Cardiovascular diseases (CVD), and peripheral vascular diseases (PVD), are the leading cause of mortality and morbidity worldwide. Our laboratory is focused on two fronts of our battle toward better treatment strategies of CVD and PVD.
-Basic research directions: Vasculature is primarily constituted by vascular smooth muscle cells (SMC). Past studies have established the essential role of SMC in maintaining the homeostasis and hence healthy state of the circulation system. Under disease challenges such as diabetes or hypertension, these cells will undergo a phenotypic transition, which propels and perpetuates the local lesion development. Therefore, understanding such phenotypic transition holds the key for the development of next-generation cardiovascular medicines. Currently, we have identified the integrated stress (IRS) pathways as one of the most pivotal drivers of the pathophysiologies of vasculature. For example, endoplasmic reticulum (ER) stress (e.g., PERK kinase) and amino acid stress (e.g., GCN2 kinase) have both emerged as promising intervention targets for effective management of post-intervention occlusion, abdominal aortic aneurysm (AAA), and so on.
-Translational research directions: In collaboration with prominent bioengineering laboratories, our cross-disciplinary team has been developing and optimizing innovative drug delivery platforms for highly effective yet safer management of local vascular lesions such as aneurysm, restenosis, etc.
Perivascular local drug delivery: We developed a unique hybrid platform comprised of thermosensitive hydrogel and slow-release nanoparticle. This technology, now named Pericelle, is specifically tailored for vascular surgeons that can be conveniently applied around vessels of interest immediately after the completion of open vascular procedures such as coronary artery bypass graft (CABG) or arteriovenus fistula (AVF) creation. Such application can sustain at least 12-month management of the vessel patency as evidenced in our recent studies.
Endovascular targeted drug delivery: Biomimetic nanomedicine is a highly innovative concept that incorporates cell-derived membrane vesicle coating and conventional nanoparticle technology. Through such biomimetic biointerfacing, we can grant the drug-loaded nanoparticles with unique properties that are intrinsic to the donor cell types. For example, we have successfully developed a platelet-mimetic nanocluster system that behaves just like platelet, such as great biocompatibility, lesion targeting selectivity, and efficient uptake by recipient cells.
