Cells were pretreated for 30 min with the A1-receptor antagonist DPCPX or the A2a-receptor antagonist CSC or the A3-receptor antagonist MRS-1220 at a concentration of 1 μM, and were then stimulated for 24 h with 1 mM of the indicated nucleotide. Supernatants were then collected and IL-8 content was determined by ELISA. Data are expressed as mean±s.e.m. (n=3).
