诱导小鼠角膜神经营养性角膜炎和神经再生的三种策略

Executive Industry Relevance

Robust preclinical models of neurotrophic keratitis are essential for de-risking early-stage ophthalmic drug discovery and regenerative medicine portfolios. The three murine corneal injury strategies described enable precise interrogation of nerve degeneration and regeneration, supporting predictive confidence in translational research. These models facilitate the evaluation of novel pharmacological and gene therapy candidates targeting corneal nerve repair and disease modification.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables mechanistic dissection of corneal nerve injury and regeneration pathways.
• Supports functional validation of neurotrophic targets in a clinically relevant tissue context.
• Facilitates biological de-risking for candidate therapies aimed at nerve repair.
• Provides a platform for hypothesis-driven interrogation of regenerative mechanisms.

Screening & Assay Development

• Establishes reproducible injury models for quantitative assessment of nerve regeneration.
• Enables standardized evaluation of compound efficacy in restoring corneal innervation.
• Supports development of imaging-based readouts for high-content screening workflows.
• Prepares validated systems for downstream pharmacological and gene therapy testing.

Translational & Preclinical Research

• Aligns preclinical models with clinical presentations of neurotrophic keratitis.
• Enables assessment of disease-relevant endpoints such as epithelial integrity and nerve regrowth.
• Supports risk-adjusted advancement of regenerative candidates toward IND-enabling studies.
• Provides continuity from mechanistic discovery to translational biomarker development.
