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...
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.
