IntroductionSince the pioneering works of David Sabatini’s group,viruses have demonstrated their high usefulness to unravelproperties of eukaryotic cells. This holds especially true forstudies on polarized protein targeting in epithelial cells inwh

TCR signal initiation machinery is pre-assembled and activated in a subset of membrane rafts

Publikováno v: The EMBO Journal. 21:1899-1908

Recent studies suggest that rafts are involved in numerous cell functions, including membrane traffic and signaling. Here we demonstrate, using a polyoxyethylene ether Brij 98, that detergent-insoluble microdomains possessing the expected biochemical

Resistance to TNF-Induced Cytotoxicity Correlates with an Abnormal Cleavage of Cytosolic Phospholipase A2

Autor: Joëlle Masliah, Nour-Eddine El Mahdani, Salem Chouaib, Odile Colard, Zhenzi Cai, Maya Ameyar

Publikováno v: The Journal of Immunology. 165:6756-6761

To investigate the mechanism underlying the absence of arachidonic acid (AA) release by TNF in TNF-resistant cells, we first performed comparative analysis of phospholipid pools in both TNF-sensitive (MCF7) and their equivalent resistant cells (C1001

Transacylase-mediated alkylacyl-GPC synthesis and its hydrolysis by phospholipase D occur in separate cell compartments in the human neutrophil

Publikováno v: Journal of Cellular Biochemistry. 62:56-68

Subcellular localizations of CoA-independent transacylase and phospholipase D enzymes have been investigated in human neutrophils performing a two-step gradient system to separate plasma membranes from internal membranes and from the bulk of granules

Biosynthesis of platelet-activating factor in cultured mast cells.. Involvement of the CoA-independent transacylase demonstrated by analysis of the molecular species of platelet-activating factor

Autor: Odile Colard, Ewa Ninio, Jocelyne Bidault, Michelyne Breton

Publikováno v: European Journal of Biochemistry. 216:835-840

We have recently demonstrated that arachidonate [20:4(5,8,11,14)] was primarily linked to the hexadecyl (16:0) and octadecenyl (18:1) species of alkylacyl derivatives of glycerolphosphocholine (GroPCho). Consistent with the involvement of arachidonat

Heterogeneity of arachidonate and paf-acether precursor pools in mast cells

Autor: Odile Colard, Ewa Ninio, Claude Wolf, Francine Joly, Michelyne Breton

Publikováno v: Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism. 1125:305-312

In mammalian cells, arachidonate release and paf-acether formation are frequently associated. The alkyl-acyl-GPC has been proposed as an important source for released arachidonic acid and arachidonate-containing alkylacyl-GPC species as unique precur

A unique pool of free arachidonate serves as substrate for both cyclooxygenase and lipoxygenase in platelets

Autor: Odile Colard, Françoise Chevy, Claude Wolf

Publikováno v: Lipids. 26:1080-1085

Stimulation of platelets induces a rapid release of arachidonate from specific phospholipids and subsequent remodeling of arachidonate-containing phospholipids. This process is accompanied by transformation of released arachidonate by cyclooxygenase

Protein kinase C promotes arachidonate mobilization through enhancement of CoA-independent transacylase activity in platelets

Autor: Odile Colard, Michelyne Breton

Publikováno v: Biochemical Journal. 280:93-98

A role for protein kinase C in arachidonate mobilization was demonstrated. Treatment of rat platelets with phorbol myristate acetate (PMA) or the diacylglycerol 1-oleoyl-2-acetylglycerol increased the transfer rate of arachidonate (AA) from phosphati

Very high proportion of disaturated molecular species in rat platelet diacyl-glycerophosphocholine: Involvement of CoA-dependent transacylation reactions

Autor: Gilbert Bereziat, Odile Colard, Hassane Masrar

Publikováno v: Archives of Biochemistry and Biophysics. 281:116-123

The molecular species composition of rat platelet diacyl-glycerophosphocholine (GPC) was investigated by reverse-phase HPLC and by mass spectrometry. The two methods gave the same very high proportion of fully saturated phospholipids, the 16:0–16:0
