Regulatory T cells (Treg) are supportive to cancer development in most tissues, but their role in colitis-associated colon cancer (CAC) remains unclear. In this study, we investigated the role of CD4(+)Foxp3(+) Treg in a mouse model of CAC and in patients with colon cancer. These Treg were increased strongly in number in a mouse model of CAC and in the(More)
BACKGROUND In contrast to intestinal CD4(+) regulatory T cells (T(regs)), the generation and function of immunomodulatory intestinal CD8(+) T cells is less well defined. To dissect the immunologic mechanisms of CD8(+) T cell function in the mucosa, reactivity against hemagglutinin (HA) expressed in intestinal epithelial cells of mice bearing a MHC(More)
Pr ecis: This study suggests a route through which senescence can be defeated to blunt a fail-safe mechanism that can restrain the powerful oncogenic effects of deregulated MYC, which underpins the malignant development of most human tumors. Pr ecis: These findings encourage further evaluation of an innate immune regulator as a noninvasive biomarker that(More)
