Temperate phages enhance host fitness via RNA-guided flagellar remodeling Bacterial flagella drive motility and chemotaxis while also playing critical roles in host-pathogen interactions, as their oligomeric subunit, flagellin, is specifically recognized by the mammalian im...

Excited to share the work that’s been on my mind for the past 2 years, now on bioRxiv!
Led with Matt Walker, and my first project in the Sternberg Lab .

1/16 New pre-print from the Sternberg Lab!
We uncover how temperate phages can use RNA-guided transcription factors to remodel the flagellar composition of their bacterial host and enhance their fitness.

Sedentary chromosomal integrons as biobanks of bacterial antiphage defense systems Integrons are genetic systems that drive bacterial adaptation by acquiring, expressing, and shuffling gene cassettes. While mobile integrons are well known for spreading antibiotic resistance genes, t...

Our paper is published back2back with one from @amazeld.bsky.social and @epcrocha.bsky.social labs where @baptistedarracq.bsky.social, @eloilittner.bsky.social and co. show that Sedentary Chromosomal Integrons are biobanks of phage defense systems. www.science.org/doi/10.1126/...

Identification of promoter activity in gene-less cassettes from Vibrionaceae superintegrons Abstract. Integrons are genetic platforms that acquire new genes encoded in integron cassettes (ICs), building arrays of adaptive functions. ICs generally encod

And its out! New paper for #integron aficionados. We found gene-less cassettes in superintegrons that express/silence other cassettes in the array. Here is a 🧵(if I know how to do this in Bluesky...😆)
