L-Arginine uptake is enhanced in resistant compared with susceptible transfectants following activation with LPS plus IFN γ

Results are expressed as the percentage stimulation (standard deviation) observed in LPS + IFNγ-treated macrophages compared with untreated controls. Asterisks indicate significance levels (*p < 0.05; **p < 0.01; ***p < 0.001) for results of student’s t-tests used to compare each resistant transfectant against the susceptible transfectants 2S, 10S and 30S. Results are representative of five independent experiments performed.
