The differences in the lupus activity of MRL/lpr mice among MT, Pred, and FMT groups. a Serum anti-dsDNA autoantibody levels. b Serum ANA autoantibody levels. b Serum urea nitrogen (BUN) levels. d Spleen index. e Percentage of plasma cells in the spleen. f Percentage of GC B cells in the spleen. g The percentage of double negative (DN) T cells in the spleen. MT, the MRL/lpr mice treated with sterile water; Pred, the MRL/lpr mice treated with prednisone; FMT, the MRL/lpr mice treated with fecal microbiota transplantation. “**” represents p < 0.01; “*” represents p < 0.05; “ns” represents no significant difference
