N6-methyl-adenosine (m6A) is the most prevalent modification on mRNAs and long noncoding RNAs (lnRNAs) in higher eukaryotes. Modulation of m6A relies on m6A writers, erasers and readers. m6A modification contributes to diverse fundamental biological functions at the molecular, cellular, and physiological levels. The dysregulation of m6A modification has been implicated in various human diseases. Thus, m6A modification has now become a research hotspot for its potential therapeutic applications in the treatment of various cancers and diseases. The immune system is essential to provide defense against infections and cancers. This review summarizes the current knowledge about the roles of m6A in regulating immune cell functions and immune responses. Video abstract.
Keywords: Adaptive; Immunity; Innate; N6-methyl-adenosine; m6A erasers; m6A readers; m6A writers.
