Outline of Final Research Achievements |
Group 2 innate lymphoid cells (ILC2) contribute to various immunological diseases including allergic disorders. Therefore, it is urgent to elucidate the activation mechanism of ILC2. In this study, we identified a novel pathway for ILC2 activation via the calcium (Ca2+) signaling pathway. In addition, IL-4 produced by ILC2 via Ca2+ signaling promoted increased allergic susceptibility by inducing antigen-nonspecific IgE production. Taken together, we clarified the mechanism of IL-4 production by ILC2 and the novel role of IL-4-mediated by ILC2 in the pathogenesis of allergy.
