Scientists at Emory University School of Medicine are testing strategies for blocking LRP1, a molecule that appears to transmit inflammation signals triggered by tPA. They have found that in mice, genetically removing LRP1 from certain brain cells called microglia softens tPA's impact on the brain.

ATLANTA--Since the introduction of the life-saving clot-busting drug tPA more than a decade ago, evidence has been accumulating that tPA (tissue-type plasminogen activator) can be a double-edged sword for a brain affected by stroke. Although it remains the only FDA-approved treatment for acute stroke, tPA can also contribute to inflammation and brain cell damage.
