Proteostasis News and Research

RSS

Each mammalian cell contains up to 20,000 proteins, all of which must be maintained and regulated. Proteostasis is a complex pathway that functions to maintain all of the proteins within and around a cell.

Bacterial protein fragment corisin found to drive pulmonary fibrosis

A bacterial protein fragment called corisin drives the process of pulmonary fibrosis by infiltrating and disrupting the cell's quality-control system, researchers at the University of Illinois Urbana-Champaign and Mie University in Japan found in a new study.

Hypoxia therapy shows promise for treating mitochondrial brain disorders

Oxygen isn't always a good thing. Of course, people-and most organisms-cannot live without it. But oxygen can also be quite toxic and lead to profound health consequences.

Single-dose gene therapy extends healthy lifespan in older mice

A research team from the Universitat Autònoma de Barcelona (UAB) has shown that a one-time administration of a gene therapy expressing the metabolic factor FGF21 can prolong health span in old mice.

Smoking triggers epigenetic damage linked to macular degeneration

Through a series of experiments supported by the National Institutes of Health, Johns Hopkins Medicine (JHM) researchers say they have advanced understanding of how smoking damages the eye and contributes to the development of age-related macular degeneration (AMD), the leading worldwide cause of visual impairment and blindness among people 50 and older.

Can GLP-1 drugs slow neurodegeneration? New review finds promising signals but limited clinical proof

This review examines how GLP-1 receptor agonists may influence neurodegenerative disease biology through metabolic, inflammatory, mitochondrial, and proteostasis pathways. Evidence from mechanistic, preclinical, and early clinical studies suggests potential neuroprotective effects, but definitive disease-modifying benefit remains unproven.

Research uncovers why certain brain cells are more resilient to tau protein buildup

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and related dementias, potentially leading to new targets for therapies or treatments.

Ageing slows brain protein clearance and shifts synaptic waste to microglia

Ageing slows neuronal protein degradation in mice, leading to widespread accumulation and aggregation of long-lived proteins, particularly at synapses. As neuronal clearance declines, microglia selectively accumulate synaptic proteins, suggesting a compensatory but potentially strained proteostasis pathway in the ageing brain.

Unfolding the role of Hsp70 chaperones in neurodegeneration

Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis (ALS) affect millions of people worldwide, yet treatments remain largely limited to symptom management.

Calcium signaling helps maintain protein quality in the endoplasmic reticulum

Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum (ER), a cellular organelle that synthesizes and transports proteins, is widely unknown.

New analysis reveals fundamental flaws in widely used measures of biological aging

A landmark review published today in Genomic Psychiatry challenges researchers to fundamentally reconsider how the field measures and conceptualizes biological aging.

Polyamines restore gut regeneration in aging mice

With aging, the intestine gradually loses its ability to regenerate after damage. An international research team involving the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) in Jena and the University of Turin has now found that polyamines, small molecules produced naturally in the body, can play a decisive role in this process.

Scientists uncover how brain enzyme OTULIN controls tau expression

Scientists have uncovered a surprising mechanism by which a brain enzyme called OTULIN controls the expression of tau, the protein that forms toxic tangles in Alzheimer's disease.

Study finds GLP-1 drugs improve strength and reverse aging biology in mice

Researchers showed that GLP-1 receptor agonism counteracts aging across multiple organs in mice, improving strength and reversing molecular aging signatures without meaningful effects on body weight. These benefits depended largely on hypothalamic GLP-1R signaling and closely mirrored the anti-aging patterns produced by rapamycin.

Global experts map out the practical steps that help extend life expectancy

The 1st World Longevity Summit in Kyotango, Japan brought together global experts to share advances in aging biology, lifestyle medicine, and community-based strategies for healthy longevity. Its joint declaration identified four pillars – social connection, plant-based diets, daily activity, and gratitude with purpose – as core foundations for extending healthy life expectancy worldwide.
