Very cool new paper on a genetically encoded redox sensor in Cryptococcus neoformans: pubs.acs.org/doi/full/10....

These kind of approaches can enable so many cool experiments with real time monitoring!

Great work, @ubcmicroimmuno.bsky.social
Genetically Encoded Sensors for Monitoring Intracellular Redox Health of the Pathogenic Fungus Cryptococcus neoformans
Redox sensing and regulation are critical to both the survival and virulence strategies used by the pathogenic fungus Cryptococcus neoformans to evade host immunity and establish infection. However, the precise genetic and biochemical mechanisms driving these redox regulation systems in the context of fungal virulence are unclear. To address this limitation, we designed genetically encoded redox sensors optimized for expression in C. neoformans and linked these sensors to cryptococcal redox proteins for real-time monitoring of intracellular redox status. Using these sensors, we established several fluorescence-based techniques for monitoring dose-responsive changes in the intracellular oxidation status of C. neoformans under stress. Specifically, we demonstrated sensor responsiveness to nontoxic doses of peroxide stress and during different stages of cell growth, and we verified sensor responsiveness in a mutant with known sensitivity to oxidative stress. This approach provides a framework for developing and deploying biosensors in pathogenic fungi and in basidiomycetes─a group of microorganisms with relatively few sophisticated genetic tools for molecular and synthetic biology. Overall, our sensors enable real-time insights into the key redox mechanisms driving growth and survival of a globally important pathogen and pave the way for tool development in other fungi.

How do cells clean up misfolded proteins when they divide?

This study finds that the cleanup crew includes the ER chaperone BiP and the proteasome, and kicks in right as cells finish dividing. Surprisingly, one major cell cycle regulator isn’t involved.
