Immune proteins inside cells may drive human aging

This one's a swing and a miss for the garden: it's a deep dive into human immune biology and aging, with nothing about plants, soil, or anything you'd grow.
Scientists have found that a part of our immune system, called the complement system, doesn't just work outside cells fighting germs, it also works inside cells, where it seems to push cells toward aging faster. This review pulls together research on how that inside-the-cell activity contributes to problems in the aging brain, liver, eyes, kidneys, and other organs, and discusses potential drug strategies to target it.
Key Findings
Intracellular complement proteins C3 and C5 interact with core aging pathways including mTOR, NF-κB, and AMPK
Intracellular C3 dysregulation is linked to organ-specific aging effects across the brain, liver, eye, kidney, vasculature, lung, immune system, and cancer
Proposed therapeutic approaches include complement inhibitors, senolytics, RNA interference, and PROTACs, but compartment-specific tools and conditional knockout models are still lacking

This paper is about how a part of the human immune system works inside cells to speed up aging and age-related diseases like dementia and kidney failure. It's a biomedical review with no connection to plants, crops, or gardening.

Complosome as a key modulator of cellular senescence, aging and age-related diseases.
Aging is characterized by progressive physiological decline and accumulation of senescent cells that drive chronic "inflammaging" through the senescence-associated secretory phenotype (SASP). The c...

Condense to sense: a new path for plant osmosensing.
Understanding exactly how plants sense drought at the cellular level could lead to crops that survive water shortages better, helping secure food supplies as...
Cell biology is the branch of science that studies the structure, function, and behavior of cells — the fundamental units of all living organisms. In plant science, understanding cellular processes such as cell division, communication, and metabolism is essential for uncovering how plants grow,
