Fig. 7. Effects of α-synuclein inhibition on VPA-induced neuroprotection in primary cortical neurons. A. Primary cortical neurons in serum-free MEM were treated with VPA (1 mM) and α-synuclein Ab (10 μg) 1 hr before H₂O₂ treatment for 24 hr at 37℃. Cell viability was measured by MTT reduction assay. Values are expressed as the mean ± S.E.M. **p<0.01 vs. control; ^##p<0.01 vs. H₂O₂.
