Protein complexes that play a critical role in launching an immune response assemble in droplets that form within the liquid environment in cells much like oil droplets in water, UT Southwestern scientists report in a new study.

State, regional, and business leaders joined researchers and students from UT Southwestern Medical Center and The University of Texas at Dallas for the dedication of the Texas Instruments Biomedical Engineering and Sciences Building that will accelerate training for the next generation and foster medical innovations to improve patient care.

UT Southwestern scientists have developed a new method to study the molecular characteristics of T cells, critical immune cells that recognize and attack invaders in the body such as viruses, bacteria, and cancer.

A team led by UT Southwestern researchers has identified a key gene necessary for cells to consume and destroy viruses. The findings, reported online today in Nature, could lead to ways to manipulate this process to improve the immune system’s ability to combat viral infections, such as those fueling the ongoing COVID-19 pandemic.

Being younger doesn’t protect against the dangers of COVID-19 if you are overweight, according to a new study from UT Southwestern.

Twenty-five years since its inception, the Dallas Heart Study (DHS) is recognized as one of the leading population-based studies of heart health in the U.S. It has spawned more than 230 research papers and produced major findings that have guided advancements in how cardiovascular disease, hypertension, and heart failure are treated.

Overweight and obesity patients without diabetes who switched GLP-1 receptor agonist (GLP-1RA) drugs were more likely to stick with their treatment longer than those who didn’t switch, according to a new study by UT Southwestern Medical Center researchers.

Researchers have identified factors associated with survival for patients initially diagnosed with metastatic breast cancer who were seen at UT Southwestern Medical Center and its affiliated sites.

Activating specific neurons in a part of the brain that serves as the body’s master circadian pacemaker caused mice to eat significantly more during a time of day when they would normally be at rest, a UT Southwestern Medical Center study shows.

A single, high dose of radiation delivered before other treatments could completely eradicate tumors in most women with early-stage, operable hormone-positive breast cancer, according to a study led by UT Southwestern Medical Center researchers.
