Fig. 2. Peripheral EP3 receptor is required for influenza-induced sickness.

Fig. 2

a,b, Nestin-cre; Ptger3flox (a), Advillin-creER; Ptger3flox mice (b) or Ptger3flox (a,b) mice were infected with influenza A virus and monitored as indicated. Data are mean ± s.e.m.; n = 8 mice (Ptger3flox), n = 6 mice (Nestin-cre and Advillin-creER). Two-tailed unpaired t-test as detailed in Fig. 1 for behaviour or physiology analyses; log-rank (Mantel–Cox) test for survival analysis. a, Food intake: P = 0.0126; water intake: P = 0.1006; motility: P = 0.0701; body weight: P = 0.9361; survival: P = 0.7735. b, Food intake: P = 0.0004; water intake: P = 0.0004; motility: P < 0.0001; body weight: P = 0.0004; survival: P = 0.0216. c, The NJP ganglia of Ptger3flox mice were injected bilaterally with AAV-cre, exposed to influenza A virus or saline and monitored as indicated. Data are mean ± s.e.m.; n = 8 mice per group. Ptger3flox, virus—food intake: P < 0.0001; water intake: P < 0.0001; motility: P < 0.0001; body weight: P < 0.0001; survival: P < 0.0001. Ptger3flox; AAV-cre, virus—Food intake: P < 0.0001; water intake: P < 0.0001; motility: P < 0.0001; body weight: P < 0.0001; survival: P = 0.0376. One-way ANOVA with Dunnett’s multiple comparison test as detailed in Fig. 1 for behaviour or physiology analyses; log-rank (Mantel–Cox) test for survival analysis, with comparisons made between Ptger3flox, virus and Ptger3flox; AAV-cre, vehicle (red stars) or between Ptger3flox, virus and Ptger3flox; AAV-cre, virus (blue stars).
