Chronic inflammation, which results when old age, stress or environmental toxins keep the body’s immune system in overdrive, can contribute to a variety of devastating diseases, from Alzheimer’s and Parkinson’s to diabetes and cancer.

The finding, which appears online Feb. 6 in the journal Cell Metabolism, could lead to new ways to halt or even reverse many of these age-related conditions.
