Histamine 88-97 complement C3 Homo sapiens 31-34 7513741-1 1994 The complement peptides C3a and C5a have been shown previously to release histamine from human basophils but not human lung mast cells. Histamine 74-83 complement C3 Homo sapiens 24-27 7513741-3 1994 In concentration-response studies, both C3a and C5a released histamine in a concentration related manner with C5a being 40-50 times more potent. Histamine 61-70 complement C3 Homo sapiens 40-43 7513741-7 1994 In time-course studies, histamine release induced by C3a and C5a was complete within 15 seconds. Histamine 24-33 complement C3 Homo sapiens 53-56 7513741-10 1994 Both C3a and C5a at concentrations that induced 10-16% net histamine release caused a negligible release of the newly generated mediator, PGD2. Histamine 59-68 complement C3 Homo sapiens 5-8 7513741-12 1994 However, the activation site for C3a and C5a appears to be different to that for substance P as the substance P antagonist (D-Pro4, D-Trp7,9,10) SP4-11 inhibited histamine release stimulated by substance P but not that induced by C3a and C5a. Histamine 162-171 complement C3 Homo sapiens 33-36 1373170-1 1992 Incubation of either C3a, C3ades Arg, or synthetic analogues of the C-terminal sequence of C3a with purified rat peritoneal mast cells resulted in a rapid and dose-dependent histamine release. Histamine 174-183 complement C3 Homo sapiens 21-24 7679650-3 1993 When incubated with IL-3, these cells specifically liberated histamine on C3a stimulation. Histamine 61-70 complement C3 Homo sapiens 74-77 1282507-7 1992 Studies with the anaphylatoxin, C3a, and its analogues 21R and C3ades Arg on skin mast cells emphasized the importance of basic amino acids for histamine-liberating peptides. Histamine 144-153 complement C3 Homo sapiens 32-35 1373170-1 1992 Incubation of either C3a, C3ades Arg, or synthetic analogues of the C-terminal sequence of C3a with purified rat peritoneal mast cells resulted in a rapid and dose-dependent histamine release. Histamine 174-183 complement C3 Homo sapiens 26-29 6170591-3 1981 Chemically purified human C3a and C5a each caused histamine release from human basophils; C5a was more potent than C3a. Histamine 50-59 complement C3 Homo sapiens 26-29 1375610-6 1992 net histamine release, 20-30%) in a dose-related, temperature- and time-dependent fashion following stimulation with purified human C5a and C3a (over the ranges of 5 x 10(-8) M to 10(-7) M and 3 x 10(-7) M to 6 x 10(-6) M, respectively). Histamine 4-13 complement C3 Homo sapiens 140-143 1697689-5 1990 However, when basophils were pretreated with IL-3 at concentrations of only 0.01-1 unit/ml, they became responsive to C3a, releasing large amounts of histamine and also generating leukotrienes. Histamine 150-159 complement C3 Homo sapiens 118-121 1697689-8 1990 C3a-induced histamine release and leukotriene generation occurred rapidly in IL-3-primed cells, being complete after 0.5 and 2 min, respectively. Histamine 12-21 complement C3 Homo sapiens 0-3 3026724-1 1986 Anaphylatoxins, in particular C3a and C5a, have various biological activities which suggest a role as mediators of inflammatory reactions: they cause contraction of smooth muscle, histamine release, increase in capillary permeability, adhesion of leukocytes to vascular endothelium, leukocyte chemotaxis, and aggregation of platelets and leukocytes. Histamine 180-189 complement C3 Homo sapiens 30-33 3871207-6 1985 Histamine was found to partially mediate the vascular leakage induced by C3a and the initial (first 5 min) permeability response to the high concentration of C5a, whereas the subsequent leakage induced by the latter anaphylatoxin was unaffected by mepyramine pretreatment. Histamine 0-9 complement C3 Homo sapiens 73-76 2579381-3 1985 As a function of dose, C3a caused tachycardia, impairment of atrioventricular conduction, left ventricular contractile failure, coronary vasoconstriction, and histamine release. Histamine 159-168 complement C3 Homo sapiens 23-26 2579381-5 1985 The magnitude of C3a-induced tachycardia correlated with the amount of endogenous cardiac histamine released into the coronary effluent. Histamine 90-99 complement C3 Homo sapiens 17-20 2579381-7 1985 This suggests that histamine, leukotrienes, and vasoactive prostanoates may mediate the various cardiac effects of C3a. Histamine 19-28 complement C3 Homo sapiens 115-118 7047077-4 1981 Cleavage of C3 and C5 by either pathway yields the C3a and C5a anaphylatoxins which cause histamine release from mast cells and formation of the C5b6789 attack complex causes cell lysis. Histamine 90-99 complement C3 Homo sapiens 51-54 6170591-5 1981 The addition of C3a and C5a at suboptimal concentrations produced an additive effect of histamine release. Histamine 88-97 complement C3 Homo sapiens 16-19 89118-2 1979 On a molar basis, 5R was one-tenth and 8R was one-fifth as active as C3a in causing histamine release. Histamine 84-93 complement C3 Homo sapiens 69-72 7350527-1 1980 Investigation of the biological effects of the cleavage product, C3a, derived from the third component of complement has generally focused on the effects it exerts as an anaphylatoxin, that is, smooth muscle contraction and histamine release from mast cells and basophils. Histamine 224-233 complement C3 Homo sapiens 65-68 7011615-3 1980 Using immunofluorescence and pulse-label studies with 3H-labelled amino acids, histamine was shown to inhibit the secretion of newly synthesized C2, C4, C3, factor B and beta 1H globulin by monocytes in culture. Histamine 79-88 complement C3 Homo sapiens 153-165 7011615-5 1980 The observations that all monocytes in cultures containing histamine stained for C2, C4, and C3, factor B and beta 1H, when secretion was impaired, shows that all monocytes synthesize these proteins. Histamine 59-68 complement C3 Homo sapiens 93-105 7011615-7 1980 The anaphylotoxins, C3a and C5a, formed as a result of C3 and C5 cleavage, release histamine from mast cells and basophils. Histamine 83-92 complement C3 Homo sapiens 20-23 7011615-8 1980 Histamine, by inhibiting the production of C4, C2, and C3 and factor B by mononuclear phagocytes, inhibits further C3 and C5 cleavage by restricting the formation of C42, C423b and C3bBbP. Histamine 0-9 complement C3 Homo sapiens 55-70 30032131-9 2018 Our data suggests that down-regulation of C3aR expression by mediators present in allergic situations such as IL-4 or histamine has an anti-inflammatory impact by reducing the sensitivity to C3a-induced down-stream signaling, thereby contributing to the regulation of local inflammatory responses in the skin. Histamine 118-127 complement C3 Homo sapiens 42-45 109469-2 1979 Release of histaminase, one of two important histamine catabolizing enzymes, and beta-glucuronidase from polymorphonuclear leukocytes was solely dependent on particle-bound C3b (the larger cleavage product of the third component of complement) when fluid-phase complement was excluded. Histamine 45-54 complement C3 Homo sapiens 173-176 48505-2 1975 The peptides, derived from human or porcine complement proteins C3 and C5, were less potent than 48/80 but more potent than bradykinin in stimulating release of histamine from mast cells. Histamine 161-170 complement C3 Homo sapiens 64-73 803505-15 1975 Porcine C3a, like human C3a, was shown to contain a COOH-terminal arginyl residue essential for smooth muscle contraction and for induction of histamine release from mast cells. Histamine 143-152 complement C3 Homo sapiens 8-11 4097977-14 1970 These observations were consistent with the endogenous production of C3a and the resulting histamine release from mast cells. Histamine 91-100 complement C3 Homo sapiens 69-72 22155625-2 2012 C4a also inhibited histamine release from HMC-1 cells that were induced by recombinant C3a. Histamine 19-28 complement C3 Homo sapiens 87-90 24493825-8 2014 PBdMC released >10% histamine upon stimulation with anti-IgE, C3a, Substance P, and Compound 48/80, whereas CBdMC only reacted to C3a. Histamine 23-32 complement C3 Homo sapiens 65-68 26120516-7 2014 C5a and C3a cause the in vitro release of histamine and tryptase from HHMC. Histamine 42-51 complement C3 Homo sapiens 8-11 12612546-4 2003 C3a- and C5a-induced thromboxane (TXB2) generation and histamine release from HMC-1 cells and whole-blood basophils were also suppressed by exogenous immunoglobulins. Histamine 55-64 complement C3 Homo sapiens 0-3 18039528-8 2007 Finally, because C3a and C5a can stimulate the generation of nitric oxide along with the secretion of histamine and LTC4 from several cell types, the anaphylatoxins can bring about an increase in vascular permeability that facilitates eosinophil accumulation at sites of allergic inflammation. Histamine 102-111 complement C3 Homo sapiens 17-20 9585825-5 1998 It has been proved in vitro that aqueous extracts of some allergens produce the consumption of complement, by its usual via, in which the C1 component is involved, without the mediation of antibodies, generating anaphylotoxin C3a, which is a powerful releaser of histamine, as well as C3b, which participates in the regulation of the cellular immunitary system.
