In the present study we identified and characterized the novel sHsp Hsp21 of the human fungal pathogen Candida albicans. Using a reverse genetics approach

Hsp21 was found in several pathogenic Candida species but not in humans. This prompted us to investigate the effects of a broad range of different antifungal drugs on an Hsp21-null C. albicans mutant strain. Our results indicate that combinatorial therapy targeting Hsp21, together with specific antifungal drug targets, has strong synergistic Hsp21 and SUT2 protein sequences revealed 12.7% identity between both proteins. In contrast, C. albicans Hsp21 shares 96%, 53%, 40%, and 38% identity with uncharacterized proteins from Candida dubliniensis, Candida tropicalis, Candida parapsilosis, and Candida orthopsilosis, respectively, and 39% identity with the Hsp21 was found in several pathogenic Candida species but not in humans. This prompted us to investigate the effects of a broad range of different antifungal drugs on an Hsp21-null C. albicans Small heat shock proteins (sHsps) have multiple cellular functions. However, the biological function of sHsps in pathogenic microorganisms is largely unknown. In the present study we identified and characterized the novel sHsp Hsp21 of the human fungal pathogen Candida albicans.

Although, Candida albicans (C. albicans) are one of the main etiologic agent for candidiasis, the small heat shock protein 21 (sHsp21) in C. albicans showed its pivotal role for environmental stress adaptation and fungal virulence. In C. albicans Hsp21 is a necessary factor for thermal and oxidative stress tolerance.

Currently, efficient treatment of these In the present study we identified and characterized the novel sHsp Hsp21 of the human fungal pathogen Candida albicans. Using a reverse genetics approach we demonstrate the importance of Hsp21 for resistance of C. albicans to specific stresses, including thermal and oxidative stress.

Candida är en jästsvamp som kan orsaka stora besvär över hela kroppen. Förutom en orolig mage kan det bland annat leda till svamp i munnen och på tungan där en obehaglig vit beläggning uppträder. Med hjälp av ett test kan du ta reda på om du är drabbad. Och funkar verkligen den så kallade candida-dieten som påstår sig lindra besvär? Small but crucial: the novel small heat shock protein Hsp21 mediates stress adaptation and virulence in Candida albicans.

unknown. One study of HSP21 from the pathogenic fungus Candida albicans indicates that sHSPs are directly involved in the adaption to specific stresses and are crucial for the pathogenicity of this fungus (Mayer et al., 2012). Five potential sHSPs have already been identified in the intracellular parasite Toxoplasma gondii.
