increased B cell number ( J:146538 )
• in the peripheral blood
decreased lymphocyte cell number ( J:146538 )
• mice exhibit T cell lymphopenia
decreased CD4-positive, alpha-beta T cell number ( J:146538 )
• CD4+ T cells are reduced in the spleens, lymph nodes, and peripheral blood mononuclear cells compared to in wild-type mice
• however, thymic CD4+ counts are normal
