Allergen Challenge Increases Cell Traffic between Bone Marrow and Lung

Increases in inflammatory-cell progenitors have been demonstrated in the bone marrow (BM) after inhalation of Ascaris suum in dogs at the time of allergen-induced airway hyperresponsiveness (AHR). The aim of this study was to evaluate the effect of allergen challenge on trafficking of inflammatory cells and their progenitors from the BM to the lung, using a marker of proliferating cells, bromodeoxyuridine (BrdU). BrdU is a thymidine analogue …
