    The Role of IL-17 in Protection against Mucosal Candida Infections.
    J Fungi (Basel) 2017 Sep 27;3(4). Epub 2017 Sep 27.
    Department of Biological Sciences, The University of Toledo, 2801 West Bancroft St., Toledo, OH 43606, USA.
    Interleukin-17 (IL-17) is a proinflammatory cytokine produced by adaptive CD4+ T helper cells and innate lymphocytes, such as γδ-T cells and TCRβ+ "natural" Th17 cells. IL-17 activates signaling through the IL-17 receptor, which induces other proinflammatory cytokines, antimicrobial peptides and neutrophil chemokines that are important for antifungal activity. The importance of IL-17 in protective antifungal immunity is evident in mice and humans, where various genetic defects related to the IL-17-signaling pathway render them highly susceptible to forms of candidiasis such oropharyngeal candidiasis (OPC) or more broadly chronic mucocutaneous candidiasis (CMC), both caused mainly by the opportunistic fungal pathogen .

    The three main oral diseases of humans, that is, caries, periodontal diseases, and oral candidiasis, are associated with microbiome shifts initiated by changes in the oral environment and/or decreased effectiveness of mucosal immune surveillance. In this review, we discuss the role that microbial-based therapies may have in the control of these conditions. Most investigations on the use of microorganisms for management of oral disease have been conducted with probiotic strains with some positive but very discrete clinical outcomes. Read More

    Candida Infections and Human Defensins.
    Protein Pept Lett 2017 ;24(8):747-756
    Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste. Italy.
    Background: Candida species infections are an important worldwide health issue since they do not only affect immunocompromised patients but also healthy individuals. The host developed different mechanisms of protection against Candida infections; specifically the immune system and the innate immune response are the first line of defence. Defensis are a group of antimicrobial peptides, components of the innate immunity, produced at mucosal level and known to be active against bacteria, virus but also fungi. Read More

    Overexpression of Secreted Aspartyl Proteinases 2 or 5 is not sufficient for exacerbation of immunopathology in a murine model of vaginitis.

    The secreted aspartyl protineases of have long been implicated in virulence at the mucosal surface, including contribution to colonization and immunopathogenesis during vulvovaginal candidiasis. In an effort to disentangle hypha-associated virulence factor regulation from morphological transition, the purpose of this study was to determine if overexpression of or in a Δ/Δ/Δ/Δ mutant could restore capacity to cause immunopathology during murine vaginitis to this avirulent hypofilamentous strain. Two similar, yet distinct, genetic approaches were used to construct expression vectors to achieve SAP overexpression and both genetic and functional assays confirmed elevated SAP activity in transformed strains.
