Rodriguez Salazar, @caglaeroglu.bsky.social et al. @dukehealth.bsky.social show that Drp1-mediated mitochondrial fission is necessary for peripheral #astrocyte process formation. Loss of Drp1 induces astrocyte reactivity & disrupts cortical astrocyte organization rupress.org/jcb/article/...
@anbangdai.bsky.social et al. @pdc-lab.bsky.social report the localization of BLTP2 in different human cell types & reveal binding partners that mediate its tethering to the PM & to PM-connected structures including certain #endosomes & #macropinosomes undergoing fusion rupress.org/jcb/article/...
New paper alert! I’m very excited to share our paper published in @embojournal.org! @pdc-lab.bsky.social @yaleneuro.bsky.social
The Hanna lab is looking for an enthusiastic Research Technologist to join the team! 😊
You’ll help lead projects focused on organelle health & resilience to establish momentum in the lab. 🔬🥽

The outer membrane of Gram-negative bacteria blocks many antibiotics. Our latest work reveals that L-type pyocins bypass this barrier by inactivating the BAM complex, killing Pseudomonas aeruginosa without entering the cell, providing a new blueprint for beating antibiotic resistance.
New preprint: In situ Architecture of #Plasmodesmata.
Using #cryoET, #AlphaFold & proteomics, we uncover the native organization of plant intercellular nanopores.

"The bridge-like lipid transport protein VPS13C/PARK23 mediates ER–lysosome contacts following lysosome damage" out now in Nature Cell Biology

One for the Apicomplexa peeps:
ever wonder how does the IMC grow so fast during progeny formation? Where do all the lipids come from? In our latest work on malaria RBC stages we implicate this monster protein (~6000 residues!) and ER contact sites.
Happy+proud to share and keen to hear thoughts!
