Rno-miR-30b-5p is downregulated in spleen, lymph nodes, and eye tissues in rats with experimental autoimmune uveitis, regulates the levels of IL-10 and TLR4, influences both IL-10 and TLR4 positive cell proportion within cell clusters, and thus suppresses the development of uveitis. This evidence concerns the gene TLR4 and autoimmune uveitis.
