Evaluation of Histidine–Octamer-Modified Hyaluronic Acid as a Cytosolic Drug Delivery Material via CD44-Mediated Cellular Uptake and Endosomal Escape
Background: Although intracellular delivery via endocytosis is a promising strategy for drugs acting in the cytosol or nucleus, many macromolecular therapeutics remain trapped within endosomal/lysosomal compartments, limiting efficient cytosolic delivery. In this study, we designed a novel functional hyaluronic acid (H...
