A short research stay in 2019 (back in the pre-COVID era) at José R. Penadés lab turned into the third chapter of my PhD and today it finally sees the light.

On this fabulous day celebrating André Citroën's birthday 🥖🚗, I’m happy to share my main paper from my postdoc in @jrpenades.bsky.social Lab.
If you want to hear about how plasmid evolution is driven by mobile genetic elements, please come and read this preprint!

A new paper from the lab on virus-like particles called eCISs www.nature.com/articles/s41...

How bacteria evolved thousands of precision nanoinjectors?

Some bacteria don’t secrete toxins — they inject them using phage-derived machines called extracellular contractile injection systems (eCISs).

A prophage-encoded sRNA limits phage infection of adherent-invasive E. coli Author summary Prophages—viral genomes integrated into bacterial chromosomes—are common in enteric bacteria and can profoundly influence bacterial physiology and ecological fitness. Here we show that ...

[1/3] Is your favorite bacterial isolate hiding a surprise lytic virus with a VERY different lifestyle? Finally I can proudly say that our paper on persistent phages is out in Nature Microbiology. rdcu.be/eWJEp. Well done @peterdoug.bsky.social

A family of linear plasmid phages that detect a quorum-sensing autoinducer exists in multiple bacterial species | mBio The discovery of quorum-sensing responsive linear plasmid phages has transformed understanding of phage-bacterial interactions by demonstrating inter-domain chemical communication. To date, however, e...

The final form of my 2nd postdoc paper with the Bassler Lab! Turns out our favorite quorum-sensing phage isn’t a one-off, but rather a member of a globally dispersed family of phages that sense a universal autoinducer.

Phage-encoded small RNA hijacks host replication machinery to support the phage lytic cycle Using RIL-seq, Silverman et al. map the RNA interactome of E. coli during phage lambda infection and uncover a conserved phage-encoded sRNA that activates host replication machinery. Their findings re...

Do viruses use RNA to rewire bacteria?
Yes!
In our paper in @cp-molcell.bsky.social RIL-seq reveals interkingdom RNA interactions during λ infection. Phages don’t just encode proteins, they use small RNAs to hijack bacterial replication and fine-tune infection.

Phages communicate across species to shape microbial ecosystems Arbitrium is a communication system that helps bacteriophages decide between lysis and lysogeny via secreted peptides. In arbitrium, the AimP peptide binds its cognate AimR receptor to repress aimX ex...

Repost = nice. Thank you very much!!!

Amazing Lingchen! Massive congratulations 🎊🤩

We discovered a new horizontal gene transfer mechanism: tail-less cf-PICIs hijack free phage tails extracellularly, forming infectious chimeric virions that drive both intra- and inter-species transfer among bacteria. @jonaszpatkowski.bsky.social @tcostalab.bsky.social @jrpenades.bsky.social

Chimeric infective particles expand species boundaries in phage-inducible chromosomal island mobilization Capsid-forming PICIs (cf-PICIs) produce their own capsids and exploit phage tails from unrelated species to transfer their DNA across bacterial hosts. This tail piracy enables broad dissemination and ...

Thrilled to share our two latest papers with the @tcostalab.bsky.social
lab! In the first, we uncover a new mechanism of satellite transfer: cf-PICIs hijack tails from diverse phages to spread across species.

Today, Professor Donal Wall, @uofglasgow.bsky.social attended a pitch session as part of the Science, Innovation and Technology Committee's 'Under the Microscope' inquiry to explain why they should be interested in microbiomes.

Let’s talk about/with/to phage!

I got hit by some rather sudden and extreme financial hardship so if anyone is in need of remote wetlab contract research, strictly BSL1, do let me know. Currently scrambling for gigs.

Microbial warfare brought us CRISPR. What big breakthroughs could be next? Gene editing and many other useful biotechnology tools came from studies of bacteria fighting off viral invaders. But scientists have only begun to unlock the secrets of this ancient arms race.
