Activation of B2 bradykinin receptors by neurotensin
Cellular Signalling, 2003Many previous reports suggested that relatively high concentrations of neurotensin were required to exert its effects on neurotransmitter secretion. The neurotensin binding sites, which recognize high concentrations of neurotensin, were characterized in rat pheochromocytoma (PC12) cells. When PC12 cells were treated with neurotensin, [3H]norepinephrine

The Bradykinin B2-Receptor in Human Decidua
Seminars in Thrombosis and Hemostasis, 1999Bacterial infection of the amniotic cavity is one of the most frequent causes of preterm delivery. Bacterial products activate a network of autocrine and paracrine mediators in fetal membranes and decidua, with prostaglandins finally inducing contractions of the myometrium. Bradykinin and its B2-receptor (B2R) seem to be part of this network.

Regulation of Bradykinin Action at the Receptor Level
Journal of Cardiovascular Pharmacology, 1990Intact cultured human foreskin fibroblasts can be used as an in vitro system to study the regulatory events related to kinin receptor function. Specific bradykinin (BK) receptor sites (B2 subtype) were measured by direct binding study and correlated with BK-induced biological effects such as the release of inositol phosphates, formation of prostacyclin

Differential Contribution of Bradykinin Receptors in Angiogenesis
2000Bradykinin (BK) contributes to the inflammatory response inducing vasodilation of postcapillary venules and has been demonstrated to induce neovascular growth in subcutaneous rat sponges. In this study the ability of BK to stimulate cell growth and migration in cultured endothelium from coronary postcapillary venules (CVEC) has been investigated.

Advances in the Development of Bradykinin Receptor Ligands
Current Topics in Medicinal Chemistry, 2006Kinins are blood-derived local-acting peptides that elicit specific cellular effects via the stimulation of two related G protein coupled receptors. While the B(2)receptor subtype, constitutively expressed in various tissues, is believed to mediate most of the physiological actions of kinins in healthy conditions, the B(1) receptor, highly regulated ...

Bradykinin receptor types and B2 subtypes
Life Sciences, 1994Bradykinin, desArg9BK, some agonist analogues and several antagonists have been tested in isolated organs in order to identify bradykinin B2 receptor subtypes. The initial pharmacological characterization was made in the rabbit jugular vein and the guinea pig ileum, two widely used B2 preparations which have shown marked differences in their ...

Expression and function of bradykinin receptors in microglia
Life Sciences, 2003Expression of bradykinin (BK) receptors and their cellular function were investigated in microglia. Microglial cells were isolated from mixed cultures of cerebrocortical cells from postnatal day 3 Wistar rats. Reverse transcription-PCR (RT-PCR) showed that rat primary microglia express mRNAs for the type 2 bradykinin (B(2)) receptor subtype but not the

Recent developments in the understanding of bradykinin receptors
Life Sciences, 1992The dramatic activities of bradykinin and related peptides as mediators of pain, inflammation and hypotension have been intensely studied for several decades. More recently, the involvement of bradykinin in regulation of ion transport by epithelia, hormone release from endocrine organs, energy metabolism, tissue growth, and leukocyte activation have ...

Characterization of bradykinin receptors in peripheral organs
Canadian Journal of Physiology and Pharmacology, 1991Bradykinin (BK) and related kinins are potent stimulants of the rabbit jugular vein, the hamster urinary bladder, and the guinea pig trachea. The characterization of kinin receptors in these tissues was made with agonists and antagonists. Results obtained with agonists indicate that bradykinin and kallidin are much more active than des-Arg9-BK and ...

Bradykinin receptors in isolated rat duodenum
Peptides, 1990Pharmacological properties of the bradykinin receptors in the isolated rat duodenum were investigated by examining the relaxant and contractile responses to bradykinin and [des-Arg9]-bradykinin, an agonist of B1 receptors. A specific desensitization and de novo formation for B1 receptors were observed.
