Figure 6. IVIg treatment reduces neuronal cell death in vivo following ischemic stroke.
a. Intravenously-injected IVIg reached the brain as a result of blood brain barrier breakdown. (Scale bars: 100 μM.) b-d. MAP2-positive neuronal cells were significantly decreased in number in infarcted brain area whereas the treatment with IVIg in both pre- and post-treatment significantly reduced the amount of neuronal loss in infarcted area. ***, P < 0.05 compared to MCAO/R group; n = 3-6 in each group. e and f. TUNEL staining showed that both pre- and post-treatment of IVIg decreased the amount of cell apoptosis in the infarcted region of the brain. ***, P < 0.05 compared to MCAO/R group; n = 3-6 in each group.
