Here, de Sá et al. show that Gasdermin-D is transiently activated in Leishmania-infected macrophages and promotes NLRP3 inflammasome activation, but not cell death. Gasdermin-D is cleaved into a noncanonical fragment, indicating that Leishmania subverts Gasdermin-D-mediated host response to establish leishmaniasis.
