Stress-induced phenotypic switching in Candida albicans.
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 wide range of factors induces high rates of switching from white to opaque. T...
متن کاملBlast-induced phenotypic switching in cerebral vasospasm.
Vasospasm of the cerebrovasculature is a common manifestation of blast-induced traumatic brain injury (bTBI) reported among combat casualties in the conflicts in Afghanistan and Iraq. Cerebral vasospasm occurs more frequently, and with earlier onset, in bTBI patients than in patients with other TBI injury modes, such as blunt force trauma. Though vasospasm is usually associated with the presenc...
متن کاملPhenotypic switching in gene regulatory networks.
Noise in gene expression can lead to reversible phenotypic switching. Several experimental studies have shown that the abundance distributions of proteins in a population of isogenic cells may display multiple distinct maxima. Each of these maxima may be associated with a subpopulation of a particular phenotype, the quantification of which is important for understanding cellular decision-making...
متن کاملPhenotypic switching: an opportunity to bacteria thrive
Bacteria in nature are “plagued“ by various unpredictable environmental stresses, being population diversity one of the strategies adopted to survive. Phenotypic switching is one of the evolution processes that causes commutation between phenotypic states. This phenomenon shows up as variation in colony morphology. Alterations in colony morphotype traits may reveal altered cellular basis phenot...
متن کاملPhenotypic switching of populations of cells in a stochastic environment
In biology phenotypic switching is a common bet-hedging strategy in the face of uncertain environmental conditions. Existing mathematical models often focus on periodically changing environments to determine the optimal phenotypic response. We focus on the case in which the environment switches randomly between discrete states. Starting from an individual-based model we derive stochastic differ...
