mortality/aging
N
• born in expected numbers

growth/size/body
N
• mice are developmentally normal at birth
• body weights are normal and mice remain healthy past 1 year of age

immune system
N
• primary lymphoid follicles form normally
• response to T cell independent antigens is normal
• considerably fewer follicular helper T cells both before and after immunization
• primary lymphoid follicles form normally but no germinal centers are found in un-immunized mice
• fewer germinal centers found after immunization than in controls
• B cells almost absent both before and 10 days after immunization
• germinal centers also lost in Peyer's patches
• early low affinity response to T cell dependent antigens is normal
• later higher affinity responses are reduced
• lower proliferation of germinal center B cells
• cell arrest in the G1 stage
• higher apoptosis rate
