de Mora F, Messlinger K. Is calcitonin gene-related peptide (CGRP) the missing link in food histamine-induced migraine? A review of functional gut-to-trigeminovascular system connections. Drug Discov Today 2024; 29:103941. [PMID: 38447930 DOI: 10.1016/j.drudis.2024.103941] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 02/21/2024] [Accepted: 02/29/2024] [Indexed: 03/08/2024]
Abstract
Calcitonin gene-related peptide (CGRP) and histamine plasma concentrations increase during migraine attacks. Both mediators are potent vasodilators, and they have been shown to reciprocally contribute to the release of each other in the trigeminovascular system, possibly driving migraine development. A high-histamine-content diet triggers migraine in patients who have histamine degradation deficiency owing to diaminooxidase (DAO) gene mutations. Therefore, studying functional links between exogenous histamine and CGRP seems promising for the understanding of diet-induced migraine generation. Notably, there is a lack of knowledge about the interplay of the enteric nervous system and the spinal/trigeminal somatosensory system with regard to CGRP and histamine. Based on background evidence, we propose that a functional interconnection between exogenous histamine and CGRP contributes to migraine development.

Abstract
This review addresses pharmacological, structural and functional relationships among H2-histamine receptors and H1-histamine receptors in the mammalian heart. The role of both receptors in the regulation of force and rhythm, including their electrophysiological effects on the mammalian heart, will then be discussed in context. The potential clinical role of cardiac H2-histamine-receptors in cardiac diseases will be examined. The use of H2-histamine receptor agonists to acutely increase the force of contraction will be discussed. Special attention will be paid to the potential role of cardiac H2-histamine receptors in the genesis of cardiac arrhythmias. Moreover, novel findings on the putative role of H2-histamine receptor antagonists in treating chronic heart failure in animal models and patients will be reviewed. Some limitations in our biochemical understanding of the cardiac role of H2-histamine receptors will be discussed. Recommendations for further basic and translational research on cardiac H2-histamine receptors will be offered. We will speculate whether new knowledge might lead to novel roles of H2-histamine receptors in cardiac disease and whether cardiomyocyte specific H2-histamine receptor agonists and antagonists should be developed.

Abstract
Background Dilatation of cranial vessels has been proposed as a part of the cascade that initiates an episode of migraine. This is based on the observation that intravenous administration of several substances with vasodilator properties can trigger migraine-like symptoms in migraineurs. Methods We used in vitro myography of human cerebral arteries and in vitro pressurized arteriography of rat middle cerebral artery (MCA) to evaluate the vasomotor responses of cerebral arteries to increasing concentrations of vasoactive substances used to elicit migraine-like attacks. Results All substances except carbachol induced a strong vasodilatory response when applied to the abluminal side of a rat MCA but negligible response when applied to the luminal side. Luminal carbachol gave a strong dilatory response but a weak response at the abluminal side. The prostaglandins PGE2 and epoprostenol constricted the rat MCA while human cerebral arteries relaxed. The pEC50 of carbachol, histamine, epoprostenol, VIP and sildenafil differed significantly between cerebral arteries from man and rat. The differences in pEC50 for SNP, αCGRP, PACAP-27 and PACAP-38 were not significant between the species. PGE2 had no noticeable effect on human arteries in vitro. Conclusion All tested substances with the exception of VIP and carbachol have been found to elicit migraine-like attacks in migraineurs. Since these two agents have vasodilatory effects in humans, it suggests that vasodilatation is not the only reason for eliciting a migraine-like attack in migraineurs. In addition, there are significant species differences that show the importance of performing experiments in human vessels.

Abstract
Migraine is the most common neurological disorder, and much has been learned about its mechanisms in recent years. However, the origin of painful impulses in the trigeminal nerve is still uncertain. Despite the attention paid recently to the role of central sensitisation in migraine pathophysiology, in our view, neuronal hyperexcitability depends on activation of peripheral nociceptors. Although the onset of a migraine attack might take place in deep-brain structures, some evidence indicates that the headache phase depends on nociceptive input from perivascular sensory nerve terminals. The input from arteries is probably more important than the input from veins. Several studies provide evidence for input from extracranial, dural, and pial arteries but, likewise, there is also evidence against all three of these locations. On balance, afferents are most probably excited in all three territories or the importance of individual territories varies from patient to patient. We suggest that migraine can be explained to patients as a disorder of the brain, and that the headache originates in the sensory fibres that convey pain signals from intracranial and extracranial blood vessels.

Abstract
Salient aspects of the anatomy and function of the blood-barrier barrier (BBB) are reviewed in relation to migraine pathophysiology and treatment. The main function of the BBB is to limit the access of circulating substances to the neuropile. Smaller lipophilic substances have some access to the central nervous system by diffusion, whereas other substances can cross the BBB by carrier-mediated influx transport, receptor-mediated transcytosis and absorptive-mediated transcytosis. Studies of drugs relevant to migraine pathophysiology and treatment have been examined with the pressurized arteriography method. The drugs, given both luminally and abluminally, provide important notions regarding antimigraine site of action, probably abluminal to the BBB. The problems with the BBB in animal models designed to study the pathophysiology, acute treatment models and preventive treatments are discussed with special emphasize on the triptans and calcitonin gene-related peptide (CGRP). The human experimental headache model, especially the use of glycerol trinitrate (the nitric oxide model), and experiences with CGRP administrations utilize the systemic administration of the agonists with effects on other vascular beds also. We discuss how this can be related to genuine migraine attacks. Our view is that there exists no clear proof of breakdown or leakage of the BBB during migraine attacks, and that antimigraine drugs need to pass the BBB for efficacy.

Abstract
Functional serotonin (5-HT) and histamine receptor subtypes were investigated in porcine middle cerebral and ciliary arteries. An H(1) antagonist, mepyramine, antagonized histamine-induced responses with pK(B) values of 8.91-9.10. In the presence of 1 muM mepyramine, however, histamine caused dilation through H(2) receptors in the middle cerebral but not in the ciliary artery. A 5-HT(2A) antagonist, ketanserin, antagonized 5-HT-induced responses, causing rightward shifts in the concentration-response curves with pK(B) values of 8.52-8.71. A 5-HT(1B) antagonist, SB224289, produced rightward shifts of the concentration-response curves to sumatriptan with pK(B) values (6.66) only in the middle cerebral artery. In contrast, a 5-HT(1D) antagonist, BRL15572, had no effect in either artery. An RT-PCR study demonstrated the gene expression of the mRNAs of all three receptors (5HT(1B), 5HT(1D) and 5HT(2A)) in both arteries. These results suggest that histamine-induced contraction is mediated only through functional H(1) receptor in these arteries. Interestingly, there are functional 5-HT(2A) and 5-HT(1B) receptor subtypes in the middle cerebral artery, whereas the only functional receptor is 5-HT(2A) in the ciliary artery. The difference may be important for treatment with 5-HT(1B/1D) agonists (e.g. for migraine) without ocular side effect.

Abstract
Histamine-induced contraction and its potentiation by neuropeptide Y were investigated in rat blood vessels. Rat arteries and veins constricted with single concentrations of histamine dose-dependently (0.1-100 microM). This histamine-induced contraction immediately desensitized. Histamine H1 receptor antagonists, 1 microM mepyramine and 1 microM diphenhydramine, abolished this transient contraction completely, whereas cimetidine, phentolamine, reserpine and tetrodotoxin failed to inhibit the contraction. Histamine H1 receptor mRNA level by reverse transcription-polymerase chain reaction was quite parallel to histamine H1 receptor-mediated contraction, indicating that the contraction is mediated through histamine H1 receptors in the smooth muscle. Neuropeptide Y (10 nM in arteries and 3 nM in veins, respectively) significantly potentiated histamine H1 receptor-mediated contraction via neuropeptide Y1 receptors in most of rat blood vessels. Since the phospholipase C inhibitors, neomycin (1 mM) and 2-nitro-4-carboxyphenyl-N, N-diphenylcarbamate (NCDC, 10 microM), respectively, specifically abolished the potentiation, the potentiation by neuropeptide Y may depend on activation of phospholipase C.

Abstract
The routine availability of murine models of various cerebral circulatory disorders requires characterization of the regulation of cerebral artery tone in the mouse. Using vasoconstrictors and vasodilators with known efficacy in the cranial circulation of other species, we determined the pharmacological properties of the isolated pressurized mouse middle cerebral artery (MCA). The maximal pressure-induced myogenic constriction in isolated mouse MCA was 20.6+/-2.4%. Inhibition of nitric oxide (NO) and endothelin-1 (ET-1) altered the extent of pressure-induced myogenic tone. Isolated mouse MCA failed to either constrict or relax to 5-hydroxytryptamine (5-HT) and histamine; other vasoconstrictors demonstrated the following rank order of efficacy: ET-1>phenylephrine>U-46619. The rank order of endothelium-dependent vasodilator efficacy was bradykinin (BK)>acetylcholine (ACh)>substance P. The constriction produced by phenylephrine (PE) required a smaller increase in intracellular Ca(2+) elevation compared to constriction of a similar magnitude produced by membrane depolarization with potassium chloride (KCl). Pressure-induced myogenic tone (20-80 mm Hg) in mouse MCA was associated with smooth muscle cell membrane depolarization (-52.6+/-0.9 to -37.3+/-1.75 mV). Pressure-induced myogenic tone occurred with a smaller change in membrane potential compared to tone of a similar magnitude produced with KCl (-43.37+/-2.66 vs. -29.47+/-1.05 mV). The mouse MCA has a pharmacological profile that is distinct from other species including humans; however, similar to findings in other cerebral arteries, the mouse MCA shows intracellular sensitization to Ca(2+) following receptor activation.

Abstract
The pain of migraine is often throbbing suggesting an important role for the cranial blood vessels and their innervation by the trigeminal nerve. It is proposed that clinically effective anti-migraine compounds, such as 5-HT(1B/1D) agonists, have actions that include inhibiting calcitonin gene-related peptide (CGRP) release from trigeminal nerves. Human studies suggest that histamine can induce migraine possibly by activating nitric oxide (NO) synthase to promote endogenous NO production. The present studies investigated the effect of histamine and its antagonists on the cranial blood vessels using intravital microscopy to assess directly the diameter of dural arteries in sodium pentobarbitone anaesthetised rats. Electrical stimulation of a closed cranial window produces, by local depolarisation of nerves, dural vessel dilation that is monitored continuously on-line using video-microscopy and a video dimension analyser. Histamine infusion caused immediate and reproducible dilation of meningeal blood vessels (103.5+/-6%; n=40) that could be blocked by H(1)- (mepyramine) and H(2) (famotidine)-receptor antagonists (P<0.05), as well as a nitric oxide synthase inhibitor (N(G)-nitro-L-arginine methylester; P<0.05). Neurogenic dural vasodilation was not inhibited by H(2)-receptor antagonists, but was significantly inhibited by a H(1)-receptor antagonist at the high dose of 10 mg/kg. The present studies demonstrate that histamine is likely to activate NO synthase to promote NO production. There is also evidence that H(1)-receptors may be present on trigeminal neurones as the H(1)-receptor antagonist inhibited neurogenic vasodilation, albeit at a large dose.

Abstract
Responses to hypercapnia and acetylcholine by newborn piglet pial arterioles are prostanoid dependent but appear to require both prostanoids and nitric oxide in juvenile pigs. We hypothesized that cerebrovascular dilatory responses become less prostanoid dependent and more NO dependent with development. Pial arteriolar responses to hypercapnia and histamine were recorded from alpha-chloralose-anesthetized newborn and juvenile pigs with closed cranial windows. Responses were recorded during control, after indomethacin or N(omega)-nitro-L-arginine (L-NNA), and after inhibitor plus iloprost or sodium nitroprusside. Indomethacin blocked newborn hypercapnic responses and markedly attenuated histamine dilations, but only reduced the dilations to about half in juveniles. Iloprost at subdilator concentrations restored newborn responses to hypercapnia and histamine but did not alter either response in indomethacin-treated juveniles. L-NNA attenuated juvenile, but not newborn, hypercapnia-induced dilations. Sodium nitroprusside did not restore the response. L-NNA did not alter responses to histamine in either age group. Cerebrovascular dilations to hypercapnia and histamine are prostanoid dependent and nitric oxide independent in the newborn pig, whereas nitric oxide assumes an increasing role in hypercapnic, but not histamine, responses with development.

Abstract
The involvement of histamine-receptor subtypes in histamine-induced release of nitric oxide (NO) from porcine aortic endothelial cells was studied. NO release was measured directly by using an NO electrode and by electron paramagnetic resonance (EPR) spin trapping. NO release induced by histamine (200 microM) was reduced in the presence of 2 microM cimetidine, an H2-receptor antagonist, but not altered by 2 microM pyrilamine, an H1-receptor antagonist. Histamine-induced NO release was significantly reduced by the addition of 20 microM of the Rp diastereomer of adenosine cyclic 3',5'-phosphorothioate (Rp-cAMPS), a membrane-permeable antagonist of cyclic adenosine monophosphate (cAMP). Application of 100 microM forskolin, an activator of adenylate cyclase, induced NO release from porcine aortic endothelial cells. Fura-2 acetoxymethylester (fura-2/AM) studies showed that addition of 100 microM histamine did not produce any significant increase in the use of free concentration of intracellular Ca2+. These results suggest that in porcine aortic endothelial cells, NO-mediated vasodilation might be caused by production of cAMP initiated through the histamine H2-receptor.

Abstract
The mechanism causing cerebral vasodilatation during hypoxia remains unclear. A role for histamine is suspected because H2 receptor-blocking drugs blunt the hypoxia-induced increase in cerebral blood flow (CBF). Moreover, in vitro blockade of H1 receptors by chlorpheniramine decreases the vasodilatation of cerebral arteries that is induced by histamine. The present study tested the hypothesis that an H1 receptor blocker (d-chlorpheniramine) would have a similar effect in vivo during hypoxia. Isocapnic hypoxia (inspired oxygen fraction, FIO2 = 0.10; inspired carbon dioxide fraction, FICO2 = 0.035) was induced in 16 conscious dogs randomly divided into two groups: eight dogs received saline intravenously (controls) at time 0 (normoxia) and after 2 h and 4 h hypoxia, and the other eight dogs received d-chlorpheniramine intravenously (0.5 mg kg-1) to block the H1 receptors. Regional CBF was measured by the radioactive microspheres technique 15 min after each injection of d-chlorpheniramine or saline. In the control group, CBF increased during hypoxia in all regions of the brain. In the d-chlorpheniramine group, total CBF increased similarly after 2 h of hypoxia. After 4 h of hypoxia, the increase was limited, especially in the pons, cerebral peduncles, hippocampus, hypothalamus, thalamus, and occipital lobes (six out of 12 studied regions). It is concluded that the H1 blocker d-chlorpheniramine did not strongly inhibit the increase in CBF during hypoxia. After cumulative doses, however, as in the fourth hour of hypoxia, the increase in total CBF was limited.

Abstract
Previous studies suggest that nitric oxide (NO) is involved in headaches induced by i.v. infusion of the vasodilator and NO donor glyceryl trinitrate (GTN) in healthy subjects. Extending these studies to sufferers of migraine without aura, it was found that migraineurs experienced a stronger headache than non-migraineurs. In addition, most migraineurs experienced a delayed migraine attack at variable times (mean 5.5 h) after GTN provocation. This biphasic headache response in migraineurs may be linked to hypersensitivity in the NO-cGMP pathway. Thus, compared to controls, migraineurs were found to be more sensitive to GTN-induced intracranial arterial dilatation, which is known to be mediated via liberation of NO and subsequent synthesis of cGMP Furthermore, histamine infusions in migraineurs induced headache responses and intracranial arterial responses resembling those induced by GTN in migraineurs. Histamine is known to liberate NO from the endothelium via stimulation of the H1 receptor, which is present in the large intracranial arteries in man. Because both immediate histamine-induced headache and intracranial arterial dilatation and delayed histamine-induced migraine are blocked by H1-receptor blockade, a likely common pathway for GTN and histamine-induced headaches/migraines and intracranial arterial responses may be via activation of the NO-cGMP pathway. The delay in the development of these experimental migraines may reflect activation of multiple physiological processes. The intracranial arteries of migraineurs were found supersensitive to the vasodilating effect of GTN (exogenous NO). This relates to clinical findings suggesting dilatation of the large intracranial arteries on the headache side during spontaneous migraine attacks. The function of arterial regulatory mechanisms involving NO in migraine was therefore studied. In peripheral arteries, no endothelial dysfunction of NO was found and cardiovascular and intracranial arterial sympathetic function was normal. A mild parasympathetic dysfunction may be involved and may, via denervation supersensitivity, be responsible for the observed supersensitivity to NO. Another possibility is that NO initiates a perivascular neurogenic inflammation with liberation of vasoactive peptides. NO also mediates a variety of other physiological phenomena. One of these, the pain-modulating effect observed in animals, was evaluated in a human study using GTN infusion and measurements of pain thresholds. No definite effects of GTN were demonstrated. The precise mechanisms involved in NO-triggered migraines and which part of the NO-activated cascade that is involved remain to be determined. The possibilities for pharmacological stimulation and/or inhibition of several steps of the NO-activated cascade increase rapidly and soon may be available for human studies.

Abstract
Histamine exerts multiple biological actions through one of three receptor subtypes (H1, H2, and H3). This review focuses on new developments regarding the structure and function of the H2 receptor. In addition to the important role this receptor plays in stimulating gastric acid secretion, recent studies have demonstrated that it is also involved in regulating gastrointestinal motility and intestinal secretion. The potential role of the H2 receptor in regulating cell growth and differentiation has also been added to the list of actions this biogenic amine may exert in both normal and transformed tissues. Molecular cloning of the gene indicates that it has the structural characteristics of a heptahelical G protein-linked receptor. Site-directed mutagenesis studies of this receptor reveal the presence of key amino acids within the third and fifth transmembrane domains that are critical for ligand recognition. Molecular approaches have also shed light on the structural components of the H2 receptor important in regulating desensitization and internalization. Although the H2 receptor was classically thought to couple to the adenylate cyclase pathway, recent work with the cloned receptor indicates that it can also activate the phosphoinositide signaling cascade through an independent G protein-dependent mechanism. The novel observation that histamine may stimulate c-fos gene expression lends further support to the possible role of this receptor in regulating cell growth and differentiation.

Abstract
1. Histamine induces relaxation of human cranial arteries. Studies have revealed that the relaxant histamine H1-receptor predominates in human cerebral and the H2-receptor in temporal arteries, while H1- and H2-receptors are of equal importance in the middle meningeal artery. The purpose of the present study was to examine the role of the endothelium and nitric oxide in histamine-induced responses and to show the presence of mRNA encoding H1- and H2-receptors in human cranial arteries. 2. Electrophoresis of polymerase chain reaction (PCR) products from human cerebral, middle meningeal and temporal arteries, demonstrated products corresponding to mRNA encoding both H1- and H2-receptors in arteries with and without endothelium. The amplified PCR products were sequenced and showed 100% homology with the published sequences of these histamine receptors. 3. A sensitive in vitro system was used to study vasomotor responses to histamine. In precontracted cerebral, middle meningeal and temporal arteries with and without endothelium, histamine caused a concentration-dependent relaxation with Imax values between 87% and 81% and pIC50 values between 8.14 and 7.15. In arteries without endothelium the histamine-induced relaxation was significantly less potent (Imax values between 87% and 66% and pIC50 values between 7.01 and 6.67) than in cranial arteries with an intact endothelium. 4. This addition of histamine to arteries without endothelium and pretreated with the histamine H2-antagonist, cimetidine (10(-5) M), caused a concentration-dependent contraction of the cranial arteries with Emax values between 86% and 29% and pEC50 values between 7.53 and 6.77. This contraction was blocked by the histamine H1-receptor antagonist, mepyramine (10(-7) M), and even turned into a relaxation with Imax values between 84% and 14% and pIC50 values between 7.42 and 5.86. 5. The nitric oxide synthase inhibitor NG-nitro-L-arginine methyl ester (L-NAME, 3 x 10(-5) M) significantly inhibited the relaxant response to histamine in cerebral and temporal arteries (pIC50 values between 7.43 and 7.13). The combined treatment with L-NAME (3 x 10(-5) M) and cimetidine (10(-5) M) caused a further displacement of the concentration-response curve (pIC50 values between 7.14 and 6.57) and decreased the maximum relaxant responses in all three cranial arteries (Imax values between 62% and 39%). 6. In conclusion, this is the first study which show mRNA encoding histamine H1- and H2-receptors in human cranial arteries. The results indicate that histamine-induced relaxation of human cranial arteries is partially mediated via an endothelial H1-receptor coupled to the production of nitric oxide and partially via a H2-receptor associated with the smooth muscle cells. In addition, there is evidence for a contractile H1-receptor in the smooth muscle cells in these arteries.

Abstract
Histamine has been widely used experimentally to induce headache in healthy subjects and migraine in migraineurs. There is evidence that the vascular effects of histamine are at least partially mediated by nitric oxide (NO). Hence we hypothesized that subjective symptoms and hemodynamic effects of histamine could be reduced by systemic NO-synthase inhibition. We therefore studied the effect of pretreatment with N-monomethyl-L-arginine (L-NMMA), a competitive inhibitor of NO-synthase, or placebo on headache, flush and discomfort scores during histamine infusion. Additionally, blood flow velocities in the middle cerebral and the ophthalmic artery and ocular fundus pulsations were measured. Whereas L-NMMA blunted the effect of histamine in the ophthalmic artery and the ocular circulation, NO-synthase inhibition did not mitigate subjective symptoms. Histamine did not affect mean blood flow velocities in the middle cerebral artery. Hence, we conclude that NO-synthase inhibition reduces the histamine-induced vascular effects in the ocular circulation, but is not sufficient to attenuate or abort the subjective symptoms provoked by histamine infusion.

Abstract
The molecular mechanisms of migraine pain have not yet been clarified. Monoamine and the peptide neurotransmitters involved in neurogenic inflammation do not cause significant head pain. Our previous studies of glyceryl trinitrate (GTN) and histamine-induced headaches have suggested that nitric oxide (NO) is the causative molecule in migraine pain. We furthermore suggest that substances capable of inducing experimental vascular headache do so via a common mediator which is NO. Finally, it is suggested that drugs exert their antimigraine activity by inhibiting NO or subsequent steps in the cascade of intracellular reactions triggered by NO. These novel observations change current views on vascular headache mechanisms and the importance of NO as an initiator of the migraine attacks dictates new approaches to the pharmacological treatment of migraine and other vascular headaches.

Abstract
This study demonstrates the presence of histamine H1 and H2 receptors and purinoreceptors A1 and A2 on endothelial cells derived from human brain microvessels (HBEC). Histamine induced formation of both inositol triphosphate (IP3) (EC50 = 10.2 +/- 0.9 microM) and cyclic adenosine monophosphate (cAMP) (EC50 = 5.2 +/- 0.9 microM) in HBEC in a concentration-dependent fashion. IP3 formation was inhibited by H1 receptor antagonists mepyramine maleate and chlorphenyramine, but not by H2 receptor antagonist cimetidine. Production of cAMP was efficiently inhibited by cimetidine. Selective A1 receptor agonists decreased, whereas A2 receptor agonists increased cAMP production in HBEC. When added together with histamine to HBEC cultures, both A1 and A2 receptor agonists diminished histamine-induced IP3 stimulation. This effect was reversed in the presence of specific A1 and A2 receptor antagonists, respectively. Marked augmentation of histamine-induced cAMP production by HBEC was observed in the presence of A2 agonist. This response was dependent on H1 receptors, since it was reduced in the presence of H1-receptor antagonist. It is suggested that interaction between histamine and adenosine modulating induction of second messengers in HBEC may influence endothelium-dependent responses of brain microvascular compartments.

Abstract
1. The histamine receptors were characterized on isolated circular segments of trachea and pulmonary arteries from the guinea-pig. The motor responses to histamine H1-, H2- and H3-receptor agonists and antagonists were tested and the responses obtained were analysed in relation to the respiratory epithelium and the vascular endothelium. 2. Histamine induced a biphasic response in trachea and in pulmonary arteries. In low concentrations, histamine acted as a potent relaxant agent of precontracted segments and in moderate concentrations it constricted both precontracted and resting segments. When arterial segments from different parts of the pulmonary vascular tree were compared, only small interregional differences in the vasomotor response were seen. 3. Mepyramine caused a parallel shift to the right of the histamine-induced concentration-response curves for both the trachea and the pulmonary artery, indicating a contractile H1-receptor. Cimetidine did not affect the histamine-induced contraction of the trachea, but a shift to the left was evident for low concentrations of histamine in the pulmonary artery. This is consistent with a dilator H2-receptor in the pulmonary artery. The pA2-value for mepyramine in the pulmonary artery, 8.75, was not affected by the presence of cimetidine. Thioperamide, a selective H3 antagonist, shifted the concentration-response for the trachea to the left. Schild analysis for histamine and mepyramine yielded a line with a slope of 0.61, whereas the same analysis in the presence of thioperamide yielded a line with a slope of 1.05 and an approximated pA2-value of 9.57. These results indicate the presence of a relaxant H3 receptor in the trachea. In precontracted tracheal segments, application of mepyramine and cimetidine did not affect the low dose histamine relaxation. Thioperamide caused a parallel shift of the histamine concentration-response curve to the right, supporting the suggestion of a dilator H3-receptor in the trachea. The pA2-value for thioperamide, in the presence of mepyramine, was 7.79. In precontracted pulmonary arteries the histamine-induced dilatation was small. In the presence of mepyramine a rather strong histamine-induced dilatation became evident and this concentration-response curve could be shifted to the right by cimetidine, with a pA2-value of 6.49. This is compatible with a dilator H2-receptor. 4. The H1-receptor agonists, thiazolylethylamine, 2-methylhistamine and pyridylethylamine and the rather unselective H2-agonist, 4-methylhistamine, induced contraction of resting tracheal and pulmonary arterial segments. In precontracted segments of trachea, all H1 and H2 agonists studied induced a dilator response. The two rather unselective histamine receptor agonists 2-methylhistamine and 4-methylhistamine were about 100 times more potent than other H1 and H2 agonists tested. In the pulmonary artery, the H2 agonists, impromidine, dimaprit and 4-methylhistamine induced a concentration-dependent relaxation. The relaxation of the pulmonary artery, elicited by the H1 agonists,thiazolylethylamine and pyridylethylamine, was smaller, but more potent than the response induced by the H2 agonists. This may reflect the presence of a separate dilator H1-receptor.5. R-alpha-methylhistamine induced a three phased response in precontracted tracheal segments. In low concentrations, a concentration-dependent dilator response appeared. At moderate concentrations, a stage with a plateau or a small contraction was seen, followed at high concentrations by a new concentration-dependent relaxation. The first dilator phase was similar to that obtained for histamine in the same preparation.6. Removal of the epithelium or endothelium enhanced the contractile histamine response in both the trachea and the pulmonary artery as well as the dilator response in the trachea. These results support the hypothesis that the endothelial layer may serve as a barrier against the penetration of certain mediators. In the precontracted pulmonary artery, the small initial dilatation was abolished whereas the second dilatation seen in the presence of mepyramine was slightly reduced. This may reflect the influence of two separate histamine receptors, one of which is associated with the release of an endothelium dependent dilator factor or factors.7. In the guinea-pig trachea, histamine-induced contraction is mediated through H1-receptors where as dilatation probably involves an H3-receptor on the smooth muscle. The guinea-pig pulmonary artery appears to be endowed with a contractile H1 receptor on the smooth muscle cells and a dilator H1 receptor located on the endothelium. A dilator H2 receptor on the smooth muscle cells seems, at least in vitro, to be the most potent mediator of histamine-mediated pulmonary arterial dilatation.

Abstract
1. The histamine receptor sub-types that are involved in the initiation and maintenance of prostacyclin (PGI2) release from human endothelial cells have been investigated. 2. Endothelial cells cultured from umbilical vein (HUVEC) were incubated with either histamine, the selective H1-receptor agonists, 2-methyl histamine (2-MeHA) or thiazolylethylamine (ThEA), the H1-agonist/H3-antagonist, beta-histidine (beta-His), the selective H2-agonist, dimaprit, the H2-agonist/H3-antagonist, impromidine, the selective H3-agonist, (R)alpha-methylhistamine ((R)alpha-MeHA) and the H3-antagonist, thioperamide. 3. The H1-agonists and the H3-agonist (R)alpha-MeHA induced a concentration (100 nM-1 mM) and time-dependent release of PGI2 as determined by radioimmunoassay for 6-keto-PGF1 alpha, but were less potent than histamine itself. The rank order of potency was the same following 30 min and 24 h incubation, i.e. histamine > ThEA > 2-MeHA >> beta-His > (R)alpha-MeHA. 4. Histamine and 2-MeHA (1 microM-1 mM), ThHEA (10 microM-1 mM) and (R)alpha-MeHA (1 mM), but not beta-His, induced a significantly greater increase in PGI2 release after 24 h incubation than after 30 min incubation (P < 0.05). 5. Neither the selective H2-agonist, dimaprit, nor the H2-agonist/H3-antagonist, impromidine alone induced release of PGI2. 6. The H1-antagonist, mepyramine (10 microM), abolished release of PGI2 induced by histamine, the H1-agonists and (R)alpha-MeHA but the H2-antagonist cimetidine (10 microM) and the H2/H3-antagonist, burimamide (10 microM) did not significantly modulate PGI2 release. 7. Although the H3-agonist (R)alphax-MeHA induced release of PGI2, it failed to modulate PGI2 release in the presence of histamine.8. Low concentrations of the H3-antagonist, thioperamide (100 nM) did not modulate histamine release of PGI2 at all but after 24 h incubation, thioperamide (10-4 M) partially reduced PGI2 release in the presence of histamine.9. These results indicate that PGI2 from HUVEC is initiated and maintained via histamine HI-receptor occupancy. There appears to be no involvement of either H2- or H3-receptors in this particular endothelial cell histaminergic response.

Abstract
The possibility that endogenous histamine plays an important role in modulating the pathophysiology of heat stress was examined in young rats using a pharmacological approach. Subjection of young animals (six to seven weeks old) to heat stress at 38 degrees C for 4 h in a biological oxygen demand incubator (relative humidity 47-50%, wind velocity 20-25 cm/s) resulted in a profound increase in blood-brain barrier permeability to Evans Blue albumin (whole brain 375%) and [131I]sodium (whole brain 478%) along with a significant reduction in the cerebral blood flow (mean 34%). The water content of the whole brain was elevated by 4.5% (about 19% volume swelling) from the control. At this time-period, the plasma and whole brain 5-hydroxytryptamine levels were elevated by 656% and 328%, respectively, from the control group. Pretreatment with cimetidine (a histamine H2 receptor antagonist) significantly thwarted the increases in the brain water content and the blood-brain barrier permeability. In cimetidine-pretreated animals, the cerebral blood flow was significantly elevated and the plasma and brain 5-hydroxytryptamine (serotonin) levels were slightly but significantly reduced as compared with the untreated stressed group. However, prior treatment with mepyramine (a histamine H1 receptor antagonist) neither attenuated the changes in water content and the blood-brain barrier permeability nor altered the cerebral blood flow and 5-hydroxytryptamine levels. In fact, there was a significantly higher permeation of the tracers across the cerebral vessels in these drug-treated animals along with a greater accumulation of the brain water content as compared with the untreated stressed group. The cerebral blood flow and 5-hydroxytryptamine levels showed only minor changes from the untreated stressed group. These results show, probably for the first time, that (i) the endogenous histamine plays an important role in the pathophysiology of heat stress, and (ii) this effect appears to be mediated via specific histamine H2 receptors.

Abstract
1. Actions of histamine on the voltage-dependent Ba2+(Ca2+) currents (IBa, ICa) were investigated using the whole-cell patch-clamp technique on dispersed smooth muscle cells from the rabbit saphenous artery. 2. Histamine (half-maximal dose, EC50 = 530 nM) augmented the IBa evoked by a brief depolarizing pulse (100 ms duration; to +10 mV from a holding potential of -80 mV) in a concentration-dependent manner. The maximum augmentation was obtained with 30 microM-histamine (1.29 times control). This augmentation of IBa was inhibited by the H3-antagonist, thioperamide (Ki = 30 nM, slope of the Schild plot = 1.0), but not by H1- or H2-antagonists (mepyramine or diphenhydramine, or cimetidine, respectively). 3. An H3-agonist, R alpha-methylhistamine (EC50 = 93 nM), also augmented IBa in a concentration-dependent manner at a holding potential of -80 mV and the maximum augmentation (1.25 times control) was obtained with 10 microM. This augmentation was also inhibited by thioperamide, but not by the above H1- and H2- antagonists. 4. Intracellularly applied 500 microM-guanosine 5'-triphosphate (GTP) enhanced, but 1 mM-guanosine 5'-O-(2-thiodiphosphate) (GDP beta S) abolished, the histamine-induced augmentation of IBa. When one of the non-hydrolysable GTP analogues, guanosine 5'-O-(3-thiotriphosphate) (GTP gamma S; greater than 5 microM), guanylyl-imidodiphosphate (GMP-PNP; 200 microM) or guanylyl (beta, gamma-methylene)-diphosphonate (GMP-PCP; 1 mM) was intracellularly applied, the IBa amplitude evoked without the application of histamine was not affected, but the excitatory effect of histamine on IBa was reversed to an inhibition. Pre-treatment with pertussis toxin (PTX: 300 ng/ml and 3 micrograms/ml) did not modify the histamine-induced responses in the absence or presence of GTP gamma S. 5. 4 beta-Phorbol 12,13-dibutylate (PDBu) increased the amplitude of IBa. However, this action of PDBu was not enhanced by the application of GTP (500 microM) in the pipette, but additional application of histamine further increased the amplitude of IBa. Pre-treatment with a potent non-selective protein kinase inhibitor, 1-(5-isoquinolinesulphonyl)-2-methylpiperazine dihydrochloride (H-7; 100 microM), did not modify the histamine-induced current augmentation or inhibition observed in the presence or absence of intracellular GTP gamma S.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
1. The effects of histamine on isolated goat middle cerebral artery were examined using two experimental approaches: recording of isometric tension and measurement of [3H]-noradrenaline efflux. 2. Cumulative addition of histamine (10(-7)-3 x 10(-2)M) and 2-pyridylethylamine (2-PEA, 10(-6)-3 x 10(-2)M) produced concentration-dependent contractile responses. Preincubation with diphenhydramine (10(-7), 10(-6)M) or cimetidine (10(-7), 10(-6)M) competitively inhibited the histamine-induced contractile response. 3. Endothelium denudation enhanced the contractile effects of histamine. 4. Transmural electrical stimulation elicited contractions which were enhanced by histamine (10(-7)M), 2-PEA (10(-6)M) and dimaprit (10(-4)M). Diphenhydramine (10(-5)M) inhibited the action of histamine, but cimetidine did not. 5. Noradrenaline (10(-8)-10(-4)M) elicited concentration-dependent contractions which were unaffected by histamine (10(-7)M). 6. In arteries preloaded with [3H]-noradrenaline, transmural electrical stimulation induced an increase in the tritium efflux, which was enhanced in the presence of histamine (10(-7)M). 7. Therefore, histamine contracts cerebral arteries via specific non-endothelial H1-receptors, and enhances perivascular adrenergic neurotransmission through specific presynaptic H1-receptors by a mechanism involving increases in noradrenaline release.

Abstract
The subtypes of histamine receptors mediating dilatation of human meningeal arteries have been tested in vitro, using "selective" antagonists, and compared with cerebral and temporal arteries previously examined. Dilatory responses were tested after preconstriction with prostaglandin F2 alpha. Both mepyramine and cimetidine caused a parallel shift to the right of the histamine concentration-response curve, suggesting the presence of both H1- and H2-receptors. Combined treatment with mepyramine and cimetidine caused further displacement of the concentration-response curve to the right. Schild analysis indicated pA2 values of 6.3 for cimetidine and 9.8 for mepyramine in situations of near complete blockade of either of the receptors. Both H1- and H2-receptors seem of importance for the histamine-induced dilatation in meningeal arteries and neither appear to dominate. The data considered in conjunction with our previous findings support the finding that experimental histamine-induced headache due to vasodilatation is intracranial of origin.

Abstract
Agonists and antagonists of histamine were used to characterize the stimulation of inositol phosphates formation and elevation of intracellular Ca2+ by histamine in cultured non-pigmented epithelial (NPE) cells from human ciliary body. Agonists specific for the H1 histamine receptor subtype were 20- to 200-fold more potent than the H2-specific agonists tested, and 5-16% as potent as histamine in inositol phosphates stimulation. An H1 antagonist was 10,000-fold more potent than an H2 antagonist in blocking histamine stimulation of inositol phosphates. H1 agonists also mimicked and H1 antagonists inhibited the elevation of intracellular Ca2+ by histamine. The first phase of the Ca2+ response to histamine was largely independent of extracellular Ca2+ while the second phase required extracellular Ca2+. Dose-response curves for histamine elevation of intracellular Ca2+ (EC50 = 10 microM, maximum at 100 microM) and inositol phosphates (EC50 = 2 microM, maximum at 100 microM) were similar. These data support the characterization of the NPE histamine receptor as an H1 receptor linked to elevation of inositol phosphates and intracellular Ca2+.

Abstract
The subtype of histamine receptors in brain vessels of guinea-pig has been characterized by ligand binding and in-vitro pharmacology using selective antagonists. In the basilar artery histamine caused a concentration-related contraction with an EC50 of 1.6 +/- 0.3 microM. H1-receptor blockade with mepyramine and chlorpheniramine caused a displacement to the right of the histamine concentration-response curve with an apparent KD of 0.4 and 4.6 nM respectively, whereas H2-receptor blockade with cimetidine was without effect. Histamine did not induce any dilatory responses of vessels procontracted by 60 mM potassium-containing buffer in the presence or absence of histamine antagonists. Ligand-binding studies with [3H]mepyramine yielded a KD value of 5.5 nM in pial vessel membranes and 1.7 nM in the choroid plexus, confirming the presence of H1-receptors. Nimodipine caused a concentration-related blockade of histamine-induced contractions. Omission of Ca2+ from the extracellular medium for 30 min reduced the contractile responses to histamine in the basilar artery by 96%. Subsequent addition of Ca2+ caused concentration-related contractions which were inhibited by nimodipine. Thus, the histamine H1-receptor activation in guinea-pig basilar artery is coupled to dihydropyridine-sensitive Ca2+ channels.

Abstract
We used television microscopy and an image-splitting technique to monitor the changes in diameter produced by histamine applied locally to mouse pial arterioles in vivo. A high dose (50 micrograms/ml, 3 X 10(-4) M) of histamine constricted the arterioles, whereas lower doses (20 and 10 micrograms/ml) relaxed them. Constriction was blocked and dilation occurred when selective injury of the endothelium was produced by light from a helium-neon laser in the presence of intravascular Evans blue. From this we conclude that the constriction was endothelium-dependent and was caused by the release of an endothelium-derived constricting factor. Constriction was also blocked by each of two antagonists of the H1 histamine receptor and by pretreatment of the arterioles with indomethacin. H1 blockade unmasked a dilating action of 1 micrograms/ml histamine, a dose too low to affect the diameter of arterioles not treated with the H1 blocker. An H2 blocker interfered with the relaxation by low-dose (10 micrograms/ml, 6 X 10(-5) M) histamine. These data indicate that for mouse pial arterioles, histamine can interact with H1 receptors on the endothelium to release an endothelium-derived constricting factor that causes constriction of the underlying muscle while simultaneously interacting with H2 receptors in the muscle that mediate relaxation of the vessel.

Abstract
1. The subtypes of histamine-receptors which mediate dilatation of small human temporal arteries have been characterized in vitro using 'selective' agonists and antagonists. 2. Dilatory responses were studied after preconstriction with prostaglandin F2 alpha since contraction was not seen at histamine concentrations up to 10(-4) M. Histamine caused a concentration-related relaxation of cerebral vessels with an IC50 value of 2.8 +/- 0.6 X 10(-7) M. 3. Cimetidine caused a parallel shift to the right of the histamine concentration-response curve whereas mepyramine was without observable effect. This suggests the presence of histamine H2-receptors only. However, combined treatment with mepyramine and cimetidine caused a more marked displacement of the concentration-response curve to the right. Schild analysis indicated that in situations of near complete blockade of the histamine H1-receptor subtypes, simple competitive antagonism at H2-receptors can be revealed with a pA2 value of 6.58 for cimetidine. The apparent pA2 value for mepyramine was 8.58. 4. The 'selective' H1-receptor agonists pyridylethylamine, 2-methylhistamine and thiazolylethylamine, and the H2-receptor agonists dimaprit, impromidine and 4-methylhistamine all mimicked the histamine response, but all except impromidine were less potent than histamine. The order of potency was impromidine greater than thiazolylamine greater than 4-Me-histamine greater than 2-Me-histamine greater than dimaprit greater than pyridylethylamine greater than tele-Me-histamine. 5. These results indicate that the histamine-induced dilatation in small human temporal arteries is mediated by both H1- and H2-receptors and that the latter subtype of histamine receptors predominates.
