Clot dissolver tPA’s tardy twin could aid in stroke recovery

Emory researchers led by neurologist Manuel Yepes, MD have identified a protein released by neurons while the brain is recovering from a stroke. The results were published online today in Journal of Neuroscience.

The protein, called urokinase-type plasminogen activator or uPA, has been approved by the FDA to dissolve blood clots in the lungs. It has been tested in clinical trials in some countries as a treatment for acute stroke.

The Emory team’s findings suggest that in stroke, uPA’s benefits may extend beyond the time when doctors’ principal goal is dissolving the blood clot that is depriving the brain of blood.
Instead, uPA appears to help brain cells recover from the injuries induced by loss of blood flow. Treating mice with uPA after an experimental stroke can improve their recovery of motor function, the researchers found.
