Scientists have discovered that some severe genetic disorders linked to rapid aging may be driven not just by damaged DNA, but by the body’s overreaction to that damage. When broken DNA fragments leak into the wrong part of a cell, an...
Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved...
Scientists have uncovered a natural braking system that helps the immune system switch off inflammation and prevent harmful immune cells from building up. Boosting this pathway in people reduced inflammation-related immune changes and...

UCLA researchers developed ready-made cancer-fighting T cells from cord blood stem cells that can attack solid tumors through two separate detection systems. In mice, a single dose controlled cancer and extended survival while avoiding a...
Scientists have found evidence that vulnerability to rheumatoid arthritis may begin before birth. Finger joints commonly affected by the disease develop with different tissue structures and larger populations of specialized fibroblasts...
Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs,...
Following nearly 10,000 older women for 10 years, researchers found that tea drinking was associated with slightly higher hip bone density. Moderate coffee consumption did not appear harmful, but drinking more than five cups a day was...
CAR T-cell therapy dramatically reduced disease activity in six people with severe rheumatoid arthritis that had resisted other treatments, with three achieving medication-free remission. The treatment may work by clearing out harmful...
Older adults who received the Shingrix shingles vaccine were 24% less likely to be diagnosed with dementia over four years in a study of more than 500,000 people. Researchers estimate the difference could amount to roughly one dementia...
Researchers have found a way to supercharge natural killer cells, powerful immune cells that can attack cancer, so they can penetrate solid tumors and keep fighting once inside. In mice, these specially prepared tissue-resident cells...
People who reach 110 and beyond appear to have unusually large numbers of rare immune cells capable of killing abnormal cells. These CD4 cytotoxic T cells became more common with age and often expanded into large groups of nearly...
Backyard bird feeders could become unexpected hotspots for H5N1 as Australia’s bird flu outbreak spreads, bringing species together in ways that rarely occur naturally. Experts say stopping feeding is safest, while smaller amounts of...
A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found that GDF15 activates a previously...
AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness” that helped distinguish strong...
A compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation—it could leave a lasting protective “memory” in the gut. Northwestern Medicine researchers found that butyrate can reprogram intestinal...
More than 1,000 genetic switches behave differently in male and female immune cells, helping explain why women are much more vulnerable to autoimmune diseases such as lupus. Female immune systems appear genetically tuned for stronger...
Orange juice may have a much bigger effect on the body than scientists once realized. Drinking it regularly appears to influence genes tied to inflammation, blood pressure, metabolism, and blood sugar control, while studies have also...
A specially engineered chewing gum reduced HPV by up to 93% and nearly eliminated two bacteria linked to head and neck cancer. The treatment preserved beneficial mouth bacteria, raising hopes for a safer and more affordable therapy.
A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of white blood cell circulating in the bloodstream,...
A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the...
For most adults, a daily caffeine habit may be safer for the heart than many people assume. A new American Heart Association review found that up to 400 milligrams of caffeine a day, roughly three to five cups of regular black coffee, is...
Scientists uncovered how influenza A commandeers human cells, including a surprising strategy that dissolves tiny structures in the nucleus and releases proteins the virus may use to reproduce. The detailed molecular map could reveal new...
A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination. In a small pilot trial, researchers gave spermidine supplements to adults...
An experimental drug called DT-109 reversed severe fatty liver disease in animal studies by repairing the gut and preventing harmful toxins from damaging the liver. The discovery could open the door to a new class of treatments for MASH...
A new study found that dietary fiber can determine whether beneficial intestinal worms help reduce inflammation or become essentially inactive. With plenty of fiber, the worms remained healthy and supported an anti-inflammatory response,...
Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The discovery could lead to more effective...
Scientists have discovered that creatine may strengthen one of the immune system's most important cancer-fighting pathways by energizing dendritic cells that activate killer T cells. The promising results could eventually help make...
A new intranasal DNA vaccine may give the immune system an extra weapon against tuberculosis by targeting bacteria that can hide from antibiotics. In animal studies, it helped clear infections faster, reduced lung inflammation, and...
Scientists found that one tiny genetic change can completely alter how a coronavirus behaves in different species. Comparing SARS-CoV-2 with a closely related bat-only virus, they showed that a single amino-acid difference affects...
Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it. Green and oolong tea kombuchas emerged as the most biologically active, while fermentation...
Researchers uncovered why H5N1 bird flu attacks cows’ udders instead of their lungs: the virus’s preferred receptors are concentrated in mammary tissue. The breakthrough could help scientists predict future bird flu jumps and spot...
A low-calorie fasting-style diet significantly reduced inflammation linked to gum disease in a small clinical study. The findings suggest that what people eat may influence gum health almost as much as what they do with a toothbrush.
Tea may help protect against heart disease, diabetes, cancer, cognitive decline, and age related muscle loss, according to a major review. But the way you drink it matters, since bottled and bubble teas often contain ingredients that can...
Scientists have uncovered a hidden immune system "brake" that may help cancers avoid being destroyed. The molecule, called SLAMF6, weakens the body's cancer-fighting T cells and can leave them exhausted over time. Researchers developed...
A major long-term study of more than 54,000 adults found that where nitrate comes from may matter far more than how much you consume. People who got more nitrate from vegetables—roughly the amount in a cup of baby spinach a day—had a...
Scientists have successfully tested an AI-designed universal coronavirus vaccine in humans for the first time, finding it to be safe and well tolerated. The vaccine generated immune responses against multiple coronaviruses, including...
