Prostaglandin E(2) (PGE(2)) is a potent suppressor of fibroblast activity. We previously reported that bleomycin-induced pulmonary fibrosis was exaggerated in granulocyte-macrophage colony-stimulating factor knockout (GM-CSF(-/-)) mice compared with wild-type (GM-CSF(+/+)) mice and that increased fibrosis was associated with decreased PGE(2) levels in lung homogenates and alveolar macrophage cu...

Severe pancreatitis is frequently associated with acute lung injury (ALI) and the respiratory distress syndrome. The role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in mediating the ALI associated with secretagogue-induced experimental pancreatitis was evaluated with GM-CSF knockout mice (GM-CSF -/-). Pancreatitis was induced by hourly (12x) intraperitoneal injection of a supr...

Metabolism of surfactant protein (SP) A and dipalmitoylphosphatidylcholine (DPPC) was assessed in alveolar macrophages isolated from granulocyte-macrophage colony-stimulated factor (GM-CSF) gene-targeted [GM(-/-)] mice, wild-type mice, and GM(-/-) mice expressing GM-CSF under control of the SP-C promoter element (SP-C-GM). Although binding and uptake of (125)I-SP-A were significantly increased ...

Many proinflammatory cytokines, such as leptin, play key roles in dynamic regulation of energy expenditure and food intake. The present work tested a role for the proinflammatory cytokine GM-CSF. Central but not peripheral administration of GM-CSF to adult rats significantly decreased food intake and body weight for at least 48 hours. Similar results were observed following central administrati...

Goat manure (GM) is an excellent raw material for anaerobic digestion because of its high total nitrogen content and fermentation stability. Several comparative assays were conducted on the anaerobic co-digestion of GM with three crop residues (CRs), namely, wheat straw (WS), corn stalks (CS) and rice straw (RS), under different mixing ratios. All digesters were implemented simultaneously under...

6 Considering the European regulations, a product need to be labelled as containing GM when 7 the adventitious presence of GM material exceed 0.9%. During collection, crops from many 8 fields are combined to fill a silo. Three management strategies to avoid the risk of mixing GM 9 and non-GM crops were identified by a descriptive work based on cases studies in various 10 region of France: defin...

HIV-1 acquisition can be prevented by broadly neutralizing antibodies (BrNAbs) that target the envelope glycoprotein complex (Env). An ideal vaccine should therefore be able to induce BrNAbs that can provide immunity over a prolonged period of time, but the low intrinsic immunogenicity of HIV-1 Env makes the elicitation of such BrNAbs challenging. Co-stimulatory molecules can increase the immun...

A chronic feeding study to evaluate the safety of genetically modified glyphosate-tolerant soybeans (GM soybeans) was conducted using F344 DuCrj rats. The rats were fed diet containing GM soybeans or Non-GM soybeans at the concentration of 30% in basal diet. Non-GM soybeans were a closely related strain to the GM soybeans. These two diets were adjusted to an identical nutrient level. In this st...

Purified preparations of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF), granulocyte CSF (G-CSF), and interleukin 3 (IL-3 or multi-CSF) alone and in combination, have been compared for their stimulatory effects on human granulocyte-macrophage colony forming cells (GM-CFC). In cultures of unseparated normal human bone marrow, the combinations of G-CSF plus IL-3 and G...
