Hypoxic regulation of the inflammatory lung neutrophil proteome


ABSTRACT: This project aimed to define the proteome of inflammatory lung neutrophils and determine how his is regulated by exposure to in vivo hypoxia. An acute lung injury was induced using nebulised LPS. Following LPS administration mice were housed in either normal room air or in a hypoxic chamber set at an inspired oxygen concentration of 10%. Highly pure bronchoalveolar lavage (BAL) neutrophils were isolated from the lungs of C57Bl6 mice 24 hours after being treated with LPS.

Limiting dysfunctional neutrophilic inflammation while preserving effective immunity requires a better understanding of the processes that dictate neutrophil function in the tissues. Quantitative mass-spectrometry identified how inflammatory murine neutrophils regulated expression of cell surface receptors, signal transduction networks, and metabolic machinery to shape neutrophil phenotypes in response to hypoxia. Through the tracing of labeled amino acids into metabolic enzymes, proinflammatory  ...[more]
