Figure 3From: Microglia P2Y6 receptors mediate nitric oxide release and astrocyte apoptosis Metabolism of uracil nucleotides in lipopolysaccharide (LPS) cultures. Cells were incubated with 0.1 mM of (A) UTP or (B) UDP and samples were collected at 0, 1, 3, 8, 24 and 48 h. Uracil nucleotides and their metabolites were quantified by HPLC-UV. Values are means ± SEM from four experiments.Back to article page
