A complex gene program initiates brain changes in response to cocaine

Drug Facts - Thu, 2020-07-09 15:28
Researchers used single-nucleus RNA sequencing to compare transcriptional responses to acute cocaine in 16 unique cell populations from the brain nucleus accumbens. The atlas is part of a major study that used multiple cutting-edge technologies to describe a dopamine-induced gene expression signature that regulates the brain's response to cocaine. The study shows neurobiological processes that control drug-related adaptations and reveals new information about how transcriptional mechanisms regulate activity-dependent processes within the central nervous system.

New molecule stops drug cravings in mice, with fewer side effects

Drug Facts - Thu, 2020-05-28 09:58
Researchers have developed a synthetic molecule that selectively controls the physiological rewards of cocaine in mice. It also may represent a new class of small-molecule drugs that are more specific and have fewer side effects. The molecule selectively activates beta-arrestin without activating the G protein, making its signal to the cell much more specific.

Health practitioners are constantly developing new ways to help those with drug and alcohol addictions wean themselves from their substance of choice. Most such programs have limited success, however. A new study finds that interventions that take a multidimensional approach -- tackling the biological, social, environmental and mental health obstacles to overcome while also addressing a person's substance use -- work best for those hoping to stop using drugs.

Early exposure to cannabis boosts young brains' sensitivity to cocaine, rodent study finds

Drug Facts - Mon, 2020-04-20 14:57
Cannabis use makes young brains more sensitive to the first exposure to cocaine, according to a new study on rodents. By monitoring the brains of both adolescent and adult rats after giving them synthetic psychoactive cannabinoids followed by cocaine, the research team identified key molecular and epigenetic changes that occurred in the brains of adolescents -- but not adults.
