Newborn Neurons in Adult Brain Can Settle in the Wrong Neighborhood

In a study that could have significant consequences for neural tissue transplantation strategies, researchers at the Salk Institute for Biological Studies report that inactivating a specific gene in adult neural stem cells makes nerve cells emerging from those precursors form connections in the wrong part of the adult brain.

Nerve stem cells coaxed into working nerve cells
Darkfrog submitted, created time 6 months 3 weeks (www.medicalnewstoday.com)
Researchers at the UT Southwestern Medical Center have found a number of small compounds that stimulate nerve stem cells to develop into nerve cells. They synthesized a version that they are calling isoxazole-9, or ISX-9. This compound seems to have applications in nerve damage and brain cancer chemotheryapy.
Is Old Age Memory Decline Reversible?

Scientists have found that a lessened supply of new nerve cells in the adult brain apparently triggers short-term memory loss typically associated with aging, setting the stage for one day developing therapies designed to maintain a steady supply of fresh neurons to keep the mind sharp.
Evidence found for novel brain cell communication

An article published today, July 16, 2007, in Proceedings of the National Academy of Sciences provides strong evidence for a novel type of communication between nerve cells in the brain. The findings may have relevance for the prevention and treatment of epilepsy, and possibly in the exploration of other aspects of brain functions, from creative thought processes to mental illnesses such as schizophrenia. The discovery suggests the first new model of brain function since the 1940s.
Doing nature one better: Expanding the genetic code in living mammalian cells
BIOBOSS submitted, created time 1 year 6 months (www.eurekalert.org)
Researchers at the Salk Institute for Biological Studies have developed a novel strategy to expand the natural repertoire of 20 amino acids in mammalian cells, including neurons, and successfully inserted tailor-made amino acids into proteins in these cells. In a powerful demonstration of the method's versatility, they then used unnatural amino acids to determine the operating mechanism of the "molecular gates" that regulate the movement of potassium ions in and out of nerve cells.

The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells. In the first method, developed at the University of Miami, researchers show how magnetic nanoparticles (MNPs) may be used to create mechanical tension that stimulates the growth and elongation of axons of the central nervous system neurons
Growing Nerve Cells In 3-D Dramatically Affects Gene Expression

Nerve cells grown in three-dimensional environments deploy hundreds of different genes compared with cells grown in standard two-dimensional petri dishes, according to a new Brown University study. The research, spearheaded by bioengineer Diane Hoffman-Kim, adds to a growing body of evidence that lab culture techniques dramatically affect the way these cells behave.
Scientists identify key to integrating transplanted nerve cells into injured tissue

"Scientists at the Schepens Eye Research Institute, an affiliate of Harvard Medical School, have identified a key mechanism for successfully transplanting tissue into the adult central nervous system. The study found that a molecule known as MMP-2 (which is induced by stem cells) has the ability to break down barriers on the outer surface of a damaged retina and allow healthy donor cells to integrate and wire themselves into remaining recipient tissue. "
The Brain May Use Only 20 Percent of Its Memory-Forming Neurons
medal submitted, created time 1 year 8 months (www.sciam.com)
"Remember the old myth that people only use 10 percent of their brains? Although a new study confirmed that bromide to be apocryphal, it did find that we may only use 20 percent of the nerve cells in our midbrain to form memories. "
Stem cell study zeroes in on ALS cause
alpha submitted, created time 1 year 8 months (www.reuters.com)
"Cells that are supposed to nourish and support other nerve cells instead secrete the poisons that cause amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, researchers reported on Sunday."
