EurekAlert! -- A new study by researchers at the Swedish medical university Karolinska Institutet shows that the immune defence’s T cells can attack the “bad” LDL cholesterol and thereby cause an inflammation that leads to atherosclerosis. By producing a vaccine against the T cell receptors, the researchers have managed to inhibit the development of atherosclerosis in animals. The study is presented online in the distinguished periodical Journal of Experimental Medicine and is expected to be of considerable significance to the future treatment of atherosclerosis, heart attack and stroke.
