摘要
pH-Sensitive liposomes composed of dioleoylphosphatidylethanolamine and cholesterol hemisuccinate (3:2 mol/mol) were applied in delivery of antisense oligodeoxynucleotides (asODN) into NG 108-15 neuroblastoma and glioma cells. Fluorescently labelled asODN were entrapped in liposomes by a modified freeze-thawing method (20% encapsulation efficiency). The uptake of asODN (free or entrapped in liposomes) by NG 108-15 cells was monitored by fluorescence-activated cell sorting and confocal microscopy. Delivery of asODN was significantly improved when antisense were entrapped in liposomes as compared to free (nonliposomal) asODN. The uptake was dose-dependent and optimum was achieved after 2 h incubation. NeuroReport 11:3117-3121 (C) 2000 Lippincott Williams & Wilkins.
