Integrin-mediated adhesion of monocytes and macrophages initiates a signal transduction pathway that leads to actin cytoskeletal reorganization, cell migration and immunologic activation. This… (More)
Phagocytosis is increased by Fcgamma receptors (FcgammaRs), and studies with syk(-/-) macrophages demonstrated that Syk kinase is required for FcgammaR phagocytosis. Similar studies with macrophages… (More)
Src-family kinases (SFKs) regulate different granulocyte and monocyte/macrophage responses. Accumulating evidence suggests that members of this family are implicated in signal transduction pathways… (More)
Using a mouse model of allergic lung inflammation, we found that mice deficient of Fgr, a Src family tyrosine kinase highly expressed in myelomonocytic cells, fail to develop lung eosinophilia in… (More)
Fgr participates in integrin signaling in myeloid leukocytes. To examine the role of its specific domains in regulating cell migration, we expressed various Fgr molecules in COS-7 cells. Full-length,… (More)
The purposes of this study were to define in sheep a compartmental model for glucose kinetics in the basal condition and to test the hypothesis that interstitial fluid obtained by sampling thoracic… (More)
Myeloid leukocyte recruitment into the lung in response to environmental cues represents a key factor for the induction of lung damage. We report that Hck- and Fgr-deficient mice show a profound… (More)
Primary macrophages isolated from hck(-/-)fgr(-/-) mice display altered morphology and F-actin cytoskeletal structures and reduced migration. The ability of phorbol myristyl acetate (PMA), a protein… (More)
A model of bicarbonate kinetics is crucial to a correct interpretation of experiments for measuring oxidation in vivo of carbon-labeled compounds. The aim of this study is to develop a compartmental… (More)
