Effect of therapy on CD64 fluorescence intensity. (a) Expression of MX1 in PBMCs (measured with real-time PCR) and (b) surface expression of CD64 on monocytes (measured with flow cytometry) in four patients before (day 0) and after (day 3) therapy with high-dose methylprednisolone (1 g IV daily for 3 days). Differences were analyzed by using Student's paired t test.
