Figure 5. P2X7 receptor expression and activation on retinal epithelial cells. Cells were fixed, permeabilized, and then incubated with a P2X7 antibody (A). Nuclei were stained with propidium iodide. Cells were observed using the confocal microscopy. P2X7 receptor activation by ATP and BzATP causes YO-PRO-1 dye uptake in retinal cells (B).
