Findings show how toxic proteins rob Alzheimer's patients of memory

Alzheimer's disease results in memory loss and not other symptoms such as loss of balance or tremors. The research team, led by William L. Klein, professor of neurobiology and physiology, found that toxic proteins, called "amyloid -derived diffusibl...

1990s, PNAs are small synthetic molecules in which a protein-like backbone is combined with the nucleobases found in DNA and RNA. These nucleobases enable PNA to bind to DNA and RNA in a complementary, highly specific manner. Because the cell machine...
