In vivo induction of neutrophil chemotaxis by secretory aspartyl proteinases of Candida albicans

Secretory aspartyl proteinases (Saps) of Candida albicans are key virulence traits which cause inflammasome-dependent, aseptic inflammation in a mouse model of vaginitis. In this paper, neutrophil migration in response to Sap2, Sap6 and chemo-attractive products released from Sap-treated vaginal epithelium was measured in vitro, ex vivo and in vivo. Our results show that Sap2 and Sap6 induce ne...

Secretory Aspartyl Proteinases Cause Vaginitis and Can Mediate Vaginitis Caused by Candida albicans in Mice

UNLABELLED Vaginal inflammation (vaginitis) is the most common disease caused by the human-pathogenic fungus Candida albicans. Secretory aspartyl proteinases (Sap) are major virulence traits of C. albicans that have been suggested to play a role in vaginitis. To dissect the mechanisms by which Sap play this role, Sap2, a dominantly expressed member of the Sap family and a putative constituent o...

Three distinct secreted aspartyl proteinases in Candida albicans.

The secreted aspartyl proteinases of Candida albicans (products of the SAP genes) are thought to contribute to virulence through their effects on Candida adherence, invasion, and pathogenicity. From a single strain of C. albicans (WO-1) which expresses a phenotypic switching system, three secreted aspartyl proteinases have been identified as determined by molecular weight and N-terminal sequenc...

Aspartyl proteinases of Candida albicans and their role in pathogenicity.

Among the putative virulence factors of Candida albicans, secreted aspartic proteinases (Sap, encoded by a family of at least nine genes) continue to attract the attention of many investigators studying the pathogenesis of candidiasis. Several early studies documented a correlation between the levels of Sap secretion and the virulence of different strains, but much stronger support for this rol...
