Children born to mothers who consume a high-fat, high-sugar diet during pregnancy and breastfeeding face a higher risk of developing fatty liver disease later in life.

UF Health Cancer Institute researchers have discovered a small compound produced naturally by gut bacteria that doubled the response to lung cancer immunotherapy treatment in mice and can now be made into a drug for testing in humans.

Scientists have identified a promising target for treatment of a devasting autoimmune disease affecting the brain.

Pregnant individuals with inflammatory bowel disease (IBD) have higher levels of pro-inflammatory immune molecules, known as cytokines, in their vaginal mucosa than their healthy counterparts, according to a new study published January 14, 2026 in the open-access journal PLOS One by Ana Maldonado-Contreras of University of Massachusetts Chan Medical School, U.S., and colleagues.

Using participant skin cells reprogrammed into neurons, Weill Cornell Medicine researchers have identified genetic signatures associated with HIV infection that may contribute to the cognitive impairment that often occurs in people living with HIV, even when the virus is controlled.

Autoimmune diseases such as multiple sclerosis arise when the immune system turns against the body itself.

Researchers have identified bradycardia-an abnormally low heart rate–as a symptom of xylazine-opioid overdose.

Dealing with an infection isn't as straightforward as simply killing the pathogen. The body also needs to carefully steer and monitor its immune response to prevent collateral damage.

A toxin secreted by cholera bacteria can inhibit the growth of colorectal cancer without causing any measurable damage to the body. This is shown by a new study by researchers at Umeå University, Sweden.

Exposure to per- and polyfluoroalkyl substances (PFAS), a class of highly persistent environmental chemicals commonly referred to as "forever chemicals," is associated with a higher risk of gestational diabetes mellitus and altered markers of insulin resistance and insulin secretion, according to a new systematic review and meta-analysis led by researchers at the Icahn School of Medicine at Mount Sinai.

A team led by investigators at the Mass General Brigham Cancer Institute has discovered that a particular marker on tumor cells circulating in the blood indicates whether a patient with lung cancer will experience a lasting response to a newly approved immunotherapy called tarlatamab.
