immune system
abnormal B cell physiology ( J:76770 )
• B cells are constitutively activated
increased B cell proliferation ( J:76770 )
• enhanced proliferative response of splenic B2 cells stimulated with anti IgM
abnormal T cell physiology ( J:76770 )
• T cell proliferation remains normal
abnormal T-helper 2 physiology ( J:76770 )
• enhanced T helper 2 dependent antibody responses
• augmented IgG1 and IgE responses
• increased production of Il-4 and decreased Ifn-gamma
abnormal dendritic cell differentiation ( J:76770 )
• dendritic cells remain immature
increased B-1 B cell number ( J:76770 )
