Resolvin E1 as a novel agent for the treatment of asthma

Abstract

Background: Asthma is characterized by airway hyperresponsiveness and chronic airway inflammation. Inflammatory cells, including eosinophils and lymphocytes, infiltrate peribronchial tissue in patients with asthma. Resolvin E1 (RvE1) is an anti-inflammatory lipid mediator derived from the omega-3 fatty acid, eicosapentaenoic acid, and has been shown to be involved in resolving inflammation. Although little is known about the actions of RvE1 in the resolution of inflammation due to asthma, recent studies in a mouse model have shown the possibilities of RvE1 in asthma. Objective/methods: We review the current understanding of the mechanism of RvE1 action in connection with asthma pathogenesis and treatment. Results/conclusion: Findings provide evidence for the use of RvE1 as a pivotal counter-regulatory signal in allergic inflammation and offer the possibility of novel multi-pronged therapeutic approaches for human asthma.
