Regulatory (Foxp3 expression) vs inflammatory (IL17 and IFN-γ of all circulating PBMC. Gates 1+2 represent over 85 % of cells collected in each group. Up to 15 % of the cellevents collected resided outside of these gates, but formed no other major subset of cells. The percentage of all populations (CD3⁺ and CD3⁻) expressing Foxp3 or IL17 and IFN-γ from (a) gate 1 – lymphocytes, (b) gate 2 – monocytes or larger cells, (c) overall PBMC gates 1 and 2. Black circles represent the six patients whose blood was taken at the time of primary CDI, but who later became recurrent.
