Title: Autoantigen microarrays of NZM2328 lupus mice treated with induced CD4+ regulatory T cells or natural CD4+ regulatory T cells

description:
Foxp3+ regulatory T cells (Treg), playing a crucial role in the maintenance of immune tolerance and prevention of autoimmune diseases, consist of thymus-derived naturally-occurring CD4+Foxp3+ Treg cells (nTreg) and another CD4+Foxp3+ Treg cells that can be induced ex vivo with TGF-β (iTreg). Although both Treg subsets share similar phenotypes and functional characteristics, they also have potential biologic differences on their biology. However, the role of iTreg in regulating B cells of lupus disease mice remains unclear so far. The lupus-prone New Zealand Mixed 2328 (NZM2328) mouse, a recombinant inbred strain that originated from the crosses among New Zealand Black and New Zealand White mice and their progenies also develops Lupus Glomerulonephritis. NZM2328 mice develop autoantibodies and glomerulonephritis with female predominance similarly to humans with systemic lupus erythematosus. The lupus disease onset is usually around 3-4 months age. In our experiments, iTreg induced from NZM2328 lupus-prone mice (10-12 weeks old) and nTreg sorted from the thymus of 10-12 weeks old NZM2328 lupus-prone mice were adoptively transferred into old NZM2328 mice (>4 months age) with established lupus for 32 days. Totally, there were three groups including NZM2328 mice as model (receive PBS), NZM2328 mice received iTreg, and NZM2328 received nTreg. The serum IgG and IgM autoantibody were detected by autoantibodies microarrays (UTSW Medical Center Autoantigen Array) at days 0, 14, 32 after cell transfer. Our results demonstrated that adoptive transfer of iTreg had a superior effect than nTreg subset on suppressing lupus B cell responses in vivo.
