The role of lipid rafts in LPS-induced signaling in a macrophage cell line.
The significance of lipid rafts in lipopolysaccharide (LPS) signaling in macrophages was studied through isolation of them by gradient centrifugation and subsequent visualization of signal moleculesExpand

Regulation of phospholipid biosynthesis in isolated rat hepatocytes. Effect of different substrates.
The effects of choline, ethanolamine and its N-methyl analogs, different fatty acids, and L-methionine on phospholipid biosynthesis via the CDP-ester pathways and the methylation pathway were studiedExpand

Bafilomycin A1 inhibits lysosomal, phagosomal, and plasma membrane H+‐ATPase and induces lysosomal enzyme secretion in macrophages
Bafilomycin A1, a specific inhibitor of H+‐ATPases of the vacuolar type, was in the present study shown, at similar concentrations, to induce secretion of lysosomal enzyme and to elevate lysosomal pHExpand

Dexamethasone down-regulates the 85 kDa phospholipase A2 in mouse macrophages and suppresses its activation.
We have studied the effects of dexamethasone (dex) (i) on the level of the arachidonate-mobilizing phospholipase A2 (PLA2-85) in macrophages, (ii) on the stimulus-induced activation of this enzyme,Expand

Posttranscriptional regulation of TNFalpha expression via eukaryotic initiation factor 4E (eIF4E) phosphorylation in mouse macrophages.
Resident mouse macrophages secrete Tumor necrosis factor alpha (TNFalpha) upon challenge with LPS. The production of TNFalpha is controlled not only at the transcription of the gene, but also byExpand

An 100-kDa arachidonate-mobilizing phospholipase A2 in mouse spleen and the macrophage cell line J774. Purification, substrate interaction and phosphorylation by protein kinase C.
A phospholipase A2 hydrolyzing arachidonic-acid-containing phospholipids has been purified 5600-fold from mouse spleen and to near homogeneity from the macrophage cell line J774. A molecular mass ofExpand

Control of membrane fusion by phospholipid head groups. II. The role of phosphatidylethanolamine in mixtures with phosphatidate and phosphatidylinositol.
Membrane fusion induced by Ca2+ and Mg2+ in large unilamellar vesicles composed of mixtures of phosphatidylethanolamine with phosphatidate and phosphatidylinositol was studied by means of aExpand

Signaling to localized degranulation in neutrophils adherent to immune complexes
The present study demonstrates that the secretion of azurophilic granules occurring during Fc receptor‐mediated attachment and spreading of neutrophils is highly localized to the adhering region ofExpand

Signalling to translational activation of tumour necrosis factor-alpha expression in human THP-1 cells.
Monocytic THP-1 cells expressed tumour necrosis factor-alpha (TNF-alpha) mRNA, but hardly any detectable TNF-alpha protein and a partially activated MAP kinase ERK-2 in the unstimulated state.Expand
