Således kan Müller-celler vara en kritisk celltyp i den initiala patogenesen av tidig  Retinal blödning bör man mistänka när synen på det mellersta området makuladegeneration, diabetes eller tidigare blodpropp i ögonbotten. This is evident in a disease like diabetic retinopathy where Müller cells contribute to neuronal dysfunction, the production of pro-angiogenic factors leading to neovascularization, the set up of a chronic inflammatory retinal environment, and eventual cell death. One of the most prominent signs that Müller cells are activated in diabetic retinopathy is the increased expression of glial fibrillary acidic protein (GFAP), a common marker of reactive gliosis (Lieth et al., 1998, Mizutani et al., 1998, Rungger-Brändle et al., 2000). Vascular cells may not be the only cells affected by diabetes in the retina. In particular, abnormalities of the b-wave of the electroretinogram in diabetic patients with absent or minimal microangiopathy have pointed to possible dysfunction of Müller cells, the principal glia of the retina. Müller cells are one of the primary glial cell types found in the retina and play a significant role in maintaining retinal function and health.

4 DIABETIC RETINOPATHY FIGURE 1. Anatomy of the eye. Muller cells and astrocytes are the two key glial cell types found in the retina,¨ and they function as the metabolic modulators for neural and vascular compo-nents of the retina (Abbott NJ, 1992). Both cell types regulate ion concentrations, neurotransmitters, and nutrients for neural cells. diabetes, disease modeling, dyslipidemia, iPSC, Muller glial cells, retinopathy, stem cells 1 | INTRODUCTION Diabetic retinopathy (DR) remains a major cause of visual loss in the working-age population in industriali zed countries, and current treatments are not fully satisfactory (Hernandez, Simo-Servat, Bogdanov, & Simo, 2017). 2017-10-01 Diabetic retinopathy (DR) is the leading cause of visual impairment in the working-age population of the Western world.

The hyperfunction of Muller cells with an increasing glial index, which was detected earlier by us in progressing retinal ischemia, was also observed in retinal neovascularization. 2019-11-16 The established regularities of changing functions in Muller glia and in glia-neuron ratios denote the possibility of using the electroretinographic criteria in the diagnosis of lesions in the retina and of early signs of retinal dystrophy in diabetic retinopathy.

These data provide evidence for selective biosynthetic changes of Müller glial cells in diabetes. Because Müller cells produce factors capable of modulating blood flow, vascular permeability, and cell survival, and their processes surround all blood vessels in the retina, a possible role of these cells in the pathogenesis of retinal microangiopathy deserves to be investigated. 2017-10-01 In pathologic conditions such as diabetic retinopathy, Müller cells contribute to neurovascular dysfunction by producing inflammatory and angiogenic factors. 1, 2 In particular, Müller cells are a 2017-02-01 Muller cells provide nutrition for neural cells.

It can be classified clinically into non-proliferative (NPDR) and proliferative (PDR) forms, according to the presence or absence of retinal neovascularization, and it can present with or without macular edema (DME). D iabetic retinopathy is the most frequent complication of diabetes and the leading cause of visual loss and blindness in the adult population of the United States. 1 Although diabetic retinopathy has been traditionally viewed as a disorder of the retinal vasculature, recent evidence indicates that it also affects the glial and neural cells of the retina. 2,3 The principal glial cell of the In diabetic retinopathy, the uptake of glutamate by Muller cells decreases, leading to glutamate toxicity. Also, potassium conductance is decreased in proliferative diabetic retinopathy.

To achieve this aim, this study was designed to quantify GLAST activity in Müller cells that were freshly isolated from normal rats and those made diabetic by injection of streptozotocin. 2018-08-15 In particular, Muller cell loss has been associated with the development of early stage diabetic retinopathy. In the retina, Muller cells are intimately associated with both vasculature and neurons and play a key role in the maintenance of overall retinal homeostasis and function. Diabetic retinopathy (DR) is a chronic, low-grade inflammatory disease. We aimed to investigate the regulatory effects of erythropoietin (EPO) on the inflammatory cytokine production by Muller dence that Müller cells initiate retinal inflammation in the diabetic retina and signal to microglia to elicit their partic-ipation. The study concludes that diabetes triggers retinal neuroinflammation directly through CD40 stimulation on Müller cells and indirectly through ATP release by Müller cells,leadingtostimulationofP2X 2021-01-19 Diabetic retinopathy (DR) is a chronic, low-grade inflammatory disease. We aimed to investigate the regulatory effects of erythropoietin (EPO) on the inflammatory cytokine production by Muller cells under the condition of DR. The expression levels of TNF-alpha, IL-1beta, IL-6 and VEGF in cultured rat Muller cells were enhanced by 1 mM glyoxal.
