这篇文章因此提出了可以降低乳腺癌化疗耐受的一种新的治疗靶点。
