Objective To investigate the influence of phosphodiesterases 4 inhibitor on the phagocytosis of non-biological particles and gram-positive bacteria, gram-negative bacteria by human alveolar macrophages. Methods Peripheral blood mononuclear cells (PBMCs) were isolated from venous blood from 12 healthy volunteers using Ficoll-Hypaque density gradients. Monocytes were incubated with media containing 2 ng/ml GM-CSF for 12d to allow full differentiation into macrophage (MDM), a functionally equivalent model of human AM. MDM were pretreated with Rolipram overnight (16-18h),phagocytosis of fluorescent labeled beads and H.influenzae,S.aureus by MDM was measured using a fluostar optima fluorimeter. Cell viability was assay with MTT. Results MDM phagocytosis of beads and bacteria was a time-dependant process. Rolipram in the concentration of 10^-8-10^-5M didn't inhibit or promote phagocytosis of beads and bacteria by MDM, and didn't affect the cell viability. Conclusion Phosphodiesterases 4 inhibitor would not affect the human macrophage phagocytic capacity of non-biological particles and bacteria associated with enhanced intracellular cAMP level.
