Outline of Final Research Achievements |
Although it is known that type 2 immunity is the main body of allergic inflammation, the detailed mechanism of allergic inflammation evoked by IL-4 or IL-13, signature type 2 cytokines is unclear. We have focused on periostin, an IL-4- or IL-13-inducible product. We, in this study, found that periostin and IL-1alpha produced in fibroblasts and keratinocytes, respectively, co-operatively act on fibroblasts inducing production of IL-6. Moreover, we found that high concentration of periostin is detected in tears of allergic conjunctivitis patients correlated with their clinical severities, suggesting the usefulness of measurement of tear periostin for treatment of allergic conjunctivitis.
