Abstract

An important initial step in biofilm development and subsequent establishment of fungal infections by the human pathogen Candida glabrata is adherence to a surface. Adherence is mediated through a large number of differentially regulated cell wall-bound adhesins. The fungus can modify the incorporation of adhesins in the cell wall allowing crucial adaptations to new environments. In this study, expression and cell wall incorporation of C. glabrata adhesins were evaluated in biofilms cultured in two different media: YPD and a semi-defined medium SdmYg. Tandem mass spectrometry of isolated C. glabrata cell walls identified 22 proteins including six adhesins: the novel adhesins Awp5 and Awp6, Epa3 and the previously identified adhesins Epa6, Awp2 and Awp4. Regulation of expression of these and other relevant adhesin genes was investigated using real-time qPCR analysis. For most adhesin genes, significant up-regulation was observed in biofilms in at least one of the culturing media. However, this was not the case for EPA6 and AWP2, which is consistent with their gene products already being abundantly present in planktonic cultures grown in YPD medium. Furthermore, most of the adhesin genes tested also show medium-dependent differential regulation. These results underline the idea that many adhesins in C. glabrata are involved in biofilm formation and that their expression is tightly regulated and dependent on environmental conditions and growth phase. This may contribute to its potential to form resilient biofilms and cause infection in various host tissues.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
