Research Overview

The ultimate goals of Joseph Majzoub's work are to understand how various stresses affect health.

The specific aims of the Majzoub laboratory's studies are to analyze beneficial and detrimental effects, and the regulation of, the mammalian stress response, particularly within the brain. Current research focuses on the behavioral and neuroendocrine roles of corticotropin-releasing hormone (CRH), the regulation of CRH gene transcription by silencing factors, and the role of Mrap2 to modulate energy balance during stress, both in the fetus and postnatally.
