Abstract | PURPOSE: Eotaxin, a CC-chemokine with selective chemotactic effects for eosinophils, has been reported to play an important role in allergic conjunctival diseases. We previously reported that eotaxin is produced by conjunctival fibroblasts and keratocytes on stimulation with Th2 cytokines. Tranilast is known to have anti-allergic properties. In this study, we examined the inhibitory effect of tranilast, an anti-allergic drug, on eotaxin-1 production from cultured conjunctival fibroblasts. METHODS: Conjunctival fibroblasts obtained from normal patients were cultured in DMEM/F12 medium. On the fifth passage, the cells were transferred to a 96-well plate and, after starvation for 24 hr, TNF-alpha, IL-4, and tranilast or dexamethasone were added. After 48 hr, the concentrations of eotaxin-1 in the supernatants were measured by ELISA, and the cells were tested for eotaxin-1 expression by real-time PCR. RESULTS: CONCLUSIONS:
