To validate the effect of TSLP on the early phase of colitis, we performed an acute inflammation followed by a recovery phase on groups of mice treated with LL-WT, LL-TSLP and a group named LL-TSLP early phase, corresponding to an oral administration of LL-TSLP from D7 to D4 followed by oral administration of LL-WT from D5 to D12 (Fig. 5a). The gene discussed is TSLP; the disease is colitis.
