In conjunctival cytology specimens taken from ten patients with SS_KCS and ten asymptomatic normal controls, significantly increased levels of IL-1α, IL-6, IL-8, TNF-α and transforming growth factor-beta1 (TGF-β1) were found in the conjunctival epithelium of SS patients when compared to controls (P < 0.05) and the concentration of IL-6 protein was significantly higher in SS conjunctiva samples (P= 0.012). Here, IL1A is linked to synovial sarcoma.
