Core Tip

Core tip: We review the types and functions of regulatory CD4+ T cells (Treg cells) and describe their roles in the pathologies of the inflammatory bowel diseases, i.e., Crohn’s disease and ulcerative colitis. We have paid particular attention to the use of animal models and human studies to elucidate the mechanisms by which Treg cells influence these diseases and have provided an overview of the potential uses of these cells in therapeutic strategies.
