We describe a new class of drugs that selectively block serotonin M-receptors on peripheral neurones.
Our results show that serotonin functions as an extrasynaptic signal that independently activates multiple receptors at a distance from its release sites and identify at least six additional proteins that appear to act with serotonin receptors to mediate serotonin response.
Based on this multiplicity of effects and target tissues, it is not surprising that different types of receptors can selectively mediate effects of serotonin.
It is suggested that methiothepin-sensitive serotonin receptors are involved in the postsynaptic mechanism of behavioral sensitization.
We conclude that serotonin 5-HT2 receptors both induce and undergo several forms of desensitization.
Selective compounds for particular subtypes of serotonin receptors may yield selective pharmacologic effects.
Ultimately, we propose that novel antidepressant drugs that selectively target these serotonin receptors could be developed to yield improvements over current treatments for major depressive disorders.
BACKGROUND Serotonin receptors may play an important role in the pathophysiology of affective disorders.
This effect of serotonin is mediated via serotonergic receptors.
In view of the multiple roles played by the serotonergic systems in the central and peripheral nervous systems, these results are relevant to future studies of serotonin and its binding to its receptors.

How long do serotonin receptors take to heal?5 answersSerotonin receptors can exhibit varying recovery times based on the specific conditions and age. Studies have shown that the recovery of 5-HT2 receptors in the frontal cortex of rats can differ between mature and senescent individuals, with senescent rats displaying a slower recovery process. Additionally, the healing process of serotonin neurons in rats treated with MDMA indicated a significant reduction in neuronal markers initially, followed by a gradual recovery over time, with some animals showing enduring deficits even after a year. Furthermore, the effects of S(2)-receptor blockers on collagen-induced injuries in tendons demonstrated a significant impact on collagen turnover and scar tissue organization during the early stages of healing. These findings collectively suggest that the healing duration of serotonin receptors can vary depending on the specific circumstances and age-related factors.
What are the different types of drugs that act on serotonin receptors?4 answersThere are several types of drugs that act on serotonin receptors. Conventional serotonin-enhancing antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and serotonin and norepinephrine reuptake inhibitors (SNRIs), increase synaptic neurotransmission of serotonin through stimulation and blockade of various subtypes of 5-HT receptors. Serotoninergic hallucinogens, such as lysergic acid diethylamide (LSD), dimethyltryptamine (DMT), and psilocybin, agonistically act on 5-HT2A receptors, leading to increased glutamatergic transmission and neuroplasticity. Additionally, there are selective ligands and drugs that target specific 5-HT receptor subtypes, such as lorcaserin and pimavanserin, which target the 5-HT2C and 5-HT2A receptors, respectively, and provide new treatments for obesity and Parkinson's disease psychosis. Serotonin receptor ligands, including aripiprazole, ziprasidone, risperidone, olanzapine, mianserin, and quetiapine, are used for the treatment of central nervous system-related disorders. These drugs and ligands interact with different serotonin receptor subtypes to modulate serotonin neurotransmission and have therapeutic effects on various neuropsychiatric disorders.
Describe drugs that act on serotonin receptors including examples ?5 answersDrugs that act on serotonin receptors include atypical antipsychotic drugs (APDs) such as clozapine, aripiprazole, asenapine, iloperidone, lurasidone, olanzapine, quetiapine, risperidone, and ziprasidone. These drugs produce extensive blockade of serotonin (5-HT)(2A) receptors and may also stimulate 5-HT(1A) receptors. Some atypical APDs are also effective 5-HT(2C) receptor inverse agonists or neutral antagonists, 5-HT(6) or 5-HT(7) receptor antagonists. In addition to atypical APDs, there are other drugs that modulate serotonin receptors. For example, there are modulators of serotonin receptors that are being investigated for the treatment of various diseases and conditions such as metabolic diseases, central nervous system diseases, cephalic pain, migraine, and gastrointestinal disorders. Serotonin is one of the most important neurotransmitters in the central nervous system and is associated with the pathophysiology of many diseases including anxiety, schizophrenia, depression, and eating disorders.

Whant is the function of aquaporins?
5 answers
Aquaporins (AQPs) primarily facilitate water transport across cell membranes. However, their functions extend beyond water transport. AQPs are involved in transporting various small molecules like glycerol, urea, gases (CO2, NO, etc.), ions, and even silicon and arsenite. Additionally, AQPs play roles in unexpected functions such as tumor angiogenesis regulation, cell migration promotion, skin hydration regulation, neural signal transduction, cell proliferation, inflammation modulation, and organelle physiology. In the central nervous system, AQPs mediate water flux and are crucial in brain disorders like cerebral edema and neurodegenerative disorders. In the lungs, AQPs (AQP1, AQP2, AQP4, AQP5) are essential for fluid balance in respiratory processes. Overall, AQPs are vital in various physiological processes beyond simple water transport.
Is there an association between lowered serotonin concentrations or activity and depression?
5 answers
There is no consistent evidence linking lowered serotonin concentrations or activity to depression, as suggested by various studies. The serotonin hypothesis of depression, which posits a direct association between serotonin levels and depressive symptoms, has been extensively scrutinized. Research indicates that depression may not be caused by decreased serotonin activity, with some studies even suggesting that long-term antidepressant use could reduce serotonin concentration. Additionally, investigations into the effects of specific genetic variations related to the serotonergic and endocannabinoid systems have shown potential susceptibility to depression in carriers of certain alleles. Overall, the current body of evidence does not strongly support the notion that lowered serotonin concentrations or activity are directly linked to the development of depression.
How does ivermectin stimulate nerve regeneration?
5 answers
Ivermectin stimulates nerve regeneration through various mechanisms. Studies have shown that ivermectin promotes peripheral nerve repair by inducing fibroblasts to adopt a glia-like phenotype, leading to enhanced proliferation and migration of neural stem cells. Additionally, isoquercitrin, a compound with anti-oxidative properties, has been found to promote nerve regeneration and remyelination, increase the expression of nerve regeneration markers, and inhibit oxidative stress, ultimately aiding in motor functional recovery after peripheral nerve injury. Furthermore, experiments with planaria species revealed that exposure to ivermectin during regeneration resulted in patterning abnormalities and delayed regeneration, highlighting the impact of ion channel drugs like ivermectin on regenerative processes. These findings collectively demonstrate the multifaceted role of ivermectin in stimulating nerve regeneration through various cellular and molecular pathways.
How CBD is absorbed in the gut?
5 answers
Cannabidiol (CBD) absorption in the gut is influenced by several factors, including the presence of food, the formulation of CBD, and the activity of the endocannabinoid system. Studies have shown that the bioaccessibility of CBD significantly increases when consumed with food, particularly high-fat meals, which enhance its micellarization efficiency and, consequently, its absorption through the gut wall. This is attributed to the lipase enzyme activity and the presence of bile salts, which facilitate the formation of micelles from hydrolyzed lipids, aiding in the bioaccessibility of hydrophobic molecules like CBD. Furthermore, the development of novel nanoemulsion preparations of CBD has been shown to improve its poor solubility and absorption, demonstrating a significant increase in the area under the curve (AUC) and maximum concentration (Cmax) in pharmacokinetic profiles compared to conventional CBD oil formulations. This suggests that nanoemulsion formulations can enhance CBD absorption regardless of bile secretion, which is essential for the micelle formation required for the absorption of conventional CBD oil. The endocannabinoid system also plays a crucial role in the absorption and bioavailability of CBD. Activation of cannabinoid receptors in the gut can influence gastrointestinal motility and secretion, potentially affecting the absorption of CBD. Moreover, the modulation of this system can impact the permeability of the intestinal epithelium, which is critical for the absorption of substances from the gut. In summary, CBD absorption in the gut is enhanced by the presence of food, particularly fats that stimulate bile and lipase activity, improving CBD's solubility and bioaccessibility. Nanoemulsion formulations further enhance CBD absorption by overcoming its poor solubility. Additionally, the endocannabinoid system's modulation of gut permeability and motility may also influence CBD absorption.
