Altered protein shapes may explain differences in some brain diseases
Wednesday, Jul 3, 2013
It only takes one bad apple to spoil the bunch, and the same may be true of certain proteins in the brain. Studies have suggested that just one rogue protein (in this case, a protein that is misfolded or shaped the wrong way) can act as a seed, leading to the misfolding of nearby proteins. According to an NIH-funded study, various forms of these seeds — originating from the same protein — may lead to different patterns of misfolding that result in neurological disorders with unique sets of symptoms.

Officials at the National Institute of Neurological Disorders and Stroke (NINDS) hailed the identification of a gene associated with the familial form of ALS (Lou Gehrig's disease). "This discovery is extremely important because it marks the first identification of a specific gene for a neurodegenerative disease of adult life," said Carl M. Leventhal, M.D., director of the NINDS program that contributed to support for the research reported in the March 3 issue of Nature*. "It also suggests a likely mechanism for the damage to nerve cells in familial ALS and, possibly, other brain disorders."

NINDS Scientists Isolate Segments Of DNA Sequence That Identify More Than 2,300 Brain Genes
Wednesday, Feb 12, 1992
Using a novel strategy, scientists from the National Institute of Neurological Disorders and Stroke have isolated segments of DNA sequence that uniquely identify more than 2,300 brain genes. The recent data, combined with data from 347 segments sequenced earlier by NINDS scientists, doubles the total number of human genes identified by sequencing, scientists report in the February 13 issue of Nature.

NINDS Scientists Develop Strategy To Speed Gene and Brain Research
Thursday, Jun 20, 1991
Using a novel strategy, scientists at the National Institute of Neurological Disorders and Stroke (NINDS) have isolated key identifying regions of more than 400 genes that work inside the human brain. The scientists say their work should help identify genetic defects that cause brain disease and speed progress of genetics research.
