Abstract

Mucosal-associated invariant T (MAIT) cells are evolutionarily conserved T cells that recognize microbial metabolites. They are abundant in humans and conserved during mammalian evolution, which suggests that they have important nonredundant functions. In this article, we discuss the evolutionary conservation of MAIT cells and describe their original developmental process. MAIT cells exert a wide variety of effector functions, from killing infected cells and promoting inflammation to repairing tissues. We provide insights into these functions and discuss how they result from the context of stimulation encountered by MAIT cells in different tissues and pathological settings. We describe how MAIT cell numbers and features are modified in disease states, focusing mainly on in vivo models. Lastly, we discuss emerging strategies to manipulate MAIT cells for therapeutic purposes.
