Abstract
Muller cells are the major glial cells spanning the entire layer of the retina and maintaining retinal structure. Under pathological conditions, Muller cells are involved in retinal angiogenesis, a process of growing new blood vessels from pre-existing capillaries. In response to hypoxia, high glucose, and inflammation conditions, multiple signaling pathways are activated in Muller cells, followed by the increased production of proangiogenic factors including vascular endothelial growth factor, basic fibroblast growth factor, matrix metalloproteinases, Netrin-4, and angiopoietin-like 4. Expression of antiangiogenic factors is also downregulated in Muller cells. Besides, proliferation and dedifferentiation of Muller cells facilitates retinal angiogenesis. In this review, we summarized molecular mechanisms of Muller cells-related retinal angiogenesis. The potential of Muller cells as a therapeutic target for retinal angiogenesis was also discussed.

: Photoreceptor cell death is the ultimate cause of irreversible vision loss in retinal detachment (RD). The present study aimed to investigate the retinal changes in a case of long-standing traumatic RD in a young patient. The RD-induced atrophic globe was examined following enucleation. A control eye acquired from a deceased donor (normal histology; age- and sex-matched) was evaluated correspondingly. Frozen sections of retina tissue were assessed by immunofluorescence staining. The atrophic r...

Abstract Recent study has showed that Ginsenoside Rg1, the mian active compound of Panax ginseng, could ameliorate oxidative stress and myocardial apoptosis in diabetes mellitus. However, the roles and mechanisms of Rg1 in proliferative diabetic retinopathy (PDR) are still unclear. In the present study, we aimed to investigate the effects of Rg1 on mesenchymal activation of high-glucose (HG) cultured muller cells. High glucose conditions up-regulate MMP-2, MMP-9 and down-regulate TIMP-2, and pro...

BACKGROUND: Matrix metalloproteinases (MMPs) are zinc- or calcium-dependent proteinases involved in normal maintenance of extracellular matrix. When elevated, they contribute to the tissue destruction seen in periodontal disease. Recently, we found that human beta defensin 3 (HBD3), a cationic antimicrobial peptide, alters chemokine and proinflammatory cytokine responses in human myeloid dendritic cells exposed to Porphyromonas gingivalis hemagglutinin B (HagB). In this study, the hypotheses tha...

Abstract Diabetes mellitus leads to oxidative stress and contractile dysfunction in the heart. Although several rationales have been speculated, the precise mechanism behind diabetic cardiomyopathy remains elusive. This study was designed to assess the role of inhibition of advanced glycation endproducts (AGE) in streptozotocin (STZ)-induced diabetic cardiac dysfunction. Cardiac contractile function was assessed in normal C57BL/6 and STZ (200 mg/kg, single injection and maintained for 2 wks)-ind...

Oxidative stress is a causal factor in the development of diabetic retinopathy; however, clinically relevant strategies to treat the disease by augmenting antioxidant defense mechanisms have not been fully explored. We hypothesized that boosting nuclear factor erythroid-2-related factor 2 (Nrf2) antioxidant capacity with the novel Nrf2 activator dh404, would protect the retina in diabetes including vision-threatening breakdown of the blood-retinal barrier (BRB) and associated damage to macroglia...

Abstract Aims Gambogic acid (GA) is one of active components of Chinese medicine gamboges resin. Diabetic retinopathy (DR) is a most serious microvascular complication of diabetes and also the leading cause of blindness. The aim of this study is to evaluate the beneficial effect of GA on diabetes-induced retinal angiogenesis and further explore the potential mechanisms. Material and methods High glucose (HG)-treated RF/6A cells and STZ-induced diabetic mice were used as in vitro and in vivo mode...

Within the mammalian retina, both Muller glia and astrocytes display reactivity in response to many forms of retinal injury and disease in a process termed gliosis. Reactive gliosis is a complex process that is considered to represent a cellular response to protect the retina from further damage and to promote its repair following pathological insult. It includes morphological, biochemical and physiological changes, which may vary depending on the type and degree of the initial injury. Not only ...

Age-related macular degeneration (AMD) and diabetic retinopathy (DR), leading causes of blindness, share a common retinal environment: hypoxia which is a major stimulator for the upregulation of vascular endothelial growth factor (VEGF), a cardinal pathogenic factor for the breakdown of blood-retina barrier (BRB). As a result of intensive studies on VEGF pathobiology, anti-VEGF strategy has become a major therapeutics for wet AMD and DR. To investigate the potential impact of anti-VEGF strategy ...

Nephrotoxicity induced by cisplatin in 30% of all cisplatin treated patients seriously limits its clinical implication as a widely used anticancer agent, and may even cause patients to alter or give up cisplatin therapy. The purpose of this study is to test a protective effect of American ginseng berry extract (AGBE) on cisplatin-induced nephrotoxicity in mice. In this study, the histopathological changes and elevated levels of serum creatinine (CRE) and urea nitrogen (BUN) caused by cisplatin w...

Cytosolic phospholipase A2 (cPLA2) is an enzyme that releases arachidonic acid (AA) for the synthesis of eicosanoids and lysophospholipids which play critical roles in the initiation and modulation of oxidative stress and neuroinflammation. In the central nervous system, cPLA2 activation is implicated in the pathogenesis of various neurodegenerative diseases that involves neuroinflammation, thus making it an important pharmacological target. In this paper, a new class of arachidonic acid (AA) an...

Retinal Muller glial cells (RMG) are involved in virtually every retinal disease; however, the role of these glial cells in neuroinflammation is still poorly understood. Since cell surface proteins play a decisive role in immune system signaling pathways, this study aimed at characterizing the changes of the cell surface proteome of RMG after incubation with prototype immune system stimulant lipopolysaccharide (LPS). While mass spectrometric analysis of the human Muller glia cell line MIO-M1 rev...

Aim To investigate whether inhibition of acetylcholinesterase (AChE) by donepezil ameliorate aberrant retinal neovascularization (RNV) and abnormal glial activation in oxygen-induced retinopathy (OIR). Methods A mouse model of RNV was induced in postnatal day 7 (P7) mice by exposure to 75% oxygen. Donepezil was administrated to P12 mice by intraperitoneal injection. Expression and localization of AChE in mouse retinas were determined by immunofluorescence. RNV was evaluated by paraffin sectionin...

Progressive vision loss in adults has become increasingly prevalent worldwide due to retinopathies associated with aging, genetics, and epigenetic factors that damage the retinal microvasculature. Insufficient supply of oxygen and/or nutrients upregulates factors such as vascular endothelial growth factor (VEGF) and epidermal growth factor (EGF), which can induce abnormal angiogenesis and damage the structural arrangement of the retinal blood barrier (BRB). Muller glia (MG) regulate the diffusio...

Neurodegenerative disorders affect millions of adults worldwide. Neuroglia have become recent therapeutic targets due to their reparative abilities in the recycling of exogenous neurotoxins and production of endogenous growth factors for proper functioning of the adult nervous system (NS). Since neuroglia respond effectively to stimuli within in vivo environments on the micron scale, adult glial physiology has remarkable synergy with microscale systems. While clinical studies have begun to explo...
