New Insights into the Immunological Changes in IL-10-Deficient Mice during the Course of Spontaneous Inflammation in the Gut Mucosa

IL-10 is a regulatory cytokine that plays a major role in the homeostasis of the gut and this is illustrated by the fact that IL-10−/− mice develop spontaneous colitis. In this study, IL-10−/− mice were analyzed for immunological changes during colitis development. We found a reduced frequency of regulatory T cells CD4
