Research Projects

Reactive oxygen species (ROS) play an important role in the pathogenesis of age-related diseases such as diabetes.  ROS such as hydrogen peroxide and superoxide are overproduced by activated macrophages.  As scavengers of ROS, enzymatic proteins such as catalase and superoxide dismutase (SOD) have a great therapeutic potential; however, in vivo application is limited especially when they are orally administered.  Although, the oral route is the most convenient for drug administration, therapeutic proteins are easily degraded in vivo by the harsh conditions of gastrointestinal (GI) tract.  Zein nanoparticles can protect therapeutic proteins, catalase and SOD, from the harsh conditions of GI tract.  Folate-conjugated catalase or SOD in zein nanoparticles can target the activated macrophages and scavenge the ROS generated by macrophages in vitro.

In atherosclerosis, activated endothelial cells (EC) generate more reactive oxygen species (ROS) and inflammatory mediators that recruit monocytes to the vessel wall. Novel monocyte-based drug delivery systems encapsulating either catalase or tempol/tempo will scavenge ROS efficiently due to its target specificity to damaged EC.

Acute liver failure (ALF) is a major cause of death in the world and effective treatments are greatly needed.  Kupffer cells, resident macrophages of the liver, secrete inflammatory cytokines such as TNF-α during ALF which cause massive necrosis of hepatocytes and small interfering RNA (siRNA) that can inhibit Kupffer cell activation have a great therapeutic potential.  In this report, we present that a polyketal microparticles deliver a TNF-α siRNA to macrophages and reduce the inflammatory response associated with ALF in vitro and in vivo, where free siRNA had no therapeutic effects due to its poor stability and inefficient cellular uptake.  Polyketal nanoparticles have the properties needed for treating acute liver failure such as targeting liver macrophages, fast drug release, low toxicity, and a long shelf life for clinical trials.
