Effect of sulfide and polysulfide on cell viability of SH-SY5Y cells and primary cortical neurons incubated with MPP+
(A) SH-SY5Y cells or (B and C) murine primary cortical neurons were incubated with or without MPP+ with or without trisulfide compounds at 37 °C for 24 h. Cell viability was measured using the crystal violet assay (n = 4 or 5 each). *, **, ***p < 0.05, 0.01, 0.001 vs. control without trisulfide treatment.
