1 Recently, the hP2Y6 receptor has been reported to mediate monocyte IL-8 production in response to UDP or lipopolysaccharide (LPS), but the role of hP2Y6 in regulating other pro-inflammatory cytokines or mediators is largely unknown. Uridine Diphosphate C-X-C motif chemokine ligand 8 Homo sapiens
2 We demonstrate here that UDP specifically induces soluble TNF-alpha and IL-8 production in a promonocytic U937 cell line stably transfected with hP2Y6. Uridine Diphosphate C-X-C motif chemokine ligand 8 Homo sapiens
3 Interestingly, UDP induces the production of IL-8, but not TNF-alpha, in human astrocytoma 1321N1 cell lines stably transfected with hP2Y6. Uridine Diphosphate C-X-C motif chemokine ligand 8 Homo sapiens
4 From the Taqman analysis, UDP stimulation significantly upregulates the mRNA levels of IL-8, IP-10, and IL-1beta, but not TNF-alpha. Uridine Diphosphate C-X-C motif chemokine ligand 8 Homo sapiens
