Polystyrene nanospheres (NS) were found to be efficiently taken up by murine antigen-presenting cells (APC), especially bone marrow-derived dendritic cells (DC), in vitro and in vivo. The efficiency of NS uptake was not affected by the maturation state of DC. Both immature and mature DC had similar ability to take up NS in a dose- and time-dependent manner. Uptake and intracellular localization of NS was clearly demonstrated by confocal laser microscopy, using NS with fluorescence. DC could efficiently take up ovalbumin (OVA), when loaded on the surface of NS (OVA-NS). Consequently, OVA-NS-pulsed DC activated antigen-specific interferon (IFN)-gamma-producing T cells much more strongly than OVA-pulsed DC in vitro. These results suggest that NS can be used as an efficient antigen delivery system to DC for a variety of vaccines, such as an anti-human immunodeficiency virus type 1 vaccine.
