NOX-1 identified as key molecular target to prolong ketamine's antidepressant effects

Treatment-resistant depression affects a large proportion of people with major depressive disorder, and while ketamine offers rapid relief, its antidepressant effects fade within a few weeks.

Parasites trigger a gut-to-brain signal that cuts food intake during infection

Researchers found that intestinal tuft cells signal to crypt enterochromaffin cells by releasing acetylcholine, triggering serotonin release and activating a gut-to-brain vagal pathway during type 2 inflammation. This sustained signalling, rather than the initial acute response, was linked to reduced food intake in mouse models of parasitic infection.

Study reveals immune changes in HIV and HCV coinfected patients

Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection leads to severe systemic inflammation, increasing non-AIDS morbidity and mortality risk. CD39 ectoenzyme on T-cells, which catalyzes the conversion of pro-inflammatory purines to immunosuppressive adenosine, plays an important role in inflammation control.

Drugs targeting TIE2 protein could help prevent formation of cerebral cavernous malformations

Researchers in the Perelman School of Medicine at the University of Pennsylvania have identified a cell surface receptor protein called TIE2 as the missing link between two key signaling pathways that drive the growth of blood vessel abnormalities known as cerebral cavernous malformations (CCMs).

Do multi-strain probiotics improve long covid symptoms?

Multi-strain probiotics show potential to modulate gut microbiome in long COVID, yet their impact on inflammation and recovery is not statistically significant.

Microtubules unveiled as active enzyme regulators

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling role. The findings, published in Science Advances, demonstrate that microtubules are in fact regulators of enzymatic reactions through reshaping the geometry of the enzyme's substrate proteins attached to them and controlling when key events occur to conduct cell division.

New pathway enhances brown fat thermogenesis and metabolic health

Researchers have determined how a key protein activates brown fat by expanding blood vessels and nerves in the heat-generating tissue.

Mediterranean diet may protect health through mitochondrial microproteins

A new study led by researchers at the USC Leonard Davis School of Gerontology suggests that the benefits of the Mediterranean diet may be driven, in part, by tiny proteins hidden within our mitochondria, opening a new window into how diet shapes aging and disease risk.

Snail-derived compound prevents clots while preserving normal bleeding

For more than a century, heparin has been the go-to anticoagulant to prevent harmful blood clots in blood vessels or the heart from forming or getting larger.

New nanoparticle therapy overcomes T cell exhaustion in solid tumors

Engineers at the University of Pennsylvania have developed a new type of lipid nanoparticle (LNP) that could one day serve as a universal immunotherapy for cancers that form solid tumors, including common variants such as cancers of the breast, liver and colon.

Scientists turn plastic waste into Parkinson’s drug levodopa using engineered bacteria

Researchers engineered a two-strain microbial system that converts PET-derived terephthalic acid into levodopa, overcoming key bottlenecks in transport and enzyme inhibition. The proof-of-concept process achieves high yields under mild conditions and demonstrates a potential route for upcycling plastic waste into valuable pharmaceuticals.

Activating hypoxia signaling improves metabolism and bone health

Obesity is widely known for increasing the risk of diabetes and cardiovascular disease, but its damaging effects on the skeleton are often overlooked. Excess body fat can disrupt bone metabolism, weaken bone quality, and impair fracture repair.

Study reveals dual role of PFK enzyme in metabolism and cell cycle progression

A metabolic enzyme studied for over seven decades has a hidden second function - it can unwind RNA and promote cell cycle progression, an additional function beyond its role in energy production, according to a new study led by the University of Surrey.
