제목 Light/ROS-responsive Nanovesicles for Anticancer and Anti-inflammation Therapy
초록 External or internal stimuli-responsive drug delivery systems have been of great interest in that drug molecules are to be released to the site of a disease in a controlled manner, thereby improving efficacy but minimizing toxicity. Here we report a dual light/ROS stimuli-responsive bilirubin nanovesicles (BNVs) for potential anticancer and anti-inflammation therapy. Bilirubin is a final metabolite of heme and functions as a potent antioxidant by scavenging ROS in our body. More interestingly, bilirubin can undergo photo-mediated isomerization to more water-soluble compounds. To use bilirubin for biomedical applications, it was first converted to pegylated bilirubin, which undergoes self-assembly to yield uniform nanovesicles with size of ~120 nm. In this lecture, preparation, characterization, and stimuli-induced disruption behavior of BNVs will be presented. Furthermore, as proof-of-concept, therapeutic efficacy of BNVs on a mouse colitis model will be also presented.
