Distinct effect of calorie restriction between congenic mating types of Cryptococcus neoformans.

Cryptococcus neoformans (Cn) is an opportunistic yeast that causes meningoencephalitis in immunocompromised individuals. Calorie restriction (CR) prolongs Cn replicative lifespan (RLS) and mimics low-glucose environments in which Cn resides during infection. The effects of CR-mediated stress can differ among strains and have only been studied in MATα cells.

Novel ABC Transporter Associated with Fluconazole Resistance in Aging of .

causes meningoencephalitis in immunocompromised individuals, which is treated with fluconazole (FLC) monotherapy when resources are limited. This can lead to azole resistance, which can be mediated by overexpression of ABC transporters, a class of efflux pumps. ABC pump-mediated efflux of FLC is also augmented in 10-generation old cells.
