Zymosan 171-178 phospholipase A2 group IB Homo sapiens 68-84 11741884-6 2002 By use of a recently described and specific inhibitor of cytosolic PLA(2)-alpha (group IV PLA(2)alpha), we show that this enzyme produces virtually all of the arachidonic acid used for the biosynthesis of leukotriene B(4) in fMLP- and opsonized zymosan-stimulated neutrophils, the major eicosanoid produced by these pro-inflammatory cells. Zymosan 245-252 phospholipase A2 group IB Homo sapiens 67-73 11741884-6 2002 By use of a recently described and specific inhibitor of cytosolic PLA(2)-alpha (group IV PLA(2)alpha), we show that this enzyme produces virtually all of the arachidonic acid used for the biosynthesis of leukotriene B(4) in fMLP- and opsonized zymosan-stimulated neutrophils, the major eicosanoid produced by these pro-inflammatory cells. Zymosan 245-252 phospholipase A2 group IB Homo sapiens 90-101 8938669-2 1996 Ircinin inhibited Naja naja venom, human synovial recombinant, bee venom and zymosan-injected rat air pouch PLA2 with IC50 values in the microM range, similar to those of the known inhibitor scalaradial. Zymosan 77-84 phospholipase A2 group IB Homo sapiens 108-112 8034717-7 1994 This approach was complicated since initial exposure to PMA to down-regulate PKC increased cytosolic PLA2 activity which remained elevated for 16 h. In contrast, GF109203X treatment suppressed the increase in cytosolic PLA2 activity in response to zymosan and PMA but not to okadaic acid or A23187. Zymosan 248-255 phospholipase A2 group IB Homo sapiens 219-223 8034717-8 1994 The results demonstrate that PMA and zymosan trigger PKC activation that leads to the activation of MAP kinase and PLA2, whereas these responses are PKC independent in okadaic acid-treated cells. Zymosan 37-44 phospholipase A2 group IB Homo sapiens 115-119 8034717-9 1994 In addition, the results are consistent with a role for MAP kinase activation in regulating the activation of the 85-kDa PLA2 and arachidonic acid release in PMA-, zymosan-, and okadaic acid-stimulated cells, whereas these responses in A23187-treated cells are MAP kinase-and PKC-independent. Zymosan 164-171 phospholipase A2 group IB Homo sapiens 121-125 8280102-1 1994 Phospholipase A2 (PLA2) inhibitors suppressed simultaneously, in a dose-dependent manner, the activation of NADPH oxidase and the release of 3H-labelled arachidonic acid ([3H]AA) stimulated by either phorbol 12-myristate 13-acetate (PMA) or opsonized zymosan (OZ) in human neutrophils. Zymosan 251-258 phospholipase A2 group IB Homo sapiens 0-16 8280102-1 1994 Phospholipase A2 (PLA2) inhibitors suppressed simultaneously, in a dose-dependent manner, the activation of NADPH oxidase and the release of 3H-labelled arachidonic acid ([3H]AA) stimulated by either phorbol 12-myristate 13-acetate (PMA) or opsonized zymosan (OZ) in human neutrophils. Zymosan 251-258 phospholipase A2 group IB Homo sapiens 18-22 8108369-3 1994 However, both types of PLA2 promoted opsonized zymosan-induced LTB4 production in a dose-dependent manner (from 10(-10) to 10(-8) M), whereas they had no effect on opsonized zymosan-induced LTC4 generation. Zymosan 47-54 phospholipase A2 group IB Homo sapiens 23-27 1505682-1 1992 Vanadate (V) potentiated (4- to 10-fold) the activation of cellular phospholipase A2 (PLA2) induced by H2O2 (H), a phorbol ester (T), a Ca(2+)-ionophore (A) and opsonized zymosan in macrophages. Zymosan 171-178 phospholipase A2 group IB Homo sapiens 86-90 2775481-3 1989 Also the zymosan-induced formation of thromboxane and prostaglandin E2 from endogenous sources which is thought to involve phospholipase A2 remains unaffected in the presence of this compound. Zymosan 9-16 phospholipase A2 group IB Homo sapiens 123-139 3065613-2 1988 In the perfused liver, responses (e.g. vasoconstriction and glycogenolysis) to stimulating agents such as zymosan, platelet-activating factor and arachidonic acid, are inhibited by indomethacin and bromophenacyl bromide, inhibitors of cyclo-oxygenase and phospholipase A2, respectively. Zymosan 106-113 phospholipase A2 group IB Homo sapiens 255-271 6818414-4 1982 These observations suggest that the zymosan-activated serum stimulus activates phospholipase A2 and that phospholipase A2 is inhibited by quercetin. Zymosan 36-43 phospholipase A2 group IB Homo sapiens 79-95 6818414-4 1982 These observations suggest that the zymosan-activated serum stimulus activates phospholipase A2 and that phospholipase A2 is inhibited by quercetin. Zymosan 36-43 phospholipase A2 group IB Homo sapiens 105-121 6783644-6 1981 Increased activities of phospholipase A2 were achieved by treatment with the bivalent cation ionophore A 23187 and with zymosan. Zymosan 120-127 phospholipase A2 group IB Homo sapiens 24-40 6783644-7 1981 The effect of zymosan obtained from various sources was found to be exclusively due to contamination of tee zymosan particles with phospholipase A2 activity. Zymosan 14-21 phospholipase A2 group IB Homo sapiens 131-147 6783644-7 1981 The effect of zymosan obtained from various sources was found to be exclusively due to contamination of tee zymosan particles with phospholipase A2 activity.
