immune system
• nulls on the 129 background show increased Ag-induced production of Il17 and decreased Il5 production compared to wild-type 129 mice
• in the MOG35-55 induced model of EAE, Mapk3-deficient mice and controls of either background show susceptibility to EAE; knockouts on the 129 background show increased susceptibility compared to 129 control mice
• inflammation is mildly increased in Erk1-deficient mice on the 129 background compared to 129 controls
