Transfected neutrophils are responsive to soluble stimuli. Neutrophils were transfected with the expression vector pEGFP-p47phoxor with the pEGFP control vector as follows: Neutrophils were resuspended in solution "T" in the presence of the expression vector pEGFP and DNA was transfected using nucleofector program T27. The neutrophils were transferred to a poly-L-lysine – coated chambered glass slide containing 10% FCS-RPMI. Two hours after transfection, the cells were stimulated with PMA (0.1 μg/ml) or fMLP (1 μM) at 37°C for 15 min or 5 min, respectively. The cells were fixed with 3.7% paraformaldehyde and analyzed by confocal microscopy. Transfected neutrophils stimulated with PMA or fMLP can undergo morphological changes represented by the apparition of protrusions of the plasma membrane (arrows). Scale bar = 5 μm. These results are representative of four separate experiments.
