Cellular aging in immune cells signals early onset of cognitive depression

Blood tests measuring the aging of certain white blood cells can predict cognitive and mood-related symptoms of depression, rather than physical symptoms.

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.

Heavily processed foods may raise heart disease risk beyond poor nutrition alone

A 2026 review in Cardiology in Review reports that higher intake of ultra-processed foods is consistently associated with greater risks of cardiovascular disease, stroke, and cardiovascular mortality across cohort studies and meta-analyses. The paper also highlights plausible mechanisms involving gut dysbiosis, oxidative stress, and NF-κB-driven inflammation, with additives such as emulsifiers, preservatives, dyes, and sweeteners discussed as potential contributors.

Are socially isolated people more likely to develop cancer? Study of 350,000 adults explores the risk

A large UK Biobank study of more than 350,000 adults found that social isolation, but not loneliness alone, was associated with a modest increase in overall cancer risk during over 11 years of follow-up. The association was stronger in women and appeared partly linked to socioeconomic disadvantage, unhealthy behaviors, and inflammatory processes.

Hormone-driven immune cells may explain sex differences in chronic pain

Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.

Burn pit particles trigger lung inflammation through immune activation

A new study from National Jewish Health helps explain how exposure to burn pit smoke and desert dust may damage the lungs of military service members deployed to regions such as Afghanistan and Iraq.

Artificial lung keeps patient alive after lung removal

Researchers evaluate the effectiveness of a novel extracorporeal total artificial lung system to enable bilateral pneumonectomy in patients with severe ARDS.

Engineered liver tissue model mimics early metabolic liver disease

More than 100 million people in the United States suffer from metabolic dysfunction-associated steatotic liver disease (MASLD), characterized by a buildup of fat in the liver.

Bacteria repurpose viral injection systems to target diverse cells

New study shows how bacteria adapted a virus-derived injection system to recognize and attach to many different types of cells.

How DNA and life experiences leave distinct marks on the human immune system

Using single-cell epigenomic profiling of immune cells from 110 individuals, researchers show that genetic variation and environmental exposures shape the human immune system through distinct DNA methylation mechanisms. Genetic effects concentrate within gene bodies of memory cells, while environmental exposures primarily remodel regulatory regions in naive immune cells.

Chemotherapy-induced gut changes trigger anti-metastatic immune response

Chemotherapy commonly damages the intestinal lining, a well-known side effect. But this injury does not remain confined to the gut.

Study shows DHPS enzyme controls macrophage maturation across multiple organs

A new study led by researchers at the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health found that an enzyme involved in protein translation is essential for circulating immune cells, called monocytes, to mature into tissue-resident macrophages, a specialized population of immune cells that maintain organ health by clearing dead cells and debris.

Natural brakes on inflammation could treat chronic diseases

Researchers at University College London (UCL) have uncovered a key mechanism that helps the body switch off inflammation – a breakthrough that could lead to new treatments for chronic diseases affecting millions worldwide.

Natural daylight during office hours improves glucose stability in type 2 diabetes

Natural daylight exposure during office hours improves glucose control and boosts fat oxidation in individuals with type 2 diabetes, enhancing metabolic health.

Genetic and cellular mechanisms underlying steatotic liver disease

Steatotic liver disease (SLD), mainly encompassing metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), and metabolic dysfunction and ALD (MetALD), has emerged as the dominant cause of chronic liver disease worldwide, displacing viral hepatitis as the primary aetiology.

Investigating the impact of starting HIV drugs within days of infection

Despite effective HIV medication, the immune system of people with HIV remains disrupted in the long term. Researchers at Amsterdam UMC investigated whether this dysregulation can be prevented by starting HIV medication immediately after infection – i.e., within a few days.

Urolithin A recharges aging immune cells and boosts mitochondrial fitness in midlife adults

Urolithin A, a natural postbiotic known to trigger mitophagy, rejuvenated key immune cell functions in healthy middle-aged adults after 28 days. The trial showed a shift toward a youthful, energy-efficient CD8⁺ T-cell profile and enhanced bacterial clearance without inflammatory side effects.

Single-cell transcriptomics reveals new players in liver regeneration

The liver is remarkable for its ability to regenerate after injury, yet when this process fails, acute liver failure (ALF) carries devastating outcomes.

COVID-19 ages arteries prematurely with women most affected

COVID-19 may leave arteries biologically “older,” with women showing more persistent stiffness and symptom links than men. Findings from the large CARTESIAN cohort suggest this vascular aging effect is partly reversible over time.
