**Article Title: **Inhibition of rat locus coeruleus neurons by prostaglandin E 2 EP3 receptors: pharmacological characterization ex vivo

**Journal: **Frontiers in Pharmacology

**doi: **10.3389/fphar.2023.1290605

**Figure Legend Snippet:**Effect of the EP3 receptor agonist sulprostone on the firing rate of LC neurons in the presence of the EP2 receptor antagonist PF-04418948 or the EP4 receptor antagonist L-161,982. (A,B) Representative examples of firing rate recordings of two LC neurons showing the effect of increasing concentrations of sulprostone in the presence of PF-04418948 (10 µM) (A) or L-161,982 (10 µM) (B) . The vertical lines represent the number of spikes recorded every 10 s and the horizontal bars the period of drug application. (C,D) Concentration-effect curves for sulprostone in control (filled squares) and in the presence of PF-04418948 (3 μM, open triangles or 10 μM, filled triangles) (C) or L-161,982 (3 μM, open diamonds or 10 μM, filled diamonds) (D) . The horizontal axes show the sulprostone concentration on a semi-logarithmic scale. The vertical axes express the reduction in firing rate of LC neurons as the percentage of the baseline. Data points are the mean ± SEM at each sulprostone concentration obtained from n number of experiments. The lines through the data are the theoretical curves in each group constructed from the mean of the individual concentration-effect curve parameters, as estimated by nonlinear regressions.

**Figure Legend Snippet:**Effect of PGE 2 on the firing rate of LC neurons in the absence or presence of the EP3 receptor antagonist L-798,106 or a combination of the EP2 receptor antagonist PF-04418948 and the EP4 receptor antagonist L-161,982. (A,B) Representative examples of firing rate recordings of two LC neurons showing the effect of increasing concentrations of PGE 2 in the absence (A) and presence of L-798,106 (10 µM) (B) . The vertical lines represent the number of spikes recorded every 10 s and the horizontal bars the period of drug application. (C) Concentration-effect curves for PGE 2 in control (filled squares) and in the presence of L-798,106 (10 μM, filled circles) or PF-04418948 and L-161,982 (10 µM each, half-filled diamonds). The horizontal axis shows the PGE 2 concentration on a semi-logarithmic scale. The vertical axis expresses the reduction in firing rate of LC neurons as the percentage of the baseline. Data points are the mean ± SEM at each PGE 2 concentration obtained from n number of experiments. The lines through the data are the theoretical curves in each group constructed from the mean of the individual concentration-effect curve parameters, as estimated by nonlinear regressions. Note that the concentration-effect curve for PGE 2 is shifted to the right by the EP3 receptor antagonist and to the left by the EP2 and EP4 receptor antagonists.

Data are mean ± s.e.m.; n = 10 mice for vehicle groups; n = 8 mice for all others. For EP3 antagonist—food intake: P < 0.0001; water intake: P < 0.0001; motility: P < 0.0001; body weight: P = 0.0002; survival: P = 0.0094. b , c , Two-tailed unpaired t -test, with comparisons between groups treated with ibuprofen or EP3 antagonist and vehicle in c . Log-rank (Mantel–Cox) test for survival analyses; for behavioural or physiological changes, a mean daily change in behaviour (days 1–10 after infection or survival) was obtained for each mouse, and then used for comparisons across experimental groups (for more information see Extended Data Fig. ). * P < 0.05, ** P < 0.005, *** P <0.0005; NS, not significant.
