The mechanisms for mutual interactions between microglial cell and Müller cell in ischemic retinopathy / 中华眼底病杂志

ABSTRACT

Ischemic retinopathy,resulting in multiple lesions like microvasculature damage,inflammation and neovascularization,is a major contributor of vision damage.In these pathological changes,retinal glia cannot be ignored in the development of retinopathy.They constitute a highly versatile population that interacts with various cells to maintain homeostasis and limit disease.Therefore,glial activation and gliosis are strikingly ubiquitous responses to almost every form of retinal disease.Both of microglial cells and Müller cells are major intrinsic retinal glial cells and they are in close relationship,which means they can influence each other,make joint action or even become interdependent.They exhibit morphological and functional changes to have an impact on degree of retinal injury through different responses,which mediated by glial cells are important not only for course of disease progression,but also for the maintenance of neuronal and photoreceptor survival.Thus,defining the mechanisms that underlie communications between microglial cells and Miller cells could enable the development of more selective therapeutic targets,with great potential clinical applications.
