Research Abstract

Protein misfolding disease, such as Alzheimer's' disease(AD), is caused by misfolded protein aggregates that induce molecular stress and interfere with cellular function. We examined effect of molecular chaperone prefoldin(PFD) on aggregation of amyloid beta and poly glutamine protein that cause AD and Huntington disease, respectively. We found that PFD could inhibit their aggregation in vitro.
