Too much of a good thing: Overproduction of virulence factors impairs cryptococcal pathogenicity
April 20, 2021
This article comments on work published by Reuwsaat et al. (mBio, 2021), which identified the transcription factor Pdr802 as essential for Cryptococcus neoformans adaptation to and survival under host conditions both in vitro and in vivo.
A chemical genetic screen reveals a role for proteostasis in capsule and biofilm formation by Cryptococcus neoformans
October 31, 2018
This study demonstrates that the bipolar disorder drug lithium inhibits the formation of key virulence factors, biofilm, and polysaccharide capsule, in Cryptococcus neoformans by dysregulating the ubiquitin/proteasome system, shedding light on the impact of lithium and providing insights into potential alternative pharmaceutical approaches for combating this fungal pathogen.
Breaking the bad: Bacillus blocks fungal virulence factors
October 30, 2017
This article comments on work published by Mayer & Kronstad (mBio, 2017), which identified the soil bacterium, Bacillus safensis as a potent inhibitor of virulence factor production by two major fungal pathogens of humans, Cryptococcus neoformans, and Candida albicans.
