The A–C linker structure!!! 🤩 Beautiful work. Even if you’re not as centriole-obsessed as we are, you’ll appreciate the elegance and complexity. Amazing to see U-ExM proteins in human centrioles fitting right into these densities. Congrats to all!
Huge congratulations to Wieczorek Lab PhD student Bin Cai and now-PI Jingwei Xu @xujwet.bsky.social on figuring out the surprisingly complex structure of the A-C linker crosslinking microtubule triplets in Tetrahymena basal body centrioles! www.science.org/doi/10.1126/...
Structure and assembly of the A-C linker connecting microtubule triplets in centrioles
Multiscale cryo-EM of centrioles reveals the structure and polymorphism of the A-C linker connecting microtubule triplets.

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?
Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵

I found these immune cells just finished mitosis but their midbody is still yet to be resolved. How cool? If you zoom in to the midbody, you can see its classical shape just like in the textbooks. I love these little details.

1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.

Lately I've been only posting images of really interesting protist here, but something that many don't know is that most of my time i'm expanding 'boring' mammalian cells and that I love human centrioles. Don't tell me that they are not beautiful😍👁️

It’s truly inspiring to see how persistence, collaboration, and communication across disciplines can transform ambitious ideas into such impactful stories. Seven years, four interdisciplinary teams, and countless discussions later—this really shows the power of timing, teamwork, and shared vision!😍
