The lupus of NZB/NZW F1 female mice is associated with immune complex glomerulonephritis and premature death. Cyclophosphamide and 15(S)-15 methyl PGE1 therapy halt disease progression. Fluorescein conjugated antibodies were utilized to label specific leukocytes and the subsets were quantitated using a Fluorescence Activated Cell Sorter. Normal outbred CD-1 female mice showed a decrease in absolute T and B cell numbers with age, but the ratio of T and B cells remained essentially constant through 9 months of age. By contrast the NZB/W female mice showed decreased numbers of total lymphocytes relative to CD-1 controls at all ages. Moreover relative to CD-1s, there was a far greater decrease in T cell numbers (7× for NZB/W versus 2× for CD-1) and B cell numbers failed to decrease with age. The characteristic decline in T lymphocyte numbers and relative increase in B cell numbers in NZB/W mice were corrected with cyclophosphamide and PGE1 therapy. However, there was no selective modification of T cell subsets (L3T4+ or Ly2+) with therapy. Our investigation suggests correction of the abnormal T/B cell ratio may be a useful marker of therapeutic activity in NZB/W mice. |
