In respond to commensal bacteria: ??T cells play a pleiotropic role in tumor immunity.


ABSTRACT: ??T cells are a mixture of innate programming and acquired adaptability that bridge the adaptive and innate immune systems. ??T cells are mainly classified as tissue-resident V?1 or circulating V?2 ??T cells. In the tumor microenvironment, tumor immunity is influenced by the increased quantity and phenotype plasticity of ??T cells. Commensal bacteria are ubiquitous in the human body, and they have been confirmed to exist in various tumor tissues. With the participation of commensal bacteria, ??T cells maintain homeostasis and are activated to affect the development and progression of tumors. Here, we summarize the relationship between ??T cells and commensal bacteria, the potential protumor and antitumor effects underlying ??T cells, and the new developments in ??T cell-based tumor therapy which is expected to open new opportunities for tumor immunotherapy.
