Cancer cells avoid an immune system attack after radiation by commandeering a cell signaling pathway that helps dying cells avoid triggering an immune response

Immunotherapy drugs that target a protein called programmed death ligand 1 (PD-L1) on the surface of cancer cells have quickly become a mainstay to treat many forms of cancer, often with dramatic results.

For decades, physicians have known that many kinds of cancer cells often spread first to lymph nodes before traveling to distant organs through the bloodstream.

When he was just 6 months old, Todd Roberts moved with his family from Houston to Brazil to support his scientist father’s research on malaria and other mosquito-borne diseases. There, he simultaneously learned Brazilian Portuguese and English, becoming the most fluent bilingual speaker in his household.

For decades, lung cancer has been one of medicine’s toughest opponents. Radiation therapy can slow the disease, but delivering curative doses without harming nearby organs, such as the heart and esophagus has remained out of reach.

Restricting calories has long been recognized as a powerful way to live longer, with periods of intermittent fasting proving more effective than a steady diet. However, the mechanism behind this phenomenon has been unclear.

Neurons in a part of the brain known as the ventromedial hypothalamus (VMH) appear to direct the body to boost endurance in response to exercise, a study co-led by researchers at UT Southwestern Medical Center shows.

Eating when the body is normally asleep appears to desynchronize the circadian clocks of different cell types in the intestines, a UT Southwestern Medical Center study suggests.

When activated in ovarian cancer cells, the receptor for the body’s primary stress hormone alters the tumor environment in ways that blunt immune response, according to new research led by UT Southwestern Medical Center.
