Abstract/OtherAbstract:
The C-C motif chemokine ligand 5 (CCL5), CCL11, and CCL24 are involved in the pathogenesis of asthma, and their function is mainly associated with the airway recruitment of eosinophils. This study tested their ability to induce the migration of circulating fibrocytes, which may contribute to the development of irreversible airflow obstruction in severe asthma. The sputum fluid phase (SFP) from patients with severe/treatment-refractory asthma (PwSA) contained elevated concentrations of CCL5, CCL11, and CCL24 in comparison with the SFP from patients with non-severe/treatment-responsive asthma (PwNSA). The circulating fibrocytes from PwSA expressed the receptors for these chemokines at increased levels and migrated in response to recombinant CCL5, CCL11, and CCL24. The SFP from PwSA induced the migration of autologous fibrocytes, and its activity was significantly attenuated by neutralization of endogenous CCL5, CCL11, and CCL24. These findings suggest that CCL5, CCL11, and CCL24 may contribute to the airway recruitment of fibrocytes in severe asthma.Mucosal Immunology advance online publication 14 November 2012; doi:10.1038/mi.2012.109.
