Gene Linked to Alzheimer's Disease Plays Key Role in Cell Survival – 3
Narrator: This is NIH Health Matters. I’m Joe Balintfy. A recent study shows that mutations in a particular gene increase the amount of toxic proteins in the brain.
Refolo: Often what happens is that these toxic proteins not only accumulate in the cell itself, but get outside of the cell.
Narrator: Dr. Lorenzo Refolo is at the National Institute on Aging.
Refolo: And this is also very bad because then they can affect not only the cell that's producing them but the cells surrounding that cell and it’s almost like a domino effect and these proteins get out sort of get loose and do their bad, dirty work in the brain.
Narrator: For more on the study visit www.nia.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
