Characterization of T and B antigen-binding cells for beta-galactosidase. II. T antigen-binding cells
The results reported in this paper suggest that the specific Z-binding cells of the normal mouse include a large portion of T lymphocytes. Depletion of T cells with anti-theta serum and cortisone indicates that the majority of the ZBC of the thymus, which occur at frequencies of about 150/10(6), are indeed T cells. Similar treatment of spleen cells suggests that approximately half the binding cells in that organ are contributed by the T lymphocyte population. T-and B-enriched populations obtained from the spleen by using differential adherence to nylon wool contained equal numbers of ZBC and bound equivalent amounts of the antigen. Hence, there appears to be a high frequency of T lymphocytes that can be shown to bind beta-galactosidase specifically in both the thymus and spleen of normal mice.
