Previous reports have suggested the CD28 stimulation contributes to the activation of the IL-2 promoter by up-regulating the activity of several transcription factors , including AP-1 and nuclear factor-kappaB ( NF-kappaB )/ Rel family members as well as an uncharacterized transcription factor called CD28 response complex.
