The signaling pathways downstream of CD18 integrins are dependent on the spleen tyrosine kinase, Syk. To investigate the role integrin signaling plays in host defense, we examined the responses of Syk-deficient neutrophils to bacterial challenge with serum-opsonized Staphylococcus aureus and Escherichia coli. Syk-conditional knockout mice lacking this kinase specifically in myeloid cells or just neutrophils were also used to investigate host responses in vivo. Syk-deficient neutrophils manifested impaired exocytosis of secondary and tertiary granules, reduced cytokine release, and very poor activation of the NADPH oxidase in response to serum-opsonized S aureus and E coli. These functional defects correlated with impaired activation of c-Cbl, Pyk2, Erk1/2, and p38 kinases. Bacterial phagocytosis, neutrophil extracellular trap formation, and killing were also reduced in Syk-deficient cells, with a more profound effect after S aureus challenge. In vivo, loss of Syk in myeloid cells or specifically in neutrophils resulted in reduced clearance of S aureus after subcutaneous or intraperitoneal infection, despite normal recruitment of inflammatory cells. These results indicate that loss of Syk kinase-mediated integrin signaling impairs leukocyte activation, leading to reduced host defense responses."xsd:string |
