Today in Nature @nature.com, we report a new approach to studying human brain development and modeling disease in vivo. Open article link below 👇
Millions of beating cilia keep airways clean. At the base of each is the transition zone (TZ), a gate that controls which proteins enter and leave. In our paper out today in Science, we used cryo-FIB-ET to image the TZ inside human airway cells www.science.org/doi/10.1126/...
In situ structure of the human ciliary transition zone links linker defects to primary ciliary dyskinesia
The ciliary transition zone (TZ) regulates ciliary proteome composition, yet its molecular architecture, protein content, and contribution to motile ciliopathies remain poorly defined. We applied in situ cryo-electron tomography and subtomogram averaging ...
