Vasoactive intestinal peptide is an agonist of VPAC1/VPAC2 receptor (G-protein-coupled receptors). Vasoactive intestinal peptide reduces corneal perforation rate, bacterial load, and excessive neutrophil infiltration in Pseudomonas aeruginosa-induced keratitis models. Vasoactive intestinal peptide enhances anti-inflammatory mediators like IL-10 and TGF-β, inhibites pro-inflammatory factors such as IL-1β and TNF-α, and upregulates lipid mediator-related enzymes (SOCS3, COX-2, ALOX12) to promote inflammation resolution. Vasoactive intestinal peptide is promising for research of ocular infectious diseases.
