Topical capsaicin was found in a meta-analysis to provide a degree of pain relief to some patients with painful neuropathic conditions.
The major findings of this study are that mice with only one functional allele of the type III Nrg1 gene lack multiple aspects of excitatory synaptic plasticity in cortical-BLA circuits. Specifically, in type III Nrg1 heterozygotes, cortical-BLA synapses failed to potentiate in response to either HFS (Fig. 3 vs Fig. 4) or TBS in combination with brief exposure to low concentrations of nicotine, conditions that reliably induce sustained potentiation of synaptic transmission in WT littermates (Fig. 7) (Jiang and Role, 2008). This latter result was phenocopied in α7*nAChR heterozygotes (Fig. 7). In addition to these dramatic changes in plasticity, more subtle differences between type III Nrg1 heterozygotes and WT mice were seen in terms of baseline synaptic transmission. Most notably, we found a decrease in NMDA/AMPA ratio, largely driven by increased AMPA receptor-mediated synaptic current amplitude (Fig. 2), an accelerated rate of decay of mEPSCs (Fig. 1), and a failure of nicotine to increase ...

N2 - Cancer colonization of bone leads to the activation of osteoclasts, thereby producing local tissue acidosis and bone resorption. This process may contribute to the generation of both ongoing and movement-evoked pain, resulting from the activation of sensory neurons that detect noxious stimuli (nociceptors). The capsaicin receptor TRPV1 (transient receptor potential vanilloid subtype 1) is a cation channel expressed by nociceptors that detects multiple pain-producing stimuli, ...
Transient receptor potential vanilloid-1 (TRPV1) is a member of the TRP family of channels that are responsible for nociceptive, thermal, and mechanical sensations. Originally associated exclusively with sensory neurons, TRPV1 is now known to be present in almost all organs, including cells of the immune system, where TRPV1 has been shown to play a pivotal role in inflammation and immunity. Monocytes, macrophages, and dendritic cells express TRPV1, with both mouse and human studies suggesting that TRPV1 activation protects against endotoxin-induced inflammation. In contrast, TRPV1 (and other TRP channels) appears to be required for T-cell receptor activation by mitogens. Additionally, studies in cell lines derived from hematological and other malignancies suggest altered expression/function of TRPV1 might serve as a target for novel cytotoxic therapies.. ...

Intracellular calcium-permeable channels have been implicated in thermogenic function of murine brown and brite/beige adipocytes, respectively transient receptor potential melastin-8 and transient receptor potential vanilloid-4. Because the endo-lysosomal two-pore channels (TPCs) have also been ascribed with metabolic functionality, we studied the effect of simultaneously knocking out TPC1 and TPC2 on body composition and energy balance in male mice fed a chow diet. Compared with wild-type mice, TPC1 and TPC2 double knockout (Tpcn1/2(-/-)) animals had a higher respiratory quotient and became obese between 6 and 9 months of age. Although food intake was unaltered, interscapular brown adipose tissue (BAT) maximal temperature and lean-mass adjusted oxygen consumption were lower in Tpcn1/2(-/-) than in wild type mice. Phosphorylated hormone-sensitive lipase expression, lipid density and expression of β-adrenergic receptors were also lower in Tpcn1/2(-/-) BAT, whereas mitochondrial respiratory chain

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 ...

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.

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 ...
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
Hydrogen sulfide (H,sub,2,/sub,S), a malodorous gas with the characteristic odor of rotten eggs, has been recognized as an important endogenous gaseous signaling molecule of the cardiovascular, gastrointestinal, genitourinary, and nervous systems. Besides acting as a potent vasodilator and an atypical neuromodulator, H,sub,2,/sub,S is increasingly being established as a novel mediator of inflammation. However, the part played by H,sub,2,/sub,S in modulating neurogenic inflammatory response in sepsis is not known. Therefore, this study aimed to investigate the role of H,sub,2,/sub,S in mediating neurogenic inflammation in a mouse model of polymicrobial sepsis induced by cecal ligation and puncture (CLP). Of major significance in the development of neurogenic inflammation is the transient receptor potential vanilloid type 1 (TRPV1) receptor, a non-selective cation channel found predominantly in primary sensory neurons. In particular, the results of the present study indicate that H,sub,2,/sub,S ...

A class of drugs producing both physiological and psychological effects through a variety of mechanisms. They can be divided into "specific" agents, e.g., affecting an identifiable molecular mechanism unique to target cells bearing receptors for that agent, and "nonspecific" agents, those producing effects on different target cells and acting by diverse molecular mechanisms. Those with nonspecific mechanisms are generally further classed according to whether they produce behavioral depression or stimulation. Those with specific mechanisms are classed by locus of action or specific therapeutic use. (From Gilman AG, et al., Goodman and Gilmans The Pharmacological Basis of Therapeutics, 8th ed, p252 ...
Transient receptor potential vanilloid 4 (TRPV4) channels are expressed in brain neurons involved in systemic osmoregulation; and intravenous administration of TRPV4 channel antagonists elevates arterial pressure in peripheral. Here, we examined the role of TRPV4 in the regulation of blood pressure and neuronal activity in the PVN of Dahl S and Dahl R rats. Microinjection of TRPV4 antagonists, HC067047 (10 uM, in 50 nl) or ruthenium red (10 uM, in 50 nl), into the PVN significantly increased mean arterial pressure (MAP) and heart rate (HR) in both Dahl R and Dahl S rats on either high salt or normal diet. However, the pressor and tachycardia effects of TRPV4 channel blockers were significantly impaired in Dahl S rats on high salt diet as compared with other groups of rats. In contrast, PVN microinjection of the TRPV4 agonist, GSK1016790A (100 nM, in 50 nl), markedly reduced MAP and HR in all groups of rats. The depressor and bradycardia effects induced by TRPV4 stimulation were significantly ...
The aggressive behavior of Glioblastoma multiforme (GBM) is mainly due to high invasiveness and proliferation rate as well as to high resistance to standard chemotherapy. Several chemotherapeutic agents like temozolomide (TMZ), carmustine (BCNU) or doxorubicin (DOXO) have been employed for treatment of GBM, but they display limited efficacy. Therefore, it is important to identify new treatment modalities to improve therapeutic effects and enhance GBM chemosensitivity. Recently, activation of the transient receptor potential vanilloid type 2 (TRPV2) has been found to inhibit human GBM cell proliferation and overcome BCNU resistance of GBM cells. Herein, we evaluated the involvement of cannabidiol (CBD)-induced TRPV2 activation, in the modulation of glioma cell chemosensitivity to TMZ, BCNU and DOXO. We found that CBD increases TRPV2 expression and activity. CBD by triggering TRPV2-dependent Ca2+ influx increases drug uptake and synergizes with cytotoxic agents to induce apoptosis of glioma cells, ...

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 ...
