肥胖已被证明会增加许多不同疾病的风险,包括癌症。此外,肥胖还与免疫功能障碍有关,这可能与其他合并症密切相关。最近,人们发现免疫系统受到新陈代谢变化的严重调节。特别是,T细胞能够响应内在的代谢调节机制,以及外部因素,如代谢物可用性的变化。因此,肥胖造成的功能失调的代谢环境可能直接影响T细胞的反应。在这篇综述中,我们重点介绍了T细胞生物学和肥胖领域的最新发现,重点关注T细胞功能障碍的机制以及对癌症免疫治疗的潜在影响。
Obesity has been shown to increase risk for a number of different disorders, including cancer. In addition, obesity is also associated with immune dysfunction, which could contribute to its strong association with other comorbidities. Recently, the immune system has been found to be heavily regulated by changes in metabolism. In particular, T cells are able to respond to intrinsic metabolic regulatory mechanisms, as well as extrinsic factors such as the changes in metabolite availability. The dysfunctional metabolic environment created by obesity could therefore have a direct impact on T cell responses. In this review, we highlight recent findings in the fields of T cell biology and obesity, with a focus on mechanisms driving T cell dysfunction and potential implications for immunotherapeutic treatment of cancer.
