hematopoietic system

decreased germinal center B cell number ( J:157915 )

• 9 days after immunization with a T cell dependent antigen, 4-hydroxy-3-nitrophenyl acetyl(NP) -OVA, mice have reduced numbers of B220+ IgD^lo Fas^hi GL-7+ germinal center B cells

decreased CD4-positive, alpha-beta T cell number ( J:157915 )

• 7-9 days after immunization, there is a decrease in CD4+ T cells expressing Tfh cell markers

abnormal long lived plasma cell morphology ( J:157915 )

• fewer 4-hydroxy-3-nitrophenyl acetyl(NP)-OVA specific antibody secreting cells in the bone marrow 30 days postimmunization

decreased spleen germinal center size ( J:157915 )

• 9 days after immunization with a T cell dependent antigen, 4-hydroxy-3-nitrophenyl acetyl(NP) -OVA, mice have fewer germinal center structures that are also reduced in size

decreased IgG level ( J:157915 )

• high-affinity 4-hydroxy-3-nitrophenyl acetyl(NP) specific antibodies are at lower titers than in wild-type mice, 30 days postimmunization

abnormal CD4-positive, alpha-beta T cell physiology ( J:157915 )

• after immunization with the T-dependent antigen 4-hydroxy-3-nitrophenyl acetyl(NP) fewer cells produce IL21
