AIRE and uveitis: To investigate the role of the m6A modification in retinal microglia in the context of uveitis, we first examined the mRNA levels of m6A writers, erasers and readers in microglia using GEO data (GSM3854512-3854519) from single-cell RNA-seq analysis of an Aire–/– spontaneous uveoretinitis mouse model (Heng et al., 2019).
