Long-term Nerve Regeneration in Diabetic Keratopathy Mediated by a Novel NGF Delivery System.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Diabetic keratopathy (DK) is a common chronic metabolic disorder that causes ocular surface complications. Among various therapeutic approaches, local delivery of nerve growth factor (NGF) remains the most effective treatment of DK. However, achieving a sustained therapeutic effect with NGF and the frequent drug delivery burden remain challenging during clinical practice. Here, we developed a novel adeno-associated virus (AAV)-based NGF delivery system that achieved 1-year-long-lasting effects by a single injection. We refined the corneal stromal injection technique, resulting in reduced corneal edema and improved AAV distribution homogeneity. AAV serotype AAV.rh10 exhibited high tropism and specificity to corneal nerves. A dose of 2 × 109 vector genomes was determined to achieve efficient Ngf gene expression without inducing corneal immune responses. Moreover, NGF protein was highly expressed in trigeminal ganglion through a retrograde transport mechanism, indicating the capacity for repairing corneal nerve damage at both the root and corneal nerve endings. In a mouse DK model, a single injection of AAV-Ngf into the corneal stroma led to marked corneal nerve regeneration for over 5 months. Together, we provide a novel therapeutic paradigm for long-term effective treatment of DK, and this therapeutic approach is superior to current DK therapies. ARTICLE HIGHLIGHTS:
