A newly discovered molecular switch in Pseudomonas aeruginosa

Characterization of a novel post-transcriptional regulator in P. aeruginosa

NIH-funded research Boston Children's Hospital · NIH-11291869

This project looks at how a newly discovered bacterial protein called PhaF controls Pseudomonas aeruginosa behavior, which matters for people with cystic fibrosis and hospital infections.

What this research studies

Researchers will map which bacterial RNAs and genes are directly controlled by the PhaF protein in a standard lab strain and in clinical P. aeruginosa isolates. They will test PhaF activity during different growth phases and under conditions that mimic infection, and they will look for its targets in an animal model of chronic infection. The team will also test whether PhaF affects biofilm formation and virulence by manipulating its targets. Results will clarify how PhaF controls behaviors that make Pseudomonas hard to treat.

Who could benefit from this research

Good fit: People with chronic Pseudomonas aeruginosa infections—especially those with cystic fibrosis, chronic wounds, or hospital-acquired pneumonia—are the most relevant patient group for this research.

Not a fit: Patients without Pseudomonas infections or those whose illnesses are caused by other microbes are unlikely to benefit directly from this work.

Why it matters

Potential benefit: If successful, this work could point to new ways to disrupt Pseudomonas virulence or biofilms and lead to therapies that help people with cystic fibrosis and other chronic Pseudomonas infections.

How similar studies have performed: Earlier work linking RNA-binding proteins like Hfq and RsmA to Pseudomonas virulence supports the approach, but PhaF is a newly identified regulator and is less well studied.
