神经元-胶质细胞共生体系对神经营养因子活性影响的研究现状

视网膜色素变性的病理特点是感光细胞和视网膜色素上皮细胞结构和功能的进行性丧失。神经营养因子对其保护作用越来越受到关注。脑源性神经营养因子、睫状神经营养因子和胶质细胞源性神经营养因子可通过直接和间接保护通路影响感光细胞活性。而神经元-胶质细胞共生体系介导的对感光细胞活性的间接保护作用更为重要。胶质细胞介导的神经营养因子治疗相关眼病取得了部分进展，这将为延缓视网膜色素变性病情发展提供一种新的有效手段。

Research status of neuronal-glial cell symbiosis system on neurotrophic factor activity

Retinitis pigmentosa is characterized by the progressive loss of the structure and function of photoreceptors and retinal pigment epithelium.Neurotrophic factors are more and more concerned.Brain-derived neurotrophic factors，ciliary neurotrophic factors and glial cell line-derived neurotrophic factors can affect photoreceptor activity through direct and indirect protection pathways.Neuronal-glial cell symbiosis system mediated by the indirect protection of photoreceptors is more important.Studies on glial cell-mediated neurotrophic factors for the treatment of related eye disease have made some progress，which will provide a new and effective methodsto delay the development of RP.
