A Novel Probiotic Mixture Exerts a Therapeutic Effect on Experimental Autoimmune Encephalomyelitis Mediated by IL-10 Producing Regulatory T Cells
Figure 6
Probiotic-induced Treg cells suppress EAE in an IL-10-dependent fashion.
Naïve C57BL/6 wild type (WT) or IL-10-KO mice were treated with either the probiotic Lacto-mix or saline (control) during 14 days. MLN cells were isolated from these animals and administered intravenously into recipient mice which were immunized for EAE 24 h later. (A) EAE development in recipient mice after adoptive cell transfer of total MLN cells (isolated from mice treated with either saline or Lacto-mix), MLNs (isolated from WT mice treated with Lacto-mix) depleted for CD4+CD25+ cells, isolated CD4+CD25+ cells (from MLNs of Lacto-mix treated WT mice), isolated CD4+CD25+ cells (from MLNs of Lacto-mix treated IL-10 KO mice) (n = 3−5). (B) Serum levels of IL-10 were measured by ELISA in plasma obtained from recipient animals at 28 days after cell transfer. Data are representative of two experiments. Each bar represents mean ± SEM of three samples per group. * represents a p-value ≤0,05 and ** a p-value ≤0,01.
