Research progress of specific pro-resolving mediators in ocular surface diseases

Abstract

Specific pro-resolving mediators(SPM)are a class of lipid mediators that trigger and orchestrate the resolution of inflammation, which formed in cells by the metabolism of polyunsaturated fatty acids. SPM pathway and receptors are highly expressed inocular surface, and constitute endogenous SPM networks which are important for maintaining ocular surface health and immune homeostasis. Recent evidence indicates that SPM and their analogs are essential mediators in promoting corneal wound healing, corneal nerve regeneration, and inhibiting the immune inflammatory response of corneal transplant rejection, allergic conjunctivitis and microbial keratitis. In addition, they are potential therapeutic drug targets of dry eye disease, and provide novel insight on the research and treatment of ocular surface diseases. Here, we will review and discuss evidence for SPM as important endogenous regulators of ocular surface health and disease and their therapeutic potential.
