Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

Check it out at PNAS today. Thank you Alexandre for the collaboration!!
PK Mem probes offer long time-lapse imaging of cell membrane dynamics. Made possible by
Jing Ling, Yitong Liu, and all the collaborators!

Thrilled to collaborate with @zhixingchen2.bsky.social Lab @pku1898.bsky.social !
We tested new PK Mem dyes—gentle, photostable tools to label the plasma membrane in live neurons, making it easier to track growth cone motility & axonal transport. #liveimaging #neuroscience

Target cell adhesion limits macrophage phagocytosis and promotes trogocytosis
Macrophages are presumed to attack antibody-opsonized cancer cells by phagocytosis. Rollins et al. found that macrophages attack adherent cells using trogo

🔬 In JCB's November issue: image shows a #macrophage nibbling a #cancer cell. The bone marrow–derived mouse macrophage is expressing a Chimeric Antigen Receptor (green) that activates the Fc Receptor signaling pathway in response to Her2. From Rollins et al. rupress.org/jcb/issue/22...

We have TWO papers out in @jcb.org this month! 🎉
First, @kirstin-rollins.bsky.social showed that macrophages nibble adherent target cells, like the ones found in solid tumors, instead of phagocytosing. Amazing movies from @sareenfiaz.bsky.social
