Abstract Heat-shock proteins are molecules with extensive data showing their potential as immunomodulators of different types of diseases. The gene of HSP65 from Mycobacterium leprae has shown prophylactic and immunotherapeutic effects against a broad arrays of experimental models including tuberculosis, leishmaniasis, arthritis and diabetes. With this in mind, we tested the DNAhsp65 vaccine using an experimental model of Paraccocidiodomycosis, an important endemic mycosis in Latin America. The intramuscular immunization with DNAhsp65 induced, in BALB/c mice, an increase of Th1-levels cytokines and a reduction of fungal burdens resulted in a marked reduction of collagen and lung remodeling. DNAhsp65 may be an attractive candidate for prevention, therapy and as an adjuvant for mycosis treatment. This article was published in Vaccine and referenced in Journal of Vaccines & Vaccination
