摘要
1型神经纤维瘤病[NF1]是一种多器官常染色体显性遗传疾病。NF1以其各种临床表现而闻名,包括咖啡-金斑、Lisch结节、骨畸形和神经纤维瘤。然而,对于NF1尚无有效的治疗方法。目前治疗的目的是缓解NF1的临床症状,但没有治愈疾病。通过改变致病基因,基因治疗在核苷酸水平上调控细胞活性。本文综述了神经纤维蛋白结构域的结构和功能,包括间隙相关结构域[GRD]、富含半胱氨酸丝氨酸结构域[CSRD]、富含亮氨酸结构域[LRD]和c端结构域[CTD],分别改变了下游通路。通过转染这些区域的分离序列,研究人员可以部分恢复神经纤维瘤细胞系的正常细胞功能。此外,重组转基因序列可以被设计成编码被截断的蛋白质,这是功能和容易包装成病毒载体。此外,基因治疗的治疗效果还受载体选择、转基因包装策略和给药等多种因素的影响。本文总结了多种NF1基因治疗策略,并从多个角度探讨其可行性。不同的蛋白结构域改变了神经纤维蛋白的功能和下游通路。
