The effects of adenosine analogs on human polymorphonuclear leukocyte (PMN) phagocytosis to latex beads or sheep red blood cells were investigated in an in vitro experiment. The purine compounds such as N6-phenylisopropyladenosine (PIA), 5'-N-ethylcarboxamido-adenosine (NECA), an A2 adenosine receptor agonist, and adenosine as high as 2 mM had no effect on PMN phagocytosis. In contrast, 2',5'-dideoxyadenosine (DDA), a P-site adenosine receptor agonist, and 5'-methylthioadenosine (MTA), a naturally occurring purine nucleoside, caused profound inhibition of phagocytic function of PMNs in a dose-dependent manner. Dipyridamole, which blocks purine nucleoside uptake, reversed the suppression due to MTA. Theophylline, an R-site receptor antagonists did not prevent the effect of MTA. These results suggested that phagocytosis of PMNs is suppressed by stimulation of the P-site adenosine receptors.
