Happy to see the first paper from the lab published in the EMBO J today: link.springer.com/article/10.1...
In it, we reconstitute self-assembling cooperative oligomers of human Ndc80 and Ska kinetochore complexes that stabilise microtubule ends, and study these samples using cryoET and TIRF

The EMBO Workshop "#Centrosomes: From fundamentals to diseases" in #Lausanne, Switzerland, 1–4 September 2026 will highlight the advances in the field of centrosome #research. Register now!
Deadline: 1 June
https://meetings.embo.org/event/26-centrosomes
#EMBOCentrosomes #EMBOevents #conference 🧪
We must have been #ExtraNice this year- our #cilia & #centrosome 🧪 community- 🎅 Santa just dropped the 1st session of 2026 line-up @bscb-official.bsky.social @gensocuk.bsky.social @ukcilianetwork.bsky.social e-symposia- www.eventbrite.co.uk/e/bscb-genso... See you on the other side! Happy Holidays!
There are other things like making the last 5 years of all social media activity accessible through setting profiles public and providing handles. Including WhatsApp - would kill many ESTA applications - and including this thread 😬
Happy to share our fun team-up with @centriolelab.bsky.social & @stearnslab.bsky.social to reveal the architecture of the mammalian centriole’s Distal Ring 🛟. Very cool multiscale integration of #UExM 📏🔬with #CryoET ❄️🔬. Congrats to @ebertiaux.bsky.social & @computingcaitie.bsky.social #TeamTomo 🧪
🥳 Our new paper on C2CD3 is out in @plosbiology.org
With the labs of @cellarchlab.com , @chgenoud.bsky.social , and @stearnslab.bsky.social , we revealed the mammalian centriole Distal Ring architecture by combining #UExM and in situ #CryoET.
Big congrats to @ebertiaux.bsky.social and all involved.

Congratulations Dr. Fariña-Mosquera!!! A new doctor in the @luderslab.bsky.social!!! Big thanks to tribunal members Isabelle Vernos, Virginie Hamel @centriolelab.bsky.social , and Fernando Romero-Balestra!
You mean when only centromes are lost? Yes, because of the Golgi MTOC. The Rios lab paper actually showed it first, check Fig 7 - centrinone + AKAP450 KO destroys both centrosome and Golgi MTOC, and MTs become disorganized, clearly different from WT. www.embopress.org/doi/full/10....
This nice paper by Anna Akhmanova’s group does not address anchoring specifically, but organizing function. The problem is that if you remove centrioles, PCM still clusters or the Golgi takes over. If you prevent that (centrinone + AKAP450 KO) MT are completely disorganized. doi.org/10.7554/eLif...
Not saying motors, plus end regulators, MAPs don’t contribute. I believe some microtubules are anchored, but others are perhaps released - shown for the centrosome. Could be pulling by motors or loss of anchoring/nucleation without anchoring. Quite a knowledge gap here, I would say.
It does not only nucleate, it also anchors minus ends. This determines microtubule orientation (all minus ends at MTOC, all plus ends away from it). Because of this, modulating the shape and distribution of the MTOCs, also controls the overall shape of the network.
Doesn’t nucleation + anchoring of minus ends control microtubule orientation and, through shape and distribution of the MTOC, overall microtubule network shape and polarity? I agree it isn’t always the “center”, but I still think it has organizing activity.
What about their function in anchoring minus ends?
Congrats @araujolabub.bsky.social, make the flies breathe!
I see 6 fold symmetry and 9 fold asymmetry
Happy Halloween everyone! 🎃
Congratulations to the @estebanezlab.bsky.social lab and collaborators!!! A great story on the surprising repertoire of nuclear receptor oligomeric configurations and their regulatory roles.
Harder to focus on the science if it is poorly presented, I’d say.

FINALLY! Challenging to publish but we believe it is an important discovery: rdcu.be/eATFz

See? There's money! What would be great, instead, is to increase the budget for the existing schemes, though 🧪
"Super level" funding programs IMO are a huge waste of money - they benefit big labs at the cost of defunding others. We had big "Foundation grants" in Canada (albeit at a much smaller scale than similar programs in the USA/EU)... TL;DR it nearly ruined the sustainability of our research ecosystem

The #ESEB2025 meeting in Barcelona is getting closer, there are still places available but time for registration is running up. Are you going to miss the main evolutionary biology event in Europe this year?

Woah! Sick reconstitution work showing that MAP6d1 recruits tubulin to form B tubules on A tubule templates, and ALSO intra-luminal protofilaments, which apparently are present in neuronal microtubules.
So not only actin inside microtubules, but also additional tubulin protofilaments?!? Wild!
Check out this new 🔥work from Bryan Tsou’s lab - where does the information on how to assemble #centrioles with specific symmetry come from? Forget what you thought you knew about #centriole #biogenesis!!!
