In vitro study of secreted aspartyl proteinases Sap1 to Sap3 and Sap4 to Sap6 expression in Candida albicans pleomorphic forms.
Transition from round budding cells to long hyphal forms and production of secreted aspartic proteases (Saps) are considered virulence-associated factors of Candida albicans. Although plenty of data dealing with Saps involvement in the infection process have been published, Saps expression by the different pleomorphic forms as well as the capacity of C. albicans filaments to express Sap1-6 unde...
متن کاملThe inhibition of Candida albicans secreted aspartyl proteinase by triangular gold nanoparticles
Objective(s): The aim of this study was to synthesize triangular gold nanoparticles, and then to evaluate their capability for inhibition of Candida albicans secreted aspartyl proteinase 2(Sap2).Materials and Methods: To synthesize the nanoparticles, hydrogen tetrachloroaurate and hexadecyl trimethyl ammonium bromide were incubated in presence of Sn(IV) meso-tetra(N-methyl-4-pyridyl) porphine t...
متن کاملA triple deletion of the secreted aspartyl proteinase genes SAP4, SAP5, and SAP6 of Candida albicans causes attenuated virulence.
Secreted aspartyl proteinases (Saps) from Candida albicans are encoded by a multigene family with at least nine members (SAP1 to SAP9) and are considered putative virulence factors important for the pathogenicity of this human pathogen. The role of Sap isoenzymes in the virulence of C. albicans has not yet been clearly established, and therefore, using recent progress in the genetics of this ye...
متن کاملDisruption of each of the secreted aspartyl proteinase genes SAP1, SAP2, and SAP3 of Candida albicans attenuates virulence.
Secreted aspartyl proteinases (Saps), encoded by a gene family with at least nine members (SAP1 to SAP9), are one of the most discussed virulence factors produced by the human pathogen Candida albicans. In order to study the role of each Sap isoenzyme in pathogenicity, we have constructed strains which harbor mutations at selected SAP genes. SAP1, SAP2, and SAP3, which are regulated differentia...
متن کاملQuantitative expression of the Candida albicans secreted aspartyl proteinase gene family in human oral and vaginal candidiasis.
A quantitative real-time RT-PCR system was established to identify which secreted aspartyl proteinase (SAP) genes are most highly expressed and potentially contribute to Candida albicans infection of human epithelium in vitro and in vivo. C. albicans SC5314 SAP1-10 gene expression was monitored in organotypic reconstituted human epithelium (RHE) models, monolayers of oral epithelial cells, and ...
