IV. Stimulation with soluble heterologous anti-delta antibodies. PG - 1-14 AB - Mouse spleen cells were stimulated to proliferate in vitro by soluble affinity-purified heterologous antibodies to mouse delta. Antibodies from goat or rabbit antisera to TEPC 1017, a mouse IgD myeloma protein, were purified on an affinity column of TEPC 1033, a second mouse IgD myeloma protein. Maximum uptake of [3H]thymidine in the range of 60,000 cpm was obtained after 48 hr of culture with anti-delta at concentrations of 50 micrograms/ml. In contrast, the hybridoma 10-4.22 anti-delta was nonmitogenic at similar concentrations. The proliferative response was not impaired upon removal of T cells by treatment with an anti-thymocyte serum (ATS), nor by removal of adherent cells by passage of spleen cells over Sephadex G-10 columns and counter-flow centrifugation. Splenic lymphocytes isolated on the fluorescence activated cell sorter (FACS) with intermediate-to-high amounts of surface IgD (sIgD) were responsive to soluble anti-delta, while IgD-negative cells, or cells with low amounts of sIgD, were unresponsive. Spleen cells from mice less than 4 weeks of age, or from mice carrying the X-linked B cell defect (xid), were unresponsive to anti-delta. These results indicate that anti-delta acts similarly to anti-mu in stimulating a proliferative response by later maturing B cells, which are characterized by a high density of sIgD.
