Background: The fungal genus Sporothrix includes at least four human pathogenic species. One of these species, S. brasiliensis, is the causal agent of a major ongoing zoonotic outbreak of sporotrichosis in Brazil. Elsewhere, sapronoses are caused by S. schenckii and S. globosa. The major aims on this comparative genomic study are: 1) to explore the presence of virulence factors in S. schenckii and S. brasiliens...
The incidence of fungal infections has been increasing in the last decades, while the number of available antifungal classes remains the same. The natural and acquired resistance of some fungal species to available therapies, associated with the high toxicity of these drugs on the present scenario and makes an imperative of the search for new, more efficient and less toxic therapeutic choices. Antimicrobial pep...
Limited information is available regarding the modulation of genes involved in the innate host response to Paracoccidioides brasiliensis, the etiologic agent of paracoccidioidomycosis. Therefore, we sought to characterize, for the first time, the transcriptional profile of murine bone marrow-derived dendritic cells (DCs) at an early stage following their initial interaction with P. brasiliensis. DCs connect inn...
Background: Farnesol is a sesquiterpene alcohol produced by many organisms, and also found in several essential oils. Its role as a quorum sensing molecule and as a virulence factor of Candida albicans has been well described. Studies revealed that farnesol affect the growth of a number of bacteria and fungi, pointing to a potential role as an antimicrobial agent. Methods: Growth assays of Paracoccidioides bras...
Tese (doutorado)—Universidade de Brasília, Instituto de Ciências Biológicas, Departamento de Biologia Celular, 2011.; Nas últimas décadas, a relevância clínica do Reino Fungi vem aumentando, principalmente em virtude da maior incidência de micoses sistêmicas e do número limitado de fármacos eficazes no tratamento de infecções fúngicas. Dentre os fungos de importância médica podemos destacar o fungo dimórfico e ...
Dissertação (mestrado)—Universidade de Brasília, Instituto de Ciências Biológicas, Departamento de Biologia Celular, 2006.; O fungo Paracoccidioides brasiliensis é o agente etiológico da paracoccidioidomicose, a micose sistêmica de maior prevalência na América Latina. O mecanismo mais importante de defesa do hospedeiro contra infecções por P. brasiliensis é a resposta imunológica celular. Esse fungo é capaz de ...
