In response, it condenses non-contractile, non-stretchable cortical rings to guide T cell's #amoeboid peristalsis in 3D ECM. science.org/doi/full/10.... 050
tabdanov.bsky.social @tabdanov.bsky.social · 18/08/2026BTW, the #nucleus in our #lymphocytes i.e., #T-cells is mostly a topological donut (torus), with #microtubules wrapped around its surface nicely. 010

The findings show that RhoA signaling—not myosin contractility—drives septin remodeling in interphase cells. www.molbiolcell.org/doi/10.1091/mbc… 051

Join tomorrow (Dec 17) to learn more about our efforts to understand how cells move in this physical state as well as how to manipulate the mechanics of HA. (B218; 1:30 pm) #cellbio2024 0133

When the world is going crazy, I find some peace watching at these myeloid cells (🔴) going about their day. They exist in tissue surrounded by other cells (🔵), and you can see them popping up and down, going in and out of plane as they explore their surrounding. 18320

Cyclic oscillations generate stride-wise migration, while modeling reveals that this behavior emerges from simple self-organization. www.biorxiv.org/content/10.6... 040

tabdanov.bsky.social @tabdanov.bsky.social · 19/01/2026Environments can induce cell structural instability, resulting in cell fragments shedding that can actively migrate, as described by as #Blebbisomes, or, as some decided to go more Hollywood with the terms, #Zombosomes. 050
