Adenomatous polyposis coli (APC) functions are involved in the heterotypic interactions occurring between intestinal epithelial cells (IECs) and intra-epithelial lymphocytes (IELs). These interactions may be of interest in cancer prevention, since recent data provide evidence for lymphocyte mediated immunosurveillance of epithelial cancers. The present study attempts to determine if APC inactivation induces changes in the cross-talk between IEC and large intestine IEL (LI-IEL) through intercellular adhesion molecule (ICAM-1)/leukocyte function-associated (LFA-1) interactions. Mouse Apc+/+ and Apc+/ Min colonocytes were co-cultivated with LI-IEL. When co-cultured with LI-IEL Apc+/ Min IEC but not Apc+/+ IEC expressed high levels of ICAM-1. The presence of ICAM-1 was linked to TNFα production in both co-cultures and TNFR expression only in co-cultivated Apc+/ Min IEC. Finally, butyrate enhanced the expression of ICAM-1 in Apc+/ Min IEC co-cultured with LI-IEL, and the secretion of TNFα by both types of co-cultures. These events could participate in determining the Apc+/ Min IEC immunogenicity under different in vivo conditions.
