Expression of members of the TNF-R superfamily. The transformed T-cell clone ES-BP8T (top), the native T-cell clone ES-BP8 (middle), and peripheral blood mononuclear cells that had been activated 6 days before with concanavalin A (bottom) were stained for the expression of TNF-RI, CD95, TRAMP, TNF-RII, and CD30. The open graph represents the negative control, and the solid graph represents the specific staining.
