Another study demonstrated that ophthalmitis caused by human SS was efficiently relieved by inhibiting the secretion of macrophage-related inflammatory cytokines interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α), and increasing anti-inflammatory factors interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β) after giving exosomes derived from human umbilical cord mesenchymal stem cells [37]. The gene discussed is TNF; the disease is synovial sarcoma.
