Human CD14⁺ monocytes were cultured for 36 hours in macrophage serum-free medium and granulocyte-macrophage colony-stimulating factor and then were infected with adenovirus-GFP (200 plaque-forming units per cell) or treated with lipopolysaccharide (50 ng/mL). At 48 hours later, supernatants were assayed for the indicated chemokines. Results are expressed in nanograms per milliliter.

MIP indicates macrophage inflammatory protein; SFM/G, macrophage serum-free medium and granulocyte-macrophage colony-stimulating factor; GFP, green fluorescent protein; and LPS, lipopolysaccharide.
