DALLAS - Feb. 22, 2021 - Three decades-old antibiotics administered together can block a type of pain triggered by nerve damage in an animal model, UT Southwestern researchers report. The finding, published online today in
PNAS, could offer an alternative to opioid-based painkillers, addictive prescription medications that are responsible for an epidemic of abuse in the U.S.
Over 100 million Americans are affected by chronic pain, and a quarter of these experience pain on a daily basis, a burden that costs an estimated $600 billion in lost wages and medical expenses each year. For many of these patients - those with cancer, diabetes, or trauma, for example - their pain is neuropathic, meaning it s caused by damage to pain-sensing nerves.

DALLAS - Dec. 21, 2020 - A UT Southwestern research team has catalogued gene activity in the skeletal muscle of mice, comparing healthy animals to those carrying a genetic mutation that causes Duchenne muscular dystrophy (DMD) in humans. The findings, published online recently in
PNAS, could lead to new treatments for this devastating degenerative disease and insights into factors that affect muscle development.
