Muller cells provide nutrition for neural cells. We studied the structure and ultrastructure of Muller cells in the retina of thirty 3-month old Wistar rats; divided equally into 3 groups: normal rats, alloxan diabetic rats and treated alloxan diabetic rats. 1 and 12 months after induction of diabetes.

Diabetic retinopathy is the leading cause of blindness in the working-age population in Western countries [].The early stages of this devastating disease are characterized by high-glucose (HG)-mediated microvascular changes [2,3,4] as well as glial changes [5,6,7,8,9] in the retina, leading to loss of retinal endothelial cells, pericytes, and Müller glial cells.

To evaluate Müller cells as a potential source of fibrocontractive cells in proliferative diabetic retinopathy. METHODS. Temporal changes in glial fibrillary acidic protein (GFAP), vimentin, glutamine synthetase, and alpha smooth muscle actin (αSMA) expression in cultures of freshly isolated porcine Müller cells were evaluated by indirect immunofluorescence and Western blotting. - "Müller Cell–Microglia Cross Talk Drives Neuroinflammation in Diabetic Retinopathy" Figure 1Proposed role of CD40 and P2X7 receptors in diabetic retinal neuroinflammation.

Considerable evidence is emerging that indicates that retinal neurons are also altered during diabetes.

Figure 1: SD OCT macular cube showing EZ. a: Grade 0: intact EZ b: Grade 1: focal disruption (localized, subfoveal EZ disruption) Muller cell reactivity during diabetic retinopathy [ 2005 - 2007 ] Also known as: Glial cells in diabetes Funded by National Health and Medical Research Council Managed by University of Melbourne 2020-10-01 · Diabetic retinopathy (DR) is the most common microvascular complication in diabetic patients and the leading global cause of vision loss in working middle-aged adults [1, 2]. 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.

Hypoxic retinal Muller cells promote vascular permeability by HIF-1-dependent up-regulation of angiopoietin-like 4.

We studied the structure and ultrastructure of Muller cells in the retina of thirty 3-month old Wistar rats; divided equally into 3 groups: normal rats, alloxan diabetic rats and treated alloxan diabetic rats. 1 and 12 months after induction of diabetes. Fluorescence angiography and electroretinography were dynamically made for 1-1.5 years in 18 patients with preproliferative diabetic retinopathy.

For this, we maintained a rat Müller cell line (rMC1) under high-glucose (25 mM, HG) or low-glucose (5.5 mM, LG) condition for 5 days. Our data reveal that HG upregulates TXNIP in the cytosol as well as in the MT. Fluorescence angiography and electroretinography were dynamically made for 1-1.5 years in 18 patients with preproliferative diabetic retinopathy. 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.

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).

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. Recent studies suggest that abnormal function in Müller glial cells plays an important role in the pathogenesis of diabetic retinopathy.

Recent studies suggest that abnormal function in Müller glial cells plays an important role in the pathogenesis of diabetic retinopathy. This is associated with the selective accumulation of the acrolein-derived advanced lipoxidation end-product, Nε-(3-formyl-3,4-dehydropiperidino)lysine (FDP-lysine), on Müller cell proteins.
