Abstract
Airway inflammation is a defense mechanism against inhaled agents characterized by infiltration of circulating immune cells. Given the inconsistent cellular identification across pre-clinical rat model, we have developed a flow cytometry panel of six colors to characterize macrophages subsets, lymphocytes and granulocytes in bronchoalveolar lavage fluid (BAL). Rats were challenged with intratracheal instillation of lipopolysaccharide (LPS). BAL were harvested 24 h after one LPS exposure in rats. This flow cytometry panel involve the description of macrophage subsets, T and B lymphocytes and neutrophils, which are central to airway immune responses, as based on scientific literature. By using a relatively small number of parameters to identify multiple cell types, additional parameters can be used for project/disease-specific activation markers.
