TY - JOUR T1 - The microbiota is a potential mediator of the crosstalk between γδ T cells and tumors AU - Wang, Huidi AU - Li, Jie AU - He, Yan AU - Yin, Jia Y1 - 2022/// JO - Exploration of Immunology VL - 2 IS - 1 SP - 48 EP - 63 DO - 10.37349/ei.2022.00036 UR - https://www.explorationpub.com/Journals/ei/Article/100336 AB - γδ T cells are one of the immune cell types that express antigen receptors. γδ T cells are able to recognize pathogens or cancer cells independently of human leukocyte antigen restriction, which is an important feature of αβ T cells. Therefore, γδ T cells are considered the bridge between innate and adaptive immunity. These cells exhibit important roles in immune surveillance, exert immune defense against tumors and have become promising effector cells for cancer immunotherapy. However, in particular circumstances, the tumor microenvironment seems to render γδ T cells immunosuppressive and even tumor-promoting, emphasizing the importance of regulating γδ T functions in realizing their translation into practical cancer immunotherapy. In recent years, increasing evidence has demonstrated that the intratumoral and peritumoral microbiota can have complex effects on tumor immunology. Thus, understanding the role of microbiota in the crosstalk between γδ T cells and tumors will provide insights for developing adjuvant immunotherapy with precise regulation of tumor-related microbiota. We will discuss the effects of microbiota on γδ T cells that might shape the T cell receptor repertoire and dissect the roles of microbiota in some common tumors, with implications for future cancer therapy.
