Enterocytes'tight junctions play a protective role in limiting invasion of Candida albicans into intestinal cells

National audience; C. albicans is a commensal yeast of the mucous membranes in healthy humans that can also be responsible for disseminated candidiasis, mainly originating from the digestive tract in vulnerable patients. Deciphering the cellular and molecular mechanisms of the interaction of C. albicans with enterocytes is necessary to better understand the basis of commensalism and pathogenicity of the yeast and to improve the management of disseminated candidiasis. In intestinal epithelia, E-cadherin is constitutive of the Adherens Junctions localized just below the Tight Junctions (TJs) which ensure impermeability of the intestinal barrier. We hypothesized the absence of endocytosis of C…
