Healthy blood vessels are not only important for heart health. Vascular well-being is critical for brain health and potentially for combating age-related cognitive decline and neurodegenerative diseases such as Alzheimer’s disease, according to a new study led by Penn State researchers. The findings point to a previously understudied but potentially crucial role that the brain’s […]

Discovery Could Help Reduce Unwanted Side Effects of Common Next-Generation Obesity Drugs
By separating the therapeutic benefits from the adverse effects of known obesity drugs, researchers at the Monell Chemical Senses Center found a population of neurons in the brain that controls food intake without causing nausea in animal models. The study, published in the journal Nature, describes two distinct neural circuits that control different effects of […]
Hepatitis B: “Sleep Timer” for Immune Cells Discovered
In chronic hepatitis B, the liver contains immune cells that could destroy cells infected with the hepatitis B virus, but are inactive. A team at the Technical University of Munich (TUM) has discovered that cells in the blood vessels of the liver set off a “sleep timer” that switches off the immune cells. An attack […]
Inflammation in Young Adulthood Has an Impact on Mental Health
Higher levels of inflammation in young adulthood are linked to lower performance on skills tests in midlife. Young adults with elevated levels of inflammation associated with obesity, physical inactivity, chronic disease, stress and smoking may have lower cognitive performance in midlife, a new UC San Francisco study shows. Researchers had previously linked higher levels of […]
