Histamine 108-117 PCNA clamp associated factor Homo sapiens 96-99 2862164-0 1985 Cultured endothelial cells synthesize both platelet-activating factor and prostacyclin in response to histamine, bradykinin, and adenosine triphosphate. Histamine 102-111 PCNA clamp associated factor Homo sapiens 43-69 2408682-2 1985 It was found that within the concentration range of 10(-10) to 10(-7) M PAF and its analogs induce a moderate histamine release from the leukocytes. Histamine 110-119 PCNA clamp associated factor Homo sapiens 72-75 2408682-3 1985 However, at higher concentrations (greater than 10(-7) M) PAF induces an enhanced release of histamine from the leukocytes of allergic patients as compared to healthy individuals. Histamine 93-102 PCNA clamp associated factor Homo sapiens 58-61 2408682-4 1985 PAF and its analogs significantly potentiate the allergens-induced release of histamine from the leukocytes of allergic patients. Histamine 78-87 PCNA clamp associated factor Homo sapiens 0-3 2408682-5 1985 It was assumed that PAF induces the expression or demasking of additional numbers of IgE receptors on the surface of basophils, which leads tot he stimulation of histamine release from the leukocytes in the presence of allergens. Histamine 162-171 PCNA clamp associated factor Homo sapiens 20-23 6160567-3 1980 The authors recall the innermost mechanism of the main stages of histamine-release: recognition of membrane receptors, multiple enzymatic activations, opening of calcic membrane pores, synthesis of unpreformed mediators (SRSa and PAF), finally granular extrusion with release of histamine and of numerous mediators, among which the neutrophil chemotactic factor, one of the main responsible ones of the late phase of hypersensitivity phenomena. Histamine 65-74 PCNA clamp associated factor Homo sapiens 230-233 33296106-7 2020 The histamine-1 receptor antagonist rupatadine was developed to have anti-PAF activity, and also inhibits activation of human mast cells in response to PAF. Histamine 4-13 PCNA clamp associated factor Homo sapiens 74-77 33296106-7 2020 The histamine-1 receptor antagonist rupatadine was developed to have anti-PAF activity, and also inhibits activation of human mast cells in response to PAF.

Histamine 88-97 PCNA clamp associated factor Homo sapiens 29-32 24267366-6 2013 RESULTS: PAF stimulated a statistically significant release of histamine, interleukin-8, and tumor necrosis factor (0.001-0.1 mumol/L) that was comparable to that stimulated by substance P. Pretreatment with RUP (25 mumol/L) for 10 minutes inhibited this effect. Histamine 63-72 PCNA clamp associated factor Homo sapiens 9-12 20392487-5 2010 Cell-signaling pathways in PB-derived MCs in response to PAF were investigated by analyzing the effect of various inhibitors and the silencing of phospholipase C (PLC) mRNA on PAF-mediated histamine release. Histamine 189-198 PCNA clamp associated factor Homo sapiens 57-60 20392487-5 2010 Cell-signaling pathways in PB-derived MCs in response to PAF were investigated by analyzing the effect of various inhibitors and the silencing of phospholipase C (PLC) mRNA on PAF-mediated histamine release. Histamine 189-198 PCNA clamp associated factor Homo sapiens 176-179 20392487-6 2010 RESULTS: We show for the first time that PAF induces histamine release from human lung MCs and PB-derived MCs but not skin MCs. Histamine 53-62 PCNA clamp associated factor Homo sapiens 41-44 23320562-1 2013 BACKGROUND: Platelet-activating factor (PAF) causes wheal and flare responses which are abrogated by H1-antihistamines giving rise to the hypothesis that PAF-induced wheal development is secondary to histamine release from dermal mast cells.

Histamine 108-117 PCNA clamp associated factor Homo sapiens 40-43 23320562-1 2013 BACKGROUND: Platelet-activating factor (PAF) causes wheal and flare responses which are abrogated by H1-antihistamines giving rise to the hypothesis that PAF-induced wheal development is secondary to histamine release from dermal mast cells. Histamine 108-117 PCNA clamp associated factor Homo sapiens 154-157 15693702-5 2005 PAF was originally characterized by inducing aggregation and secretion of serotonin and histamine from rabbit platelets. Histamine 88-97 PCNA clamp associated factor Homo sapiens 0-3 10482285-1 1999 The application of platelet-activating factor (PAF) to the nasal mucosa of humans has been shown to increase histamine-induced hyper-reactivity.

Histamine 109-118 PCNA clamp associated factor Homo sapiens 47-50 9155831-0 1997 Platelet-activating factor induces histamine release from human skin mast cells in vivo, which is reduced by local nerve blockade. Histamine 35-44 PCNA clamp associated factor Homo sapiens 0-26 9618706-5 1998 Histamine interacts directly with the endothelial cells (EC) and induces permeability, a transient expression of P-selectin and the secretion of lipid mediators (e.g. PGI2, PAF and LTB4). Histamine 0-9 PCNA clamp associated factor Homo sapiens 173-176 9155831-3 1997 The purpose of this study was to investigate the extent and possible mechanisms of PAF-induced histamine release in human skin in vivo with the use of dermal microdialysis. Histamine 95-104 PCNA clamp associated factor Homo sapiens 83-86 9155831-7 1997 RESULTS: PAF, but not lyso-PAF, caused statistically significant dose-related histamine release and wheal and flare reactions. Histamine 78-87 PCNA clamp associated factor Homo sapiens 9-12 9155831-12 1997 CONCLUSIONS: These data suggest that PAF induced histamine release from mast cells in intact human skin indirectly via neurogenic activation. Histamine 49-58 PCNA clamp associated factor Homo sapiens 37-40 9155831-13 1997 Further, on the intradermal injection of PAF histamine release and the skin responses, the wheal and the flare, are differentially regulated by neurogenic components. Histamine 45-54 PCNA clamp associated factor Homo sapiens 41-44 8872518-6 1996 Our data indicate that oxygen radicals induce a direct calcium independent release of histamine which is due to membrane pertubating processes during the first phase but also induce a specific reaction leading to a further indirect histamine liberation which is probably mediated by PAF. Histamine 232-241 PCNA clamp associated factor Homo sapiens 283-286 8689766-8 1996 The effects of the various antagonists of PAF-induced responses suggest that its effects too may be mediated via histamine, the similarity of the effects of terfenadine and doxepin on these responses indicating that the effects of doxepin may be due to its known antihistamine activity rather than to any specific PAF-antagonistic properties. Histamine 113-122 PCNA clamp associated factor Homo sapiens 42-45 8721524-2 1996 Anti-IgE-stimulated basophil histamine release was significantly reduced in urticaria patients (median 2.9% vs 15.1% in normal controls), whereas histamine release to A23187, FMLP, and PAF, as well as anti-IgE-induced LTC4 release, showed no differences in both groups. Histamine 146-155 PCNA clamp associated factor Homo sapiens 185-188 8689766-15 1996 Previous studies have suggested that the weal and flare response to PAF may be mediated in part by histamine release.

Histamine 146-155 PCNA clamp associated factor Homo sapiens 37-40 7688778-8 1993 Similarly, 1-acyl-2-acetyl-GPC (0.1 to 10 mumol/L) caused a concentration-dependent inhibition of PAF-activated histamine secretion (inhibitory concentration of 50% approximately equal to 0.2 mumol/L). Histamine 112-121 PCNA clamp associated factor Homo sapiens 98-101 1322030-14 1992 The effects of PAF on myocardial function may be due to the activation of mediators (e.g., histamine).

Histamine 78-87 PCNA clamp associated factor Homo sapiens 28-31 8373423-2 1993 We demonstrate that pretreatment of HUVECs with PAF enhances thrombin- or histamine-induced rises of cytosolic free Ca(++)-concentration and subsequent Ca(++)-dependent PGI2-synthesis. Histamine 74-83 PCNA clamp associated factor Homo sapiens 48-51 8373423-4 1993 This suggests cooperative effects of PAF on activation processes induced by thrombin or histamine in HUVECs.

Histamine 19-28 PCNA clamp associated factor Homo sapiens 170-196 1717478-3 1991 EC stimulated with histamine or thrombin coexpress two proadhesive molecules within minutes: granule membrane protein 140 (GMP-140), a member of the selectin family, and platelet-activating factor (PAF), a biologically active phospholipid. Histamine 19-28 PCNA clamp associated factor Homo sapiens 198-201 1711077-3 1991 In this study we examined the effect of PAF upon the release of histamine and leukotriene (LT) C4 by basophils when added alone and in combination with different agonists and cytokines. Histamine 64-73 PCNA clamp associated factor Homo sapiens 40-43 1679658-2 1991 The role of histamine in PAF-induced acute inflammatory responses (flare and weal) in the skin has been evaluated in a series of three separate studies. Histamine 12-21 PCNA clamp associated factor Homo sapiens 25-28 1679658-9 1991 Intradermally injected PAF was associated with acute rises in plasma histamine in blood drawn from a draining vein with peak concentrations occurring within 5 min of injection. Histamine 69-78 PCNA clamp associated factor Homo sapiens 23-26 1679658-14 1991 It is concluded that histamine has an important role in the acute inflammatory responses to intradermally injected PAF, although there does appear to be a significant direct vascular component in the PAF-induced weal response. Histamine 21-30 PCNA clamp associated factor Homo sapiens 115-118 1711077-10 1991 IL-1 beta-pretreated basophils released minimal amounts of histamine in response to PAF. Histamine 59-68 PCNA clamp associated factor Homo sapiens 84-87 1711077-15 1991 Thus, depending on the presence of IL-3, GM-CSF, or IL-5, PAF is a potent basophil agonist capable of inducing histamine release as well as de novo synthesis of LTC4.
