Interestingly, ΔT1-T0 CD1a+Cd80+ (dendritic cells) and ΔT1-T0 CD163+Cd80+ (M2 macrophages) cells MFI tended to predict pouchitis onset during the follow-up (p = 0.068 and p = 0.062, respectively) (Figure 5b,c); moreover, patients with high increase of CD1a+Cd80+ and CD163+Cd80+ cell MFI levels in the T0–T1 interval experienced pouchitis more frequently and for longer periods (Figure 5d,e). Here, CD1A is linked to pouchitis.
