| Outline of Final Research Achievements |
In previous study we found abundant distribution of natural helper cell (NH cell) in lacrimal gland. We investigated the roles of NH cells for the ocular surface pathology by removing extra orbital lacrimal gland tissue in mouse, and then made ragweed induced experimental allergic conjunctivitis. We found that lacrimal gland excision did not affect the number of infiltrated eosinophils. On the other hand lacrimal gland excision did induced strong corneal inflammation especially in IL-33 knockout mice. Our results suggested that NH cells and IL-33 may contribute to the homeostasis of ocular surface.
