Our work on understanding how Staphylococcus aureus mode of cell division contributes to pathogenesis is now available in bioRxiv

Orthogonal cell division organizes surface virulence factors to drive staphylococcal abscess community formation www.biorxiv.org/content/10.64898/2026.03...

Systems analysis reveals alternate metabolic states adopted by Mycobacterium tuberculosis across species Mycobacterium tuberculosis (Mtb) persists within macrophages, yet how different host species shape bacterial state remains poorly understood. Here, we directly compared the intracellular transcriptome...

Excited to share our lab's newest preprint (strap in if you're excited about metabolism, species differences, or Mtb gene expression): www.biorxiv.org/content/10.1...

A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics - Nature Microbiology The authors developed a screen to find compounds that modulate intracellular Staphylococcus aureus metabolism and discovered KL1, which sensitizes persisters to antibiotics by reversing host-induced tolerance.

Delighted to share our latest paper - A host-directed adjuvant sensitizes intracellular bacterial persisters to antibiotics. Excellently led by Dr. Kuan-Yi Lu. We think it's a great proof-of-concept that altering immune cell behavior can make antibiotics work better www.nature.com/articles/s41...

Celebrated Kate’s PhD thesis defense today! Huge congrats to the new Dr. Cotten and fantastic job on your seminar and defense!! 😀

Excited to post our first S. aureus preprint on biorxiv! Big congrats to co-first authors, postdocs @anjali20anil.bsky.social and Rezia Braza, and really enjoyed the collaboration with @torreslab.bsky.social !

Big congrats to the new Dr. Cotten @katecotten.bsky.social on the manuscript submission! Preprint is now available on biorxiv, and links a tRNA modification to specific reductions in ribosomal gene expression and antibiotic tolerance. Check it out! 😀

Congratulations Dr. Cotten!! 🥳 @katecotten.bsky.social @davislabjhu.bsky.social

🎉 Congratulations to @johnshopkinssph.bsky.social & @johnshopkinsmmi.bsky.social PhD graduate Kate Cotten, PhD, who successfully defended her PhD thesis!

Way to go, Kate!
