The peptide produces multiple biological effects and has both circulatory and neurotransmitter modes of action. In particular, it is a potent endogenous vasodilator.Cough: A sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation. It is a protective response that serves to clear the trachea, bronchi, and/or lungs of irritants and secretions, or to prevent aspiration of foreign materials into the lungs.Irritants: Drugs that act locally on cutaneous or mucosal surfaces to produce inflammation; those that cause redness due to hyperemia are rubefacients; those that raise blisters are vesicants and those that penetrate sebaceous glands and cause abscesses are pustulants; tear gases and mustard gases are also irritants.Antipruritics: Agents, usually topical, that relieve itching (pruritus).Capsicum: A plant genus of the family SOLANACEAE.

It was developed by the Sprague-Dawley Animal Company.Tachykinins: A family of biologically active peptides sharing a common conserved C-terminal sequence, -Phe-X-Gly-Leu-Met-NH2, where X is either an aromatic or a branched aliphatic amino acid. Members of this family have been found in mammals, amphibians, and mollusks. Tachykinins have diverse pharmacological actions in the central nervous system and the cardiovascular, genitourinary, respiratory, and gastrointestinal systems, as well as in glandular tissues. This diversity of activity is due to the existence of three or more subtypes of tachykinin receptors.Antitussive Agents: Agents that suppress cough. They act centrally on the medullary cough center. EXPECTORANTS, also used in the treatment of cough, act locally.Afferent Pathways: Nerve structures through which impulses are conducted from a peripheral part toward a nerve center.Vagus Nerve: The 10th cranial nerve.

The posterior nasal nerve plays an important role on cardiopulmonary reflexes to nasal application of capsaicin, distilled water and l-menthol in anesthetized dogs. (1/2233)

The sensory innervation of the cardiopulmonary reflexes to nasal application of capsaicin (CAPS), distilled water (DW) and l-menthol (LM) was studied in anesthetized dogs breathing through tracheostomy. A marked cardiopulmonary reflex was observed by CAPS and DW into the nasal cavity, while a prolongation of expiration was induced by LM. All these reflexes were significantly decreased by bilateral section of the posterior nasal nerve (PNN) and completely abolished by topical nasal anesthesia with lidocaine. Responses of the whole nerve activity of the PNN to these substances corresponded to the magnitude of the reflexes. These results indicate that PNN afferents play an important role on the reflex elicitation of the noxious, water and cold stimuli from the nasal cavity.  (+info)

C-fiber depletion alters response properties of neurons in trigeminal nucleus principalis. (2/2233)

The effects of C-fiber depletion induced by neonatal capsaicin treatment on the functional properties of vibrissa-sensitive low-threshold mechanoreceptive (LTM) neurons in the rat trigeminal nucleus principalis were examined in adult rats. Neonatal rats were injected either with capsaicin or its vehicle within 48 h of birth. The depletion of unmyelinated afferents was confirmed by the significant decrease in plasma extravasation of Evan's blue dye induced in the hindlimb skin of capsaicin-treated rats by cutaneous application of mustard oil and by the significant decrease of unmyelinated fibers in both the sciatic and infraorbital nerves. The mechanoreceptive field (RF) and response properties of 31 vibrissa-sensitive neurons in capsaicin-treated rats were compared with those of 32 vibrissa-sensitive neurons in control (untreated or vehicle-treated) rats. The use of electronically controlled mechanical stimuli allowed quantitative analysis of response properties of vibrissa-sensitive neurons; these included the number of center- and surround-RF vibrissae within the RF (i.e., those vibrissae which when stimulated elicited >/=1 and <1 action potential per stimulus, respectively), the response magnitude and latency, and the selectivity of responses to stimulation of vibrissae in different directions with emphasis on combining both the response magnitude and direction of vibrissal deflection in a vector analysis. Neonatal capsaicin treatment was associated with significant increases in the total number of vibrissae, in the number of center-RF vibrissae per neuronal RF, and in the percentage of vibrissa-sensitive neurons that also responded to stimulation of other types of orofacial tissues. Compared with control rats, capsaicin-treated rats showed significant increases in the response magnitude to stimulation of surround-RF vibrissae as well as in response latency variability to stimulation of both center- and surround-RF vibrissae. C-fiber depletion also significantly altered the directional selectivity of responses to stimulation of vibrissae. For neurons with multiple center-RF vibrissae, the proportion of center-RF vibrissae with net vector responses oriented toward the same quadrant was significantly less in capsaicin-treated compared with control rats. These changes in the functional properties of principalis vibrissa-sensitive neurons associated with marked depletion of C-fiber afferents are consistent with similarly induced alterations in LTM neurons studied at other levels of the rodent somatosensory system, and indeed may contribute to alterations previously described in the somatosensory cortex of adult rodents. Furthermore, these results provide additional support to the view that C fibers may have an important role in shaping the functional properties of LTM neurons in central somatosensory pathways.  (+info)

Mechanisms of capsaicin- and lactic acid-induced bronchoconstriction in the newborn dog. (3/2233)

1. Capsaicin activation of the pulmonary C fibre vanilloid receptor (VR1) evokes the pulmonary chemoreflex and reflex bronchoconstriction. Among potential endogenous ligands of C fibre afferents, lactic acid has been suggested as a promising candidate. We tested the hypotheses that (a) lactic acid behaves as a stimulant of C fibre receptors in the newborn dog to cause reflex bronchoconstriction, and (b) lactic acid causes reflex bronchoconstriction via the same pulmonary C fibre receptor mechanism as capsaicin using the competitive capsaicin/VR1 receptor antagonist capsazepine. 2. Right heart injection of lactic acid caused a significant increase (47 +/- 8.0 %) in lung resistance (RL) that was atropine sensitive (reduced by 75 %; P < 0.05), consistent with reflex activation of muscarinic efferents by stimulation of C fibre afferents. 3. Infusion of the competitive capsaicin antagonist capsazepine caused an 80 % reduction (P < 0.01) in the control bronchoconstrictor response (41 +/- 8.5 % increase in RL) to right heart injections of capsaicin. The effects of capsazepine are consistent with reversible blockade of the VR1 receptor to abolish C fibre-mediated reflex bronchoconstriction. 4. Lactic acid-evoked increases in RL were unaffected by VR1 blockade with capsazepine, consistent with a separate lactic acid-induced reflex mechanism. 5. We conclude that (a) putative stimulation of C fibres with lactic acid causes reflex bronchoconstriction in the newborn dog, (b) capsazepine reversibly antagonizes reflex bronchoconstriction elicited by right heart injection of capsaicin, presumably by attenuating capsaicin-induced activation of the C fibre 'capsaicin' receptor (VR1), and (c) capsazepine resistance of lactic acid-induced bronchoconstriction indicates that lactic acid evokes reflex bronchoconstriction by a separate mechanism, possibly via the acid-sensing ionic channel.  (+info)

The role of capsaicin-sensitive muscle afferents in fatigue-induced modulation of the monosynaptic reflex in the rat. (4/2233)

1. The role of group III and IV afferent fibres of the lateral gastrocnemious muscle (LG) in modulating the homonymous monosynaptic reflex was investigated during muscle fatigue in spinalized rats. 2. Muscle fatigue was induced by a series of increasing tetanic electrical stimuli (85 Hz, 600 ms) delivered to the LG muscle nerve. Series consisted of increasing train numbers from 1 to 60. 3. Potentials from the spinal cord LG motor pool and from the ventral root were recorded in response to proprioceptive afferent stimulation and analysed before and during tetanic muscle activations. Both the pre- and postsynaptic waves showed an initial enhancement and, after a '12-train' series, an increasing inhibition. 4. The enhancement of the responses to muscle fatiguing stimulation disappeared after L3-L6 dorsal root section, while a partial reflex inhibition was still present. Conversely, after section of the corresponding ventral root, there was only a reduction in the inhibitory effect. 5. The monosynaptic reflex was also studied in animals in which a large number of group III and IV muscle afferents were eliminated by injecting capsaicin (10 mM) into the LG muscle. As a result of capsaicin treatment, the fatigue-induced inhibition of the pre- and postsynaptic waves disappeared, while the response enhancement remained. 6. We concluded that the monosynaptic reflex inhibition, but not the enhancement, was mediated by those group III and IV muscle afferents that are sensitive to the toxic action of capsaicin. The afferents that are responsible for the response enhancement enter the spinal cord through the dorsal root, while those responsible for the inhibition enter the spinal cord through both the ventral and dorsal roots.  (+info)

The effects of inflammation and inflammatory mediators on nociceptive behaviour induced by ATP analogues in the rat. (5/2233)

1. We have studied the behavioural effects of intraplantar injections of adenosine 5'-triphosphate (ATP) and related compounds in freely moving rats and investigated whether these nociceptive effects are augmented in the presence of inflammatory mediators. 2. We find that in normal animals ATP and analogues produce dose-dependent nocifensive behaviour (seen as bursts of elevation of the treated hindpaw), and localized thermal hyperalgesia. The rank order of potency was: alpha,beta-methyleneadenosine 5'-triphosphate (alpha,beta-methylene ATP) > 2-methylthioadenosine triphosphate (2-methylthio ATP) > ATP. After neonatal treatment with capsaicin, to destroy small calibre primary sensory neurones, nocifensive behaviour was largely absent. 3. The effects of ATP analogues were assessed in three models of peripheral sensitization: 2 h after dilute intraplantar carrageenan (0.25% w v(-1)); 24 h after irradiation of the hindpaw with ultraviolet (U.V.) B; immediately following prostaglandin E2 (PGE2) treatment. In all models the effect of alpha,beta-methylene ATP was greatly augmented. After carrageenan, significant hindpaw-lifting behaviour activity was induced by injection of only 0.05 nmol of alpha,beta-methylene ATP, some 100 times less than necessary in normal skin. 4. Our data suggest that it is much more likely that endogenous levels of ATP will reach levels capable of exciting nociceptors in inflamed versus normal skin. Our data also suggest the involvement of P2X3 receptor subunits in ATP-induced nociception.  (+info)

Capsaicin-sensitive C-fiber-mediated protective responses in ozone inhalation in rats. (6/2233)

To assess the role of lung sensory C fibers during and after inhalation of 1 part/million ozone for 8 h, we compared breathing pattern responses and epithelial injury-inflammation-repair in rats depleted of C fibers by systemic administration of capsaicin as neonates and in vehicle-treated control animals. Capsaicin-treated rats did not develop ozone-induced rapid, shallow breathing. Capsaicin-treated rats showed more severe necrosis in the nasal cavity and greater inflammation throughout the respiratory tract than did control rats exposed to ozone. Incorporation of 5-bromo-2'-deoxyuridine (a marker of DNA synthesis associated with proliferation) into terminal bronchiolar epithelial cells was not significantly affected by capsaicin treatment in rats exposed to ozone. However, when normalized to the degree of epithelial necrosis present in each rat studied, there was less 5-bromo-2'-deoxyuridine labeling in the terminal bronchioles of capsaicin-treated rats. These observations suggest that the ozone-induced release of neuropeptides does not measurably contribute to airway inflammation but may play a role in modulating basal and reparative airway epithelial cell proliferation.  (+info)

Impact of development and chronic hypoxia on NE release from adrenergic nerves in sheep arteries. (7/2233)

To examine effects of development and chronic high-altitude hypoxia on sympathetic nerve function in sheep, norepinephrine release was measured in vitro from middle cerebral and facial arteries. Capsaicin was used to test the role of capsaicin-sensitive sensory nerves; norepinephrine release was not altered by capsaicin treatment. Nomega-nitro-L-arginine methyl ester (L-NAME), an inhibitor of NO synthase, decreased stimulation-evoked norepinephrine release in middle cerebral arteries from normoxic sheep with no effect in hypoxic arteries or facial arteries. Thus NO-releasing nerves augmented norepinephrine release. Furthermore, the function of NO-releasing nerves declined after chronic hypoxia. Despite loss of the augmenting effects of NO, stimulation-evoked fractional norepinephrine release was unchanged after chronic hypoxia, suggesting that middle cerebral arteries adapt to hypoxia by increasing stimulation-evoked norepinephrine release. In fetal facial arteries, chronic hypoxia resulted in a decline in stimulation-evoked norepinephrine release, but there was an increase in the adult facial artery. In the adult, adaptation to chronic hypoxia is similar in both cerebral and facial arteries. However, differential adaptation in fetal adrenergic nerves may reflect differences in fetal redistribution of blood flow in the face of chronic hypoxia but could also possibly contribute to increased incidence of fetal morbidity.  (+info)

Cell type-specific ATP-activated responses in rat dorsal root ganglion neurons. (8/2233)

1. The aim of our study is to clarify the relationship between expression pattern of P2X receptors and the cell type of male adult rat (Wistar) dorsal root ganglion (DRG) neurons. We identified the nociceptive cells of acutely dissociated DRG neurons from adult rats type using capsaicin sensitivity. 2. Two types of ATP-activated currents, one with fast, the other with slow desensitization, were found under voltage-clamp conditions. In addition, cells with fast but not slow desensitization responded to capsaicin, indicating that there was a relationship between current kinetics and capsaicin-sensitivity. 3. Both types of neurons were responsive to ATP and alpha, beta methylene-ATP (alpha,betameATP). The concentration of alpha,(beta)meATP producing half-maximal activation (EC50) of neurons with fast desensitization was less (11 microM) than that of neurons with slow desensitization (63 microM), while the Hill coefficients were similar. Suramin and pyridoxal-phosphate-6-azophenyl-2',4'-disulphonic acid tetrasodium (PPADS) antagonized alpha,betameATP-induced currents in both types of neurons. 4. In situ hybridization revealed that small cells of the DRG predominantly expressed mRNAs of P2X3 and medium-sized cells expressed mRNAs of P2X2 and P2X3. In contrast, both of mRNAs were not detected in large cells of the DRG. 5. These results suggest that capsaicin-sensitive, small-sized DRG neurons expressed mainly the homomeric P2X3 subunit and that capsaicin-insensitive, medium-sized DRG neurons expressed the heteromultimeric receptor with P2X2 and P2X3.  (+info)

There is both morphological and functional evidence that capsaicin-sensitive sensory neurons innervate the digestive tract. The possible function of these neurons in gastric ulceration and gastrointestinal motility was investigated in rats which had been systemically pretreated with capsaicin (50-125 mg/kg). It was found that capsaicin-sensitive afferent neurons do not participate in the physiologic control of gastrointestinal propulsion. However, the inhibition of gastrointestinal transit due to surgical trauma or peritoneal irritation with iodine was reduced in capsaicin-treated rats. It was concluded that capsaicin-sensitive sensory neurons may be involved in sympathetic reflex inhibition of gastrointestinal propulsion. Gastric ulceration induced by the intraperitoneal injection of indomethacin or intragastric administration of ethanol was greatly aggravated in capsaicin-treated rats. Since an involvement of the autonomic nervous system as well as of histamine and prostaglandins in this effect of
The present study investigated the involvement of capsaicin-sensitive sensory neurons on salt intake control in the rat, following capsaicin neonatal treatment. Capsaicin did not affect salt appetite induced by intramuscular injection of deoxycorticosterone enantate, or by intracranial injection of renin. Moreover, it did not alter salt preference of rats given access to a variety of NaCl concentrations, or the need-free salt intake of multidepleted male rats. On the other hand, in response to furosemide-induced sodium depletion, the salt intake of capsaicin-treated rats was lower than that of controls. However, furosemide-induced Na+ excretion of capsaicin-treated rats proved to be lower than that of controls, thus suggesting that difference in salt intake might be secondary to lower sensitivity of capsaicin-treated rats to the natriuretic action of furosemide. Salt intake is known to be influenced by sensory information from the oral cavity, from the liver and from the intravascular ...
Capsaicin is a compound that gives food the hot sensation. It is the most common of capsaicinoids, followed by dihydrocapsaicin, found in capsicum family of plants, which rises the heat of chillies. Other capsaicinoids present in the Capsicum fruit include nordihydro-, homo-, homodihydro-, nor-, and nornorcapsaicin. Capsaicin is the major flavouring compound, whereas capsanthin and capsorubin are major colouring compounds among variety of coloured compounds present in chile peppers. The chemical designation of capsaicin is N-vanillyl-8-methyl-6-(E)-noneamide. Capsaicin is a lipophilic white crystalline powder; melting point 60 - 65 C. Capsaicin, as a member of the vanilloids, desensitizes the sensory nerve endings giving a paradoxical antinociceptive effect. Capsaicin does not actually cause a chemical burning but a burning sensation . When nociceptors contact with capsaicin, the neuron is excited to sign the perception of pain, and there is a local release of inflammatory mediators. Capsaicin ...
95% nonivamide. Choosing between Natural Capsaicin and Synthetic Capsaicin (Nonivamide). How does one decide between the natural and synthetic forms of Capsaicin? Natural capsaicin is most often used in food and pharmaceutical preparations, whereas nonivamide is most commonly used in commercial applications such as pepper sprays and animal repellents. If it is going to be used as a deterrent, then the synthetic form is the better choice, primarily because of cost. The natural product is the result of a two-stage extraction process - solvent extraction followed by super-critical fluid extraction. As a result, the natural product costs about four times as much as the synthetic form.. Capsaicin has wide usage in the medical field for relief of pain, and more recently has been shown to be effective in fighting cancers. Aversion Technologies offers technical grade capsaicin in its pure, natural form widely used in foods and pharmaceuticals.. TYPICAL APPLICATIONS. Medicinal. Capsaicin is used in ...
TRPV1 is involved in the regulation of pain pathways (24). Capsaicin initially activates TRPV1 and excites nociceptive neurons, leading to the perception of pain. However, prolonged and repetitive exposure to capsaicin causes TRPV1 to become insensitive to noxious stimuli, resulting in desensitization (10). Thus, capsaicin-containing drugs have been developed to treat neuropathic pain through topical administration. Accumulating evidence suggests that repeated or high-dose treatments of capsaicin could cause apoptosis of TRPV1-expressing cells, primarily through the elevation of intracellular calcium ion levels (25), indicating that TRPV1-unresponsive or deficient states might be clinically important with exposure to capsaicin for a prolonged period. Because capsaicin-induced initial activation of TRPV1 is inevitably followed by desensitization, the possibility that capsaicin affects intracellular signals independently of TRPV1 cannot be excluded (26). TRPV1 expression was reportedly reduced in ...
Together, capsaicin and dihydrocapsaicin are responsible for 80 percent to 90 percent of the heat in a chili pepper. If you eat hot peppers, the capsaicin contained may aid digestion by increasing digestive fluid in the stomach and by fighting bacteria. It acts as an antioxidant, guards against heart disease, lowers cholesterol and blood pressure and can prevent clotting and hardening of the arteries. Capsaicin also thins mucus and helps remove it from the lungs. However, you might need help getting past the burning sensation before enjoying the benefits of capsaicin.
Nonivamide, also called pelargonic acid vanillylamide or PAVA, is an organic compound and a capsaicinoid. It is an amide of pelargonic acid (n-nonanoic acid) and vanillyl amine. It is present in chili peppers, but is commonly manufactured synthetically. It is more heat-stable than capsaicin. Ointment sold under trade name Finalgon is used to relieve arthritis and muscle pain. A small drop of the ointment applied on the skin is absorbed quickly causing warm to burning sensation and pain relief for several hours.[weasel words] Nonivamide is used as a food additive to add pungency to seasonings, flavorings, and spice blends. It is also used in the confectionery industry to create a hot sensation, and in the pharmaceutical industry in some formulations as a cheaper alternative to capsaicin. Like capsaicin, it can deter mammals (but not birds or insects) from consuming plants or seeds (e.g. squirrels and bird feeder seeds). This is consistent with nonivamides role as a TRPV1 ion channel agonist. ...
Background: The urge to cough is a clinical symptom of respiratory disease that precedes the motor act of coughing. Although previous studies have shown that cough is particularly susceptible to placebo suppression, it is unclear whether the perception of an urge to cough is also modifiable by placebo. Therefore, we tested the hypothesis that capsaicin-evoked urge to cough could be suppressed by placebo conditioning.Methods: Eleven healthy participants were unknowingly conditioned to believe that an inert inhaler temporarily suppressed capsaicin-induced urge to cough by deceptively modifying the challenge concentration of capsaicin. In subsequent testing, capsaicin-evoked urge-to-cough subjective ratings were assessed in four challenges with a single dose of inhaled capsaicin following no treatment or the placebo metered-dose inhaler. An additional 10 participants were informed that the inhaler therapy was inert prior to receiving capsaicin challenges with and without inhaler treatment.Results: ...
Todays post from clinicalpainadvisor.com (see link below) reveals the results of recent trials of the capsaicin (chili-based) patch Qutenza in relation to neuropathic pain. Now capsaicin is one of those treatments that regularly returns to the neuropathy forums on the internet but mostly without conclusive results. The results here can also hardly be called conclusive but they do indicate that there is benefit to be had from capsaicin patches, if applied properly. Thats the problem: its a controversial treatment because it carries the risk of potential burn issues and is both tricky to use and needs medical supervision (especially with the 8% versions that are pretty strong). Alternatives include capsaicin creams but they do tend to be messy and less effective than the patches. If you are considering trying capsaicin patches, please talk to your doctor first before ordering them on the internet. Hopefully your insurance will cover them anyway so its always best to go through the official ...

Recognition of the importance of TRPV1 and putative ligands in cancer progression has spurred interest in their exploitation as potential drug lead candidates. The TRPV1-dependent increase of intracellular reactive oxygen species (ROS) endorsed by capsaicin is known to inhibit cancer progression.27 Considering that experimental conditions often include capsaicin at concentrations several orders of magnitude higher than required for TRPV1 activation, it comes at no surprise that several mechanisms and signalling pathways, from off-target engagement, interplay in phenotype changes. In fact, it has been realized that capsaicin-induced cell death is mediated by TRPV1 at low doses in a variety of cancer cell lines, whereas TRPV1-independent effects take over from high dose and prolonged exposure.28 Interestingly, capsaicin equally promotes the production of ROS through TRPV1-independent pathways.29 Without evidence of a clear mechanism of action, 10 μM capsaicin causes G0/G1 cell-cycle arrest in ...

Capsaicin is the phytochemical substance that gives hot peppers their fiery taste. This substance is currently being investigated by researchers for its antioxidant and disease protective effects. Located in the soft, seed-bearing ribs inside chili peppers, the capsaicin (and the heat) that ends up in a recipe can be decreased by removing some or all of the ribs and seeds when you prepare the chilies. Here are a number of fiery dishes that will give you a healthy helping of capsaicin ...
The interplay of specific leukocyte subpopulations, resident cells and proalgesic mediators results in pain in inflammation. Proalgesic mediators like reactive oxygen species (ROS) and downstream products elicit pain by stimulation of transient receptor potential (TRP) channels. The contribution of leukocyte subpopulations however is less clear. Local injection of neutrophilic chemokines elicits neutrophil recruitment but no hyperalgesia in rats. In meta-analyses the monocytic chemoattractant, CCL2 (monocyte chemoattractant protein-1; MCP-1), was identified as an important factor in the pathophysiology of human and animal pain. In this study, intraplantar injection of CCL2 elicited thermal and mechanical pain in Wistar but not in Dark Agouti (DA) rats, which lack p47phox, a part of the NADPH oxidase complex. Inflammatory hyperalgesia after complete Freunds adjuvant (CFA) as well as capsaicin-induced hyperalgesia and capsaicin-induced current flow in dorsal root ganglion neurons in DA were comparable to

The capsaicin receptor (TRPV1), a heat-activated ion channel of the pain pathway, is sensitized by phosphatidylinositol-4,5-bisphosphate (PIP2) hydrolysis after phospholipase C activation. We identify a site within the C-terminal domain of TRPV1 that is required for PIP2-mediated inhibition of channel gating. Mutations that weaken PIP2-TRPV1 interaction reduce thresholds for chemical or thermal stimuli, whereas TRPV1 channels in which this region is replaced with a lipid-binding domain from PIP2-activated potassium channels remain inhibited by PIP2. The PIP2-interaction domain therefore serves as a critical determinant of thermal threshold and dynamic sensitivity range, tuning TRPV1, and thus the sensory neuron, to appropriately detect heat under normal or pathophysiological conditions.. ...

A soon to be published study by researchers from the University of Ulsan in Korea does however show that many of the companies which advertise with the afore "cited" slogans could in fact be on the right track - at least with respect to one of the key ingredients many of those topical fat-burners contain: Capsaicin, a major pungent molecule that is found in hot chilies and other peppers and has already been shown to exert direct effects on isolated adipocytes in vitro (Kang. 2007; Hsu. 2007) and anti-obesity activity in animal models (Yoshioka. 1999; Zhang. 2007). Interestingly enough, epidemiological (Wahlqvist. 2001) and controlled human trials (Bloomer. 2010) suggest that these effect do - despite the often-touted differences in the thermogenic capacity of humans and rodents - in fact manifest in all the usual steps of scientific experimentation in the medical field, i.e. the petri dish, the animal model and the controlled, randomized, placebo-blinded human trial ...

The effect of chilli powder and its pungent ingredient capsaicin on gastrointestinal transit in the rat was studied. Fasted unanaesthetized male Sprague-Dawley rats (n = 144) received by gavage a test meal containing charcoal and cellulose in water or capsaicin solvent plus 51Cr as a radioactive marker. Either 100 or 200 mg of chilli powder (containing 0.13 and 0.26 mg of capsaicin, respectively) or 0.5 or 1 mg of capsaicin were added, the final volume of each meal being 1.5 mL. At 10 and 20 min, animals were killed and the amount of isotope that had left the stomach was measured, together with the distance the charcoal column had travelled along the small intestine. Compared to controls, animals given chilli powder emptied less of their gastric content at 10 and 20 min, an effect partly reproduced by capsaicin. However overall gastric-small intestinal transit was unaffected by chilli powder or capsaicin. Another 12 male Sprague-Dawley rats received, under light ether anaesthesia, on six ...

Capsaicin has been used as a tussive agent in studies in adults to determine cough receptor sensitivity. The aim of this study was to determine the tolerance, repeatability and influence of inspiratory flow on the capsaicin cough receptor sensitivity test in children. Thirty children (mean age 11 yrs; range 6-16 yrs) were tested on two different days, to determine the lowest concentration of capsaicin required to stimulate two or more coughs (cough threshold (Cth)), 2-4 coughs (C2), and five or more coughs (C5). Capsaicin was nebulized through a dosimeter, with an arrangement that allowed the subjects to visualize and regulate their inspiratory flow. Using a constant inspiratory flow of 20 L x min(-1), tests were reproducible for C2, C5 and Cth (doubling dose changes of 1.13, 1.03 and 1.08, respectively). An increase in the inspiratory flow from 20 to 60 L x min(-1) significantly increased C2 (19.5 to 46.8 microM; p=0.016) and C5 (46.8 to 128.8 microM; p=0.008). We conclude that in children, the ...

A possible mechanism of oesophageal hypersensitivity is the acid-induced activation of transient receptor potential vanilloid receptor 1 (TRPV1) in the primary sensory neurons. We investigated TRPV1 expression and its colocalization with substance P (SP) and isolectin B4 (IB4)-positive cells in the thoracic dorsal root ganglia (DRGs) and nodose ganglia (NGs) of rats with reflux-induced oesophagitis (RO). RO was developed by fundus ligation and partial obstruction of the pylorus of Sprague-Dawley rats. Four groups of rats were used; fundus ligated acute (RO 48 h), chronic 7 days (RO 7D), RO 7D + omeprazole (7D + Omz, 40 mg kg(-1), i.p.) and sham-operated controls. Immunohistochemical analysis of TRPV1, SP and IB4 expression were carried out in spinal cord (SC), DRGs and NGs. RO rats exhibited significant inflammation and increase in TRPV1-ir and SP-ir expressions in the SC, DRGs and NGs. The maximum colocalization of TRPV1 and SP was observed in RO 7D rats, but Omz prevented inflammation and over ...

In the present study, we examined the effect of capsaicin on constitutive and induced vascular endothelial cell growth factor (VEGF) expression in malignant melanoma cells. Results: Capsaicin treatment resulted in enhanced VEGF protein secretion in malignant melanoma cells independent of IL-1β and TNF-α. The observed up-regulation of VEGF production by capsaicin was concentration- and duration-dependent and was inversely associated with inhibition of melanoma cell proliferation. We observed an increase in hypoxia-inducible factor ...
Objective: Capsaicinoids (CAPs) are the major pungent, naturally occurring active compounds in capsicum fruits such as hot chili peppers. We recently demonstrated that CAPs inhibits pancreatic lipase and down regulates C/EBPα and PPARγ. Therefore, we hypothesized that CAPS may enhance exercise by effective utilization of lipids in rats. In this study, we observed changes in protein expressions levels of NFkB, IL-10, Nrf2, pAMPK and HO-1 in rats fed a diet containing CAPs.. Methods: Eight week old male Wistar rats were treated in four treatment groups (i) control [no Ex, Group I (CTL)] (ii) CTL + CAPs [no Ex, 0.2 mg capsaicinoids from 10 mg/kg BW/day Capsimax®, Group II] (iii) CTL + Ex [Group III] and (iv) CTL + Ex+ CAPs [0.2 mg capsaicinoids from 10 mg/kg BW/day Capsimax®] for 8 wks.

Chronic unexplained cough triggered by environmental irritants is characterized by increased cough reflex sensitivity, which can be demonstrated by means of inhaled capsaicin. Topical capsaicin can be used to improve non-allergic rhinitis and intestinal hypersensitivity and to reduce neuropathic pain. Objectives: We established whether an oral intake of natural capsaicin (chilli) could desensitize the cough reflex and improve unexplained coughing. Methods: Twenty-four patients with irritant-induced, unexplained chronic cough and 15 controls were included in the study. For 4 weeks, the participants took capsules with pure capsaicin, and for 4 weeks, they took placebo capsules. The protocol was crossover, randomized, and double blind. Cough sensitivity during the study was evaluated by a standardized capsaicin inhalation cough test that assessed the capsaicin concentration required to reach two coughs (C2) and five coughs (C5). Participants were also administered questionnaires on cough and ...
1. Twelve non-smoking subjects inhaled capsaicin at three different inspiratory flow rates: 50, 100 and 150 litres/min. Capsaicin was delivered by a breath-actuated dosimeter; inhalations consisted of 0.21-13.6 nmol of capsaicin in doubling amounts given in random order.. 2. The mean number of coughs per challenge decreased with increasing inspiratory flow rate. The difference in cough numbers were significant: 7.7 (95% confidence interval 2.5-12.8) for 50 versus 100 litres/min and 10.9 (95% confidence interval 5.0-16.9) for 100 versus 150 litres/min.. 3. On a separate day, a cough threshold was measured by giving increasing doses of citric acid that were inhaled at 50 litres/min. There was a positive correlation between the sensitivity to capsaicin and the cough threshold to citric acid (r = 0.69, P = 0.01), and also between the cough latencies (r = 0.67, P = 0.02).. 4. The negative relationship between the cough response and the inspiratory flow rate may be caused by increased laryngeal ...
Capsaicin, the pungent ingredient of the hot chili pepper, is known to act on the transient receptor potential cation channel vanilloid subfamily member 1 (TRPV1). TRPV1 is involved in somatic and visceral peripheral inflammation, in the modulation of nociceptive inputs to spinal cord and brain stem centers, as well as the integration of diverse painful stimuli. In this review, we first describe the chemical and pharmacological properties of capsaicin and its derivatives in relation to their analgesic properties. We then consider the biochemical and functional characteristics of TRPV1, focusing on its distribution and biological effects within the somatosensory and viscerosensory nociceptive systems. Finally, we discuss the use of capsaicin as an agonist of TRPV1 to model acute inflammation in slices and other ex vivo preparations.. ...
Transient receptor potential vanilloid 1 (TRPV1), a non-selective cation channel, is a receptor activated by high temperatures and chemical agonists such as the vanilloids and protons. Because of these properties, TRPV1 has emerged as a polymodal nocisensor of nociceptive afferent neurons. TRPV1 is thought to be a central transducer of hyperalgesia and a prime target for controlling pain pharmacologically because it is a point where many proalgesic pathways converge and it is upregulated and sensitized by inflammation and injury. However, whether TRPV1 agonists promote or inhibit inflammation remains unclear. We recently demonstrated that SA13353 (1-[2-(1-adamantyl)ethyl]-1-pentyl-3-[3-(4-pyridyl)propyl]urea), a novel TRPV1 agonist, inhibits tumor necrosis factor-a production by the activation of capsaicin-sensitive afferent neurons and reduces the severity of symptoms in kidney injury, lung inflammation, arthritis, and encephalomyelitis. These results suggest that TRPV1 agonists may act as anti

Capsaicinol is an ingredient of hot red pepper. In this study, we developed a novel method for capsaicinol synthesis and examined capsaicinols physiological effects on capsaicin receptor (TRPV1)-related actions. Allylic oxidation of capsaicin by palladium acetate (Pd(OAc),SUB,2,/SUB,) resulted in the formation of (±)-capsaicinol acetate at a 7.2% yield in a single step. The effectiveness of (±)-capsaicinol in TRPV1 activation (EC,SUB,50,/SUB,=1.1 μ,small,M,/small,) was found to be weaker than that of capsaicin (EC,SUB,50,/SUB,=0.017 μ,small,M,/small,), whereas the efficacy of (±)-capsaicinol reached 75% of that of capsaicin. Intravenous administration of (±)-capsaicinol in anesthetized rats dose-dependently enhanced adrenaline secretion from the adrenal gland. The response to a 5 mg/kg-dose of (±)-capsaicinol was comparable to that of a 0.05 mg/kg-dose of capsaicin. The relative pungency of capsaicinol to capsaicin was coincident with the relative effectiveness in inducing these ...
It may be quite possible that consuming too much Sriracha or any other hotter chili pepper over a period of time may stunt hair growth or cause your hair to go into premature catagen phase. Based on available scientific information, TRVP1 exposure to capsaicin causes excessive heat, abrasive damage and inflammation to nerves. Nerves are present around hair follicles and act as receptors to pain stimuli. In case of extreme exposure, capsaicin acts as an inflammatory stimulus, which triggers an inflammatory response by the body, which can lead to tissue damage.. According to research, capsaicin can lead to reduction in sensory function, and sensory nerve fibers. Thus, as TRVP1 is heavily present around hair follicles, sensory nerve endings, dermal blood vessels, sebaceous glands, mast cells, etc., inflammation caused by a high concentration of capsaicin can cause adverse effects to sensory nerves and tissues surrounding hair follicles. Over time, sensory nerve damage (sensory neuropathy) can cause ...

The present study demonstrated for the first time that neonatal degeneration of capsaicin-sensitive sensory nerves in rats leads to a significant increase in blood pressure when a high sodium diet is given. This observation is important because it has been shown that (1) substantial decreases in CGRP-containing sensory nerves in the mesenteric arterial bed occur in spontaneously hypertensive rats (SHR),6 7 indicating that there are inherited abnormalities in either generation or maintenance of sensory nerves in SHR; (2) the plasma CGRP concentration is lower in adult SHR than in age-matched normotensive control rats, indicating that release of CGRP from sensory nerves is decreased in SHR21 ; and (3) vasodilator responses to exogenous CGRP increase with age in SHR, suggesting that sensitivity of receptors to CGRP is increased due to the decreased release of CGRP from sensory nerves.6 7 The defect in sensory vasodilator function may produce an imbalance that could contribute to the development and ...

Difficulty: Easy. Hot Cayenne pepper is best known for its fiery zesty taste when used as a condiment in food preparation. It, however, is packed with healing properties thanks to the high concentration of capsaicin. Capsaicin is a potent anti-inflammatory and when used for the home treatment of sciatic nerve pain, it plays a key role in mediating the relief and making the condition more bearable. This works because the capsaicin inhibits the action of a nerve compound known as substance P which is known to facilitate for the transmission of pain signals.. The best news, perhaps, is the fact that the hotter the pepper is, the more potent the healing properties. Research also indicates that regular use of the remedy makes its effects more profound. Listed below are the steps you are required to follow to prepare your own capsaicin cream. If, however, this is not possible, you need to get capsaicin cream from the nearest chemist. For the latter, look out for a skin cream that contains anywhere ...
Capsaicin-sensitive nerves mediate axon vasodilator reflexes in the intestine but the ion channels underlying action potential (AP) propagation are poorly understood. To examine the role of voltage gated Na+ channels underlying these reflexes, we measured vasomotor and electrophysiological responses elicited by capsaicin in guinea pig and mouse dorsal root ganglia neurons, submucosal arterioles and mesenteric arteries in vitro. TRPV1 agonists dilated guinea pig ileal submucosal arterioles and were blocked by capsazepine and ruthenium red. In double chamber baths, capsaicin-evoked activation of TRPV1 on proximal perivascular nerves in the left chamber evoked dilations of the distal segment of the submucosal arteriole in the right chamber. Dilations were TTX (1 μM) resistant but reducing extracellular Na+ (10% solution) or applying the Nav 1.8 antagonist A-803467 (1 μM) in the proximal chamber blocked capsaicin-evoked dilations in the distal chamber (88%; P = 0.01 and 75%, P,0.02 respectively). ...

Chili peppers can be used as a source for producing biofuel, just like any other biomass. Biomass is material derived from living or recently dead organisms, such as crops, waste, wood and paper, alcohol, and so on.. There is no reason to specifically single out chili peppers though. If youre thinking about the burning taste associated with hot peppers, it has nothing to do with actual heat. Chemicals called capsaicinoids, that are found in those peppers, just happen to activate receptors on nerve endings in human tissue that normally react to heat and physical abrasion. So the perception of heat is merely a sensation and does not indicate a high temperature.. ...
Obesity is a leading cause of metabolic syndrome. The growing endemic of diet-induced obesity necessitates the development of novel strategies to counter obesity. Recent research suggests a regulatory role of transient receptor potential vanilloid 1 (TRPV1) in diet-induced obesity. Here, we evaluated the hypothesis that capsaicin (CAP), a TRPV1 agonist, inhibited high fat diet (HFD)-induced obesity by inducing browning of white adipose tissue (WAT).. Dietary CAP (0.01% of HFD) significantly prevented obesity in wild type (WT) but not in TRPV1-/- mice without modifying the food/water intake in these mice. CAP increased the expression of the brown fat-specific thermogenes, peroxisome proliferator-activated receptor gamma (PPARγ) coactivator 1 alpha, uncoupling protein-1 and bone morphogenetic protein b8 in the subcutaneous and brown fat pads of WT mice in vivo. Furthermore, CAP increased the expression of sirtuin-1 (SiRT-1 deacetylase) and PR domain protein 16 (PRDM-16-gene responsible for the ...
Chili peppers can do more than just make you feel hot, reports a study in the August 1 Journal of Biological Chemistry; the active chemical in peppers can directly induce thermogenesis, the process by which cells convert energy into heat.. Capsaicin is the chemical in chili peppers that contributes to their spiciness; CPS stimulates a receptor found in sensory neurons, creating the heat sensation and subsequent reactions like redness and sweating.. Now, Yasser Mahmoud has found that capsaicin can create "heat" in a more direct manner by altering the activity of a muscle protein called SERCA. Normally, muscle contraction initiates following the release of a wave of calcium ions from a compartment called the sarcoplasmic reticulum (SR); SERCA then actively pumps the calcium back into the SR (using ATP energy), causing muscle relaxation and renewing the cycle.. Capsaicin, however, can attach to SERCA and "uncouple" this pumping activity; that is, the protein still burns ATP energy but doesnt use ...

Although water stress reduces fruit yield, it also increases capsaicinoid accumulation in hot pepper. The aim of this study was to investigate the effect of different water regimes on capsaicinoid production in Capsicum chinense Jacq. having different pungency levels. Four hot pepper (C. chinense) cultivars were planted with four water regimes after anthesis: daily irrigation (control; S1), every 2 days (S2), every 3 days (S3) and every 4 days (S4). The results found that Akanee Pirote with the S2 treatment gave the highest capsaicinoid yield, and the increase of capsaicinoid yield was attributed from increasing the absolute capsaicinoid content and reducing the dry fruit yield as compared to the control ...
Red chili peppers capsaicin, the compound responsible for their pungent heat, stops the spread of prostate cancer cells through a variety of mechanisms, indicates a study published in the March 15, 2006 issue of Cancer Research . Capsaicin triggers suicide in both primary types of prostate cancer cell lines, those whose growth is stimulated by male hormones and those not affected by them. In addition, capsaicin lessens the expression of prostate-specific antigen (PSA), inhibits the ability of the most potent form of testosterone, dihydrotestosterone, to activate PSA, and directly inhibits PSA transcription, causing PSA levels to plummet ...
BioAssay record AID 537199 submitted by ChEMBL: Antagonist activity at rat TRPV1 expressed in CHO cells assessed as inhibition of capsaicin-induced calcium uptake.
Currently the TRPV family has six members grouped into three subfamilies. TRPV1 and TRPV2 are the vanilloid receptors and vanilloid-like receptors, VR-1 and VRL-1, respectively. TRPV4 is the osm-9-like OTRPC4, and TRPV5 and TRPV6 are the Ca2+-selective channels, ECaC1/CaT2 (Epithelial Calcium Channel/Calcium Transporter) and ECaC2 (also called CaT1).. The vanilloid receptors are the most well understood ion channels in this class (Caterina and Julius, 2001). VR-1 (TRPV1) is activated by the "hot" pepper-derived vanilloid compound capsaicin (Caterina et al., 1997) but is not activated by store depletion. The expressed capsaicin receptor is a relatively Ca2+-selective ion channel with an outwardly rectifying I-V relation and exhibits Ca2+-dependent desensitization. Endogenous cannabinoids receptor ligands, such as anandamide, are potential TRPV1 agonists. The exact mechanism of TRPV1 activation is not completely understood, but it is sensitive to heat (,43°C), but the temperature at which it is ...
A regular Habanero hot sauce averages about 20,000 to 30,000 Scoville units. The "extract" sauces (usually named stuff like Devils Drool, or Blairs Mega Death, and have entertaining packaging) contain much higher concentrations of Capsaicin extract and range from 250,000 to 550,000 Scoville units. Needless to say that is extremely hot. So much so they carry warnings that they are to be dilluted and used on a per drop basis, and should be kept in a safe place. Generally 300,000 to 550,000 Scoville unit sauces are the apex of heat for even the seasoned "chileheads", and will undoubtedly induce a lot of sweating, eye tearing and nasal drip for a good 10 minutes or so in small applications. The Black Mamba however is in a group of maybe four or five in the world that carry the highest concentraions of Capsaicin at inordinately high levels. Black Mamba was tested and shown to have several million Scoville units per bottle! What this means is a toothpick sized droplet will burn burn burn in a way ...

Becoming popular 1970s, HPLC is a method of separating compounds within a solution under high pressure. Once the solution has been separated, the parts can be identified and quantified. Applying HPLC can be used on ground peppers, chemists can determine the capsaicinoid concentration in parts per million. The capsaicin concentrating in parts per million is directly proportional to the Scoville rating system - by a factor of approximately 16. Thus, a capsaicinoid level of 200 parts per million results in a Scoville rating of 3200. Pure capsaicin would then have a Scoville rating of 16 million. The downside of HPLC is that it is quite expensive compared to having a bunch of people tasting chile flavored Frutopia ...

You add hot, spicy foods to your diet because you enjoy the flavor, but you might be unaware of the possible health benefits of capsaicin, one of the natural compounds in these foods.
Chili peppers produce capsaicin, the pungent substance that gives the fruit its heat, as a chemical weapon to beat back invading Fusarium fungi and to protect their seeds. However, in dry conditions, the fungi do not thrive and so the plants do not need to produce as much capsaicin to protect themselves. In wetter regions in which the fungus thrives, the pepper plants spice up their defenses. There is a major physiological trade-off, however. Pungent plants have reduced efficiency in water use, so make fewer seeds in dryer areas. Non-pungent plants in wetter areas, make more seeds but these are more likely to be attacked by fungus.. ...

1. Encourage weight loss. Hot peppers comprise of capsaicin, which speeds up the metabolism and assists the body to burn calories at a faster rate. Capsaicin works by increasing the temperature in the body, contributing to a significant increase in heart rate. In addition, studies clearly show that individuals who consume spicy foods only consume small portions of food, which lowers their overall intake of calories.. 2. Cardiovascular benefits. Spicy food can also help to enhance heart health through improving the capability of the body of dissolving blood clots. Scientists found that LDL cholesterol resisted oxidation, which causes arterial clogging, when hot peppers were introduced into the diet . This lowers the risk of getting heart attacks and strokes. The capsaicin present in hot peppers also combats inflammation, helping to lower heart disease risk. Statistics also show that people who frequently consume spicy foods have lower rates of strokes.. 3. Prevents cancer. Consuming curry and ...
Capsaicin is tasteless and odorless. As mammals, we feel the pain (so good!) of capsaicin in certain pain receptors (or nociceptors - L. nocere, harm; capere, to take hold - source). And not just on our tongues, and thats all that needs to be mentioned with respect to that. But birds have very little sensitivity to capsaicin. Its been a good way for chili plants to screen out the less desirable fruit consumers: those who cant fly, hence would be pretty useless in dispersing the seeds. It doesnt discourage us, of course, and we havent been able to fly until recently. But we farm, so were OK.. (source). Scoville scale @Wikipedia. ...

ABSTRACT: We are interested in determining the molecular basis of somatosensation - the process whereby we experience touch and temperature - with an emphasis on identifying molecules that detect noxious (pain-producing) stimuli. We are also interested in understanding how somatosensation is altered in response to tissue or nerve injury. Our approach has been to identify molecular targets for natural products that mimic the psychophysical effects of commonly encountered somatosensory stimuli, such as heat or cold, and to then ask how these molecules are activated or modulated by noxious stimuli or injury.. We have focused on three members of the TRP channel family (TRPV1, TRPM8, and TRPA1) that are expressed by subpopulations of primary afferent sensory neurons and which have been implicated in the detection of thermal stimuli and/or inflammatory agents. Genetic studies support the idea that the capsaicin receptor (TRPV1) and the menthol receptor (TRPM8) function as detectors of heat and cold, ...

Heres what the stuff in cayenne pepper-and other hot peppers-can (probably) do for your overall health and fitness, and where they might fall short.
HOT peppers have been used for centuries as a remedy for various ailments. Modern clinicians use the active ingredient capsaicin most commonly to relieve pain. Topical application of capsaicin to skin or mucus membranes and intrathecal administration causes the release and ultimate depletion of substance P and calcitonin gene-related peptide. 1-5 This response is thought to be the antecedent to pain relief when used for pain reduction. Capsaicin (trans -8-methyl-N -vanillyl-6-nonenamide) is a specific excitant of unmyelinated afferent fibers (C fibers). Because most C fibers conduct nociceptive impulses and produce acute symptoms that mimic some chronic pain syndromes, such as complex regional pain syndrome types I and II, capsaicin has been used as a probe to study the mechanisms of pain generation. An intradermal injection of a small amount of capsaicin evokes an intensely painful, burning sensation. The skin overlying the bleb raised by the injection is insensitive to noxious stimuli, but ...
The transient receptor potential cation channel subfamily V member 1 (TrpV1), also known as the capsaicin receptor and the vanilloid receptor 1, is a protein that, in humans, is encoded by the TRPV1 gene. It was the first isolated member of the transient receptor potential vanilloid receptor proteins that in turn are a sub-family of the transient receptor potential protein group. This protein is a member of the TRPV group of transient receptor potential family of ion channels. The function of TRPV1 is detection and regulation of body temperature. In addition, TRPV1 provides a sensation of scalding heat and pain (nociception). TRPV1 is a nonselective cation channel that may be activated by a wide variety of exogenous and endogenous physical and chemical stimuli. The best-known activators of TRPV1 are: temperature greater than 43 °C (109 °F); acidic conditions; capsaicin, the irritating compound in hot chili peppers; and allyl isothiocyanate, the pungent compound in mustard and wasabi. The ...
Isocapnic dry gas hyperpnea causes bronchoconstriction in guinea pigs that is mediated by release of tachykinins from airway sensory nerves. Exogenous neuropeptides can induce microvascular leak. Therefore we tested whether dry gas hyperpnea also elicits bronchovascular hyperpermeability by measuring Evans blue-labeled albumin extravasation along the airways of mechanically ventilated guinea pigs. We found that 1) room temperature dry gas hyperpnea increased Evans blue extravasation in extrapulmonary and intrapulmonary airways as a specific consequence of local airway heat/water losses, 2) capsaicin pretreatment ablated the bronchoconstrictor response to dry gas hyperpnea and reduced bronchovascular leak only in intrapulmonary airways, 3) phosphoramidon given to capsaicin-pretreated animals partially restored dry gas hyperpnea-induced bronchoconstriction and increased the vascular hyperpermeability response to hyperpnea in intrapulmonary airways, and 4) propranolol administration had no important

I had a bit of goats cheese to use and I was thinking about just crumbling it over a salad but then I thought, no I can do something more creative with this. While I was looking through my fridge for ideas I noticed some of the red peppers that I had roasted and frozen in the fall and I knew that the sweet and smoky roasted red peppers would go perfectly with the tangy goat cheese. Right beside the red peppers was some bread and I recalled my experiments with pestos in grilled cheese sandwiches and I knew that I would have to try making a grilled goat cheese and roasted red pepper pesto sandwich. Five minutes later I had a batch of roasted red pepper pesto and a few minutes after that I was enjoying a little piece of heaven in my mouth, well, after taking some photographs that is. I made sure to bring the goat cheese up to room temperature before making the sandwich and by the time it came off the grill pan it was just starting to get all melty and good!

AU - Hsieh, Hui Ya. AU - Dodd, Emily G.. AU - Nguyen, Loi T.. AU - Balkowiec, Agnieszka. PY - 2006/12/1. Y1 - 2006/12/1. N2 - Activity-dependent plasticity in nociceptive pathways has been implicated in pathomechanisms of chronic pain syndromes. Calcitonin gene-related peptide (CGRP), which is expressed by trigeminal nociceptors, has recently been identified as a key player in the mechanism of migraine headaches. Here we show that CGRP is coexpressed with brain-derived neurotrophic factor (BDNF) in a large subset of adult rat trigeminal ganglion neurons in vivo. Using ELISA in situ, we show that CGRP (1-1000 nm) potently enhances BDNF release from cultured trigeminal neurons. The effect of CGRP is dose-dependent and abolished by pretreatment with CGRP receptor antagonist, CGRP(8-37). Intriguingly, CGRP-mediated ...

AU - Cohen, David. PY - 2006/5. Y1 - 2006/5. N2 - We identified a consensus N-linked glycosylation motif within the pore-forming loop between the fifth and sixth transmembrane segments of the osmoresponsive transient receptor potential (TRP) channel TRPV4. Mutation of this residue from Asn to Gln (i.e., TRPV4N651Q) resulted in loss of a slower migrating band on anti-TRPV4 immunoblots and a marked reduction in lectin-precipitable TRPV4 immunoreactivity. HEK293 cells transiently transfected with the mutant TRPV4N651Q exhibited increased calcium entry in response to hypotonic stress relative to wild-type TRPV4 transfectants. This increase in hypotonicity responsiveness was associated with an increase in plasma membrane targeting of TRPV4N651Q relative to wild-type TRPV4 in both HEK293 and COS-7 cells but had no ...
