Blocking xenophagocytosis improves donor cell survival and interspecies organ generation

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, report researchers at Institute of Science Tokyo, Japan.

Researchers uncover hierarchical sensory processing system in the zebrafish brain

How does the brain make sense of what we see, hear, and feel—and transform these separate signals into a coherent perception of the world?

Ketamine boosts neuroplasticity through microglia in female brains

Doctors use ketamine on patients as general anesthesia before surgery. They also prescribe it in low doses for pain management, and more recently, it's been used for treatment-resistant depression where other drugs have failed.

Engineered extracellular vesicles counter deadly cytokine storms in mice

The COVID-19 pandemic highlighted some severe consequences of unchecked respiratory disease, including cytokine storm.

TRF2 protein preserves muscle stem cell identity and regeneration

A protein best known for protecting the ends of chromosomes also helps muscle stem cells preserve their identity and repair damaged tissue, according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania.

Immune cell navigation breakthrough offers hope for better anti-inflammatory drugs

A scientific collaboration between the University of Bath (UK) and the UMass Chan Medical School (USA) have determined how a specific type of white blood cells, called neutrophils, move through the body.

Brain immune cells drive recovery from ketamine anesthesia in females

During ketamine anesthesia, the brain's nerve cells fall silent-as consciousness returns, they begin to reconnect.

New mechanism linked to septic heart injury protection uncovered

Sepsis triggers widespread inflammation, circulatory failure and metabolic stress, and cardiac dysfunction is a common complication associated with sharply poorer outcomes.

Consuming less protein could have greater health benefits and extend lifespan

Protein-fortified foods are popping up everywhere, from cereal and coffee to even protein water. But a new review covering over 350 papers on protein restriction and aging-publishing July 31 in the Cell Press journal Cell Press Blue-suggests that consuming less protein could have greater health benefits and could, in some cases, extend lifespan.

Scientists map protective cell networks hiding dormant breast tumor cells

Researchers at the MRC Laboratory of Medical Sciences (LMS), Imperial College London and UCL Genetics Institute have created a detailed map of cells within breast tumors and identified distinct neighborhoods of proliferating and dormant cells.

Soy lysolecithin reduces salt-induced hypertension and cognitive decline

High salt (HS) intake is a major global health concern, closely linked to hypertension and growing evidence of cognitive and emotional decline.

Mouse study links leaky gut to severe food allergies

A "leaky gut" might increase the severity of food allergies, according to new research conducted in mice and published in The Journal of Immunology.

New stem cell vesicles accelerate diabetic wound healing

Diabetic foot ulcers are among the most serious complications of diabetes because prolonged inflammation, poor circulation, and defective angiogenesis can leave wounds open for months and increase the risk of infection and amputation.

How intensive poultry farming accelerated the evolution of Campylobacter

Intensive poultry farming transforms Campylobacter jejuni ecology, enhancing host adaptability and raising concerns for foodborne illness transmission.

Tea, tap water and child IQ: What a Canadian pregnancy study found

Researchers analyzed 485 mother-child pairs in Canada to examine whether estimated fluoride intake from tea during pregnancy was associated with IQ at ages 3 to 4. Each 0.5 mg/day increase was associated with a 2.24-point lower full-scale IQ score, although the observational design and estimated exposure prevent causal conclusions.

Hydrogen-powered shipping could deliver $284 billion in annual health benefits

Researchers modeled how replacing conventional global shipping fuels with hydrogen could change PM2.5 and ozone pollution, premature mortality, and monetized health benefits. Under complete transition, the model estimated 129,458 fewer premature deaths and US$284 billion in annual monetized health benefits, although some regions experienced increased pollution from hydrogen production or altered ozone chemistry.

Research identifies common neuroimmune signatures in rapid-acting antidepressants

In a new study, researchers from The University of Texas MD Anderson Cancer Center have uncovered insights that may help explain how rapid-acting antidepressants, such as ketamine and psychedelics, can reduce symptoms in difficult-to-treat depression.

NIH funds UVA research to develop advanced laboratory tissue models

A University of Virginia researcher has received a five-year, $2.1 million National Institutes of Health grant to develop advanced laboratory tissue models that could improve drug testing, deepen scientists' understanding of disease and reduce the need for animal testing.

Insilico unveils standardized evaluation framework to validate AI-driven drug discovery models

As general-purpose and domain-specific AI models rapidly infiltrate drug discovery, one critical question looms over the pharmaceutical sector: Can these models actually discover drugs, or are they just good at taking tests?

Pork supply chains may be shaping the global spread of drug-resistant Salmonella

Researchers linked 129,136 global human and swine Salmonella genomes with sampling from a Guangdong pork supply chain to examine how downstream stages relate to antimicrobial resistance. The study suggests slaughterhouse and retail interfaces may concentrate S. 4,[5],12:i:- ST34, resistant strains, and mobile resistance elements, supporting broader One Health surveillance beyond farms.
