Mutations that impact immune cell migration and result in immune deficiency illustrate the importance of cell movement in host defense. In humans, loss-of-function mutations in DOCK8, a guanine exchange factor involved in hematopoietic cell migration, leads to immunodeficiency and, paradoxically, allergic disease. Here, we demonstrate that, like humans, Dock8−/− mice have a profound type-2 CD4+ T helper cell (Th2) bias upon pulmonary infection with Cryptococcus neoformans and other non-Th2 stimuli. We found that recruited Dock8−/− CX3CR1+ mononuclear phagocytes are exquisitely sensitive to migration-induced cell shattering, releasing IL-1β that drives GM-CSF production by CD4+ T cells. Blocking IL-1β, GM-CSF, or caspase activation eliminated the type-2 skew in mice lacking DOCK8. Importantly, treatment of infected wild-type mice with apoptotic cells significantly increased GM-CSF production and Th2 differentiation. This reveals an important role for cell death in driving type-2 signals during infection, which may have implications for understanding the etiology of type-2 CD4+ T cell responses in allergic disease.
