We have previously reported that non-T, non-B 'null' cells increase with age in New Zealand Black (NZB) mice resulting in splenomegaly. Using a panel of monoclonal antibodies recognizing lineage-specific cell surface antigens we demonstrate four distinct subsets within this null cell compartment: (1) undifferentiated; (2) T lineage with undetectable Thy-1.2; (3) myeloid/erythroid; and (4) a pre-B/plasma cell type. All four subsets also occur in non-autoimmune mice. The frequency of these populations are similar in the young mice of all the strains examined, although the total number of null cells is higher in NZB. The elevation of null cells in young NZB mice is controlled by a single dominant gene in the genetic cross with New Zealand White (NZW) mice and does not appear closely related to the subsequent development of autoimmune disease. The proportion of myeloid/erythroid null cells increases with age in NZB as splenomegaly develops. |
