Well, really happy to see that finally evidence showing VCP ruptures depolarised mitochondria outer membrane, as we have seen that VCP can also extract bacterial surface proteins and rupture cytosolic dwelling pathogens also.

Congratulations! Fantastic findings. Do you also find the hierarchical recruitment of GBP2-4 in these structures?

📢A new effector-triggered immunity role for GBP1! No place for pathogens to hide now that GBP1 can detect extracellular pathogens that hijack the actin cytoskeleton. Surprise*suprise* GBP1 does this independently of LPS! 🧵

So grateful to the AIC team at Janelia! Three surreal weeks packed with months of learning, cutting-edge technology, and inspiring science. Huge thanks to Bob’s for the amazing food—it made everything even sweeter. Truly an experience of a lifetime that I’ll always cherish! 💛

Incredibly honoured and grateful to receive the 2025 Angelika Amon Young Scientist Award! Deep thanks to my supervisor @anirban-banerjee.bsky.social, friends, lab colleagues, Department of Biosciences and Bioengineering, and @iitbombay.bsky.social for their unwavering support. Simply Lovely.

So cool. Congratulations. Maybe after ubiquitination, AR will be pulled out from the chromatin, or it can fall off spontaneously.

NLRP3 inflammasomes can assemble on most organelles. A beautiful study by Hafner et al demonstrate the flexibility of organelles that can support inflammasome activation. Kudos to the authors on an intriguing study.

Tick Tock Neutrophil Clock

Hall Lab (Auckland) with zebrafish model find light boosts the circadian protein Per2, which enhances ROS and hmgb1a expression via a BMAL1–NF-κB enhancer

End result: Better bacterial clearance and survival—a circadian clock-gated boost for daytime innate immune function

Cool insights.

If you're into host-pathogen interactions and cell-autonomous immunity, this is a must-attend! Stellar speaker lineup and exciting science all around. Also, catch work from our lab being presented!"

Haven’t shared this in a while. But the #ubiquitin and #ubl Starter Pack now includes 116 profiles to follow if you’re interested in the field: signalling, structure and biochemistry, biology, mechanisms, proteostasis, TPD, chemical biology… Check out the list and let me know if you are missing.

Great to see this out. A story that spanned continents, cities and budget codes…

Big thanks to all the teams involved!

Congratulations! So many ways we can sense threats, a detailed and layered system.

How do intracellular #bacteria breach vacuoles to enter the host cytosol? @leaswistak.bsky.social @matthijnvos.bsky.social @enningalab.bsky.social &co show that #Shigella uses its T3SS system to damage endomembranes via mechanoporation to initiate cytosolic access @plosbiology.org 🧪 plos.io/4jXrr9Z

Super happy to share that our work on the specific inhibition of USP30 - a clinical stage Parkinson's drug target - is now online at NSMB www.nature.com/articles/s41... Have a read if you fancy chimeric protein engineering or a framework for DUB ligandability. Huge congratulations to Nafizul & team!

Amazing work, congratulations.

We can see our ECR-focused LINE symposium already on the horizon (9th of June) @crick.ac.uk. shorturl.at/MyWNl 🥳
You can submit your abstracts (talk or poster) until the EXTENDED DEADLINE on the 12th of May here: shorturl.at/7KuXL
Free registration shorturl.at/wLyWY
We're excited to see you there!

Congratulations. How amazing this battle is turning out to be, between host and pathogens.

RNF213, a host E3 ligase, ubiquitylates LPS to mark cytosol-invading bacteria for autophagy. But how do cytosol-adapted bacteria escape? We found that Shigella's E3 ligase IpaH1.4 blocks LPS ubiquitylation by degrading RNF213 via the proteasome.

Amazing analogy. Thank you for sharing.

🚨Got a few minutes over breakfast? 🥣
Here’s a quick peek at what we’ve been up to.
If you don’t have time for the full paper, this summary’s got the essence.
Hope you find it as exciting! 🦠🔬 @natmicrobiol.nature.com @springernature.com

Happy to share my Ph.D work!!
Our latest paper shows VCP/p97 uses its tweezer-like action to tear invading bacteria apart — a powerful cellular defense! 🦠
