Example 1
WT C57BL/6 CD45.2 Thy1.2 and BALB/c mice were obtained from Charles Rivers, France. WT C57BL/6 CD45.1, Rag2−/−, Cxcr3−/−, Ifnar1−/−, Dpp4−/−, Dpp4−/−, Cxcl10−/−, Ccr5−/−, Pmel-1 Thy-1.1+Thy-1.1+, OT1 and FVB-Tg(CAG-luc) mice were bred in our mouse facility. Male Pmel-1 Thy-1.1+Thy-1.1+ mice were crossed with female Cxcr3−/− Thy-1.2+Thy-1.2+, mice to obtain first generation males that were Pmel-1 Cxcr3−/− Thy-1.1+Thy-1.2+. Mice used were 7-12 weeks old. For inhibition of DPP4 activity in vivo, mice were fed with chow (SAFE) formulated to contain 1.1% Sitagliptin (trade name Januvia, Merck). Sitagliptin food was administrated to mice before treatments, unless stated differently in the figure legend. Mice were maintained in a specific pathogen free facility and all experimental protocols were approved by the Comité d'Ethique pour l'Expérimentation Animate (The ethics committee for animal experimentation) Paris.
