New Stroke Treatment

A nontoxic treatment for stroke has been identified by a team of researchers led by Gregory Bix, at Texas A&M College of Medicine, College Station. Researchers have identified a method to exploit one of the brain's self-repair mechanisms to protect nerve cells and enhance brain repair in rodent models of stroke.

The most common form of stroke (ischemic stroke) occurs when a blood vessel that brings oxygen and nutrients to the brain becomes clogged, for example with a blood clot, causing nerve cells in the affected area to die rapidly. In their study, Bix and colleagues detected in rodent models of stroke elevated levels of domain V, a naturally occurring fragment of the molecule perlecan, suggesting it might have a natural role in repairing the brain after a stroke. When administered in these models 24 hours after stroke, perlecan domain V protected nerve cells from death and promoted blood vessel growth, a key component of brain repair. The authors therefore suggest that perlecan domain V could provide a therapy that improves stroke outcome by protecting nerve cells and enhancing brain repair.
