A calcium-activated, calcium-permeable ion channel in human retinal glial cells: modulation by basic fibroblast growth factor.
نویسنده
چکیده
A calcium-permeable, voltage-insensitive non-specific cation channel that is activated by cytoplasmic calcium was found in approximately 50% of the cell-attached patches in cultured human retinal glial cells sampled by the patch clamp technique. Spontaneous openings of this channel were infrequent, but increased markedly when glial cells were exposed to basic fibroblast growth factor. Although the role of these cation channels is uncertain, they provide a mechanism to perpetuate a transient rise in cytosolic calcium induced by the release of calcium from intracellular stores.

Modulation of calcium channels in human retinal glial cells by basic fibroblast growth factor: a possible role in retinal pathobiology.
The objective of this study was to begin to examine the cellular and biophysical effects on human retinal glial cells of basic fibroblast growth factor (bFGF), which is endogenous to the retina and likely to play a role in retinal pathobiology. Experiments were performed on cultured glial cells derived from the adult postmortem retina. A proliferative response to bFGF established a sensitivity ...
متن کاملStretch-activated channels in human retinal Muller cells.
The cell-attached and excised patch configurations of the patch clamp technique were used to study stretch-activated ion channels in Muller glial cells that were obtained from postmortem adult human retinas and were maintained in culture. A stretch-activated channel permeable to monovalent and divalent cations was found. Ion channels of this type have not been demonstrated previously in glial c...
متن کاملMitogenic and chemotactic effects of platelet-derived growth factor on human retinal glial cells.
Glial cell migration and proliferation appear to play a role in many of the proliferative retinopathies. Knowledge concerning the regulation of the migratory and proliferative responses of glial cells to pathophysiologic conditions in the human retina is limited. Here, we report that platelet-derived growth factor (PDGF) has both mitogenic and chemotactic effects on human retinal glial cells in...
متن کاملPhysiology of rat retinal pericytes: modulation of ion channel activity by serum-derived molecules.
1. Pericytes, which are contractile cells located on the outer wall of microvessels, are thought to be particularly important in the retina where the ratio of these cells to vascular endothelial cells is the highest of any tissue. Retinal pericytes are of interest since they may regulate capillary blood flow and because their selective loss is an early event in diabetic retinopathy, which is a ...
متن کاملPhagocytosis by human retinal glial cells in culture.
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...
