Another Rochester neuroscientist, Timothy Collier, has already begun looking into freezing and storing fetal brain tissue for use in implants. He reported last week that he had successfully transplanted frozen-and-revived fetal neural tissue in both rats and monkeys. The next step: implanting the thawed tissue into monkeys afflicted with Parkinson's. The ultimate aim is to create neural-tissue banks that surgeons will be able to draw on for future operations...
Peptide T, another promising substance for curbing the virus, received mixed reviews. Last December, Neuroscientist Candace Pert of the National Institute of Mental Health reported that the chemical, a synthetic portion of a protein on the AIDS virus that helps it bind to cells, seemed to prevent the virus from entering cells. In May the FDA approved clinical trials, and last week Oncogen, a Seattle biotechnology company, announced that its researchers had confirmed Pert's findings. But Dr. William Haseltine, a virologist at Harvard's Dana Farber Cancer Institute, said neither his laboratory nor six others around the world...
...estimated 1 million Americans with Parkinson's disease, the Mexican research offers new hope. "If these results turn out to be valid and replicable, this would be a major advance," says Neuroscientist William Freed of the National Institute of Mental Health. Current treatments for Parkinson's are far from ideal. Levodopa, which is chemically related to dopamine, can cause irregular heartbeats, paranoia and depression, and ceases to be effective after prolonged use. Freed and others are eager to see if the new technique will work in older patients (most Parkinson's victims are over 50), and if its benefits will...
...there is much more capacity for response to brain injury than previously thought." The same conclusion has been reached by researchers who have regenerated nerve fibers in other parts of animals' brains as well as in their spinal cords. At Saint Elizabeths Hospital in Washington, D.C., for instance, Neuroscientist William Freed has treated rats with fetal cell implants to relieve symptoms resembling Parkinson's disease in humans. The implanted cells are capable of producing dopamine, a vital brain chemical lacking in the afflicted rats and in Parkinson's patients. Such techniques used with humans, some researchers believe...
