Removing protein makes non-stick arteries
Stray platelets from our blood can stick to the linings of our blood vessels, eventually causing clogs, heart attacks and strokes. But platelets make poor targets for heart disease drugs; making platelets less prone to clogs makes the owner of the platelets more prone to bleeding and infections.
Now, a team of UConn School of Medicine immunologists led by Patrick Murphy and members of the ImmunoCardiovascular Group, Anthony Vella and Annabelle Rodriguez, show that the lining of blood vessels is a much better drug target. They report in the 18 July issue of PNAS that removing a specific protein, Ptbp1, prevents the lining from becoming sticky and inflamed and forming the plaques of platelets linked to heart attack and stroke.
