阿尔茨海默病　阿尔茨海默病的基因疗法有望于今年内进入人体试验阶段。研究者报告在确诊患有阿尔茨海默病后，从病人皮肤上分离出成纤维细胞，使其在实验条件下生长，然后用一个与白血病类疾病有关的病毒将编码神经生长因子（ＮＧＦ）的基因转染到成纤维细胞中，再将这些转染 Alzheimer’s disease gene therapy for Alzheimer’s disease is expected to enter the human test phase this year. Researchers report that after diagnosis of Alzheimer’s disease, fibroblasts are isolated from the patient’s skin and allowed to grow under experimental conditions. A nerve cell line that encodes nerve growth factor (NGF) is then transduced with a virus associated with a leukemic disease, The gene was transfected into fibroblasts, which were then transfected
