The fibronectin adhesin of Candida albicans.
Candida albicans possesses on its cell surface an adhesin which binds the whole viable fungus to subendothelial extracellular matrix and matrix proteins. The adhesin is composed of 75 to 80% carbohydrate and approximately 20 to 25% protein by weight. High-performance liquid chromatography of material eluted from a fibronectin-agarose affinity column demonstrates the presence of three peaks, all...
متن کاملMannoprotein Adhesin of Candida albicans Germ Tubes
469 Abstract: The production and detection of a mannoprotein adhesin (MPA) of the hyphalform cells of C. albicans on plastic petri dishes was investigated. Using Concanavalin A-coated latex microspheres, the MPA was detected on the plastic surface on which C. albicans produced germ tubes. The adhesin was extracted using dithiothreitol and iodoacetamide. It did not inhibit the adhesion of the ye...
متن کاملIdentification of Fibronectin Adhesins on Candida albicans
475 Abstract: The pattern of distribution of fibronectin adhesins on yeast and hyphalform Candida albicans was studied with goldlabelled fibronectin and transmission electron microscopy. The germ-tube parts of the hyphal-form cells were the major binding sites for gold-labelled fibronectin, and the attached yeast-cell parts and yeast-form cell remained unlabelled. Therefore, the walls of the ge...
متن کاملFunction of Candida albicans adhesin Hwp1 in biofilm formation.
Hwp1 is a well-characterized Candida albicans cell surface protein, expressed only on hyphae, that mediates tight binding to oral epithelial cells. Prior studies indicate that HWP1 expression is dependent upon Bcr1, a key regulator of biofilm formation. Here we test the hypothesis that Hwp1 is required for biofilm formation. In an in vitro model, the hwp1/hwp1 mutant produces a thin biofilm tha...
متن کاملChemical definition of an epitope/adhesin molecule on Candida albicans.
An antigen (Ag), as defined by reactivity with a monoclonal antibody (mAb 10G), was found on the cell wall surface and on the plasma membrane of Candida albicans yeast cells (Li, R. K., and Cutler, J. E. (1991) J. Gen. Microbiol. 137, 455-464). The 10G Ag from the cell surface location was solubilized by treatment with beta-mercaptoethanol and Zymolyase. Antigenic activity of the extract was lo...
