A multitude of micro- and nanoparticles have been developed to improve the
delivery of systemically administered pharmaceuticals, which are subject to a
number of biological barriers that limit their optimal biodistribution.
Bioinspired drug-delivery carriers formulated by bottom-up or top-down strategies
have emerged as an alternative approach to evade the mononuclear phagocytic
system and facilitate transport across the endothelial vessel wall. Here, we
describe a method that leverages the advantages of bottom-up and top-down
strategies to incorporate proteins derived from the leukocyte plasma membrane
into lipid nanoparticles. The resulting proteolipid vesicles-which we refer to as
leukosomes-retained the versatility and physicochemical properties typical of
liposomal formulations, preferentially targeted inflamed vasculature, enabled the
selective and effective delivery of dexamethasone to inflamed tissues, and
reduced phlogosis in a localized model of inflammation.
