Under a variety of pathologic conditions, glial cells of the retina are capable of phagocytosis. Although phagocytosis may play a role in retinal pathobiology, the regulation of the phagocytic activity of retinal glial cells is poorly understood. We used a culture system to study phagocytosis by human retinal glial cells. The cultured cells were obtained from adult postmortem eyes and were immu...
Objective(s)Progesterone is a steroid hormone whose biology has been greatly studied within the confines of reproductive function. In recent years, the neuroprotective effects of progesterone have attracted growing interest. Glial cell line-derived neurotrophic factor (GDNF), is a neurotrophic factor which plays a crucial role in the development and maintenance of distinct sets of central and p...
PURPOSE To modify existing experimental models to simulate the typical clinical presentation of human rhegmatogenous retinal detachment (RRD), namely an RD caused by a retinal break, in a phakic eye, with a posterior vitreous detachment (PVD); to model RRD in a species that is anatomically similar to humans; and to characterize the glial cell response to RRD. METHODS Mixed-breed pigs underwen...
Bergmann glial cells are specialized astrocytes in the cerebellum. In the mature cerebellar molecular layer, Bergmann glial processes are closely associated with Purkinje cells, enclosing Purkinje cell dendritic synapses with a glial sheath. There is intensive gap junctional coupling between Bergmann glial processes, but their significance in cerebellar functions is not known. Connexin43 (Cx43)...
By means of a multistage quantitative assay, we have identified a new kind of cell adhesion molecule (CAM) on neuronal cells of the chick embryo that is involved in their adhesion to glial cells. The assay used to identify the binding component (which we name neuron-glia CAM or Ng-CAM) was designed to distinguish between homotypic binding (e.g., neuron to neuron) and heterotypic binding (e.g., ...
Background: Alzheimer’s disease (AD) is characterized by progressive neuronal loss in hippocamp. Epidermal neural crest stem cells (EPI-NCSC) can differentiate into neurons, astrocytes and oligodendrocytes. The purpose of this study was to evaluate the effects of transplanting EPI-NCSC into AD rat model. Methods: Two weeks after induction of AD by injection of Amyloid-β 1-40 into CA1 area of ra...
We have localized the guanine nucleotide-binding protein, Go, in primary cultures of pure neuronal and glial cells prepared from different mouse brain areas. Immunoblotting experiments with selective affinity-purified polyclonal rabbit antibodies to the 39 kDa alpha subunit of Go (Go alpha) indicated that Go is distributed in both neurons and glial cells. Go alpha accounts for 0.3% of total mem...
Introduction: Alzheimer disease (AD), known to be a leading cause of dementia that causes heavy social and financial burdens worldwide, characterized by progressive loss of neurons and synaptic connectivity after depositions of amyloid-β (Aβ) protein.AD manifests as an impaired ability to comprehend or use words, poor coordination and gait, and impaired executive functions in the realms of plan...
Objective(s): The Muller cell is the principal glial cell of the vertebrate retina. The expression of Glial fibrillary acidic protein (GFAP) in the Muller cells was used as a cellular marker for retinal damage. This study was done to evaluate the effect of gestational diabetes on retinal Muller cells in rat's offspring. Materials and Methods: In this experimental study, 12 Wistar rat dams were ...
Three classes of glial cells are present early in embryogenesis and appear to play a major role in axon pathway formation in the Drosophila CNS. Six longitudinal glial (LG) cells are present over the longitudinal connective on each side of each segment. Six midline glia (MG) cells surround the anterior and posterior commissures of each segment. Finally, the intersegmental nerve root is covered ...
