we propose a model for the role of inducible class ii molecules on endothelium and stromal cells in vivo : the induction of class ii mhc antigens on endothelial cells , locally mediated by activated t cells , enables endothelium to present an immunogenic cell surface structure , comprised of antigen plus self class ii polymorphic determinants , which in turn , serves to recruit additional antigen-specific t cells from the circulation into the site of a developing cell mediated immune response .
