On the cover: A high salt diet exacerbates histologic pathology in inflamed Il10^−/− mice relative to mice on a low salt diet, as seen by increased immune cell infiltrate, epithelial hyperplasia, and apparent goblet cell loss. This exacerbated inflammation reflects increased inflammatory cytokine expression driven by higher colonic salt content. Tubbs, A. L., B. Liu, T. D. Rogers, R. B. Sartor, E. A. Miao. 2017. Dietary salt exacerbates experimental colitis. J. Immunol. 199: 1051–1059.
