Figure S3. Brefeldin A treatment does not prevent suppression of cord T-cell cytokine production resulting from exposure to invariant natural killer T cells and monocytes.

Isolated CD4⁺ cord blood T cells were cultured for 5 d with autologous monocytes alone, or with autologous monocytes and invariant natural killer T cells. Where indicated, the monocytes were pretreated with brefeldin A (BfA) or vehicle (veh) before being added to the co-cultures.
