Built-in bypass bolstered by key molecule
UNC-CHAPEL HILL(US)—An abundance of tiny specialized blood vessels, called collaterals, can reduce damage caused by a blocked artery—such as stroke, heart attack, or leg injury—by enlarging to create a natural bypass. Research shows that this ability is related to levels of nitric oxide, a key signaling molecule. Continue…

Workouts strengthen endothelial cells’ grasp
U. PENN (US)—Bioengineers have demonstrated that the cells that line blood vessels respond to mechanical forces—the microscopic tugging and pulling on cellular structures—by reinforcing and growing their connections, thus creating stronger adhesive interactions between neighboring cells. (more…)

Fewer blood cells may signal preeclampsia
U. PITTSBURGH (US)—Compared to women with uncomplicated pregnancies, women with preeclampsia have reduced numbers of special cells that are thought to help grow and maintain blood vessels. Preeclampsia is the leading cause of preterm labor. (more…)

To understand GI infections, learn the language
TEXAS A&M (US)—New technology is able to mimic the unique bacteria-laden environment of the human GI tract because it knows how to decode the complex way cells “talk” to each other, a new study reports. (more…)

Plaque buildup may be linked to stiffening arteries
CORNELL (US)—Joints are not the only parts of our body that stiffen as we age. Our blood vessels do, too. In more than half of the U.S. population over 65, this stiffening of the blood vessels is accompanied by a buildup of plaque inside arterial walls, known as atherosclerosis, which can increase the risk of a heart attack.
