摘要
We have used limiting dilution analysis to compare the frequency of dendritic cells (DC) which present endogenous alloantigens with that which present an exogenous protein antigen to T lymphocytes. Spleen DC present alloantigens or ovalbumin to primed T lymphocytes with equal frequency, showing that DC are equipotent for presenting endogenous and exogenous antigens. Also, antigen-presenting cell (APC) frequencies among DC were compared with other APC populations. DC were enriched about 1000-fold for APC compared to unfractionated spleen cells. © 1990.
