Abstract
Pain is a complex multidimensional concept that facilitates the initiation of the signaling cascade in response to any noxious stimuli. Action potential generation in the peripheral nociceptor terminal and its transmission through various types of nociceptors corresponding to mechanical, chemical or thermal stimuli lead to the activation of receptors and further neuronal processing produces the sensation of pain. Numerous types of receptors are activated in pain sensation which vary in their signaling pathway. These signaling pathways can be regarded as a site for modulation of pain by targeting the pain transduction molecules to produce analgesia. On the basis of their anatomic location, transient receptor potential ion channels (TRPV1, TRPV2 and TRPM8), Piezo 2, acid-sensing ion channels (ASICs), purinergic (P2X and P2Y), bradykinin (B1 and B2), α-amino-3-hydroxy-5- methylisoxazole-4-propionate (AMPA), N-methyl-D-aspartate (NMDA), metabotropic glutamate (mGlu), neurokinin 1 (NK1) and calcitonin gene-related peptide (CGRP) receptors are activated during pain sensitization. Various inhibitors of TRPV1, TRPV2, TRPM8, Piezo 2, ASICs, P2X, P2Y, B1, B2, AMPA, NMDA, mGlu, NK1 and CGRP receptors have shown high therapeutic value in experimental models of pain. Similarly, local inhibitory regulation by the activation of opioid, adrenergic, serotonergic and cannabinoid receptors has shown analgesic properties by modulating the central and peripheral perception of painful stimuli. This review mainly focused on various classes of nociceptors involved in pain transduction, transmission and modulation, site of action of the nociceptors in modulating pain transmission pathways and the drugs (both clinical and preclinical data, relevant to targets) alleviating the painful stimuli by exploiting nociceptor-specific channels and receptors.

Abstract
Peripheral mediators can contribute to the development and maintenance of inflammatory and neuropathic pain and its concomitants (hyperalgesia and allodynia) via two mechanisms. Activation or excitation by these substances of nociceptive nerve endings or fibers implicates generation of action potentials which then travel to the central nervous system and may induce pain sensation. Sensitization of nociceptors refers to their increased responsiveness to either thermal, mechanical, or chemical stimuli that may be translated to corresponding hyperalgesias. This review aims to give an account of the excitatory and sensitizing actions of inflammatory mediators including bradykinin, prostaglandins, thromboxanes, leukotrienes, platelet-activating factor, and nitric oxide on nociceptive primary afferent neurons. Manifestations, receptor molecules, and intracellular signaling mechanisms of the effects of these mediators are discussed in detail. With regard to signaling, most data reported have been obtained from transfected nonneuronal cells and somata of cultured sensory neurons as these structures are more accessible to direct study of sensory and signal transduction. The peripheral processes of sensory neurons, where painful stimuli actually affect the nociceptors in vivo, show marked differences with respect to biophysics, ultrastructure, and equipment with receptors and ion channels compared with cellular models. Therefore, an effort was made to highlight signaling mechanisms for which supporting data from molecular, cellular, and behavioral models are consistent with findings that reflect properties of peripheral nociceptive nerve endings. Identified molecular elements of these signaling pathways may serve as validated targets for development of novel types of analgesic drugs.

Abstract
Abstract
The antinociceptive effect of the limonexic acid isolate of Raulinoa echinata Cowan in four models of pain in mice is described. When evaluated against acetic acid-induced abdominal constrictions, limonexic acid (10, 30 and 60 mg kg−1, i.p.) produced dose-related inhibition of the number of constrictions, with a mean ID50 value of 43 (2.3–79) μmol kg−1, and was more potent than some standard drugs. In the formalin test, limonexic acid inhibited both the first and second phases of formalin-induced pain. Furthermore, the effect was more pronounced in the second phase, with a mean ID50 value of 13.66 (9.35–19.61) μmol kg−1, and had a pharmacological profile that was similar to standard drugs such as acetaminophen and acetyl salicylic acid. Limonexic acid also produced dose-related inhibition of glutamate- and capsaicin-induced pain, with mean ID50 values of 11.67 (8.51–16.0) μmol kg−1 and 47.17 (36.51–60.93) μmol kg−1, respectively. The mechanism of action is not completely understood, but seems to involve direct interaction with the GABAergic and nitroxidergic pathways.

Abstract
This study provides the first evidence that rat epididymis is fully capable of initiating an inflammatory response to lipopolysaccharide (LPS) from Escherichia coli through activation of Toll-like receptor 4 (TLR4). TLR4 functionality was demonstrated by in vivo LPS challenge, which induced a time- and dose-dependent activation of the transcription factor nuclear factor kappa B (NFKB) in caput and cauda epididymides. NFKB activation by LPS in caput epididymidis was abrogated when rats were pretreated with the NFKB inhibitor PDTC, confirming the specificity of this response. Within 2 h of LPS treatment (0.01 and 1 mg/kg, i.v.), NFKB activation in caput and cauda was accompanied by upregulation of Il1b, Nfkbia, and Cd14, but not Tlr4, mRNA. These effects, however, were not sustained after 24 h of LPS treatment. Lipopolysaccharide systemic effects were not restricted to epididymides, since Il1b, Nfkbia, and Cd14 mRNAs were also upregulated in other male reproductive tissues from LPS-treated rats (1 mg/kg, i.v., 2 h). Constitutive TLR4 was immunolocalized in some, but not all, epididymal epithelial cells and in interstitial cells, some of them identified as resident ED2-positive macrophages. No change in TLR4 immunostaining pattern was observed when epididymides from control and LPS-treated rats were compared (1 mg/kg, i.v., 2 h and 24 h). Significant NFKB activation was also achieved within 1 min of in vitro incubation of caput epididymidis with LPS (0.01-5 mug/ml), confirming that components for TLR4 signaling cascade activation are fully active in this tissue. This study contributes to a better understanding of the innate immune response in the epididymis and other tissues from the male reproductive tract.

Abstract
The nocturnal surge of melatonin is the endocrine expression of the circadian system and is essential for organizing the timing of various endogenous processes. Previous works suggest that, in the beginning of a defense response, the increase in circulating tumor necrosis factor-alpha (TNF-alpha) leads to a transient block of nocturnal melatonin production and promotes a disruption of internal time organization. In the present paper, the concentration of melatonin and cytokines [TNF-alpha, interferon-gamma (IFN-gamma), interleukin (IL)-2, IL-4, IL-5, IL-10, IL-12] in the colostrum (postdelivery day 3) and in the milk (postdelivery days 10, 15, 20 and 30) obtained at midday and midnight from mothers who gave birth by vaginal or cesarean section were compared. The nocturnal melatonin surge observed 3 days after vaginal delivery was absent after cesarean section. IL-12 presented no daily variation in either case, while daily variations in IFN-gamma, IL-10, IL-4 and IL-5 were observed after vaginal delivery and cesarean section. On the other hand, the increase in TNF-alpha after cesarean section resulted in suppression of the nocturnal melatonin surge. Daily variation of IL-2 was only observed after recovery of the nocturnal melatonin surge, 30 days after cesarean section. The present paper supports the hypothesis of a cross-talk between the pineal gland and the immune system, which could represent a putative immune-pineal axis.

Abstract
Neuropeptides and kinins are important messengers in the nervous system and--on the basis of their anatomical localisation and the effects produced when the substances themselves are administered, to animals or to human subjects-a significant number of them have been suggested to have a role in pain and inflammation. Experiments in gene deletion (knock-out or null mutant) mice and parallel experiments with pharmacological receptor antagonists in a variety of species have strengthened the evidence that a number of peptides, notably substance P and calcitonin gene-related peptide (CGRP), and the kinins have a pathophysiological role in nociception. Clinical studies with non-peptide pharmacological antagonists are now in progress to determine if blocking the action of these peptides might have utility in the treatment of pain.

Abstract
Pain is a common symptom of injuries and inflammatory-related conditions. The perception of pain, commonly known as nociception, depends on integrated receptors and molecular pathways. Inflammatory mediators are involved in the genesis, persistence, and severity of pain. Noxious stimuli can trigger a cascade of inflammatory loops that feedback onto sensory modalities and domains of the CNS, in an attempt to alert the brain of deregulated homeostasis. Understanding the mechanisms of pain continue to make nociception and hyperalgesia a burgeoning field of research.

Abstract
A large number of data show that melatonin has immunomodulatory properties and is produced by immunocompetent cells; also, some evidence suggests a 'feedback' of the activated immune system on the pineal gland. In this paper, we studied immune-pineal interactions in colostrum obtained from healthy puerperae and mothers with mastitis taking into account that, (a) melatonin levels in milk reflects pineal activity and (b) colostrum quiescent mononuclear and polymorphonuclear phagocytes from healthy mothers in culture are adequate for evaluating the ability of immunocompetent cells to produce melatonin. Here we compared the diurnal and nocturnal melatonin levels in colostrum from healthy puerperae and mothers with mastitis; this is a unique noninvasive model for determining pineal activity in the proinflammatory phase of a defense response. In addition, we determined the 'in vitro' production of melatonin by colostrum immunocompetent cells stimulated by enteropathogenic Escherichia coli or zymosan. Suppression of nocturnal melatonin rise in mothers with mastitis was highly correlated with increased tumor necrosis factor-alpha (TNF-alpha) secretion. This result, interpreted taking into account the presence of the transcription factor nuclear factor kappa B in pineal gland, suggest that the proinflammatory cytokine can inhibit nocturnal pineal melatonin production. On the other hand, stimulated, but not quiescent, immunocompetent cells secreted in the colostrum produced melatonin in vitro. In addition, this production ceases after bacteria killing. These results suggest that during the response to an injury the production of melatonin can be transiently shifted from an endocrine (pineal) to a paracrine (immunocompetent cells) source.

Abstract
It has been well established that neuroinflammation is involved in Alzheimer disease (AD) pathogenesis. Accumulation and aggregation of beta-amyloid (Abeta) peptide in the brains of patients with AD result in activation of glial cells which, in turn, initiates neuroinflammatory responses that involve reactive oxygen intermediates and release of inflammatory cytokines. In this study, bilateral intracerebroventricular (i.c.v.) injections of Abeta (25-35) in the rat resulted in impairment in learning and spatial memory and increased immunoreactive staining of AD-related neuropathological markers (Abeta, APP) and inflammatory mediators (OX-6, COX-2) in CA1 and dentate gyrus regions of the hippocampus. Pyrrolidine dithiocarbamate (PDTC) given intraperitoneally 30 min before Abeta injection and daily for 7 days postsurgery significantly prevented Abeta-induced neuropathological and neuroinflammatory responses, as well as the learning and spatial memory deficits. The potential of PDTC for reducing cognitive and neuropathological deficits may provide preliminary evidence for a new approach of AD treatment.

Abstract
The loss of endothelial function is the initiating factor in the development of diabetic vascular disease. Kinins control endothelial function by the activation of two receptors: the B2 which is constitutively expressed, and the B1 which is highly induced in pathological conditions. In the present study, we observed that the levels of B1-receptor mRNA and protein are induced in endothelial cells incubated in high glucose. An increase in B1-receptor was also observed in the endothelial layer of aortas, from 4-week diabetic rats. When cells were grown in high glucose, the B1 agonist des-Arg9-BK increased nitrite levels, whereas in normal glucose nitrite levels were unchanged. Nitrite increase was blocked by L-NAME and 1400W indicating the participation of the inducible Nitric Oxide Synthase (iNOS). iNOS protein levels were also increased in high glucose. These results demonstrate the participation of the B1 receptor in the signaling pathways mediated by kinins in high glucose.

Abstract
By applying in vivo dimethyl sulphate and UV light type C-footprinting analysis, we previously showed that specific DNA sequences in the -1349/+42 core promoter region of the inducible human BDKRB1 (bradykinin B1 receptor) gene correlated with its transcriptional activity. In the present study we used the highly sensitive DNase I in vivo footprinting approach to delineate more precisely the functional domains of the BDKRB1 gene promoter in human SMCs (smooth muscle cells). Human lymphocytes that do not express a functional BDKRB1 were also studied as a reference using dimethyl sulphate, UV light type C and DNase I treatments. An obvious difference was found in the DNase I-footprinting patterns between cellular systems that express a functional BDKRB1 (SMCs) in comparison with human lymphocytes, where randomly distributed nucleosome-like footprinting patterns were found in the bulk of the core promoter region studied. Gel-shift assays and expression studies pointed to the implication of the YY1 and a TBP/TFIIB (TATA-box-binding protein/transcription factor IIB) transcription factor in the regulation of BDKRB1 gene expression in SMCs and possible YY1 involvement in the mechanisms of nuclear factor kappaB-mediated regulation of the receptor expression. No significant changes in the promoter foot-printing pattern were found after treatment with interleukin-1beta or serum (known BDKRB1 gene inducers), indicating that definite regulatory motifs could exist outside the BDKRB1 gene core promoter region studied.

Abstract
Kinins are proinflammatory peptides that mediate numerous vascular and pain responses to tissue injury. Two pharmacologically distinct kinin receptor subtypes have been identified and characterized for these peptides, which are named B1 and B2 and belong to the rhodopsin family of G protein-coupled receptors. The B2 receptor mediates the action of bradykinin (BK) and lysyl-bradykinin (Lys-BK), the first set of bioactive kinins formed in response to injury from kininogen precursors through the actions of plasma and tissue kallikreins, whereas the B(1) receptor mediates the action of des-Arg9-BK and Lys-des-Arg9-BK, the second set of bioactive kinins formed through the actions of carboxypeptidases on BK and Lys-BK, respectively. The B2 receptor is ubiquitous and constitutively expressed, whereas the B1 receptor is expressed at a very low level in healthy tissues but induced following injury by various proinflammatory cytokines such as interleukin-1beta. Both receptors act through G alpha(q) to stimulate phospholipase C beta followed by phosphoinositide hydrolysis and intracellular free Ca2+ mobilization and through G alpha(i) to inhibit adenylate cyclase and stimulate the mitogen-activated protein kinase pathways. The use of mice lacking each receptor gene and various specific peptidic and nonpeptidic antagonists have implicated both B1 and B2 receptors as potential therapeutic targets in several pathophysiological events related to inflammation such as pain, sepsis, allergic asthma, rhinitis, and edema, as well as diabetes and cancer. This review is a comprehensive presentation of our current understanding of these receptors in terms of molecular and cell biology, physiology, pharmacology, and involvement in human disease and drug development.

Abstract
Kinins are a family of peptides implicated in several pathophysiological events. Most of their effects are likely mediated by the activation of two G-protein-coupled receptors: B(1) and B(2). Whereas B(2) receptors are constitutive entities, B(1) receptors behave as key inducible molecules that may be upregulated under some special circumstances. In this context, several recent reports have investigated the importance of B(1) receptor activation in certain disease models. Furthermore, research on B(1) receptors in the last years has been mainly focused in determining the mechanisms and pathways involved in the process of induction. This was essentially favoured by the advances obtained in molecular biology studies, as well as in the design of selective and stable peptide and nonpeptide kinin B(1) receptor antagonists. Likewise, development of kinin B(1) receptor knockout mice greatly helped to extend the evidence about the relevance of B(1) receptors during pathological states. In the present review, we attempted to remark the main advances achieved in the last 5 years about the participation of kinin B(1) receptors in painful and inflammatory disorders. We have also aimed to point out some groups of chronic diseases, such as diabetes, arthritis, cancer or neuropathic pain, in which the strategic development of nonpeptidic oral-available and selective B(1) receptor antagonists could have a potential relevant therapeutic interest.

Abstract
The bradykinin B1 receptor (B1R) is normally absent under physiological conditions, but is highly inducible during inflammatory conditions or following tissue damage. The present study attempted to determine some of the mechanisms underlying B1R upregulation following tissue injury in rat portal vein. Damage induced by tissue isolation and in vitro incubation caused a significant and time-dependent increase in des-Arg9-bradykinin (des-Arg9-BK) responsiveness that paralleled the B1R mRNA expression, as confirmed by real-time quantitative PCR. In vitro incubation of rat portal vein also induced the activation of some members of the mitogen activated protein kinase (MAPK) family, namely, extracellular signal-regulated kinase (ERK), c-Jun NH2-terminal kinase (JNK), and p38 MAPK, an effect accompanied by degradation of the inhibitory protein IkappaBalpha and translocation of nuclear transcription factor-kappaB (NF-kappaB) to the nucleus. The blockade of p38 MAPK, JNK or NF-kappaB, but not ERK pathways with selective inhibitors, resulted in a significant reduction of the upregulated contractile response caused by the selective B1R agonist des-Arg9-BK, and largely prevented the induction of B1R mRNA expression in the rat portal vein. Together, these results demonstrate that in vitro tissue damage induces activation of several intracellular signaling pathways that have a key role in the control of B1R expression. B1R could exert a pivotal role in the development of the cardiovascular response associated with vascular damage.

Abstract
1. The present study evaluated the ability of the administration of platelet activating factor (PAF) to induce the upregulation of B(1) receptors in the rat paw. 2. Local treatment with PAF resulted in a time-dependent increase of oedema formation induced by the B(1) receptor agonist des-Arg(9)-BK (des-Arg(9)-bradykinin), but not by the B(2) receptor agonist tyrosine(8)-bradykinin. Functional upregulation of B(1) receptors was accompanied by a prominent increase of B(1) receptor mRNA expression in the rat paw. 3. In PAF-treated paws, des-Arg(9)-BK-induced oedema formation was significantly inhibited by the B(1) receptor antagonists des-Arg(9)-[Leu(8)]-BK and R-715. The effects of PAF pretreatment were receptor operated, as assessed by the effects of the PAF receptor antagonist WEB2086 or by desensitisation of PAF receptors. 4. The protein synthesis inhibitor cycloheximide, the anti-inflammatory steroid dexamethasone or the nuclear factor (NF-kappaB) blockers pyrrolidine-dithiocarbamate (PDTC) and Nalpha-tosyl-L-chloromethylketone significantly blocked the functional upregulation of B(1) receptors. 5. The selectin inhibitor fucoidin, an anti-CD18 antibody or an anti-rat neutrophil antiserum, also significantly prevented des-Arg(9)-BK-induced paw oedema in rats pretreated with PAF. 6. Intradermal injection of PAF induced a 25-fold increase of myeloperoxidase activity in the rat paw, a response that was significantly inhibited by fucoidin, anti-CD-18, anti-rat neutrophil antiserum or PDTC. 7. Local treatment with PAF also resulted in a marked increase of NF-kappaB activation, an effect largely prevented by PDTC or by the anti-rat neutrophil antiserum. 8. Collectively, the present results indicate that the induction of B(1) receptors following treatment with the chemotatic mediator PAF is dependent on the recruitment of neutrophils, an event that is under the control of adhesion molecules, protein synthesis and NF-kappaB activation. These findings provide new insights into the role played by cell migration and chemotatic factors on B(1) receptor upregulation in vivo.

Abstract
1 This study examines the involvement of kinins in neutrophil migration into rat subcutaneous air pouches triggered by lipopolysaccharide (LPS), as well as the putative roles played by kinin B(1) and B(2) receptors, tumour necrosis factor alpha (TNF-alpha), interleukin-1 beta (IL-1beta) and selectins in this response. 2 LPS (5 ng to 10 micro g cavity(-1)) injected into the 6-day-old pouch induced a dose- and time-dependent neutrophil migration which peaked between 4 and 6 h, and was maximal following the dose of 100 ng cavity(-1) (saline: 0.46+/-0.1; LPS: 43+/-3.70 x 10(6) cells cavity(-1) at 6 h). 3 Bradykinin (BK) (600 nmol) injected into the pouch of saline-treated rats induced only modest neutrophil migration (0.73+/-0.16 x 10(6) cells cavity(-1)). A more robust response to BK (3.2+/-0.25 x 10(6) cells cavity(-1)) was seen in animals pretreated with captopril, but this was still smaller than the responses to IL-1beta or TNF-alpha (15 pmol: 23+/-2.2 x 10(6) and 75 pmol: 29.5+/-2 x 10(6) cells cavity(-1), respectively). Nevertheless, the B(1) agonist des-Arg(9)-BK (600 nmol) failed to induce neutrophil migration. 4 HOE-140 (1 and 2 mg kg(-1)), a B(2) receptor antagonist, reduced LPS-induced neutrophil migration. HOE-140 also reduced the neutrophil migration induced by BK, but had no effect on the migration promoted by IL-1beta or TNF-alpha. des-Arg(9)-[Leu(8)]-BK, B(1) receptor antagonist was ineffective in changing neutrophil migration caused by any of these stimuli. 5 Neutrophil migration induced by LPS or BK was reduced by interleukin-1 receptor antagonist (IL-1ra) (1 mg kg(-1)), sheep anti-rat TNF serum (anti-TNF serum) (0.3 ml cavity(-1)), and the nonspecific selectin inhibitor fucoidin (10 mg kg(-1)). 6 TNF-alpha levels in the pouch fluid were increased by LPS or BK injection, peaking at 0.5-1 h and gradually declining thereafter up to 6 h. IL-1beta levels increased steadily throughout the 6 h period. HOE-140 markedly inhibited the rise in IL-1beta and TNF-alpha levels in pouch fluid triggered by both stimuli. 7 These results indicate that BK participates importantly in selectin-dependent neutrophil migration into the air pouch triggered by LPS in the rat, by stimulating B(2) receptors coupled to synthesis/release of TNF-alpha and IL-1beta.

Abstract
1 The function and autoradiographic binding expression of kinin B(1) receptors were evaluated in the lungs of Streptozotocin (STZ)-diabetic rats. 2 The intrapleural injection (i.pl.) of des-Arg(9)-bradykinin (des-Arg(9)-BK) (50 and 100 nmol per site), a selective B(1) receptor agonist, increased time-dependently the mononuclear and neutrophil cells influx in the pleural cavity of rats treated with STZ (65 mg kg(-1), i.p., 4 days earlier). This effect was significantly less in control rats. 3 The influx of mononuclear and polymorphonuclear neutrophil cells induced by des-Arg(9)-BK was significantly inhibited by two B(1) receptor antagonists (des-Arg(10)-Hoe140 or R-715, 100 nmol per site, 5 min earlier), but not by two B(2) receptor antagonists (Hoe140, 10 nmol or NPC 18884, 100 nmol per site, 5 min earlier). However, Hoe140 prevented the higher basal leukocyte influx seen in STZ-diabetic rats. 4 Leukocyte infiltration induced by des-Arg(9)-BK in STZ-diabetic rats was significantly reduced after treatment with insulin (2 U per day, s.c. over 4 days) or with an anti-PMN antibody (0.1 ml of a 1 : 20 dilution, i.pl. 5 min earlier). 5 Specific B(1) receptor binding sites were seen in lung sections from both control and STZ-diabetic rats, yet the density of labelling was much greater in diabetic rats and particularly after intrapleural injection of des-Arg(9)-BK. Treatment with insulin or with the anti-PMN antibody markedly reduced B(1) receptor binding sites occurring after the injection of des-Arg(9)-BK in STZ-diabetic rats. 6 Data suggest that the B(1) receptor is up-regulated in the lungs of STZ-diabetic rats, and its activation increases leukocyte infiltration into the pleural cavity. The overexpression of B(1) receptors seems to depend on neutrophils influx and appears to be associated with hyperglycaemia.

Abstract
Two types of receptors (B1R, B2R) for kinins are defined in mammalian species. Comparative experiments involving recombinant fusion proteins consisting of rabbit B1R or B2R fused to GFP-related proteins are exploited to study the regulation of the response to kinins at the receptor level. The following points will be briefly reviewed and supported by some novel data. (1) The constitutive B2Rs are internalized upon agonist stimulation, but completely recycled to the cell surface; however, B2R destruction can be achieved following limited proteolysis (extracellular trypsin, neutrophil proteases), a plausible down-regulation mechanism in pathology. (2) The inducible B1Rs, stimulated by des-Arg9-kinins, are not phosphorylated nor internalized upon agonist stimulation, but rather undergo a reversible redistribution to caveolae-related rafts. B2Rs are also subjected to this translocation, but only transiently (before endocytosis). (3) Based on the analysis of rabbit aortic smooth muscle cells, B1R induction by cytokines is dependent on nuclear factor KB in rabbit vascular tissue, but exogenous kinins acting on either receptor type do not induce B1R expression.

Abstract
Kinin B(1) receptor (B(1)R) expression and the importance of the transcription factor nuclear factor (NF)-kappa B in this process were evaluated in models based on the rabbit aorta: freshly isolated tissue (postisolation induction) and cultured smooth muscle cells (SMCs). A 3-h incubation of freshly isolated tissues determined a sharp B(1)R mRNA increase (RT-PCR). Coincubation of tissues with a stimulus (interleukin-1 beta, fetal bovine serum, epidermal growth factor, or cycloheximide) further increased mRNA levels. Cultured SMCs possessed a basal population of surface B(1)Rs ([(3)H]Lys-des-Arg(9)-bradykinin binding) that was upregulated by treatments with the same set of stimuli (binding, mRNA, nuclear runon). Pharmacological inhibitors of NF-kappa B (MG-132, BAY 11-7082, dexamethasone) or actinomycin D reduced the postisolation induction of B(1)Rs in fresh aortic tissue (contractility or mRNA) and the cytokine effect on cells (mRNA, binding). NF-kappa B may be a common mediator of various stimuli that increase B(1)R gene transcription in the rabbit aorta, including tissue isolation, but cycloheximide also stabilizes B(1)R mRNA. The SMC models faithfully mimic the in vivo situation with regard to B(1)R regulation.

Abstract
This short review focuses on the most recent findings in the rapidly expanding field of kinin research. Through a series of recent publications, the crucial relevance of this group of peptides as mediators of inflammatory pain is becoming increasingly evident. On the strength of this idea, kinins have been implicated as algogen peptides produced in response to noxious stimuli. The importance of kinins has been elucidated by different pharmacological and molecular approaches. Special attention has been given to studies with selective kinin antagonists, as well as to the use of receptor gene deletion technology. The gathering of results has demonstrated that both B(1) and B(2) receptors seem to exert a meaningful role during nociceptive responses, the B(1) receptor being most relevant in the chronic stages of inflammatory pain. It is hoped that new effective and useful therapeutic agents, mainly B(1) kinin selective receptor antagonists, might soon be available.
