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.

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.

Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means.

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.

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

An international team of cancer researchers has identified important mechanisms that activate antitumor immune response during radiation therapy

While the amazing regenerative power of the liver has been known since ancient times, the cells responsible for maintaining and replenishing the liver have remained a mystery.

Increasing a protein concentrated in brown fat appears to lower blood sugar, promote insulin sensitivity, and protect against fatty liver disease by remodeling white fat to a healthier state.

Imaging at near-atomic resolution of a key immune protein commonly known as STING has revealed a previously unrecognized binding site that appears to be pivotal for launching immune attacks, UT Southwestern scientists report in a new study.

UT Southwestern researchers have discovered a mechanism that cells use to degrade microRNAs (miRNAs), genetic molecules that regulate the amounts of proteins in cells.
