We have generated Fas activated serine threonine phosphoprotein-deficient mice (FAST−/−) to study the in vivo role of FAST in immune system function. In a model of house dust mite (HDM)-induced allergic pulmonary inflammation, wild type mice develop a mixed cellular infiltrate composed of eosinophils, lymphocytes and neutrophils. FAST−/− mice develop airway inflammation that is distinguished by the near absence of neutrophils. Similarly, LPS-induced alveolar neutrophil recruitment is markedly reduced in FAST−/− mice compared to wild type controls. This is accompanied by reduced concentrations of cytokines (TNF-α, IL-6 and IL-23) and chemoattractants (MIP-2 and KC) in bronchoalveolar lavage fluids. As FAST−/− neutrophils exhibit normal chemotaxis and survival, impaired neutrophil recruitment is likely to be due to reduced production of chemoattractants within the pulmonary parenchyma. Studies using bone marrow chimeras implicate lung resident hematopoietic cells (e.g. pulmonary dendritic cells and/or alveolar macrophages) in this process. In conclusion, our results introduce FAST as a pro-inflammatory factor that modulates the function of lung resident hematopoietic cells to promote neutrophil recruitment and pulmonary inflammation.
