FGFR1, signaling, and AP-1 expression after retinal detachment: reactive Müller and RPE cells.

Abstract

These data suggest that nonneuronal cells (RPE and Müller cells) respond to RD very rapidly by stimulating ERK signaling and AP-1 transcription factor expression. Furthermore, these data suggest that basic fibroblast growth factor (FGF-2, bFGF) is involved in initiating the retina's earliest responses to RD. The events described here precede changes in gene expression and morphology that can have serious effects on visual outcome in humans treated for retinal detachment or other retinal injuries.
