Insights
Exosomes from vascular cells play key roles in atherosclerosis. Engineering these exosomes offers potential for treating cardiovascular disease (CAD) by enhancing their therapeutic capabilities.
Area of Science:
- Cardiovascular Science
- Cell Biology
- Nanomedicine
Background:
- Atherosclerosis, a primary cause of cardiovascular disease (CAD) mortality, involves intercellular communication via exosomes.
- Exosomes secreted by vascular endothelial cells (VECs), vascular smooth muscle cells (VSMCs), immune cells, and platelets mediate this communication.
Purpose of the Study:
- To review exosome biogenesis, uptake, and their roles in atherosclerosis.
- To discuss strategies for enhancing atheroprotective exosomes for therapeutic applications in CAD.
Main Methods:
- Literature review of exosome function in atherosclerosis.
- Analysis of exosome engineering techniques, including drug loading and surface modification.
Main Results:
- Exosomes exhibit both atherogenic and atheroprotective functions depending on their cell of origin.
- Drug loading and surface modification can enhance the therapeutic potential and targeting of atheroprotective exosomes.
Conclusions:
- Exosomes are critical mediators in atherosclerosis, offering therapeutic targets.
- Engineering exosomes presents a promising, yet challenging, avenue for cardiovascular disease treatment.
Abstract:
Cardiovascular disease (CAD) due to atherosclerosis is a major cause of death worldwide. The development of atherosclerosis involves intercellular communication facilitated by exosomes secreted from vascular endothelial cells (VECs), vascular smooth muscle cells (VSMCs), immune cells, and platelets. In this review, we summarize the current understanding of exosome biogenesis and uptake, and discuss atherogenic and atheroprotective functions of exosomes secreted from these cell types. In addition, we examine the potential of enhancing the therapeutic and targeting ability of exosomes exhibiting atheroprotective function by drug loading and surface modification with targeting ligands. We conclude with current challenges associated with exosome engineering for therapeutic use.
