A brilliant monomeric red fluorescent protein to visualize cytoskeleton dynamics in Dictyostelium.

abstract：:The formation of fibrils by amyloid beta-protein (Abeta) is considered as a key step in the pathology of Alzheimer's disease (AD). Inhibiting the aggregation of Abeta is a promising approach for AD therapy. In this study, we used biocompatible nanogels composed of a polysaccharide pullulan backbone with hydrophobic ch...
