This study aims to investigate which recognition pathways are important in engulfing apoptotic eosinophils.Here, two epithelial cell were selected namely (large airway bronchial epithelial cells) LAECs and A549. The inhibition assay was examined by resting and dexamethasone-stimulated epithelial cells. Confocal microscopy confirmed the engulfment of apoptotic eosinophils.Macrophages and LAECs recognized and phagocytosed apoptotic eosinophils. Dexamethasone and IL-1 increased the capacity of LAECs to engulf apoptotic eosinophils. More interestingly, inhibiting monoclonal antibodies (Mabs) abolished the uptake of apoptotic cells by LAECs.On the basis of the above findings, the LAECs is capable of recognizing and engulfing apoptotic eosinophils and that enhanced by interleukin-1 (IL-1â) and dexamethasone.
