Single Mechanism Seen To Underlie Group Of Neurodegenerative Diseases: Mutant Proteins Form Insoluble Masses In The Nuclei Of Neurons
...including the brain, one question scientists would like
tobe able to answer is why the aggregations occur only in selected populations ofneurons. How and why do the proteins accumulate in the nucleus, instead ofpassing back and forth into the cytoplasm across the nuclear membrane? How isthe mutant protein...
