Table 2. Summary of labeling density of caveolin-2 at different regions in human retina

Caveolin-2 was found in the outer nuclear layer (ONL) and the inner limiting membrane (ILM), including the intervening layers, showing very low, low and moderate densities (M). Very low and low density was seen at the periphery (P), but no signals were observed at the most peripheral part (CB). - indicates none; + indicates very low; ++ indicates low; +++ indicates moderate; ++++ indicates high; +++++ indicates very high. Following abbreviations are used: pigment epithelium (PE), outer segments (OS), outer limiting membrane (OLM), outer plexiform layer (OPL), inner nuclear layer (IPL), inner plexiform layer (INL), ganglion cells (GC), optic nerve fibers (ONF).
