Figure Lengend Snippet: Anti-IL36R treatment inhibits systemic inflammation in K14-IL17A ind mice. (A) Flow cytometry analysis of the bone marrow from Ctrl mice or K14-IL17A ind mice that either received IgG or anti-IL36R treatment (n = 2-3 animals per group). The relative percentage of positive cells is shown after pre-gating on viable cells. (B) Oxidative burst was measured in venous blood of control or K14-IL17A ind mice by analyzing the formation of reactive oxygen and nitrogen species. Blood cells were either restimulated with phorbol-12,13-dibutyrate (PDBu) or with Zymosan A. After addition of the 8-amino-5-chloro-7-phenylpyridol-(3,4-d)pyridazine-1,4-(2H,3H)-dione sodium salt (L-012), the oxidative burst was detected by the created chemiluminescence using a SparkTM Multimode Microplate Reader. n = 4-5. C + D. Gene expression analysis of the spleen (C) and colon (D) from treated mice. Shown is the relative gene expression normalized to β-Actin (C) or Rpl37A (D) for n = 3-4 animals per group. Significance was calculated using a 2-tailed Student’s t-test: * p < 0.05, ** p < 0.01, *** p< 0.001. Shown is the mean ± SEM. (E) H&E staining of the colon at the endpoint. Scale: 100 µm.
Article Snippet: After the addition of the chemiluminescence dye 8-amino-5-chloro-7-phenylpyridol-(3,4-d)pyridazine-1,4-(2H,3H)-dione sodium salt (L-012), the created chemiluminescence directly correlating with the underlying ROS formation was measured, using a Spark™ Multimode Microplate Reader (Tecan Trading AG, Männedorf, Switzerland).
