Protein linked to learning induces cocaine addiction, say researchers

A team of researchers says it has solved the longstanding puzzle of why a key protein linked to learning is also needed to become addicted to cocaine. Results of the study, published in the Aug. 1 issue of the journal Cell, describe how the learning-related protein works with other proteins to forge new pathways in the brain in response to a drug-induced rush of the “pleasure” molecule dopamine.

Junk-food diet during pregnancy may change development of opioid pathway in baby's brain

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that eating a junk-food diet during pregnancy changes the development of the opioid signalling pathway in the baby's brain and permanently alters the way this system operates after birth.

Study supports topiramate as promising medication to treat addiction

The drug topiramate, typically used to treat epilepsy and more recently weight loss, may also help people addicted to both cocaine and alcohol use less cocaine, particularly heavy users, researchers in the department of Psychiatry at Penn Medicine report in a new study published in Drug and Alcohol Dependence.

TSRI scientists study 3-D structure of glucagon receptor for treatment of diabetes

The study is reported on July 17, 2013, in an advance online edition of the journal Nature, alongside a British laboratory's structural study of another member of the same class of receptors-known as "class B" G protein-coupled receptors (GPCRs).

Long-term cannabis use, dopamine and motivation: an interview with Dr Michael Bloomfield, Department of Medicine at Imperial

We classified ‘long-term’ cannabis use as being regular, at least weekly, cannabis use for over 12 months. This is the period of time that’s used in the DSM-IV psychiatric diagnostic manual to classify substance use disorders. In our study the average duration of at least weekly use was just over four and a half years.

USC study shows missing brain protein may be responsible for severe over-worry and fear

A little bit of learned fear is a good thing, keeping us from making risky, stupid decisions or falling over and over again into the same trap. But new research from neuroscientists and molecular biologists at USC shows that a missing brain protein may be the culprit in cases of severe over-worry, where the fear perseveres even when there's nothing of which to be afraid.

Coffee and appetite: an interview with Matt Schubert and Associate Professor Ben Desbrow, Griffith University

We wanted to do something a bit different than the “typical” work on caffeine and exercise, and I have considerable interest in appetite regulation, so we built up from there.

Researchers confirm that bath salts could be more addictive than methamphetamine

Scientists at The Scripps Research Institute (TSRI) have published one of the first laboratory studies of MDPV, an emerging recreational drug that has been sold as "bath salts." The TSRI researchers confirmed the drug's powerful stimulant effects in rats and found evidence that it could be more addictive than methamphetamine, one of the most addictive substances to date.

Cannabis users appear to lack motivation

Researchers found that dopamine levels in a part of the brain called the striatum were lower in people who smoke more cannabis and those who began taking the drug at a younger age.

Researchers find new treatment option for schizophrenia

A research group led by professor Jesper Ekelund showed that by giving a very large dose of famotidine (200 mg daily), sufficient amounts of the drug are able to penetrate the so-called blood-brain barrier to affect the histamine system in the brain.

Study: Pluripotent stem cell line-derived neurons survive and respond to cues in the primate brain

A team of researchers from Rush University, Yale University, the University of Colorado and the St. Kitts Biomedical Research Foundation transplanted human embryonic stem cells into primate laboratory animals modeled with Parkinson's disease and found "robust survival" of the cells after six weeks and indications that the cells were "well integrated" into the host animals.
