Release of Different Cell Mediators During Retinal Pigment Epithelium Regeneration Following Selective Retina Therapy.
Purpose To investigate the effect of selective retina therapy (SRT) on the release of AMD-relevant cell mediators, such as matrix metalloproteinases (MMPs), VEGF, and pigment epithelium derived factor (PEDF) using different laser spot sizes and densities. Methods Porcine RPE-choroid explants were treated with a pulsed 532 nm Nd:YAG laser using (1) large spot sizes, (2) small spot sizes with a...
متن کاملLaser-mediated activation of human retinal pigment epithelial cells and concomitant release of matrix metalloproteinases.
PURPOSE To investigate cellular dynamics and associated matrix metalloproteinase (MMP) release patterns of human retinal pigment epithelium (RPE) cells subsequent to irradiation by nanosecond pulsed laser at energy levels below visual threshold. METHODS Following a stabilization period, human RPE-Bruch's-choroid explants were irradiated with a nanosecond laser system (Q-switched, frequency do...
متن کاملPolarity of 11-cis retinal release from cultured retinal pigment epithelium.
PURPOSE Fetal bovine retinal pigment epithelium (RPE) was grown on porous supports to investigate the polarity of 11-cis retinal (RAL) release from these cells and the influence that the interphotoreceptor retinoid-binding protein (IRBP) has on this process. METHODS [3H]all-trans retinol (ROL) was delivered to the basal surface of the cultured RPE by serum retinol-binding protein (RBP). Apo I...
متن کاملRelease of ATP from retinal pigment epithelial cells involves both CFTR and vesicular transport.
The retinal pigment epithelium (RPE) faces the photoreceptor outer segments and regulates the composition of the interstitial subretinal space. ATP enhances fluid movement from the subretinal space across the RPE. RPE cells can themselves release ATP, but the mechanisms and polarity of this release are unknown. The RPE expresses the cystic fibrosis transmembrane conductance regulator (CFTR), an...
متن کاملDirect Electrochemical Capture and Release of Carbon Dioxide Using an Industrial Organic Pigment: Quinacridone**
Limiting anthropogenic carbon dioxide emissions constitutes a major issue faced by scientists today. Herein we report an efficient way of controlled capture and release of carbon dioxide using nature inspired, cheap, abundant and non-toxic, industrial pigment namely, quinacridone. An electrochemically reduced electrode consisting of a quinacridone thin film (ca. 100 nm thick) on an ITO support ...
