Phenotypic switching in candida albicans
WebMay 20, 2009 · The white-opaque transition in the opportunistic pathogen Candida albicans provides an excellent example of phenotypic switching in eukaryotes. In this transition, white cells are round and give rise to smooth, domed colonies, whereas opaque cells are bean shaped and give rise to flatter, translucent colonies ( Slutsky et al., 1987 ). WebMar 14, 2024 · Candida albicans is both a common commensal and an opportunistic pathogen, being a prevalent cause of mucosal and systemic infections in humans. Phenotypic switching between white and opaque forms is a reversible transition that influences virulence, mating behavior, and biofilm formation. In this work, we show that a …
Phenotypic switching in candida albicans
Did you know?
WebMost strains of Candida albicans are capable of switching spontaneously and at high frequencies between a number of phenotypes distinguished by colony morphology. Unlike switching in many other microbial pathogens, switching in C. albicans is pleiotropic, affecting several morphological and physiological parameters. WebNov 24, 1999 · Phenotypic switching in the yeast Candida albicans can be controlled by a SIR2 gene. (a) Yeast colonies that are homozygous positive for the SIR2 gene (SIR2/SIR2) have a uniform colony morphology, while those that lack completely SIR2 (homozygous negative (more...)
WebMar 21, 2013 · In Candida albicans, the white-opaque phenotypic switch plays a central role in regulating the program of sexual mating as well as interactions with the mammalian host. White-opaque switching is controlled by genes encoded at the MTL (mating-type-like) locus that ensures that only a or α cells can switch from the white state to the mating ... WebPhenotypic switching in Candida albicans is often used to refer to the epigenetic white-to-opaque switching system. C. albicans needs this switch for sexual mating. [3] Next to the …
WebMay 26, 2016 · In the human fungal pathogen Candida albicans, cells exhibit heritable switching between two phenotypic states, white and opaque, which yield differences in mating, filamentous growth, and interactions with immune cells in vitro. Here, we address the in vivo virulence properties of the two cell states in a zebrafish model of infection. WebNov 24, 1999 · National Center for Biotechnology Information
