University of Maryland School of Medicine and University of Vermont researchers have shown how the brain communicates to blood vessels when in need of energy, and how these blood vessels respond by relaxing or constricting to direct blood flow to specific brain regions.
DALLAS – June 28, 2021 – Lowering iron content in fat cells prevented mice fed a high-fat diet from gaining excess weight and developing associated health problems by limiting the amount of lipids absorbed by the intestines, UT Southwestern scientists report in a new study. The findings, published online in Cell Metabolism, could eventually lead to new strategies to protect people against obesity and related diseases.

The study demonstrates how dopamine rises rapidly in mice moved from a simple recording chamber to their home cage, but less so when they return to a cage not quite like the one they knew.
