Pharmacological manipulations HH2R receptor activity indicates positive regulation of il-1β expression by the receptors. A: Representative images of the injury site in il-1β:GFP line treated with 10µM cimetidine, or DMSO are shown. B: Quantification of the overall GFP fluorescence relative to DMSO-treated larvae indicates a dose-dependent reduction of GFP fluorescence by Cimetidine treatment (Kruskal-Wallis test with Dunn's multiple comparison test, p*** = 0.0003; DMSO vs 10 µM cimetidine, p* = 0.0250; DMSO vs 50 µM cimetidine, p*** = 0.0008). C: Representative images of the injury site in il-1β:GFP line treated with 50 µM Betazole, or DMSO are shown. D: Quantification of the overall GFP fluorescence relative to DMSO-treated larvae reveals a dose-dependent increase of GFP fluorescence by Betazole treatment (Kruskal-Wallis test with Dunn's multiple comparison test, p* = 0.0145, DMSO vs 50 µM Betazole, p* = 0.0422; DMSO vs 100 µM Betazole, p* = 0.0473). Scale bars: 100 µm.
