New study from our lab at NICHD, NIH! We identify TBC1D9 and TBC1D9B as novel ARL8 effectors that suppress exosome secretion by inactivating RAB11A and thus blocking exocyst-dependent fusion of multivesicular endosomes with the plasma membrane. www.pnas.org/doi/10.1073/...

Congratulations to @juanbonifacino.bsky.social at the NIH on his election to the American Academy of Arts and Sciences — one of the nation's most prestigious honorary societies — in recognition of his distinguished contributions to cellular and developmental biology! 🎉 www.amacad.org/new-members-...
New work from Niccolo Mencacci @feinberg.northwestern.edu et al., with contribution from @depaceraffa.bsky.social in our lab at the NIH, identifies pathogenic variants in BORCS5, encoding a subunit of the BORC complex, as a cause of a severe neurodevelopmental disorder. www.jci.org/articles/vie...
Take a look at our Research Highlight: Adriana Golding et al. www.nature.com/articles/s41... We highlight the work by Ghoochani et al., who generated an atlas of brain lysosomal proteins and identified SLC45A1-associated disease as a lysosomal disorder: www.cell.com/cell/fulltex...
Our first cancer biology preprint is up! TRIM9 switches melanoma cell phenotypes. First author @klukasik.bsky.social has taken the lab into new directions for sure in a fun collaboration with @coronin.bsky.social. We can't wait to hear what you think. www.biorxiv.org/content/10.6...

During #NeuronalDifferentiation, #organelles dramatically reorganize. #Microtubules are essential tracks for transport. But are they just highways, or can they instruct organelle behavior? Are tubulin modifications a regulatory code that guides organelle position or function? 1/9

It's such an honor to be featured in @jcb.org The Year in Cell Biology 2025 Collection!! 🤩 Huge thanks to my amazing PI @nanigrotjahn.bsky.social and my wonderful lab mate @nitishdua.bsky.social for bringing the hard copy of the magazine back from #cellbio1025 for me. It truly made my day! 🥰
What an honor to see @attychang.bsky.social’s work featured in @jcb.org The Year in Cell Biology 2025 collection! Even more special that it coincides with my first #cellbio2025 conference 🙂 s/o to co-authors @baradlab.com @hamid13r.bsky.social @zidlab.bsky.social #teamtomo #cellbio25
Attending #CellBio2025? Come see the Cohen Lab - Monday will be a busy day for us, including my theatrical debut in WICB "Scripts of Success" skits!
1/5: New preprint: Cytokines control the physical state of immune tissue. www.biorxiv.org/content/10.1... Unlike structured organs (heart, liver), immune tissue can shapeshift to form functional structures like germinal centers (GCs), tertiary lymphoid organs, granulomas, etc.
Cytokines control the physical state of immune tissue
Unlike most solid-like tissues, immune tissue is protean and reconfigurable—its component cells can patrol vast territories, find rare cellular partners, and dynamically self-organize into functional ...

I am super excited to share our article addressing a longstanding question in neurobiology: how Ca²⁺ signaling cascades initiated at dendritic spines operate at a distance. Check it out here: authors.elsevier.com/sd/article/S... @cp-cell.bsky.social.
Excited to be at #CellBio2024! Today, I'll be presenting my work exploring how the actin binding proteins and E3 ubiquitin ligases regulate neuronal morphogenesis. I'll be at poster board 40 and giving a teaser talk at 10:45 in Room 33B. Come say hi, if you love neurons, cytoskeleton or ubiquitin!
2024 Cell Biology of the Neuron GRC was rated one of the best Gordon conferences by attendees. Next stop is Italy (2026) chaired by @rkuruvi1.bsky.social & Gipi Schiavo. @barrlab.bsky.social and I will chair one after that. Attendance capped further, so don't miss it! www.grc.org/cell-biology...
