Findings may lead to new drug targets for treating schizophrenia
A mouse study reported in this weeks Science magazine shows that three drugs, each acting on a different chemical transmitter in the brain, all produce the same schizophrenia-like symptoms by acting on a single "master molecule" in the brain.
The findings, reported by researchers at Rockefeller University with collaboration from three pharmaceutical and biotech companies, provides, for the first time, a cellular model detailing how this crucial protein, known as DARPP-32, interacts with multiple neurotransmitter systems to produce behavior.
The scientists demonstrate that DARPP-32 acts like the thin neck in an hourglass, through which all signals taken into a nerve cell must pass and be processed, producing a wide variety of biochemical reactions. In this case, three different drugs of abuse, LSD, PCP ("angel dust") and amphetamine, work on three different neurotransmitters, serotonin, glutamate, and dopamine, respectively. All three drugs, which are classified as psychotomimetics or psychostimulants, are processed within the DARPP-32 hourglass neck through the same pathway, thus producing very similar physiological symptoms.

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.
The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
Researchers at the University of Zurich show that different stem cell populations are innervated in distinct ways. Innervation may therefore be crucial for proper tissue regeneration. They also demonstrate that cancer stem cells likewise establish contacts with nerves. Targeting tumour innervation could thus lead to new cancer therapies.
Stem cells can generate a variety of specific tissues and are increasingly used for clinical applications such as the replacement of bone or cartilage....
