NAC protects DA cell bodies and neurites from MPP⁺-induced degeneration. A, Dissociated DA neurons were pretreated with 2.5 mm NAC for 18 h, treated with 2 μm MPP⁺ for 24 h, and then fixed and immunostained with rabbit polyclonal anti-TH antibody. Scale bar: 10 μm B, Quantification of TH-positive cell bodies and neurites. Cell bodies and neurites were significantly protected by NAC. Mean ± SEM from three independent experiments, *p < 0.05, compared to control, ^#p < 0.05, ^##p < 0.001, compared to MPP⁺.
