Gene therapy for atherosclerosis and atherosclerosis-related diseases
1A.I. Virtanen Institute and Department of Medicine, University of Kuopio, P.O. Box 1627, FIN-70211 Kuopio, Finland.
Abstract:
Gene therapy for atherosclerosis-related disorders of lipoprotein metabolism is primarily directed to liver and aims at long-lasting correction of familial hypercholesterolemia, lipoprotein / hepatic lipase deficiency, and Apolipoprotein A, B, or E -related diseases. Treatment of complications of atherosclerosis (eg, restenosis, ischemia) requires local gene transfer to arterial wall or ischemic muscle with transient gene expression. Catheter-mediated approach or direct injections have been used in clinical trials for the treatment of restenosis and for the induction of angiogenesis in ischaemic limb and myocardium. Other possible applications of local gene transfer include antithrombotic treatment and stabilization of vulnerable plaques.
Insights
Gene therapy offers potential for atherosclerosis, targeting liver disorders for long-term correction. Local gene transfer aims for transient expression to treat complications like restenosis and ischemia.
Area of Science:
- Cardiovascular Medicine
- Genetics
- Molecular Biology
Background:
- Atherosclerosis involves lipoprotein metabolism disorders.
- Current treatments for atherosclerosis complications are limited.
- Gene therapy presents a novel therapeutic avenue.
Purpose of the Study:
- To explore the applications of gene therapy in treating atherosclerosis and its complications.
- To differentiate between systemic and local gene therapy approaches for cardiovascular diseases.
Main Methods:
- Systemic gene therapy targets liver disorders like familial hypercholesterolemia.
- Local gene transfer is employed for arterial wall or ischemic muscle treatment.
- Catheter-mediated delivery and direct injections are utilized in clinical trials.
Main Results:
- Gene therapy can achieve long-lasting correction of inherited lipoprotein disorders.
- Local gene transfer enables transient expression for treating restenosis and inducing angiogenesis.
- Potential applications include antithrombotic strategies and plaque stabilization.
Conclusions:
- Gene therapy holds promise for both inherited lipoprotein disorders and acute complications of atherosclerosis.
- Differentiated approaches (systemic vs. local) are crucial for specific atherosclerosis-related conditions.
- Further research into local gene transfer could lead to new treatments for ischemic diseases and plaque instability.
