immune system

abnormal B cell differentiation ( J:158402 )

• mice exhibit decreased B and pre-B cells and an increase in pro-B cells compared with wild-type mice indicating impaired B cell development

• however, V(D)J recombination is normal

increased pro-B cell number ( J:158402 )

• 3- to 5-fold in the bone marrow

decreased B cell number ( J:158402 )

• 4-fold decrease in B220+ cells in the bone marrow

• IgM+ B cells are virtually absent from the bone marrow

• 5-fold in the spleen

decreased pre-B cell number ( J:158402 )

• 2.5-fold in the bone marrow
