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.

Engulfment by brain macrophages in a short-lived vertebrate

This study introduces a genetic model in the short-lived African turquoise killifish to demonstrate that brain macrophages, particularly those resembling mammalian border-associated and monocyte-derived subsets, are responsible for clearing extracellular substrates but lose this engulfment capacity with age, offering a new platform for developing therapies against neurodegenerative diseases.

BAG2 Condensates Couple Proteostasis to CD8+T Cell Surveillance

The paper identifies a new class of BAG2-driven, phase-separated organelles called Immune-Protein Degradation Bodies (I-PDBs) that link protein quality control to adaptive immunity by redirecting aggregated proteins to specialized sites for degradation and antigenic peptide generation, a mechanism termed the Proteostasis-Associated Immune Relay (PAIR).

CD47 Blockade Reprograms the Monocyte-Macrophage Axis to Promote Inflammation Resolution in Atherosclerosis

CD47 blockade promotes the resolution of atherosclerosis by qualitatively reprogramming the myeloid landscape, specifically by suppressing inflammatory monocyte recruitment while simultaneously enriching macrophage subsets with enhanced efferocytic capacity to clear apoptotic cells.

Aquarius RNA helicase Protects Pluripotent Stem Cell Identity

The RNA helicase Aquarius (AQR) maintains pluripotent stem cell identity by safeguarding a resilient replication program that resolves transcription-replication conflicts and R-loops, thereby preventing transcriptional instability and the loss of cell identity.

Antarctic fish cell cultures show adaptation of organelle morphology and dynamics to extreme cold

By comparing cell cultures of the Antarctic plunderfish and a temperate shanny, researchers discovered that while basic subcellular organization and organelle dynamics are conserved in extreme cold, Antarctic fish exhibit specific morphological adaptations in lysosomes and mitochondria that may relate to their unique biological challenges.

A pcyt-1 Allelic Series Reveals In Vivo Consequences of Reduced Phosphatidylcholine Synthesis in C. elegans

By characterizing a series of *pcyt-1* mutant alleles in *C. elegans*, this study demonstrates that graded reductions in phosphatidylcholine synthesis trigger compensatory lipid remodeling toward long-chain polyunsaturated fatty acids and cause specific physiological vulnerabilities, particularly in the germline, without activating canonical cellular stress pathways.

Cellular senescence dysregulates antiviral interferon responses in idiopathic pulmonary fibrosis

This study demonstrates that the combination of cellular senescence and idiopathic pulmonary fibrosis (IPF) creates a dysfunctional antiviral state in lung fibroblasts, characterized by altered interferon responses and reduced reliance on key transcription factors like IRF3 and STAT1, which explains the heightened susceptibility of IPF patients to viral infections and acute exacerbations.
