immune system
increased regulatory T cell number ( J:123547 )
• Foxp3+ regulatory T cells are increased 2-fold relative to wild-type mice
• the numbers of regulatory T cells is increased in the peripheral and mesenteric lymph nodes, spleens and among the lamina propria mononuclear cell infiltrate of the colon
• proliferation of Foxp3+ cells and CD4+CD8+Foxp3- cells is increased in association with the development of colitis
