Double-label immunocytochemical analysis for TH- and NeuN-IR neurons. Rat neuron–glia cultures treated for 8 d with vehicle (Control) or 0.5 nmrotenone and 0.5 ng/ml LPS were double immunostained with anti-TH and anti-NeuN antibodies. The images are from one experiment that is representative of three separate experiments. Scale bar, 50 μm.Arrowheads, TH-IR neurons.
