People who had a potentially allergic reaction to their first messenger RNA COVID-19 vaccination can safely receive their second shot, according to a study of patients conducted at several medical centers, including UT Southwestern.

Jere Mitchell, M.D., former director of the Harry S. Moss Heart Center at UT Southwestern Medical Center and an internationally recognized exercise physiologist whose seminal findings on maximal oxygen uptake changed conventional medical practice on bed rest and laid the foundation for central command physiology, died July 17. He was 92.

UT Southwestern researchers have identified an immune protein tied to the rare neurodegenerative condition known as Niemann-Pick disease type C.

UT Southwestern Medical Center ranked No. 3 in the nation on Forbes’ list of America’s Best Employers For New Graduates, placing it in the top 1 percent, and highest among academic medical centers.

An experimental drug that has shown promise in protecting healthy tissue from collateral damage caused by radiation therapy for cancer also appears to enhance radiation’s capacity to kill tumors.

Using artificial intelligence, UT Southwestern scientists have identified thousands of genetic mutations likely to affect the immune system in mice. The work is part of one Nobel laureate’s quest to find virtually all such variations in mammals.

What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality?

Mutations in a gene related to HER2, a gene frequently implicated in breast cancers and a variety of other malignancies, can amplify activity that spurs tumor growth

UT Southwestern researchers report the first structural confirmation that endogenous – or self-made – molecules can set off innate immunity in mammals via a pair of immune cell proteins called the TLR4-MD-2 receptor complex.

Jean D. Wilson, M.D., an internationally known endocrinologist whose scientific discoveries led to profound insights into the mechanisms underlying sexual differentiation and led to now widely used treatments for prostate disease, died June 13. He was 88.
