Transfer of MHC class II from APC to Tcells. BLS-CD8 Tcells were incubated with M35-EBV cells (at a 1:1 ratio) for 3 h and stained for CD8 (red) and HLA-DR (green) as described in Methods. (A) Control BLS-CD8 Tcells not incubated with APC. (B) Control M35-EBV cells not incubated with T cells. (C and D) Two representative examples of cells from mixtures of BLS-CD8 T cells with M35-EBV cells.
