Latino Post: Researchers took macrophages from old mice and humans with macular degeneration and discovered they had low levels of ABCA1, a protein that transports cholesterol from cells. The researchers then worked to activate receptors that would affect ABCA1 expression in mice, with the help of cholesterol-lowering drugs. They tested two types of drugs, finding both medications increased ABCA1 levels and improved cholesterol transport in macrophages --- thereby reducing the growth of new blood vessels.
