Figure 4.
Capacity of cytokines to inhibit Fas-independent apoptosis of thymocyte subsets in vitro. Purified CD4+8+ or HSAhiCD4+8− thymocytes from normal B6 mice were cultured overnight either in medium alone (gray bars) or with a mixture of anti-TCR (0.1 μg/ml) and anti-CD28 mAbs (black bars); where indicated, the recombinant cytokines shown were added to the cultures at 100 U/ml. The data show mean percent apoptosis (top panels) and percent difference in (Δ) apoptosis (bottom panels).
