Findings show nanomedicine promising for treating spinal cord injuries

Source: Purdue University
Date: November 8, 2009

Summary:

Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident. The synthetic "copolymer micelles" are drug-delivery spheres about 60 nanometers in diameter, or roughly 100 times smaller than the diameter of a red blood cell. Researchers have been studying how to deliver drugs for cancer treatment and other therapies using these spheres. Medications might be harbored in the cores and ferried to diseased or damaged tissue. Purdue researchers have now shown that the micelles themselves repair damaged axons, fibers that transmit electrical impulses in the spinal cord. Findings are detailed in a research paper appearing Sunday (Nov. 8) in the journal Nature Nanotechnology.

Posted: July 2, 2007 10:45 a.m. PT

Summary:

Animals often attract the opposite sex using chemicals in their scents known as pheromones. The areas of the brain that scientists think pheromones target are also where new cells most often grow in the adult brain — the olfactory bulb, which helps perceive odors, and the hippocampus, which helps store memories. Now researchers have discovered pheromones from dominant male mice stimulated the production of new neurons in female brains.

Pheromones trigger brain cell growth, say researchers

Summary:

The Canadian Broadcasting Corporation reports that pheromones could enable the growth of new brain cells:

"Pheromone signals from dominant males spark new brain cells in their female partners and could help repair injured brains, suggests a new study by a University of Calgary neuroscientist. Sam Weiss's findings, in the July issue of the journal Nature Neuroscience, provide evidence that pheromones — subtle chemical signatures that influence mating behaviour — can control stem cells in the brain."

Date: May 23, 2007

Summary:

Scientific American reports on new observations about the capabilities and functions of new nerve cells in adult brains:

"Researchers have identified a "critical period" during which new nerve cells in adult brains have the same capacity to learn as those in developing brains. The finding in mice, reported in this week's Neuron, provides the promise of therapies that may one day limit or perhaps even reverse the damage of neurodegenerative diseases such as multiple sclerosis and Parkinson's."

Adult Brain Cells Rediscover Their Inner Child

Summary:

You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child. The study, appearing this week in Neuron, suggests that new adult nerves have a deeper role than simply replacing dead ones.

Breakdown of Myelin Implicated in Alzheimer’s, UCLA Research Shows

Source: University of California - Los Angeles
Date: May 10, 2007

Summary:

In a report in the April issue of the journal Alzheimer's & Dementia, UCLA researchers suggest that it is the breakdown of this late-stage myelin, the fatty sheath that coats the axons of the nerves, allowing for efficient conduction of nerve impulses, that promotes the buildup of toxic amyloid-beta fibrils that eventually deposit in the brain and become the plaques which have long been associated with Alzheimer's disease.

When smell cells fail they call in stem cell reserves

Source: Johns Hopkins Medical Institutions
Date: April 29, 2007

Summary:

Hopkins researchers have identified a backup supply of stem cells that can repair the most severe damage to the nerves responsible for our sense of smell. These reservists normally lie around and do nothing, but when neighboring cells die, the scientists say, the stem cells jump into action. A report on the discovery will appear online next week in Nature Neuroscience.

Detailed 3-D Image Catches A Key Regulator Of Neural Stem Cell Differentiation In Action

Source: Salk Institute
Date: December 10, 2006

Summary:

Researchers at the Salk Institute for Biological Studies in collaboration with scientists at the University of California, San Diego (UCSD) took a high resolution "action shot" of a protein switch that plays a crucial role in the development of the nervous system. A finely tuned network of molecular "on" and "off" switches regulates the differentiation of embryonic stem cells into different tissue types. Being able to manipulate individual switches would allow scientists to nudge embryonic stem cells into becoming specific cell types, a plus for both basic research and potential therapies.
