- Chemical maps hint at drug's effects on schizophrenia
05-15-2007 · EurekAlert!
Antipsychotic drugs do most of their work in the brain, but they also leave behind in the bloodstream a trail of hundreds of chemicals that may be used in the future to direct better treatment for schizophrenia and other psychiatric conditions, say Duke University Medical Center researchers.

- How 'IAP antagonist' chemicals kill tumors
11-15-2007 · EurekAlert!
Chemical compounds specially designed to neutralize proteins that would otherwise allow tumor cells to cheat death have been recognized for some time by scientists as a promising new avenue for cancer therapy. Now, two studies in the Nov. 16, 2007 issue of the journal Cell, a publication of Cell Press, provide insight into just how these antagonists of the anti-death -- so-called Inhibitor-of-Apoptosis (IAP) -- proteins work to fight tumors.

- Similar brain chemicals influence aggression in fruit flies and humans
04-22-2007 · EurekAlert!
Serotonin is a major signaling chemical in the brain, and it has long been thought to be involved in aggressive behavior in animals and humans. Another brain chemical signal, neuropeptide Y (aka neuropeptide F in invertebrates), is also known to affect an array of behaviors in many species, including territoriality in mice. A new study at The Neurosciences Institute (San Diego) shows that these two chemicals also regulate aggression in the fruit fly, Drosophila melanogaster.

- New depression model advances disease frontiers
11-09-2006 · EurekAlert!
For over 30 years, scientists believed that monoamines are low in the brain during major depressive episodes. However, no one ever found a convincing explanation for monoamine loss. Dr. Jeffrey Meyer and colleagues discovered that higher levels of MAO-A is the primary process that lowers monoamine levels. Having more MAO-A leads to greater breakdown of chemicals like serotonin. Based on these results, and work from previous publications, Dr. Meyer developed an advanced monoamine model of depression.

- 'Lab on a chip' mimics brain chemistry
02-12-2008 · EurekAlert!
Johns Hopkins researchers from the Whiting School of Engineering and the School of Medicine have devised a micro-scale tool -- a lab on a chip -- designed to mimic the chemical complexities of the brain. The system should help scientists better understand how nerve cells in the brain work together to form the nervous system.

10-18-2006 · EurekAlert!
For years, the brain chemical dopamine has been thought of as the brain's "pleasure chemical," and studies have linked the addictive properties of drugs like cocaine to their effects on the dopamine system. But now, a new study adds a new twist to dopamine's fun-loving reputation: pain.
