Activated Mφ express different levels of MHC Class II and B7 costimulatory molecules. Flow cytometry profiles for (A) MHC Class II and (B) B7.2 (CD86) on activated Mφ 24 h after stimulation. Mφ were primed with IFN-γ and stimulated with LPS (Ca-Mφ) or LPS + IC (Mφ-II), primed with IL-4 (AA-Mφ) or left unstimulated. Mφ were stained with FITC-conjugated α-I-Ad or PE-conjugated α-CD86. Changes in expression are assessed by comparison against unstimulated Mφ. Figures are representative of at least three independent experiments.
