albicans strains lacking this toxin do not activate or damage epithelial cells and are avirulent in animal models of mucosal infection.

Toxin-mediated membrane permeabilization is enhanced by a positively charged C-terminus and triggers an inward current concomitant with calcium influx. This secreted toxin directly damages epithelial membranes, triggers a danger response signaling pathway and activates epithelial immunity. Here we identify the first fungal cytolytic peptide toxin in the opportunistic pathogen Candida albicans. Until now human pathogenic fungi were not known to possess such toxins. albicans.Ĭytolytic proteins and peptide toxins are classical virulence factors of several bacterial pathogens which disrupt epithelial barrier function, damage cells and activate or modulate host immune responses. We propose the name 'Candidalysin' for this cytolytic peptide toxin a newly identified, critical molecular determinant of epithelial damage and host recognition of the clinically important fungus, C. Membrane permeabilization is enhanced by a positive charge at the carboxy terminus of the peptide, which triggers an inward current concomitant with calcium influx. This secreted toxin directly damages epithelial membranes, triggers a danger response signalling pathway and activates epithelial immunity. Here we identify the first, to our knowledge, fungal cytolytic peptide toxin in the opportunistic pathogen Candida albicans. Such toxins have not been identified previously in human pathogenic fungi.
