Discovery of protein function opens door to potential therapies for addiction, behavioral disorders

The human brain consists of several intricate networks or "circuits." One such complex circuit, called the "reward circuit," is involved in reward-associated learning, a process in which nerve cell activity changes in response to a "reward" stimulus (something that the brain perceives as a reward).

New database helps identify therapeutic targets to fight infectious diseases

Infectious diseases are caused by pathogenic microorganisms capable of entering, colonizing and growing within a host organism, thus producing an infection. Bacterial infections have been on the rise worldwide in recent years, but many mechanisms underlying bacterial pathogenesis are still poorly understood.
