[3H]-Mesulergine labels 5-HT7 sites in rat brain and guinea-pig ileum but not rat jejunum. (1/38)

1. The primary aim of this investigation was to determine whether binding sites corresponding to the 5-HT7 receptor could be detected in smooth muscle of the rat jejunum. Binding studies in rat brain (whole brain minus cerebellum) and guinea-pig ileal longitudinal muscle were also undertaken in order to compare the binding characteristics of these tissues. Studies were performed using [3H]-mesulergine, as it has a high affinity for 5-HT7 receptors. 2. In the rat brain and guinea-pig ileum, pKD values for [3H]-mesulergine of 8.0 +/- 0.04 and 7.9 +/- 0.11 (n = 3) and Bmax values of 9.9 +/- 0.3 and 21.5 +/- 4.9 fmol mg(-1) protein were obtained respectively, but no binding was detected in the rat jejunum. [3H]-mesulergine binding in the rat brain and guinea-pig ileum was displaced with the agonists 5-carboxamidotryptamine (5-CT) > 5-hydroxytryptamine (5-HT) > or = 5-methoxytryptamine (5-MeOT) > sumatriptan and the antagonists risperidone > or = LSD > or = metergoline > ritanserin > > pindolol. 3. Despite the lack of [3H]-mesulergine binding in the rat jejunum, functional studies undertaken revealed a biphasic contractile response to 5-HT which was partly blocked by ondansetron (1 microM). The residual response was present in over 50% of tissues studied and was found to be inhibited by risperidone > LSD > metergoline > mesulergine = ritanserin > pindolol, but was unaffected by RS 102221 (3 microM), cinanserin (30 nM), yohimbine (0.1 microM) and GR 113808 (1 microM). In addition, the agonist order of potency was 5-CT > 5-HT > 5-MeOT > sumatriptan. 4. In conclusion, binding studies performed with [3H]-mesulergine were able to detect 5-HT7 sites in rat brain and guinea-pig ileum, but not in rat jejunum, where a functional 5-HT7-like receptor was present.  (+info)

Discriminative stimulus properties of indorenate, a serotonin agonist. (2/38)

OBJECTIVE: To determine whether indorenate, a serotonin-receptor agonist, can exert discriminative control over operant responses, to establish the temporal course of discriminative control and to compare its stimulus properties to a (5-HT)IA receptor agonist. [3H]-8-hydroxy-2-(di-N-propylamino) tetralin (8-OH-DPAT). DESIGN: Prospective animal study. ANIMALS: Ten male Wistar rats. INTERVENTIONS: Rats were trained to press either of 2 levers for sucrose solution according to a fixed ratio schedule, which was gradually increased. Rats were given injections of either indorenate or saline solution during discrimination training. Once they had achieved an 83% accuracy rate, rats underwent generalization tests after having received a different dose of indorenate, the training dose of indorenate at various intervals before the test, various doses of 8-OH-DPT, or NAN-190 administered before indorenate or 8-OH-DPAT. OUTCOME MEASURES: Distribution of responses between the 2 levers before the first reinforcer of the session, response rate for all the responses in the session, and a discrimination index that expressed the drug-appropriate responses as a proportion of the total responses. RESULTS: Indorenate administration resulted in discriminative control over operant responses, maintained at fixed ratio 10, at a dose of 10.0 mg/kg (but not 3.0 mg/kg). When the interval between the administration of indorenate and the start of the session was varied, the time course of its cue properties followed that of its described effects on 5-HT turnover. In generalization tests, the discrimination index was a function of the dose of indorenate employed; moreover, administration of 8-OH-DPAT (from 0.1 to 1.0 mg/kg) fully mimicked the stimulus properties of indorenate in a dose-dependent way. The (5-HT)IA antagonist NAN-190 prevented the stimulus generalization from indorenate to 8-OH-DPAT. Also, NAN-190 antagonized the stimulus control of indorenate when administered 45 minutes before the session, but not when administered 105 minutes before the session (i.e., 15 minutes before the administration of indorenate). CONCLUSION: (5-HT)IA receptors are of relevance to the stimulus function of indorenate. However, other receptor subtypes may also be involved. Hence, other agonists and specific antagonists should be studied before definite conclusions are drawn.  (+info)

Pharmacological characterization of 5-HT4 receptors mediating relaxation of canine isolated rectum circular smooth muscle. (3/38)

This study aimed to characterize for the first time in vitro 5-HT4 receptors in the canine gastrointestinal tract. For this purpose, we used circular muscle strips of the canine isolated rectum. In the presence of methysergide (60 microM), 5-HT induced relaxation of methacholine (1 microM)-precontracted muscle strips, yielding a monophasic sigmoidal concentration-relaxation curve (pEC50 7.2+/-0.07). Tetrodotoxin (0.3 microM) did not affect the curve to 5-HT, suggesting the inhibitory 5-HT receptor is located on the smooth muscle. Granisetron (0.3 microM) did also not affect the curve to 5-HT, which excludes the 5-HT3 receptor mediating the relaxation to 5-HT. The presence of methysergide rules out the involvement of 5-HT1, 5-HT2 or 5-HT7 receptors. 5-HT, the selective 5-HT4 receptor agonists R076186, prucalopride (R093877) and SDZ HTF-919 and the 5-HT4 receptor agonists cisapride and 5-MeOT relaxed the muscle strips with a rank order of potency R076186 = 5-HT > cisapride > prucalopride > or = SDZ HTF-919 > 5-MeOT. The selective 5-HT4 receptor antagonists GR 125487, RS 39604 and GR 113808 competitively antagonized the relaxations to 5-HT, yielding pK(B) estimates of 9.7, 7.9 and 9.1, respectively. The selective 5-HT4 receptor antagonist SB 204070 shifted the curve to 5-HT rightward and depressed the maximal response (apparent pA2 10.6). GR 113808 (10 nM) produced a parallel rightward shift of the curve to the selective 5-HT4 receptor agonists R076186 (pA2 8.8). It is concluded that 5-HT induces relaxation of the canine rectum circular muscle through stimulation of a single population of smooth muscle 5-HT4 receptors. For the first time, a nonhuman species was shown to exhibit relaxant 5-HT4 receptors in the large intestine.  (+info)

5-HT(4) receptors in nucleus tractus solitarii attenuate cardiopulmonary reflex in anesthetized rats. (4/38)

We determined whether the cAMP-protein kinase A (PKA) pathway modulation of the cardiopulmonary reflex was caused by activation of 5-HT(4) receptors at the level of the nucleus tractus solitarii (NTS) of the anesthetized rat. NTS microinjection of 5-methoxytryptamine (5-MeOT, 2.25 pmol, n = 13), a 5-HT-receptor agonist, attenuated the cardiopulmonary reflex-evoked bradycardia and tachypnea. Microinjection of RS-39604 (4.5 pmol, n = 6), a selective 5-HT(4)-receptor antagonist, blocked the attenuating effect of 5-MeOT. NTS microinjection of 8-bromoadenosine 3', 5'-cyclic monophosphate (8-BrcAMP, 9 nmol, 45 nl, n = 10), a membrane-permeant analog of cAMP, significantly attenuated the reflex bradycardia and tachypnea. Rp-adenosine 3',5'-cyclic monophosphorothioate (4.5 nmol, n = 6), a cAMP-dependent PKA inhibitor, had no effect on the cardiopulmonary reflex when microinjected into the NTS alone but when given before a microinjection of either 8-BrcAMP (n = 6) or 5-MeOT (n = 6) blocked the attenuating effect on the reflex-evoked bradycardia. Thus stimulation of 5-HT(4) receptors within the NTS depresses the reflex bradycardia components of the cardiopulmonary reflex via a cAMP-dependent PKA pathway.  (+info)

Smooth muscle layer-dependent distribution of 5-hydroxytryptamine(7) receptor in the porcine myometrium. (5/38)

1. To analyse the mechanisms of muscle layer-dependent inhibition of porcine myometrial contractility by 5-hydroxytryptamine (5-HT), the effects of 5-HT, 5-carboxamidotryptamine(5-CT), 5-methoxytryptamine (5-MeOT), forskolin and cyclic adenosine 3', 5'-monophosphate (cyclic AMP) analogues on spontaneous and stimulant-induced contractions were examined in longitudinal (LM) and circular muscles (CM). In addition, accumulation of cyclic AMP by 5-HT and distribution of 5-HT(7) receptors in LM and CM layers were compared using biochemical and molecular approaches. 2. 5-HT receptor agonists inhibited the spontaneous contractions of LM and CM (5-CT>5-HT>5-MeOT), but CM was more sensitive than was LM. The inhibition by the agonists was antagonized by methiothepin (100 nM). 3. Carbachol-, high-K(+)-, histamine- and Ca(2+)-induced contractions were inhibited by 5-HT with different responses (CM>LM). Even in the presence of 3-isobutyl-1-methylxanthine (IBMX), the inhibition by 5-HT in the CM was still more conspicuous than that in the LM. 4. Compared with the CM, the inhibition of spontaneous contraction by forskolin, dibutyryl-cyclic AMP and 8-bromo-cyclic AMP was marked in the LM. 5. 5-HT (1 nM - 1 microM) increased the cyclic AMP in both muscle layers, but the increment in the CM was higher than that in the LM whether IBMX was present or not. 6. LM and CM layers contained a single class of [(3)H]-5-CT binding sites with a similar K(d) value (0.21 - 0.24 nM). However, B(max) (5-HT(7) receptor concentration) in the CM (120.6 fmol mg(-1) protein) was higher than that in the LM (30.4 fmol mg(-1) protein). 7. The molecular study (reverse transcription polymerase chain reaction) demonstrated the expression of 5-HT(7) receptor mRNA in the CM was higher than that in the LM. 8. These results suggest that the muscle layer-dependent difference in inhibition by 5-HT is not restricted to spontaneous contraction but applies to various contractions in the porcine myometrium. Different inhibition of the contractility by 5-HT is caused by muscle layer-related accumulation of cyclic AMP (CM>LM), due to smooth muscle-layer dependent distribution (CM>LM) of 5-HT(7) receptors.  (+info)

Serotonin and pancreatic duct function. (6/38)

1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct cells appears to mediate the inhibitory effect of 5-HT. 4. [Ca2+]i is unlikely to mediate the inhibitory effect of 5-HT.  (+info)

Modulation by serotonin 5-HT(4) receptors of long-term potentiation and depotentiation in the dentate gyrus of freely moving rats. (7/38)

Tetanization-induced long-term potentiation (LTP) in the hippocampus can be depotentiated by low-frequency stimulation. 5-HT(4) receptors are expressed in the hippocampus and are suggested to be involved in hippocampus-dependent cognitive processes. Since the role of these receptors in the dentate gyrus has yet not been characterized, this study investigated the effects of 5-HT(4) receptors on basal synaptic transmission, LTP and depotentiation in the dentate gyrus of freely moving rats. Male Wistar rats were chronically implanted with a recording electrode in the dentate gyrus granule cell layer, a stimulation electrode in the medial perforant path and a cannula for drug administration in the ipsilateral ventricle. The 5-HT(4) agonist methoxytryptamine dose-dependently inhibited basal synaptic transmission and LTP. Priming of receptors by a dose of this agonist which elicited no significant change of basal synaptic transmission inhibited depotentiation. These effects could be prevented by the 5-HT(4) antagonist RS 39604, which did not produce independent effects on synaptic transmission, LTP or depotentiation. The effects of methoxytryptamine were confirmed with the highly selective 5-HT(4) agonist, RS 67333. These results strongly support a role for 5-HT(4) receptors in hippocampal synaptic plasticity and provide an important link to findings with regard to the involvement of 5-HT in processes related to learning and memory.  (+info)

Activity-dependent bidirectional regulation of GABA(A) receptor channels by the 5-HT(4) receptor-mediated signalling in rat prefrontal cortical pyramidal neurons. (8/38)

Emerging evidence has implicated a potential role for 5-HT(4) receptors in cognition and anxiolysis. One of the main target structures of 5-HT(4) receptors on 'cognitive and emotional' pathways is the prefrontal cortex (PFC). As GABAergic signalling plays a key role in regulating PFC functions, we examined the effect of 5-HT(4) receptors on GABA(A) receptor channels in PFC pyramidal neurons. Application of 5-HT(4) receptor agonists produced either an enhancement or a reduction of GABA-evoked currents in PFC neurons, which are both mediated by anchored protein kinase A (PKA). Although PKA phosphorylation of GABA(A) receptor beta3 or beta1 subunits leads to current enhancement or reduction respectively in heterologous expression systems, we found that beta3 and beta1 subunits are co-expressed in PFC pyramidal neurons. Interestingly, altering PKA activation levels can change the direction of the dual effect, switching enhancement to reduction and vice versa. In addition, increased neuronal activity in PFC slices elevated the PKA activation level, changing the enhancing effect of 5-HT(4) receptors on the amplitude of GABAergic inhibitory postsynaptic currents (IPSCs) to a reduction. These results suggest that 5-HT(4) receptors can modulate GABAergic signalling bidirectionally, depending on the basal PKA activation levels that are determined by neuronal activity. This modulation provides a unique and flexible mechanism for 5-HT(4) receptors to dynamically regulate synaptic transmission and neuronal excitability in the PFC network.  (+info)

5-Methoxytryptamine is a psychedelic tryptamine that is found in some plants and animals, as well as being produced synthetically. It is structurally similar to the neurotransmitter serotonin and is known for its ability to alter perception, thought, and mood. 5-Methoxytryptamine is also referred to as "mexamine" or "O-methylated tryptamine." It is a Schedule I controlled substance in the United States, making it illegal to possess or distribute without a license from the Drug Enforcement Administration (DEA).

In the medical field, 5-Methoxytryptamine does not have a specific use as a medication. However, it has been used in some research settings to study its effects on the brain and behavior. It is important to note that the use of 5-Methoxytryptamine or any other psychedelic substance should only be done under the supervision of trained medical professionals in a controlled setting due to the potential risks associated with their use.

Serotonin receptors are a type of cell surface receptor that bind to the neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). They are widely distributed throughout the body, including the central and peripheral nervous systems, where they play important roles in regulating various physiological processes such as mood, appetite, sleep, memory, learning, and cognition.

There are seven different classes of serotonin receptors (5-HT1 to 5-HT7), each with multiple subtypes, that exhibit distinct pharmacological properties and signaling mechanisms. These receptors are G protein-coupled receptors (GPCRs) or ligand-gated ion channels, which activate intracellular signaling pathways upon serotonin binding.

Serotonin receptors have been implicated in various neurological and psychiatric disorders, including depression, anxiety, schizophrenia, and migraine. Therefore, selective serotonin receptor agonists or antagonists are used as therapeutic agents for the treatment of these conditions.

Serotonin antagonists are a class of drugs that block the action of serotonin, a neurotransmitter, at specific receptor sites in the brain and elsewhere in the body. They work by binding to the serotonin receptors without activating them, thereby preventing the natural serotonin from binding and transmitting signals.

Serotonin antagonists are used in the treatment of various conditions such as psychiatric disorders, migraines, and nausea and vomiting associated with cancer chemotherapy. They can have varying degrees of affinity for different types of serotonin receptors (e.g., 5-HT2A, 5-HT3, etc.), which contributes to their specific therapeutic effects and side effect profiles.

Examples of serotonin antagonists include ondansetron (used to treat nausea and vomiting), risperidone and olanzapine (used to treat psychiatric disorders), and methysergide (used to prevent migraines). It's important to note that these medications should be used under the supervision of a healthcare provider, as they can have potential risks and interactions with other drugs.

Serotonin receptor agonists are a class of medications that bind to and activate serotonin receptors in the body, mimicking the effects of the neurotransmitter serotonin. These drugs can have various effects depending on which specific serotonin receptors they act upon. Some serotonin receptor agonists are used to treat conditions such as migraines, cluster headaches, and Parkinson's disease, while others may be used to stimulate appetite or reduce anxiety. It is important to note that some serotonin receptor agonists can have serious side effects, particularly when taken in combination with other medications that affect serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs) or monoamine oxidase inhibitors (MAOIs). This can lead to a condition called serotonin syndrome, which is characterized by symptoms such as agitation, confusion, rapid heart rate, high blood pressure, and muscle stiffness.

Tryptamines are a class of organic compounds that contain a tryptamine skeleton, which is a combination of an indole ring and a ethylamine side chain. They are commonly found in nature and can be synthesized in the lab. Some tryptamines have psychedelic properties and are used as recreational drugs, such as dimethyltryptamine (DMT) and psilocybin. Others have important roles in the human body, such as serotonin, which is a neurotransmitter that regulates mood, appetite, and sleep. Tryptamines can also be found in some plants and animals, including certain species of mushrooms, toads, and catnip.

Serotonin, also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter that is found primarily in the gastrointestinal (GI) tract, blood platelets, and the central nervous system (CNS) of humans and other animals. It is produced by the conversion of the amino acid tryptophan to 5-hydroxytryptophan (5-HTP), and then to serotonin.

In the CNS, serotonin plays a role in regulating mood, appetite, sleep, memory, learning, and behavior, among other functions. It also acts as a vasoconstrictor, helping to regulate blood flow and blood pressure. In the GI tract, it is involved in peristalsis, the contraction and relaxation of muscles that moves food through the digestive system.

Serotonin is synthesized and stored in serotonergic neurons, which are nerve cells that use serotonin as their primary neurotransmitter. These neurons are found throughout the brain and spinal cord, and they communicate with other neurons by releasing serotonin into the synapse, the small gap between two neurons.

Abnormal levels of serotonin have been linked to a variety of disorders, including depression, anxiety, schizophrenia, and migraines. Medications that affect serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs), are commonly used to treat these conditions.

Melatonin is a hormone that is produced by the pineal gland in the brain. It helps regulate sleep-wake cycles and is often referred to as the "hormone of darkness" because its production is stimulated by darkness and inhibited by light. Melatonin plays a key role in synchronizing the circadian rhythm, the body's internal clock that regulates various biological processes over a 24-hour period.

Melatonin is primarily released at night, and its levels in the blood can rise and fall in response to changes in light and darkness in an individual's environment. Supplementing with melatonin has been found to be helpful in treating sleep disorders such as insomnia, jet lag, and delayed sleep phase syndrome. It may also have other benefits, including antioxidant properties and potential uses in the treatment of certain neurological conditions.

It is important to note that while melatonin supplements are available over-the-counter in many countries, they should still be used under the guidance of a healthcare professional, as their use can have potential side effects and interactions with other medications.

'Receptors, Serotonin, 5-HT4' refer to a specific type of serotonin receptor found in various parts of the body, including the central and peripheral nervous systems. These receptors are activated by the neurotransmitter serotonin (5-hydroxytryptamine or 5-HT) and play an essential role in regulating several physiological functions, such as gastrointestinal motility, cognition, mood, and memory.

The 5-HT4 receptor is a G protein-coupled receptor (GPCR), which means it consists of seven transmembrane domains that span the cell membrane. When serotonin binds to the 5-HT4 receptor, it activates a signaling cascade within the cell, leading to various downstream effects.

The 5-HT4 receptor has been a target for drug development, particularly in treating gastrointestinal disorders such as constipation and irritable bowel syndrome (IBS). Additionally, some evidence suggests that 5-HT4 receptors may play a role in the treatment of depression, anxiety, and cognitive impairment. However, further research is needed to fully understand the therapeutic potential of targeting this receptor.

Melatonin receptors are a type of G protein-coupled receptor (GPCR) that bind to the hormone melatonin in animals. These receptors play a crucial role in regulating various physiological functions, including sleep-wake cycles, circadian rhythms, and seasonal reproduction.

There are two main types of melatonin receptors: MT1 (also known as Mel1a) and MT2 (Mel1b). Both receptor subtypes are widely expressed in the central nervous system, retina, and peripheral tissues. The activation of these receptors by melatonin leads to a range of downstream signaling events that ultimately result in changes in gene expression, cellular responses, and physiological processes.

MT1 receptors are involved in regulating sleep onset and promoting non-rapid eye movement (NREM) sleep. They have also been implicated in the regulation of mood, anxiety, and cognitive function. MT2 receptors play a role in regulating circadian rhythms and the timing of sleep-wake cycles. They are also involved in the regulation of pupillary light reflex, body temperature, and blood pressure.

Dysregulation of melatonin receptor signaling has been implicated in various sleep disorders, mood disorders, and neurodegenerative diseases. Therefore, understanding the function and regulation of melatonin receptors is an important area of research for developing novel therapeutic strategies for these conditions.

Ketanserin is a medication that belongs to a class of drugs called serotonin antagonists. It works by blocking the action of serotonin, a neurotransmitter in the brain, on certain types of receptors. Ketanserin is primarily used for its blood pressure-lowering effects and is also sometimes used off-label to treat anxiety disorders and alcohol withdrawal syndrome.

It's important to note that ketanserin is not approved by the FDA for use in the United States, but it may be available in other countries as a prescription medication. As with any medication, ketanserin should only be used under the supervision of a healthcare provider and should be taken exactly as prescribed.

Indole is not strictly a medical term, but it is a chemical compound that can be found in the human body and has relevance to medical and biological research. Indoles are organic compounds that contain a bicyclic structure consisting of a six-membered benzene ring fused to a five-membered pyrrole ring.

In the context of medicine, indoles are particularly relevant due to their presence in certain hormones and other biologically active molecules. For example, the neurotransmitter serotonin contains an indole ring, as does the hormone melatonin. Indoles can also be found in various plant-based foods, such as cruciferous vegetables (e.g., broccoli, kale), and have been studied for their potential health benefits.

Some indoles, like indole-3-carbinol and diindolylmethane, are found in these vegetables and can have anti-cancer properties by modulating estrogen metabolism, reducing inflammation, and promoting cell death (apoptosis) in cancer cells. However, it is essential to note that further research is needed to fully understand the potential health benefits and risks associated with indoles.

Muscle contraction is the physiological process in which muscle fibers shorten and generate force, leading to movement or stability of a body part. This process involves the sliding filament theory where thick and thin filaments within the sarcomeres (the functional units of muscles) slide past each other, facilitated by the interaction between myosin heads and actin filaments. The energy required for this action is provided by the hydrolysis of adenosine triphosphate (ATP). Muscle contractions can be voluntary or involuntary, and they play a crucial role in various bodily functions such as locomotion, circulation, respiration, and posture maintenance.

A dose-response relationship in the context of drugs refers to the changes in the effects or symptoms that occur as the dose of a drug is increased or decreased. Generally, as the dose of a drug is increased, the severity or intensity of its effects also increases. Conversely, as the dose is decreased, the effects of the drug become less severe or may disappear altogether.

The dose-response relationship is an important concept in pharmacology and toxicology because it helps to establish the safe and effective dosage range for a drug. By understanding how changes in the dose of a drug affect its therapeutic and adverse effects, healthcare providers can optimize treatment plans for their patients while minimizing the risk of harm.

The dose-response relationship is typically depicted as a curve that shows the relationship between the dose of a drug and its effect. The shape of the curve may vary depending on the drug and the specific effect being measured. Some drugs may have a steep dose-response curve, meaning that small changes in the dose can result in large differences in the effect. Other drugs may have a more gradual dose-response curve, where larger changes in the dose are needed to produce significant effects.

In addition to helping establish safe and effective dosages, the dose-response relationship is also used to evaluate the potential therapeutic benefits and risks of new drugs during clinical trials. By systematically testing different doses of a drug in controlled studies, researchers can identify the optimal dosage range for the drug and assess its safety and efficacy.

I must clarify that the term "Guinea Pigs" is not typically used in medical definitions. However, in colloquial or informal language, it may refer to people who are used as the first to try out a new medical treatment or drug. This is known as being a "test subject" or "in a clinical trial."

In the field of scientific research, particularly in studies involving animals, guinea pigs are small rodents that are often used as experimental subjects due to their size, cost-effectiveness, and ease of handling. They are not actually pigs from Guinea, despite their name's origins being unclear. However, they do not exactly fit the description of being used in human medical experiments.
