ABSTRACT Life-threatening systemic infections often occur due to the translocation of pathogens across gut barrier and into bloodstream. While microbial host mechanisms permitting bacterial are well characterized, these still unclear for fungal such as Candida albicans , a leading cause nosocomial bloodstream infections. In this study, we dissected cellular C. intestinal epithelia in vitro identified genes associated with process. We show that is dynamic process initiated by invasion...

ABSTRACT Unlike other forms of candidiasis, vulvovaginal caused primarily by the fungal pathogen Candida albicans , is a disease immunocompetent and otherwise healthy women. Despite its prevalence, factors responsible for initiating symptomatic infection remain poorly understood. One hallmarks vaginal candidiasis robust recruitment neutrophils to site infection, which seemingly do not clear fungus, but rather exacerbate symptomatology. Candidalysin, newly discovered peptide toxin secreted C....

Candida albicans is a fungal pathobiont, able to cause epithelial cell damage and immune activation. These functions have been attributed its secreted toxin, candidalysin, though the molecular mechanisms are poorly understood. Here, we identify epidermal growth factor receptor (EGFR) as critical component of candidalysin-triggered responses. We find that both C. candidalysin activate human EGFR receptors candidalysin-deficient mutants induce phosphorylation during murine oropharyngeal...

The fungal pathogen Candida albicans is linked to chronic brain diseases such as Alzheimer's disease (AD), but the molecular basis of anti-Candida immunity remains unknown. We show that C. enters mouse from blood and induces two neuroimmune sensing mechanisms involving secreted aspartic proteinases (Saps) candidalysin. Saps disrupt tight junction proteins blood-brain barrier (BBB) permit invasion. also hydrolyze amyloid precursor protein (APP) into β (Aβ)-like peptides bind Toll-like...

Background. The ability of epithelial cells (ECs) to discriminate between commensal and pathogenic microbes is essential for healthy living. Key these interactions are mucosal responses pathogen-induced damage.

Protection against microbial infection by the induction of inflammation is a key function IL-1 superfamily, including both classical and new IL-36 cytokine families. Candida albicans frequent human fungal pathogen causing mucosal infections. Although initiators effectors important in protective host responses to C. are well described, players driving these remain poorly defined. Recent work has identified central role played inducing innate Type-17 immune clear Despite this, lack signaling...

Candida albicans is an opportunistic fungal pathogen responsible for superficial and life-threatening infections in humans. During mucosal infection, C. undergoes a morphological transition from yeast to invasive filamentous hyphae that secrete candidalysin, 31-amino-acid peptide toxin required virulence. Candidalysin damages epithelial cell plasma membranes stimulates the activating protein 1 (AP-1) transcription factor c-Fos (via p38-mitogen-activated kinase [MAPK]), MAPK phosphatase MKP1...

Vulvovaginal candidiasis (VVC), caused primarily by the human fungal pathogen Candida albicans , results in significant quality-of-life issues for women worldwide. Candidalysin, a toxin derived from polypeptide (Ece1p) encoded ECE1 gene, plays crucial role driving immunopathology at vaginal mucosa. This study aimed to determine if expression and/or processing of Ece1p differs across C . isolates and whether this partly underlies differential pathogenicity observed clinically. Using targeted...
