Scientists hunting for culprits that lead to brain damage after strokes have discovered that one likely "bad guy" is actually a "good guy."



Newswise - Scientists hunting for culprits that lead to brain damage after strokes have discovered that one likely "bad guy" is actually a "good guy."

In experiments in the laboratory and with mice, the Johns Hopkins researchers found that the chemical prostaglandin-E2 protects brain cells from damage. The finding was completely unexpected, the researchers say, because prostaglandin-E2 causes damage in other tissues and is made by an enzyme, COX-2, known to wreak havoc in the brain after injury. The findings appear in the Jan. 7 issue of the Journal of Neuroscience.......
