简介
Hyaluronic acid-ceramide (HA-CE)-based self-assembled nanoparticles were developed for intravenous docetaxel (DCT) delivery. In this study, physicochemical properties, cellular uptake efficiency, and in vivo targeting capability of the nanoparticles developed were investigated. DCT-loaded nanoparticles composed of HA-CE and Pluronic 85 (P85) with a mean diameter of 110–140nm were prepared and their morphological shapes were assessed using transmission electron microscopy (TEM). DCT release from nanoparticle was enhanced with increasing P85 concentrations in our in vitro model. Blank nanoparticles exhibited low cytotoxicity in U87-MG, MCF-7 and MCF-7/ADR cell lines. From cellular uptake studies, the nanoparticles developed enhanced the intracellular DCT uptake in the CD44-overexpressing cell line (MCF-7). The nanoparticles were shown to be taken up by the HA–CD44 interaction …
