High-dimensional analysis of the murine myeloid cell system.
Singapore, Singapore. In Nat Immunol, 31 Dec 2014
Using mice that cannot sense granulocyte macrophage-colony stimulating factor GM-CSF (Csf2rb(-/-)), which have discrete alterations in myeloid development, we confirmed differences in barrier tissue dendritic cells, lung macrophages and eosinophils.
Oxyresveratrol suppresses lipopolysaccharide-induced inflammatory responses in murine macrophages.
Pusan, South Korea. In Hum Exp Toxicol, 25 Dec 2014
Production of nitric oxide (NO), prostaglandin E2 (PGE2), messenger RNA (mRNA) and protein expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin 6 (IL-6), and granulocyte macrophage colony-stimulating factor (GM-CSF), phosphorylation of mitogen-activated protein kinases (MAPKs; extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), p38), and the activation of nuclear factor κ-light chain enhancer of activated B cells (NFκB) with OxyR were assayed in LPS-stimulated RAW264.7 cells.
Pulmonary macrophage transplantation therapy.
Cincinnati, United States. In Nature, 23 Nov 2014
Here, using granulocyte-macrophage colony-stimulating factor (GM-CSF) receptor-β-deficient (Csf2rb(-/-)) mice that develop a myeloid cell disorder identical to hereditary pulmonary alveolar proteinosis (hPAP) in children with CSF2RA or CSF2RB mutations, we show that pulmonary macrophage transplantation (PMT) of either wild-type or Csf2rb-gene-corrected macrophages without myeloablation was safe and well-tolerated and that one administration corrected the lung disease, secondary systemic manifestations and normalized disease-related biomarkers, and prevented disease-specific mortality.
Secondary pulmonary alveolar proteinosis in hematologic malignancies.
Weston, United States. In Hematol Oncol Stem Cell Ther, 06 Nov 2014
Idiopathic PAP occurs as a result of auto-antibodies directed against granulocyte-macrophage colony stimulating factor (GM-CSF) impeding the surfactant clearing function of alveolar macrophages leading to progressive respiratory failure.
