A novel organotypic culture method of mouse retina explants is being introduced and characterized to evaluate its usefulness in studying glutamate excitotoxicity. Retinal whole-mounts were dissected from eyes of C57BL/6 mice aged P10-14 and transferred to poly-D-lysine/laminin coated round coverslips. After 7 days in vitro, retina explants were treated with(More)
PURPOSE Lacrimal glands regulate the production and secretion of tear fluid. Dysfunction of lacrimal gland acinar cells can ultimately result in ocular surface disorders, such as dry eye disease. Ca(2+) homeostasis is tightly regulated in the cellular environment, and secretion from the acinar cells of the lacrimal gland is regulated by both cholinergic and(More)
Inositol 1,4,5-trisphosphate receptors (IP(3)R) are ligand-gated intracellular Ca(2+)channels that mediate release of Ca(2+) from intracellular stores into the cytosol on activation by second messenger IP(3.). Similarly, IP(3)R mediated changes in cytosolic Ca(2+) concentrations control neuronal functions ranging from synaptic transmission to(More)
