NOS2 and infection: Data showed no significant increase in iNOS recruitment to M. tuberculosis-GFP in LV-EBP50-transduced macrophages compared with untreated cells (15.7% ± 5.3% vs. 14.1% ± 3.6%, P > 0.05) and LV-Lenti transduced cells (15.7% ± 5.3% vs. 14.8% ± 4.9%, P > 0.05) at 4 h after infection (Fig. 1).
