Atherosclerosis is a chronic inflammatory disease of the arteries and the leading cause of death worldwide. Therapeutics that can temper inflammation using the body’s innate mechanisms are powerful complementary strategies to existing treatments. Our research team in collaboration with Prof. Ira Tabas from Columbia University have developed a polymeric nanoparticle using a rapid microfluidic platform enabling the production of small and robust nanoparticles effectively entrapping IL10 protein (an anti-inflammatory cytokine), in a matter of minutes. The nanoparticles also have a targeting ligand for plaque retention and therefore the ability to release IL-10 in a spatiotemporal manner. These findings were recently published in ACS Nano.
