The anticancer efficacy of conventional chemotherapies seems to be due, in part, to augmentation of the host immune reactivity. However, a new study reveals that two common chemotherapeutic agents, gemcitabine and 5-fluorouracil, can also activate immune regulatory cells, which stimulates the emergence of protumorigenic cytokines via inflammasome pathways, limiting the antitumor efficacy of the drugs (pages 57–64).
常规化疗的抗癌疗效似乎部分归因于宿主免疫反应的增强。然而,一项新的研究表明,两种常见的化疗药物——吉西他滨和 5-氟尿嘧啶——也可以激活免疫调节细胞,这些细胞通过炎症小体途径刺激促肿瘤细胞因子的产生,从而限制了这些药物的抗肿瘤疗效(第 57-64 页)。
