Emerging Peptide Therapies for Dry Eye

The landscape of peptide-based treatments for dry eye is rapidly evolving, with several distinct categories of peptides showing promise. These include mimetic peptides designed to replicate the function of naturally occurring molecules, regenerative peptides that encourage tissue repair, and antimicrobial peptides that combat infection and inflammation.

Mimetic Peptides: These are synthetic or derived peptides that mimic the biological activity of endogenous molecules. For instance, a PEDF (pigment epithelium-derived factor) peptide mimetic has shown efficacy in relieving dry eye by restoring corneal sensitivity. Another example is ST-100, a novel collagen mimetic peptide developed to repair damaged collagen in the eye and restore homeostatic cell signaling in the ocular epitheliumAG-80308 for dry eye disease on track for Phase 2 clinical .... These agents aim to directly address specific pathways involved in dry eye pathogenesis.

Regenerative Peptides: These peptides focus on promoting the eye's natural healing processes.2024年7月28日—AG-8030 is a first-in-class, formyl peptide receptor (FPR) agonistformulated as an aqueous solution eye drop for the treatment of DED. Advances in regenerative peptide therapy are paving the way for more reliable and affordable treatment options, particularly for severe dry eye disease. BRM421, a synthetic peptide inspired by PEDF, is one such example, offering both neurotrophic and anti-inflammatory effects to support corneal healing.

Antimicrobial Peptides (AMPs): The ocular surface hosts a complex microbiome, and imbalances can contribute to dry eye.
