Cell biology is the study of life at its most fundamental unit: the cell. This field explores how these microscopic building blocks function, communicate, and replicate to sustain living organisms, from the simplest bacteria to complex human tissues. By understanding the machinery inside a cell, scientists unlock secrets about growth, disease, and the very nature of existence itself.

At Gist.Science, we track every new preprint uploaded to bioRxiv within this dynamic category. Our team processes each submission to provide both accessible plain-language explanations and detailed technical summaries, ensuring you can grasp complex discoveries without getting lost in dense jargon. Below are the latest papers in cell biology, offering a fresh look at the inner workings of life as they are shared with the world.

Microtubules sustain the fidelity of cellularization in a coenocytic relative of animals

This study demonstrates that in the animal relative *Sphaeroforma arctica*, microtubules work alongside actin networks to guide membrane furrows and ensure the faithful partitioning of nuclei and cytoplasm during cellularization, revealing conserved mechanistic parallels with canonical cytokinesis.

AP-3 and the V-ATPase Modulate CTP Synthase Assembly Through Spatial Association at the Yeast Vacuole

This study reveals that in yeast, the AP-3 adaptor complex and V-ATPase spatially associate with CTP synthase (Ura7) at the vacuole to coordinately regulate its assembly dynamics, where AP-3 promotes filament formation while restraining elongation, and V-ATPase inhibition triggers massive cytoophidia assembly in response to vacuolar function.

A closed-loop cell therapy engineered to autonomously secrete Activin A inhibitor protects from fibrodysplasia ossificans progressiva

This study demonstrates that a closed-loop cell therapy, engineered to autonomously secrete an Activin A inhibitor (ActR2A-Fc) in response to Activin A exposure via a BMP-responsive promoter, effectively prevents heterotopic bone formation in a mouse model of fibrodysplasia ossificans progressiva (FOP).

ATP8B1-TMEM30B Flippase Activity Maintains Stereocilia Lipid Asymmetry Required for Hearing

This study identifies the ATP8B1-TMEM30B flippase complex as essential for maintaining phosphatidylserine asymmetry in outer hair cell stereocilia, a process critical for hearing that is disrupted by TMC1/2 scramblase activity and whose failure leads to rapid hair cell degeneration and deafness.
