A common variation in a human gene that affects the brain’s reward processing circuit increases vulnerability to the rewarding effects of the main psychoactive ingredient of cannabis in adolescent females, but not males, according to preclinical research by Weill Cornell Medicine investigators. As adolescence represents a highly sensitive period of brain development with the highest risk for initiating cannabis use, these findings in mice have important implications for understanding the influence of genetics on cannabis dependence in humans.

Molecules that coordinate the development of highly specialized blood vessels in the kidney have been identified by investigators at Weill Cornell Medicine, University of Texas Southwestern Medical Center and Hofstra University. The findings pave the way toward new strategies for repairing damaged organs.
