the mitogenically induced il-2 secretion was prompt in t cell cultures from asymptomatic hbsag carriers compared with hb-immune and hb-susceptible donors , and significantly higher after stimulation with high ( 100-1,000 ng/ml ) compared with low ( 0.1-1.0 ng/ml ) concentrations of hbsag , indicating that t lymphocytes from asymptomatic hbsag carriers are mitogenically pre-activated by circulatory hbsag in high concentrations in vivo .
