Researchers discover a molecular signature to flag dysfunctional aging cells

UCLA researchers have identified a rogue population of immune cells that quietly accumulates in aging tissues and in the livers of people with fatty liver disease. Clearing these cells, they found, dramatically reduced inflammation and reversed liver damage in mice - even while the animals remained on an unhealthy diet.

Researchers discover how stress signals weaken the aging immune system

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their effectiveness. Normally, HSCs can both self-renew and generate a balanced mix of blood cells, but over time they produce fewer new cells, favor certain cells such as myeloid cells over lymphoid cells, and struggle to support a robust immune response.

Gut-liver changes drive foodborne infection severity in fatty liver disease

A research team led by the University of California, Irvine's Joe C. Wen School of Population & Public Health has uncovered a critical biological link explaining why individuals with metabolic dysfunction–associated steatotic liver disease (MASLD), or fatty liver disease, face significantly worse outcomes from certain foodborne infections.

Matching exercise timing to body clock chronotype improves heart health

Timing exercise to match body clock chronotype-the natural predisposition to morning or evening alertness-may lower cardiovascular disease risk among those who are already vulnerable, suggests research published in the open access journal Open Heart.

Semaglutide improves liver function independently of weight loss

Researchers at Toronto's Sinai Health have found that semaglutide – the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1 – acts directly on a subset of liver cells to improve organ function and does so independently of weight loss.

Waist-to-height ratio outperforms BMI in predicting hypertension risk

New waist-to-height cut-offs to assess fat mass and obesity predicted the risk of hypertension better than body mass index, according to a new study from the University of Eastern Finland and the Robert Wood Johnson Medical School at Rutgers University in the US.

Study finds long COVID leaves a distinct immune signature in the blood

Researchers identified a small panel of inflammatory and neurology-related blood proteins that may help distinguish long COVID from recovery or no prior infection, while also showing that booster vaccination did not appear to worsen these protein responses in this cohort. The study also found that immune responses after reinfection differed from those seen after the first SARS-CoV-2 infection, suggesting altered long-term immune behavior in some previously infected individuals.

Very high prenatal PFAS exposure increases childhood asthma risk

High prenatal exposure to PFAS linked to increased childhood asthma risk, highlighting concerns over 'forever chemicals' and early-life environmental impacts.

Microplastics lab studies may fail to reflect real-world exposure

Microplastics pose health risks, but lab studies often fail to reflect real-world exposure, highlighting critical gaps in toxicological research methodologies.

Beetroot supplement raises nitric oxide markers in triathletes after one week

A randomized cross-over pilot study in 10 amateur male triathletes found that a beetroot-based multi-ingredient nitrate supplement increased nitric oxide-related and redox biomarkers over 7 days without evidence of lipid oxidative damage. The supplement was generally well tolerated, but the study did not measure whether these biochemical changes improved performance or recovery.

Parents’ intake of sugar substitutes may influence offspring gut biology, study finds

A mouse study in Frontiers in Nutrition found that parental sucralose and stevia intake altered gut microbiota, short-chain fatty acids, and gene expression across generations, with sucralose showing the stronger and more persistent effects. The changes were transmitted to offspring not directly exposed to the sweeteners, although several effects were attenuated by the F2 generation.

Targeting super-enhancer mechanisms offers new strategies for cancer therapy

Super-enhancers (SEs) are large clusters of transcriptional regulatory elements that drive oncogene expression, maintain malignancy, and create "transcriptional addiction" in cancer.

Study explains why vaccines underperform in people living with obesity

New findings reveal that obesity significantly impaired the quality and longevity of antibody responses to a Pseudomonas aeruginosa vaccine in a mouse model.

Targeting senescent fat cells provides new hope for ovarian cancer

Ovarian cancer is the most lethal malignancy of the female reproductive system. Due to its insidious early symptoms and the absence of specific screening modalities, approximately 70% of patients are diagnosed at an advanced stage.

Obesity health risks differ significantly between men and women

New research being presented at this year's European Congress on Obesity (ECO) in Istanbul, Turkey (12-15 May), reveals distinct patterns of heart, metabolic, and inflammatory health risks between men and women living with obesity, providing an insight into how clinicians may be able to tailor management approaches.

Natural peptide PEPITEM shows promise in reducing arthritic joint swelling

Scientists investigating the naturally occurring immunopeptide PEPITEM have shown reductions in arthritic joint swelling to a degree comparable to the current standard of care, and reduce the inflammatory changes that cause joint damage.
