immune system

decreased T cell number ( J:125719 )

• 2 fold decrease in the number of T cells in the spleen

abnormal B cell morphology ( J:125719 )

decreased immature B cell number ( J:125719 )

• less than 1 percent of bone marrow cells are immature B cells ( normal is about 8%)

increased pro-B cell number ( J:125719 )

• about 2 fold increase due to block in development from pro-B cell to pre-B cell

decreased mature B cell number ( J:125719 )

• 100 fold decrease in the number of B cells in the spleen
