IL-1 receptor (IL-1R) expression in murine colon during dextran sulfate sodium (DSS)-induced colitis. Mice were given either water alone [no DSS (control); day 0] or 3.0% w/v DSS for 3, 5, or 7 days. A: Hematoxylin and eosin (H&E) staining of colons. B and C: Immunostaining of murine IL-1R. Images were captured with a Leica DMR upright microscope with a Retiga EXi Cooled CCD camera with liquid crystal tunable RGB filter using Image-Pro Plus software. n = 5 mice per group (images are representative of three mice per group) (A). Images were obtained with 2.5× objective (A and B) or 10× objective (C).
