Furthermore, Sun et al. demonstrated that rno-miR-30b-5P expression was decreased in the spleen, lymph nodes and eye tissues of EAU rats, and rno-miR-30b-5P played a role in the pathogenesis of uveitis by directly regulating the levels of IL-10- and TLR4-positive cells to affect the development of uveitis (Sun et al., 2018). Here, TLR4 is linked to uveitis.
