Gation. P2Y1 Receptor Source Colonoscopy was performed working with a flexible digital ureteroscope around the day 7 of DSS remedy. For a full description, see SI Components and Techniques. BM Chimeric Mice. Mice receiving BM transfer had been irradiated (900 radiation absorbed dose) quickly prior to transplantation. BM was harvested from femurs and tibias of 4-wk-old SAMP or AKR mice. To get a full description, see SI Materials and Approaches. Myeloperoxidase Assay Activity. Colon samples have been assayed for myeloperoxidase (MPO) activity as previously described (31, 32). For any full description, see SI Components and Strategies. Salmonella Infection Assays. Salmonella infection assays have been performed as previously described (9). For a complete description, see SI Materials and Strategies. Salmonella Infection in Vivo. SAMP and AKR manage mice (four wk) had been infected with Salmonella for two d. To get a complete description, see SI Components and Procedures. Statistical Analysis. Analyses of continuous data had been carried out working with parametric Student t tests, one-way or two-way ANOVAs, or linear regression (when acceptable), or their nonparametric alternatives. For a complete description, see SI Components and Approaches. ACKNOWLEDGMENTS.
