| pubmed-article:549653 | pubmed:abstractText | Synthetic polycations cause a stimulation in the rate of tissue accumulation of colloidal 198Au by the rat visceral yolk sac (at 17.5 days of gestation) and rat peritoneal macrophages cultured in vitro. The mechanism of stimulation has been elucidated in these two cell types by using a dual-substrate technique, and by examining the differential effects of poly(D-lysine) and poly(L-lysine) and of metabolic and cytoskeletal inhibitors. Polycations cause aggregation of colloidal 198Au in the culture medium and increase its affinity for the plasma membrane. In the rat peritoneal macrophage this polycation-colloidal gold complex is pinocytosed, thus enhancing the intracellular accumulation of the radio-labelled substrate. In contrast, the rat visceral yolk sac cannot internalize this complex, and so the substrate accumulates extracellularly. This mechanism of polycation modification affords the opportunity for differential uptake of a substrate into distinct cell types. | lld:pubmed |
