Abstract
The purpose of this research is to develop magnetic resonance imaging (MRI) visible immunomodulatory microspheres (IMM-MS) for efficient image guided cancer immunotherapy. IMM-MS composed of recombinant interferon gamma (IFN-γ), iron oxide nanocubes (IONC), and biodegradable poly(lactide-co-glycolide) (PLGA) were successfully prepared via a double-emulsion method. The prepared IMM-MS exhibited a sustained IFN-γ release and highly sensitive MR T2 contrast effects. Finally, in an orthotopic liver tumor VX2 rabbit model, successful hepatic intra-arterial (IA) transcatheter delivery of IMM-MS to liver tumors was confirmed with MR images. The deposition of IMM-MS significantly increased NK-cell infiltration into the liver tumor site.Entities:
