We investigated the role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in a subchronic exposure model of cigarette smoke (CS)-induced inflammation using antibodies directed against GM-CSF or the GM-CSF receptor (GM-CSFR) α-chain. CS-induced mononuclear and neutrophilic inflammation following 4 days of CS exposure in BALB/c mice was assessed in bronchoalveolar lavage (BAL) fluid. An increase in mature dendritic cells (DCs) (CD11c+ and major histocompatibility complex II+) and Gr-1-high neutrophils was also observed by flow cytometric analysis of whole-lung tissue. Daily i.p. injection of 400 μg GM-CSF or GM-CSFR antibody prior to daily smoke exposure attenuated the accumulation of neutrophils within the BAL by 60%. A reduction in mature DCs was also observed. Anti-GM-CSFR antibody administration did not have an effect on the percentage of lung T-cells; however, a significant decrease in activated CD69+ CD8+ T-cells was observed. Anti-GM-CSFR antibody administration decreased the mRNA and protein expression of interleukin-12 p40 and matrix metalloproteinase 12. Taken together, intervention with this receptor antibody implicates the GM-CSF pathway as an important mediator of smoke-induced inflammation.
