MSCs increased monocytic MDSCs in DLNs and peripheral blood in mice with EAU.
One day after EAU induction and MSC IV administration, the increase of IL-10-expressing MHC IIloLy6G−Ly6ChiCD11b+ cells was noted in DLNs and peripheral blood in mice. Also, there were up to 80- and 400-fold increases in iNOS and Arg1, the molecules known to mediate the immunosuppressive functions of MDSCs, in DLNs of the MSC-treated mice.
