hematopoietic system
• increase in the percentage of lambda expressing B cells in spleen and bone marrow
• the ratio of newly generated to precursor B cells s significantly decreased
• total number of splenic B cells was reduced by 2-fold in spleen
• the number of kappa producing B cells in spleen was reduced dramatically; however the number of lambda producing B cells was increased by more than 5-fold
