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 The CD40 receptor on Müller cells (yellow) is activated in retinas of diabetic mice, presumably by binding to CD40L. CD40 activation triggers phospholipase Cγ1 (PLC) activation, leading to an increase in intracellular calcium (Ca 2+) resulting in release of ATP. CD40 activation also causes Müller cells to express the chemokine CCL2. 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. Muller cells provide nutrition for neural cells.

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. Abstract.

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.

Diabetic retinopathy (DR) is a sight-threatening complication associated with the highly prevalent diabetes disorder. Both the microvascular damage and neurodegeneration detected in the retina caused by chronic hyperglycemia have brought special attention to Müller cells, the major macroglia of the retina that are responsible for retinal homeostasis.

Even though anti-vascular endothelial growth factor (VEGF) interventions represent the therapeutic option for PDR, they are only partially efficacious. In PDR, Müller cells undergo reactive gliosis, produce fluence of junctional complexes between Muller cells and photorecep-tors [29] labelled as External Limiting Membrane (ELM), is the inner most layer. The second hyperreflective layer correlates to the Ellipsoid Zone verity of diabetic retinopathy and decrease in visual acuity.

Nine clinical trials examining the stem cell-based treatment of diabetic retinopathy were registered on ClinicalTrials.gov, which primarily focused on endothelial progenitor cells (NCT01927315), induced pluripotent stem cells (NCT03403699), hematopoietic stem cells (NCT01972438), embryonic stem cells (NCT02749734 and NCT03046407), autologous CD34 + stem cells (NCT03981549), and autologous …

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. Since… 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 Here we investigate the associated cellular and molecular mechanisms underlying mitophagy in retinal cells under diabetic conditions.

Diabetic retinopathy (DR) is the most common complication of diabetes and a leading cause of vision loss worldwide (1). Unfortunately, there are no treatments targeting early stages of the disease prior to the onset of sight-threatening vascular defects such as macular edema or neovascularization. A better understanding of the etiology of DR is needed to identify therapeutic targets to halt Muller cells provide nutrition for neural cells.
