In contrast to the differential signaling of BW 828 and 9.3 in resting T cells, the two mAbs exhibited a similar pattern of early signaling events in activated T cells and Jurkat cells ( p56(lck) activation , association of phosphatidylinositol 3-kinase with CD28 ), indicating that the signaling capacity of CD28 changes with activation.
