Tumor antigen and MHC expression in glioma cells for immunotherapeutic interventions

Figure 3 The percentage of cells staining positive for components of the major histocompatibility complex machinery as well as the immune-recognition-enhancing molecule ICAM (CD54) was assessed by flow cytometry. The results are depicted in the diagram with a white box representing staining in less than 10% of cells, a grey box representing 10%-40% cells positive and a black box in case of more than 40% positive cells. Values with and without the 48 h interferon gamma pretreatment (200 IU/mL) are given. IFN: Interferon.
