Considering that rno-miR-30b-5p may regulate IL-10 and TLR 4 expressions and thus influence the occurrence and development of uveitis, in the present study, we verified the regulatory effect of rno-miR-30b-5p on the IL-10 and TLR 4 expressions using dual luciferase reporter system and investigated the regulatory influence of rno-miR-30b-5p on the expressions of IL-10 and TLR 4 of T lymphocytes from EAU rats in vitro. Here, IL10 is linked to uveitis.
