CohortAnimals. Isogenic male C57Bl/6 mice from wild-type (WT), CD1d-/-, and iNKT-deficient strain (Jα18-/-), aged 8– 12 weeks, were obtained from the Animal Care Facility at the Federal University of São Paulo (UNIFESP). The C57Bl/ 6 Jα18-/- strain was a gift from Dr. Masaru Taniguchi at the RIKEN Research Center for Allergy and Immunology (Japan)

Disease Introduction MechanismParacoccidioidomycosis (PCM) is caused by a fungus from the Paracoccidioides genus and is considered one of the high-est causes of mortality among Brazilian systemic mycoses. Clinical studies demonstrated a relationship between the characteristics of the immune response and disease severity. In humans, a prominent Th1 response is associated with infection without disease, the chronic form of the disease with Th1/Th17 immunity, and the most severe manifesta-tion, the acute or juvenile form, shows a prominent Th2/Th9 profile. These data are supported by murine models of P. brasiliensis infection showing the association between the classical Th1 immune response, with high levels of IL-2 and IFN-γ, with resistance against the fungi.
