Cancer cells release a significantly more concentrated level of acid than previously known, forming an “acid wall” that could deter immune cells from attacking tumors, UT Southwestern Medical Center scientists show in a new study.

As they grow, solid tumors surround themselves with a thick, hard-to-penetrate wall of molecular defenses. Getting drugs past that barricade is notoriously difficult.

Less than three weeks after getting on an organ transplant list for HIV-positive patients, John Welch got the call. A liver was available from a deceased donor, and it was an excellent match.

UT Southwestern Medical Center is expanding its footprint to better serve the northwest Dallas region offering primary care visits ranging from management of chronic health issues to women’s health exams at UT Southwestern Medical Center at Coppell.

– A “clot-busting” drug recently approved to treat acute ischemic strokes (AIS) that can be delivered quickly works as well as a decades-old medication used by most hospitals in the U.S. and could hold significant advantages for some patients, a study led by a UT Southwestern Medical Center

An emotional overattachment to social media may be associated with increased severity of mental health symptoms among young people being treated for depression, anxiety, and suicidal thoughts, according to researchers at UT Southwestern Medical Center.

Weight-loss surgeries for adolescents increased 15% in the U.S. between 2021 and 2023, even as the Food and Drug Administration (FDA) approved effective new weight-loss medications for this age group, a study led by UT Southwestern Medical Center researchers shows. Their findings, published in The

Using a novel method that gives a readout of which proteins are in specific locations within cells, UT Southwestern Medical Center researchers have identified a protein that plays a key role in cell adhesion and movement.

An investigational therapy significantly shrank lung cancer tumors that are notoriously resistant to treatment by encouraging an attack from natural killer (NK) cells in an animal model, a study led by UT Southwestern Medical Center researchers shows.

Researchers at UT Southwestern Medical Center have linked blindness in animal models to a brain-wide cellular stress response that’s a common risk factor for dementia. Their findings, published in Nature Communications, could help explain the connection between vision or hearing loss and dementia.
