Potential Role of Astragaloside IV in the Treatment of Fungal Keratitis

Fungal keratitis (FK) is a worldwide visual impairment disease. The pathogenesis of fungal keratitis involves fungi, corneal cells, inflammatory cell infiltration, collagen degradation, inflammatory cytokines and their interactions. Accumulated evidence indicated that Astragaloside IV (AS-IV) possesses a broad range of pharmacological properties, such as efficacy in anti-inflammation, alleviating fibrosis, and immunomodulatory effects. This paper summarizes new findings regarding AS-IV in immune and inflammatory diseases and analyzes the perspective application of Astragaloside IV in fungal keratitis.
