Looking Through the Heart. When fatty plaques are deposited in our arteries, white blood cells move from the blood into the vessel wall, and the wall becomes inflamed. The cells in this image are producing actin (red) and collagen (green). The cells’ nuclei are coloured blue. “Both actin and collagen play a key role in recruiting white blood cells when tissue becomes inflamed. A better understanding of how white blood cells interact with different components of the vessel wall will help us identify new ways to treat the inflammatory conditions that underlie cardiovascular disease.” Dr Mathieu-Benoit Voisin & Miss Doris Proebstl, William Harvey Research Institute, Barts and The London School of Medicine and Dentistry, Queen Mary, University of London
