Abstract

Neuronal precursor cells may provide for cell replacement or gene delivery vehicles in neurodegenerative disease therapy. One impediment to treating neuronal diseases is finding ways to introduce genes into neurons effectively. It is shown here that fiber-modified adenovirus vector delivered gene to neuronal precursor as well as differentiated neuronal cells more efficiently than first-generation adenoviral vector. Moreover, fiber-modified adenoviral vector transduced precursor cells retained the potential for differentiation into neurons and glia in vitro. These results show the potential of modified adenoviral vector in the improved gene delivery to neurons in direct gene therapy protocols. In addition it holds promise for the use of genetically manipulated stem cells for the therapy of neuronal diseases.

신정전구세포를 이용한 퇴행성 뇌질환의 세포치료나 유전자치료에서 효율적인 유전자 전달을 목적으로 개량된 아데노바이러스 벡터의 실용 가능성을 쥐의 해마에서 유래된 신정전구세포를 이용하여 조사하였다. 외피단백질을 조작한 개략 아데노바이러스벡터는 분화전과 후의 신정전구세포로 1세대 아데노바이러스 벡터에 비해 6배 정도 유전자를 효율적으로 전달하였다. 또한 바이러스의 감염은 신정전구세포가 신경세포나 신정 아교세포로 분화하는데 영향을 미치는 않았다. 따라서 신정전구세포를 이용한 신정질환의 세포치료나 유전자 치료에서 개량된 아데노바이러스로 유전자를 전달하면 치료의 효율성을 향상시킬 수 있을 것이다.
