The innate immune system must detect viral RNA quickly, while avoiding overreaction to our own RNA. I am delighted to share our work, now published on-line in Molecular Cell: 5′-triphosphate guanosine RNAs recruit GTP-binding proteins to suppress RIG-I/IFN type I signalling.

A big shout out to the team, Dr Magdalena Wołczyk, Dr Ivan Trus and Jacek Szymański, for all the hard work that went into this achievement. Looking forward to keeping the momentum going and uncovering many more interesting avenues of RNA-protein interactions in innate immunity and beyond.

Not far away at HHMI. This is how we do it now @hhmi.bsky.social. HHMI Investigator reviews and all competitions consider pre-prints equivalent to peer-reviewed articles. No reason that this can't be the norm everywhere.

This is a lovely piece about the 2024 Nobel Prize to Victor Ambros and Gary Ruvkun, written by Bruce Wightman, the first author of one of the prize-winning papers. It emphasizes the importance of fundamental research and the beauty of heterochronic genes. #Celegans #devbio 🧪🧬 doi.org/10.1242/dmm....

It's about time: the heterochronic background for the 2024 Nobel Prize in Physiology or Medicine
Summary: The 2024 Nobel Prize in Physiology or Medicine has been awarded for the discovery of miRNAs; the groundwork was laid by investigating the timing of developmental events in nematodes.
