title: Equal distribution of T-lymphocyte subpopulations in thymus and spleen cells of NZB and BALB/c mice.
abstract: NZB mice develop an autoimmune disease of unknown etiology. Since the detection of immunoregulatory T-cells it has been speculated that disbalances of these cells may be important in the course of the NZB disease. By utilization of monoclonal antibody defining immunoregulatory Lyt subsets and a FACS IV system we investigated whether differences in the number and/or marker densities of given subsets exist between NZB and the normal reference strain BALB/c. Newborn animals and animals up to 60 weeks of age were tested. No significant difference in the percentages nor in the marker densities of theta+, Lyt 1+, and Lyt 2+ cells was observed at any age or sex, neither in spleen nor in thymus. It is concluded the autoimmune disease of NZB is not influenced by the parameters investigated.
