Excited to share our new preprint on confirming the essentiality of four genes in mating-type locus in Cryptococcus neoformans! MYO2, although predicted to be essential, is dispensable for cell viability and important for cytokinesis and pathogenicity. biorxiv.org/content/10.1101/…

In the latest @PNASNews , we discovered that RNAi-loss is more common than expected in the global population of Cryptococcus neoformans, driving distinct evolutionary paths: hypermutation via transposon accumulation or survival without hypermutation. pnas.org/doi/10.1073/pnas.24…

Check out our latest preprint on RNAi epimutations!🧬biorxiv.org/content/10.1101/… Our team has shown how spontaneous RNAi-based epimutations conferring drug resistance in a human fungal pathogen are transmitted to the next generation following sexual reproduction. More details? ▶️🧵

🚨New Preprint🚨
Can signaling cascades modulate expression status even before turning genes on and off in the nucleus?
We studied and found a direct role of calcium-responsive calcineurin signaling in RNAi at P-bodies, governing gene expression levels.

The latest @PLOSPathogens Pearls article by @VikasYadavSci is now out. He reviews the essential roles of calcineurin in the virulence of #fungal pathogens of animals and plants and discusses what future studies should focus on to target this Achilles heel.

We wrote a review on the importance of stress-responsive calcium-calcineurin signaling in fungal pathogens and how understanding this signaling cascade can be extremely fruitful. Read on -

While the overall incidence of major IFDs and their mortality rate remained relatively stable, the study observed increased fungemia in older population (mainly due to infections by C. albicans), as well as concurrent IFD infections.

The study highlights the importance of active surveillance of IFDs and the collaboration between mycologists and clinicians, and calls for research on innovative approaches to diagnostic tools and new antifungals that can improve the global survival rates associated with IFDs.

Using surveillance data collected by the French National Reference Center for Invasive Mycoses and Antifungals, a recent report in mBio by the French Mycoses Study Group provides an updated comprehensive overview on the epidemiology of invasive fungal diseases (IFDs) in France.
