Differential mRNA expression of COX-2 and PGE 2 /LTB 4 receptors induced by Mtb isolates 97-1200 and 97-1505. mRNA expression of (A) 5-LO, FLAP, and BLT1, and (B) COX-2, EP-2, and EP-4 in alveolar macrophages infected for 6 and 12 h with Mtb isolates 97-1200 and 97-1505. Dotted lines show the relative expression of uninfected cells (fold change = 1). All samples were normalised by Gapdh endongenous control. ***P < 0.0001; *P < 0.05 (one-way ANOVA). Data are representative of two independent experiments (error bars, s.e.m.).
