The plaque contains a dysfunctional buildup of immune macrophages (pink) and protein waste (green) (Photo courtesy of Dr. I. Sergin, Washington University School of Medicine).

Macrophages Lacking Ubiquitin-Binding Protein Stimulate Growth of Atherosclerotic Plaques

In a mouse model of atherosclerosis it was shown that while lack of the autophagy chaperone protein p62 prevented ubiquinated dysfunctional proteins from being sequestered in vesicles in the cytoplasm of macrophages, the presence of these proteins in the cell contributed to increased macrophage infiltration into atherosclerotic plaques and exacerbated atherosclerosis.  More...

Image: On the left are fluorescence-labeled cells with nanoparticles: The cellular nuclei are shown in blue, the fluorescence labeling is shown in green, and the nanoparticles in the cells are identified by arrows. The middle photo shows a blood vessel populated with these cells (green). On the right is a detailed image of a vascular wall with the eNOS protein identified (red) (Photo courtesy of Dr. Sarah Rieck/Dr. Sarah Vosen, University of Bonn).

Novel Combination of Nanotechnology and Gene Therapy Repairs Damaged Arterial Walls
