IL-10 is a potent regulator of the innate and adaptive immune responses. Several cell types produce IL-10 and its receptor chains and these may regulate different immune responses. Here we report that inactivation of the IL-10 receptor (IL-10R1) gene in mice leads to an increased susceptibility to chemically induced colitis as in the classical(More)
The common cytokine receptor chain, gp130, controls the activity of a group of cytokines, namely, IL-6, IL-11, IL-27, ciliary neurotrophic factor (CNTF), leukemia inhibitory factor (LIF), oncostatin M (OSM), cardiotrophin-1 (CT-1), cardiotrophin-like cytokine (CLC) and neuropoietin (NPN). This family of cytokines is involved in multiple different biological(More)
BACKGROUND Regulatory cytokines are well known to modify experimental colitis in mice. The aim of this study was to elucidate the effect of interleukin (IL)-10 derived from different cellular sources and the effect of commensal gut flora in dextran sulfate sodium (DSS)-induced colitis in mice. METHODS Wildtype (WT) and IL-10 deficient (IL-10(-/-) ) mice(More)
Gp130 is the common receptor of the IL-6 family of cytokines and is involved in many biological processes, including acute phase response, inflammation and immune reactions. To investigate the role of gp130 under inflammatory conditions, T-cell-specific conditional gp130 mice were first bred to the IL-10-deficient background and were then infected with the(More)
Follicular helper T (TFH) cells are specialized in providing help for B cell differentiation and Ab secretion. Several positive and negative regulators of TFH cell differentiation have been described but their control is not fully understood. In this study, we show that Notch signaling in T cells is a major player in the development and function of TFH(More)
Fibroblast-like cells of secondary lymphoid organs (SLO) are important for tissue architecture. In addition, they regulate lymphocyte compartmentalization through the secretion of chemokines, and participate in the orchestration of appropriate cell-cell interactions required for adaptive immunity. Here, we provide data demonstrating the functional(More)
The German Mouse Clinic (GMC) is a large scale phenotyping center where mouse mutant lines are analyzed in a standardized and comprehensive way. The result is an almost complete picture of the phenotype of a mouse mutant line--a systemic view. At the GMC, expert scientists from various fields of mouse research work in close cooperation with clinicians side(More)
