Fig. 8. DNA synthesis by GC and resting B cells cultured with irradiated and ECDI-treated CD32-L cells. GC B cells (A) or resting B cells (B) were cultured with CM (□), IL-4 (20 ng/mL) (▨), or a combination of IL-10+IL-7+IL-4 (▪) with or without CD40 MoAb, G28-5. Cultures contained CD32-L cells that had been irradiated (as in Figs 1 through 7) or fixed with ECDI. [3H]thymidine uptake was measured after 7 days. Data are means ± SEM. Values for CD32-L cells alone (∼8,000 cpm) have been subtracted.
