Vectors employed for malignant glioma gene therapy / 国际肿瘤学杂志

ABSTRACT

The vectors play an important role in gene therapy by transporting the therapy genes into target tumor cells. At present there are mainly two kinds of gene vectors, including biological and non-biological vectors. Biological vectors, including virus, bacteria and stem cells, have good target activity and can efficiently delivery the genes into target tumor cells, but have potential genetic hazards.However, non-biological vectors, including liposomes and nanoparticles, can be simplely prepared with high genetic safety, but they can not transport the genes efficiently. Therefore, establishing safe and effective malignant glioma gene treatment system and finding gene vectors with good target activity become the research focus.
