♂ phenotype observed in males
N normal phenotype
immune system
increased susceptibility to experimental autoimmune encephalomyelitis ( J:112657 )
• mice have a significantly more severe form of EAE with an earlier onset than controls after induction with MOG peptide
• mean day of onset is 11.5 compared to 13.9 for wild-type controls
• mean severity score is 4.0 versus 3.0 in wild-type controls
• memory T cells isolated from mice 10 days after disease induction proliferate more and produce more TH-1 cytokines and less IL-10

abnormal T cell number ( J:113083 )
• mucosal-associated invariant T cells (MAIT) that express the canonical mVa19-Ja33 TCR rearrangement and are typically found in the gut lamina propia are virtually absent in these mice
abnormal B cell physiology ( J:113083 )
• preliminary results indicate a reduction in the number of IgA producing B cells in the gut
