UT Southwestern Medical Center ranks among the top 25 hospitals nationally in eight specialties ranging from brain to heart to cancer care, according to the latest U.S. News & World Report’s annual Best Hospitals report.

Structural biology provides long-sought solution to innate immunity puzzle


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.

Researchers find immune component to rare neurodegenerative disease


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

In Memoriam: Dr. Jere Mitchell helped lay foundations of exercise physiology, changed medical practice on bed rest


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 scientists closing in on map of the mammalian immune system


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.

Cardio health decline tied to midlife wealth


A relative decline in wealth during midlife increases the likelihood of a cardiac event or heart disease after age 65 while an increase in wealth between ages 50 and 64 is associated with lower cardiovascular risk, according to a new study in JAMA Cardiology.

Lowering iron in fat cells prevented weight gain in mice


Lowering iron content in fat cells prevented mice fed a high-fat diet from gaining excess weight and developing associated health problems by limiting the amount of lipids absorbed by the intestines

Novel microscopy method at UT Southwestern provides look into future of cell biology


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