decreased susceptibility to experimental autoimmune encephalomyelitis ( J:64763 )
• following treatment with MOG, Freund's adjuvant and pertussis toxin, 30% of mice are completely resistant to the development of experimental autoimmune encephalomyelitis and the remaining mice exhibit reduced disease severity compared to similarly treated heterozygotes used as a control
• mice immunized with MOG exhibit reduced accumulation of leukocytes, macrophages and activated microglial cells compared to in similarly treated heterozygotes used as a control
• Background Sensitivity: female mice are somewhat more susceptible to development of experimental autoimmune encephalomyelitis than male mice likely due to the genetic background
