Elevated rates and biased spectra of mutations in anaerobically cultured lactic acid bacteria | mBio
Despite Earth’s oxygen-free origins and the abundance of microorganisms that thrive without oxygen, little is known about the rates and patterns of mutations in anaerobic species. This study directly ...

A new study provides evidence of a biological mechanism for how Epstein-Barr Virus (EBV) may trigger lupus.

EBV seems to reprogram B-cells at the beginning of a cascade that ultimately results in autoimmunity.

The authors mention that EBV is a cause of MS, and may be related to LongCOVID.
Epstein-Barr virus reprograms autoreactive B cells as antigen-presenting cells in systemic lupus erythematosus
Epstein-Barr virus reprograms autoreactive B cells as antigen-presenting cells to promote pathogenic antinuclear T and B cell responses in lupus.

Excited to share some new work led by grad student Sophie Walton (w/ @petrovadmitri.bsky.social). We used in vitro gut communities to study how natural selection acts on strains of the same species as they compete within larger communities. Check out Sophie's thread below for details!
Super excited that the bulk of my PhD work is now preprinted! Here we used whole-community competition, or coalescence, experiments to quantify selection acting on genetically diverged strains within larger communities. (1/n)

Two PROTAC questions:

1) Does anyone know of a PROTAC for GFP (which could be used to degrade any GFP-tagged protein)?

2) Does anyone have experience with any of the available PROTACs for Halo (like HaloPROTAC3)?

Did you know that it only takes one spontaneous mutation in your bacterial culture to activate a phage, and trigger a subsequent cascade of bacterial/phage evolution? 🧪 Curious how you could detect similar events in your experiments? Check out Nanami’s work!

The combination of Pf repressor mutation happening spontaneously + virome diversification means what you thought were bacterial clones might not be clones, and every colony/overnight might be different! A nightmare when doing experiments but very cool!
TLDR: most P. aeruginosa cells have active, diverse viromes that affect host-pathogen interactions.
➡️ Pf interact with host cells, interfere w/ antibiotics as @prsecor.bsky.social et al have shown.

Dynamics can be FAST! If you don't look carefully, you'll miss it! www.biorxiv.org/content/10.1...

Published in Current Biology! P. aeruginosa can use its filamentous phage to inhibit competitors but high phage production is susceptible to cheater miniphage invasion. Subsequent phage tragedy of the commons can lower bacteria and phage fitness. Link: authors.elsevier.com/c/1lt5I3QW8S...
