SMCs lack key costimulatory molecules. Representative flow cytometry histograms and relative graph showing the effect of IFN-γ (100 ng/mL) on costimulatory/adhesion molecules expression in murine SMCs. Red empty histograms: isotype control; gray filled histograms or white columns: unstimulated SMCs; black empty histograms or black columns: IFN-γ-stimulated SMCs. Results are expressed as mean ± SEM from three separate experiments run in triplicate. *P < 0.05, **P < 0.01, and ***P < 0.001 versus unstimulated cells.
