New depression treatment targets the immune system instead of the brain

2 hours 13 minutes ago
A surprising new approach to depression treatment is showing early promise — not by targeting brain chemicals, but by calming the immune system. In a small clinical trial, researchers found that an anti-inflammatory drug normally used for rheumatoid arthritis appeared to ease symptoms in people with hard-to-treat depression, while also reducing fatigue and anxiety and improving quality of life.

New drug could finally stop deadly fatty liver disease

18 hours 6 minutes ago
Scientists at UC San Diego have unveiled a potentially game-changing treatment for MASH, a severe fatty liver disease affecting millions worldwide. The experimental drug, ION224, blocks a liver enzyme that drives fat buildup and inflammation, two key forces behind liver damage. In clinical trials, patients showed striking improvements in liver health, even without losing weight.

Popular anti-aging drug combo caused severe brain damage in mice

18 hours 33 minutes ago
A drug combo widely explored for anti-aging may actually damage the brain, according to new mouse research showing severe loss of myelin and changes linked to “chemo brain.” Surprisingly, the damaged cells resembled those seen in multiple sclerosis, giving scientists a new lead in understanding—and potentially repairing—the disease.

New laser heat treatment could stop blindness before it starts

19 hours 12 minutes ago
A new experimental treatment could finally offer hope for millions of people with dry age-related macular degeneration — one of the leading causes of blindness in older adults. Researchers at Aalto University discovered a way to gently heat tissue at the back of the eye using near-infrared light, triggering the cells’ natural “cleanup and repair” systems before major damage occurs.

Multicellular senescence impairs skeletal muscle recovery following disuse in aging

20 hours 56 minutes ago
Aged skeletal muscle has a diminished capacity to recover after disuse. Although muscle regrowth requires coordinated interactions between immune and progenitor cells, the mechanisms of impaired remodeling in aged skeletal muscle remain poorly understood yet possibly involve the accumulation of senescent cells. We used a flow cytometry approach coupled with scRNAseq to determine the muscle senescent cell identity and transcriptional landscape during skeletal muscle recovery following disuse...

TPM1 drives cytoskeleton-immunometabolism coupling and LGALS9/CD45-mediated neuroinflammatory propagation in retinitis pigmentosa

20 hours 56 minutes ago
Retinitis pigmentosa (RP), the most prevalent inherited retinal degeneration, features progressive photoreceptor loss with no approved disease-modifying therapies. While microglia-driven neuroinflammation accelerates RP progression, its sustaining mechanisms remain elusive. Through integrated multiomics profiling of retinal degeneration 10 (rd10) mice, we identify tropomyosin 1 (TPM1) as a previously unrecognized cytoskeletal-immune regulator orchestrating spatial neuroinflammation in RP....

Natural tissue immortality: Indefinite survival of sea cucumber explants

20 hours 56 minutes ago
Senescence and immortality are central biological paradigms. While regenerative capabilities in Deuterostomia are known, the fate of lost and discarded tissues has been presumed terminal. Here, we demonstrate that explanted epidermal, connective, neural, and muscle tissue from the sea cucumber Psolus fabricii (Holothuroidea: Echinodermata) healed and continued to grow in natural, nonaxenic seawater without supplementation for more than 3 years. In experimental trials, these explants, termed...

Aging modulatory effects of a decoction in Drosophila and C. elegans: mechanistic insights through NMR-based metabolomics

20 hours 56 minutes ago
As the challenges posed by an aging population become increasingly apparent, the prevention and treatment of age-related diseases have become key research priorities. This study hypothesizes that Zhizi Baipi Decoction exhibits aging modulatory effects. Traditional Chinese Medicine Decoction that has been passed down for generations and remains widely used in contemporary clinical practice. Due to their short lifespan, well-defined genetic backgrounds, and ease of manipulation, model organisms...

Respirometry-Based Screening of Marine Natural Products Identifies Leptochelin A as a Novel Modulator of Mitochondrial Function

20 hours 56 minutes ago
While mitochondria are recognized as promising therapeutic targets for common pathologies of aging, existing drug discovery platforms fail to capture the adequate physiological and biological contexts necessary to identify translatable, clinically-relevant leads. The goal of this study was to identify marine natural products that modulate mitochondrial function using a screening pipeline leveraging primary human cells in a cell-based phenotypic primary screen. Using this approach, we identified...

Decreases in the sustained firing capacity of layer 2/3 pyramidal neurons in the anterior cingulate cortex of aged rats

20 hours 56 minutes ago
The anterior cingulate cortex (ACC) is particularly vulnerable to aging, which impairs cognitive functions such as attention and working memory. Although aging is known to alter intrinsic electrophysiological properties in other brain regions, the differences in the properties of aged ACC neurons and young adult neurons remain uninvestigated. In this study, we compared the intrinsic membrane properties and firing characteristics of aged layer 2/3 pyramidal neurons (26-month-old rats) with those...

Scientists say guava juice could make iron supplements work better

23 hours 46 minutes ago
Researchers found that drinking guava juice may significantly improve anemia by helping the body absorb iron more efficiently. In a review of 17 studies, women and teenage girls who consumed guava juice — especially with iron supplements — experienced noticeable increases in hemoglobin levels. Since guava contains far more vitamin C than oranges, scientists believe it could become a simple, affordable nutrition tool in regions where anemia is widespread.
