Molecular 'foreman' discovered for brain wiring
11-21-2007 · EurekAlert!Researchers have identified a master regulatory molecule that is responsible for triggering the remodeling of neuronal connections that is critical for learning. Malfunctioning of the connection-remodeling machinery that they identified may also play a role in mental retardation, schizophrenia, and drug addiction. Thus, said the researchers, knowledge of the machinery could lead to insights into those disorders. Peter Penzes and colleagues published their findings in the Nov. 21, 2007, issue of the journal Neuron, published by Cell Press.

- Penn researchers discover initial steps in the development of taste
12-05-2006 · EurekAlert!
Researchers at the University of Pennsylvania School of Medicine are closer to understanding how the sense of taste develops. They have pinpointed a molecular pathway that regulates the development of taste buds. Using genetically engineered mice, they discovered that a signaling pathway activated by small proteins called Wnts is required for initiating taste-bud formation. They have also determined that Wnt proteins are required for hooking up the wiring of taste signals to the brain.

- Mayo discovers link between Huntington's and abnormal cholesterol levels in brain
12-01-2006 · EurekAlert!
Mayo Clinic researchers have discovered a protein interaction that may explain how the deadly Huntington's disease affects the brain. The findings, published in and featured on the cover of the current issue of Human Molecular Genetics, show how the mutated Huntington's protein interacts with another protein to cause dramatic accumulation of cholesterol in the brain.

- Chemical signature of manic depression discovered by scientists
02-05-2008 · EurekAlert!
People with manic depression have a distinct chemical signature in their brains, according to a new study. The research, published today in the journal Molecular Psychiatry, may also indicate how the mood stabilisers used to treat the disorder counteract the changes in the brain that it appears to cause.

- A molecule that protects from neuronal disorders
09-14-2007 · EurekAlert!
Researchers from the Mouse Biology Unit of the European Molecular Biology Laboratory in Italy, have now discovered that a protein that helps organising the cells' skeleton is crucial for preventing mental retardation and other neuronal disorders. In the current issue of Genes & Development they report that mice lacking the protein show symptoms of lissencephaly brought about by faulty development of the cerebral cortex, the brain's surface layer.

- OHSU researchers reveal the science of shivering
12-17-2007 · EurekAlert!
OHSU researchers have uncovered the system that tells the body when to perform one of its most basic defenses against the cold: shivering. The scientists have discovered the brain's wiring system, which takes temperature information from the skin and determines when a person should start shivering. Their findings are published in the advance online edition of the journal Nature Neuroscience.

- AIDS interferes with stem cells in the brain
08-15-2007 · EurekAlert!
Scientists at the Burnham Institute for Medical Research have discovered how HIV/AIDS disrupts the normal replication of stem cells in the adult brain, preventing new nerve cells from forming. Drs. Stuart Lipton, Marcus Kaul, Shu-ichi Okamoto and colleagues uncovered a novel molecular mechanism that inhibits stem cell proliferation and that could possibly be triggered in other neurodegenerative diseases. These findings were published today online by the journal Cell Stem Cell.

- A molecular switch is linked to a common breast cancer
11-08-2007 · EurekAlert!
Researchers have discovered that a molecular switch in the protein-making machinery of cells is linked to one of the most common forms of lethal breast cancer worldwide. The discovery by researchers at NYU School of Medicine could lead to new therapies for the cancer, called locally advanced breast cancer.

- A new way of classifying addictive drugs
11-13-2006 · EurekAlert!
Although addictive drugs have diverse molecular targets in the brain, they share the common initial effect of increasing the concentration of a substance called dopamine. In an article in PLoS Medicine, researchers Christian Lüscher (University of Geneva) and Mark A. Ungless (Imperial College London) review recent research that has advanced our understanding of the molecular mechanisms underlying this increase of dopamine. Based on this research, they propose a new classification for addictive drugs.
