Abstract

BACKGROUND: The membrane-bound isoform of the receptor for advanced glycation end products (FL-RAGE) is primarily expressed by alveolar epithelial cells and undergoes shedding by the protease ADAM10, giving rise to soluble cleaved RAGE (cRAGE). RAGE has been associated with the pathogenesis of several acute and chronic lung disorders. Whether the proteolysis of FL-RAGE is altered by a given inflammatory stimulus is unknown. Pseudomonas aeruginosa causes nosocomial infections in hospitalized patients and is the major pathogen associated with chronic lung diseases. METHODS: P. aeruginosa was injected in Rage-/- and wild-type mice and the impact on RAGE expression and shedding, levels of inflammation and bacterial growth was determined. RESULTS: Acute P. aeruginosa lung infection in mice induces a reduction of the active form of ADAM10, which determines an increase of FL-RAGE expression on alveolar cells and a concomitant decrease of pulmonary cRAGE levels. This was associated with massive recruitment of leukocytes and release of pro-inflammatory factors, tissue damage and relocation of cRAGE in the alveolar and bronchial cavities. The administration of sRAGE worsened bacterial burden and neutrophils infiltration. RAGE genetic deficiency reduced the susceptibility to P. aeruginosa infection, mitigating leukocyte recruitment, inflammatory molecules production, and bacterial growth. CONCLUSIONS: These data are the first to suggest that inhibition of FL-RAGE shedding, by affecting the FL-RAGE/cRAGE levels, is a novel mechanism for controlling inflammation to acute P. aeruginosa pneumonia. sRAGE in the alveolar space sustains inflammation in this setting. GENERAL SIGNIFICANCE: RAGE shedding may determine the progression of inflammatory lung diseases. Copyright © 2016 Elsevier B.V. All rights reserved.
