Researchers have identified a previously unknown population of neurons in the hypothalamus that play a critical role in ...

In the ARC, orexigenic neurons coexpress NPY and AgRP, whereas neurons coexpressing POMC and CART are anorexigenic. In the ARC, activation of AMPK leads to increased food intake, an effect that is ...

HFDs induce the expression of neuropeptide Y (NPY) and agouti-related protein (AgRP) in orexigenic neurons, while downregulating pro-opiomelanocortin (POMC) and cocaine- and a mphetamine-regulated ...

Mirror neurons received significant media attention in the 2000s and were painted by some scientists as the key to many of our advanced social abilities. However, many of the more significant ...

The best characterized pathways are the orexigenic neuropeptide Y/Agouti-related protein and the anorexigenic pro-opiomelanocortin/cocaine- and amphetamine-related transcript neurons in the ...

Not all brain cells are found in the brain. For example, a team at Caltech has identified two distinct types of neurons in the abdomens of mice that appear to control different aspects of digestion.

This month's cover highlights the article A novel bacterial effector protein mediates ER-LD membrane contacts to regulate host lipid droplets by Stacey D. Gilk, Rajendra Angara and Arif Sadi. The ...

"This is quite surprising since there are dozens of studies showing the actions of NPY in brain neurons that promote food intake—hence its designation as an appetite stimulant [orexigenic ...

Dec. 9, 2024 — A new study is helping solve the mystery as to why the brain shrinks in a unique pattern, known as atrophy, in chronic traumatic encephalopathy (CTE). This research provides novel ...
