SSR42 is a novel regulator of cytolytic activity in Staphylococcus aureus | mBio Staphylococcus aureus is a master pathogen due to its formidable collection of virulence factors. These are tightly controlled by a diverse group of regulators that titrate their abundance to adapt to unique infectious niches. The role of regulatory RNAs ...

Super excited to finally have this out! We characterized SSR42 as a novel RNA-based regulator of cytotoxicity in S. aureus. It is capable of responding to a host-like environment to activate the leukocidin LukAB and mediate neutriphil interactions. Check it out! journals.asm.org/doi/10.1128/...
