Effect of low dose L-DOPA on CD39 protein expression.

<p>PC12 cells were treated with L-DOPA at different concentration for 3 days, and CD39 protein expression was measured by immunofluorescence staining (A) and western blot assay (B). L-DOPA treatment resulted in an increase in CD39 expression when compared with un-treated group and peaked at 10 µM L-DOPA (C). *P<0.05 vs. untreated group. #P>0.05 vs. untreated group.
