Paracoccidioidomycosis (PCM) is a systemic granulomatous disease caused by the fungus Paracoccidioides brasiliensis (Pb). In the murine model of PCM, susceptible (S) mice develop disseminated disease with loose granulomas containing several viable fungi whereas resistant (R) mice show low fungal dissemination and encapsulated granulomas with few numbers of degenerated fungal cells. Here, we report the results of the expression of mRNA of these cytokines, as well as their distribution in the paracoccidioidomycotic granulomatous lesions and a semi quantitative score, that was correlated with the histological and biological data. Overall, our data show that the total area of granulomatous lesions and the relative areas of lesions containing Pb were, respectively, 1.2x and 1.9x more extensive in S than in the R mice. Also, the expression of IFN-γ and TNF-α mRNA was, r.. View More»
