Protein identified that plays role in blood flow

Thursday, September 18, 2008 - 11:21 in Health & Medicine

For years, researchers have known that high blood pressure causes blood vessels to contract and low blood pressure causes blood vessels to relax. Until recently, however, researchers did not have the tools to determine the exact proteins responsible for this phenomenon. Now, using atomic force microscopy - a microscope with very high resolution - and isolating blood vessels outside the body, University of Missouri researchers have identified a protein that plays an important role in the control of tissue blood flow and vascular resistance. This new knowledge brings researchers one step closer to understanding vascular diseases, such as high blood pressure, diabetes and other vascular problems.
