Ciliary neurotrophic factor induces genes associated with inflammatory response and gliosis in the retina: A gene profiling study of flow-sorted, Muller (glial) cells

ABSTRACT: Our data suggest that CNTF remodels the transcription profile of Muller (glial) cells leading to induction of networks associated with transcription, cell cycle regulation and inflammatory response. CNTF also appears to function as an inducer of gliosis in the retina. These studies provide new insights into the biological functions of cytokines in the retina. Muller glial cells treated with CNTF for 1 and 3 days

<h4>Background</h4>Ciliary neurotrophic factor (CNTF), a member of the interleukin-6 cytokine family, has been implicated in the development, differentiation and survival of retinal neurons. The mechanisms of CNTF action as well as its cellular targets in the retina are poorly understood. It has been postulated that some of the biological effects of CNTF are mediated through its action via retinal glial cells; however, molecular changes in retinal glia induced by CNTF have not been elucidated.

Gene expression changes under cyclic mechanical stretch in rat retinal Muller cells

Project description:The retina is often subjected to tractional forces in a variety of conditions, for instance, pathological myopia, proliferative vitreoretinopathy. As the predominant glial element in the sensory retina, Muller cells are responsible for the homeostatic and metabolic support of retinal neurons and active players in virtually all forms of retinal injury and disease. Besides, Muller cells span the entire retinal thickness, extending from the inner to the outer limiting membranes, with cell bodies located in the inner nuclear layer and lateral processes expanding into the plexiform layers of the tissue. Because of this unique morphology, Muller cells can sense even minute changes in the retinal structure because of the mechanical stretching of their long processes or side branches. Thus, itM-bM-^@M-^Ys reasonable to infer that Muller cells also participate in ocular diseases when the retina is overstretched. In this study, we aim to investigate the whole genome regulation of Muller cells under mechanical stretching, which may help in excluding possible molecular mechanisms that would account for many retinal diseases in which the retina is often subjected to mechanical forces. We used microarrays to identify patterns of gene expression changes induced by cyclic mechanical stretching in Muller cells. Rat Muller cells were seeded onto flexible bottom culture plates and subjected to a cyclic stretching regimen of 15% equibiaxial stretching for 1 and 24 h.Muller cells cultured under the same conditions but with no applied mechanical strain were considered as the unstretched control. At each time points (1 and 24 h), three totally independent experiments (3 stretched samples and 3 control samples) were conducted. Muller cells were selected for RNA extraction and hybridization on Affymetrix microarrays. Stretch (S); Control (C)

Protective gene expression changes elicited by an inherited defect in photoreceptor structure.

Project description:To investigate pathogenic mechanisms in such instances, we have characterized rod photoreceptor and retinal gene expression changes in response to a defined insult to photoreceptor structure, using the retinal degeneration slow (rds) mouse model. Global gene expression profiling was performed on flow-sorted rds and wild-type rod photoreceptors immediately prior and subsequent to times at which OSs are normally elaborated. Dysregulated genes were identified via microarray hybridization, and selected candidates were validated using quantitative PCR analyses. We identified a single key gene, Egr1, that was dysregulated in a sustained fashion in rds rod photoreceptors and in the retina. Egr1 upregulation was associated with microglial activation and migration, into the outer retina at times subsequent to the major peak of photoreceptor cell death. Interestingly, this response was accompanied by neurotrophic factor upregulation. We hypothesize that activation of Egr1 and neurotrophic factors represents a protective immune mechanism, contributing to the characteristically slow retinal degeneration of the rds mouse model. We had two conditions WT and Rds-KO at 4 different time points: postnatal (P) 6, P9, P14 and P21.
