FAD-peptide-induced secretion of IFN-γ. PBMC of patients m3 and m4 were stimulated as described in the legend to Fig. 5 (same experiments). SN were taken on day 7 and the amount of IFN-γ quantified. Negative groups had values below the limit of detection (15·6 pg/ml: medium only, addition of the synthetic peptide, 6HDNO or 6HDNO.Cys), positive controls included PHA and SEB (both> 700 pg/ml). Means and standard deviation are given.
