Calcium 150-157 hemolytic complement Mus musculus 77-80 18818727-6 2008 When the model is also used as a tool in the design of experiments, it predicts a synergistic region in the calcium peak height dose response that results when cells are simultaneously stimulated by C5a and UDP. Calcium 108-115 hemolytic complement Mus musculus 199-202 18818727-7 2008 An analysis of the model reveals a potential mechanism for crosstalk between the Galphai-coupled C5a receptor and the Galphaq-coupled UDP receptor signaling systems that results in synergistic calcium release. Calcium 193-200 hemolytic complement Mus musculus 97-100 18559098-6 2008 Likewise, C5a induced intracellular calcium fluxes solely in activated MC. Calcium 36-43 hemolytic complement Mus musculus 10-13 18411281-0 2008 Signaling and cross-talk by C5a and UDP in macrophages selectively use PLCbeta3 to regulate intracellular free calcium. Calcium 111-118 hemolytic complement Mus musculus 28-31 17996333-0 2008 Estrogen enhances expression of the complement C5a receptor and the C5a-agonist evoked calcium influx in hormone secreting neurons of the hypothalamus. Calcium 87-94 hemolytic complement Mus musculus 47-50 17996333-0 2008 Estrogen enhances expression of the complement C5a receptor and the C5a-agonist evoked calcium influx in hormone secreting neurons of the hypothalamus. Calcium 87-94 hemolytic complement Mus musculus 68-71 15255929-2 2004 This correlated to an attenuated calcium signaling of complement (C5a) and purinergic (UTP) receptors as well as to the capacity for effective production of cytokines-chemokines. Calcium 33-40 hemolytic complement Mus musculus 66-69 15983374-6 2005 Similarly, C5a-mediated actin polymerization, C5a- and UTP-stimulated intracellular calcium mobilization, and the stimulation of cAMP formation by isoproterenol were all eliminated in the absence of the Gbeta-subunits. Calcium 84-91 hemolytic complement Mus musculus 46-49 15255929-8 2004 However, both the elevation in basal [Ca2+]i as well as the suppression of C5a- and UTP-evoked calcium signals are selectively and dose-dependently reversed by tyrphostin AG126, a PTK inhibitor that, moreover, blocks inducible nitric oxide and cytokine-chemokine release. Calcium 95-102 hemolytic complement Mus musculus 75-78 14699051-5 2004 Similarly, the C5a-mediated calcium response of single cells is either absent or significantly delayed and weakened by G beta(2) knockdown. Calcium 28-35 hemolytic complement Mus musculus 15-18 8809827-8 1996 The C5a-induced motility reaction was accompanied by an increase in intracellular calcium ([Ca2+]i) as measured by a Fluo-3 based imaging system. Calcium 82-89 hemolytic complement Mus musculus 4-7 1712820-5 1991 Release induced by rC5a was calcium-dependent, and peaked at 30 degrees C. These results indicate that functional heterogeneity exists between the CMC and the PMC of BALB/c mice, that C5a is a relevant stimulus for characterization of this heterogeneity, and that CMC from these animals can serve as a convenient in vitro model for the study of human C5a-mast cell interactions.
