Altered T-Cell Balance in Lymphoid Organs of a Mouse Model of Colorectal Cancer.

ABSTRACT: The adenomatous polyposis coli (APC) gene is a known tumor suppressor gene, and mice with mutations in Apc (Apc^Min/+) spontaneously form multiple intestinal neoplasms. In this model of human colorectal cancer (CRC), it has been reported that CD4⁺ T-cell-derived interleukin 17 (IL-17) promotes intestinal tumor development, but it is not known if the Apc mutation actually directly alters T-cell function and subsequently tumor immunosurveillance. To investigate the Apc^Min/+ mutation on T-cell function, flow cytometric, histochemical, and immunofluorescent studies on both wild-type (Apc^+/+) and Apc^Min/+ mice were performed. We identified decreased levels of interferon gamma (IFN-γ⁺)IL-17⁺ double-positive CD4⁺
