Prevention of T-cell anergy by exogenous IL-2 in the primary culture.
T cells (1 × 106/mL) from 8 patients were cultured following the same procedure as that described in Figure 2 except that the primary culture was performed in the presence (▪) or the absence (■) of exogenous IL-2 (10 U/mL). Proliferation on rechallenge with platelets was measured and shown as [3H]thymidine incorporation (mean ± SD cpm).
