Tumor Protective Activity of CD4+ but Not of CD8+ T Cells in DNA-Vaccinated Mice Challenged with bcr-abl-Transformed Cells
Figure 3
Flow cytometry analysis of 12B1 cells for the expression of MHC class II, Fas (CD95) and FasL (CD178), (a) cells treated with anti- MHC class II antibody, (b) cells cultivated in the presence of INF-γ and treated with MHC class II antibody, (c) cells treated with anti-Fas (CD 95) antibody, and (d) cells treated with anti-FasL (CD 178) antibody. Grey histograms indicate cells treated with the respective antibody. Empty histograms represent cells treated with the appropriate isotype controls.
