Figure 5From: Naloxone inhibits immune cell function by suppressing superoxide production through a direct interaction with gp91phoxsubunit of NADPH oxidase PMA induces p47 phox and p67 phox translocation to the membrane in COS-7-NOX2 cells. COS-7-NOX2 cells were pretreated with the indicated concentrations of PMA for 20 minutes. Membrane fractions were isolated to perform western blot analysis. Results are expressed as a percentage of the control and are mean ± SEM of three independent experiments performed in duplicate. **P < 0.01 compared with the corresponding control group. PMA, phorbol myristate acetate.Back to article page
