Although granzyme B production at baseline was below 20 per 106 SFCs, when measurable, PBMC from RU486 treated patients produced a greater number of granzyme B SFCs in response to measles and influenza A whole lysate, and FEC peptide pool measured 72 h post RU486 (Figure 6F; Figure S3 in Supplementary Material). This evidence concerns the gene GZMB and measles.
