Expression of RANTES by bronchoalveolar lavage cells in nonsmoking patients with interstitial lung diseases.

abstract：:Macrophages are key orchestrators of the inflammatory and repair responses in the lung, and the diversity of their function is indicated by their polarized states and distinct subpopulations and localization in the lung. Here, we characterized the pulmonary macrophage populations in the interstitial and alveolar compa...
