1 RT–PCR‐southern hybridization analyses with radiolabelled P2Y receptor cDNAs as
probes indicated that the peripheral blood leukocytes and the human umbilical vein
endothelial cells express P2Y1, P2Y2, P2Y4 and P2Y6 receptors. 2 Of the haematopoietic
cell lines tested, promonocytic U937 cells express P2Y2 and P2Y6, but not P2Y1 or P2Y4;
promyelocytic HL‐60 cells express the P2Y1, P2Y2 and P2Y6 receptors but not the P2Y4
receptor; K562 cells express P2Y1 but not P2Y2, P2Y4 or P2Y6; and Dami cells express …

    Of the peripheral blood leukocytes tested, polymorphonuclear cells express P2Y4 and P2Y6 but not P2Y1 or P2Y2 receptors; monocytes express P2Y1, P2Y2, P2Y4 and P2Y6 receptors and lymphocytes express P2Y1, P2Y2, P2Y4 and P2Y6 receptors.

    These results suggest a physiological role for different P2Y receptor subtypes in the extracellular nucleotide‐mediated stimulation of monocytes, neutrophils, lymphocytes and endothelial cells.
