Effect of Polarization on Airway Epithelial Conditioning of Monocyte-Derived Dendritic Cells.

Airway epithelial cells (AECs) form polarized barriers that interact with inhaled allergens and are involved in immune homeostasis. We examined how monocyte-derived dendritic cells (MDDCs) are affected by contact with the airway epithelium. In traditional setups, bronchial epithelial cell lines were allowed to polarize on filter inserts, and MDDCs were allowed to adhere to the epithelial basal side.
