腺病毒载体,最有潜力的心血管疾病治疗载体?

Adenovirus vVector,a Most Potential System for Cardiovascular Disease?

心血管疾病在当今社会仍有很高的死亡率,基因治疗的可行性在不断探索。腺病毒载体可高效实现心血管内基因转移,但其组织特异性和免疫原性限制了其应用。近年来腺病毒载体不断发展,涌现的第三代腺病毒载体成为极有潜力的理想基因治疗转导载体。本文综述腺病毒载体的性质、优点及发展过程,在心血管疾病中的具体应用,总结目前应用中的障碍和改进策略。

Cardiovascular disease is a major cause of morbidity and mortality in the contemporary society. Cardiac gene therapy has already been investigated in clinical studies profoundly. Adenovirus vector could transfer the gene efficiently, but low organ specificity and immuno- genie properties limited its application, With adenovims vector improved in the last few years, the third adenovims vector is probably the most potential vector systems for cardiovascular disease. This review will give a broad overview of the molecular basis of the adenovims vectors, their advantages, the development of increasingly efficient gene transfer approach, and experimental and clinical studies targeting the heart, application barriers and modified strategies.
