A cancer therapy that prompts the body's immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart's largest blood vessels, a new study suggests.

Ketone bodies are not just about energy. These metabolites are powerful signaling molecules that have profound effects on the proteome and protein quality control in the brain. Scientists, working in mouse models of Alzheimer's disease and aging, and in the nematode C. elegans, reveal the ketone body -hydroxybutyrate interacts directly with misfolded proteins, altering their solubility and structure so they can be cleared from the brain through the process of autophagy. The work hints at a tantalizing possibility -- ketone bodies as a global treatment to restore the integrity of the proteome, addressing one of the key hallmarks of aging.
