【 摘 要 】

The microbiota, which consists of commensal bacteria, fungi, and viruses, limits the colonization of pathogens at barrier tissues and promotes immune homeostasis. The latter is accomplished through the induction and regulation of both innate and adaptive immune responses. Innate lymphocytes, which include the type‐1 innate lymphoid cell (ILC1), NK cell, type‐2 innate lymphoid cell (ILC2), type‐3 innate lymphoid cell (ILC3), and lymphoid tissue inducer (LTi) cell populations, and innate‐like lymphocytes, such as NKT cells, mucosal‐associated invariant T (MAIT) cells, and γδ T cells, are uniquely capable of responding to the microbiota due to their tissue localization and rapid primary responses. In turn, through their effector functions, these lymphocyte populations modulate the composition of the microbiota and maintain the segregation of commensals. This review will focus on how innate and innate‐like lymphocytes mediate the crosstalk with the microbiome.
