MIR155HG and Autoimmunity: We reported that human MIR155HG encodes miPEP155 that suppresses antigen presentation in dendritic cells during autoimmunity (Niu et al, 2020); mouse mir31hg encodes miPEP31 that acts as a transcriptional repressor, inhibiting the expression of the pro-inflammatory miRNA-31 (Zhou et al, 2022).
