Although treatment with taxanes does not always lead to clinical benefit, all patients are at risk of their detrimental side effects such as peripheral neuropathy. Understanding the in vivo mode of action of taxanes can help design improved treatment regimens. Here, we demonstrate that in vivo, taxanes directly trigger T cells to selectively kill cancer cells in a non-canonical, T cell receptor-independent manner. Mechanistically, taxanes induce T cells to release cytotoxic extracellular vesicles, which lead to apoptosis specifically in tumor cells while leaving healthy epithelial cells intact. We exploit these findings to develop an effective therapeutic approach, based on transfer of T cells pre-treated with taxanes ex vivo, thereby avoiding toxicity of systemic treatment. Our study reveals a different in vivo mode of action of one of the most commonly used chemotherapies, and opens avenues to harness T cell-dependent anti-tumor effects of taxanes while avoiding systemic toxicity.

紫杉烷通过诱导非典型 T 细胞的细胞毒性来触发体内癌细胞杀伤



尽管紫杉烷类药物治疗并不总能带来临床益处,但所有患者都面临着其有害副作用的风险,例如周围神经病变。了解紫杉烷类药物的体内作用模式有助于设计改进的治疗方案。在这里,我们证明在体内,紫杉烷类药物以非典型的、不依赖于 T 细胞受体的方式直接触发 T 细胞选择性杀死癌细胞。从机制上讲,紫杉烷类药物诱导 T 细胞释放细胞毒性细胞外囊泡,从而导致肿瘤细胞凋亡,同时保持健康上皮细胞完整。我们利用这些发现开发一种有效的治疗方法,该方法基于用紫杉烷类药物离体预处理的 T 细胞的转移,从而避免全身治疗的毒性。我们的研究揭示了最常用化疗之一的不同体内作用模式,并为利用紫杉烷类 T 细胞依赖性抗肿瘤作用同时避免全身毒性开辟了途径。
