🥳 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.

Our latest T7SS study is now out in Science Advances!
We solved the cryoEM structure of the T7SSb core unit (T7bCU) composed of YukB, YukC, and YukD from Bacillus subtilis, revealing how these components assemble within the secretion machinery.

Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

#Phosphofructokinase (PFK) is considered an irreversible glycolytic #enzyme. This study shows that #Trypanosomes are the only known organism to use PFK in the gluconeogenic direction under normal conditions, likely due to its compartmentalization within glycosomes @plosbiology.org 🧪 plos.io/43r84Qc
