Simvastatin alleviates airway inflammation and remodelling through up-regulation of autophagy in mouse models of asthma.

Abstract

Statins have been widely used in inflammatory diseases including asthma, because of their anti-inflammatory and immunomodulatory properties. It has been shown that simvastatin induces autophagy and cell death in some circumstances. However, the possible cross-talk between simvastatin and autophagic processes in lung disease is largely unknown. Thus, we investigated the impact of simvastatin on airway inflammation and airway remodelling and the possible relationship of these processes to a simvastatin-induced autophagic pathway in mouse models of asthma.
