Purpose of reviewTo provide a brief overview of recent progress in microRNA biogenesis and homeostasis, its function in immune system and systemic lupus erythematosus (SLE), as well as successful microRNA-based therapy in vivo.Recent findingsStepwise microRNA biogenesis is elaborately regulated at multiple levels, ranging from transcription to ultimate function. Mature microRNAs have inhibitory effects on various biological molecules, which are crucial for stabilizing and normalizing differentiation and function of immune cells. Abnormality in microRNA expression contributes to dysfunction of lupus immune cells and resident cells in local tissues. Manipulation of dysregulated microRNAs in vivo through microRNA delivery or targeting microRNA might be promising for SLE treatment.SummaryRecent advances highlight that microRNAs are important in immunity, lupus autoimmunity and as potential therapy target for SLE.
