Formyl peptide receptors as therapeutic targets in eye disease.

Once known only as immune sentinels, formyl peptide receptors (FPRs) have emerged as paradoxical regulators of ocular health, capable of driving injury or repair in a ligand-dependent manner. We discuss FPR signaling in diabetic retinopathy, dry eye disease, and retinitis pigmentosa, highlighting therapeutic opportunities arising from biased receptor modulation.
