Gene Information

Application

Resiniferatoxin has been used as an agonist to transient receptor potential vanilloid 2 (TRPV2):
  • for complex preparation for cryo-electron microscopy structural studies
  • to test its effect towards immune responses to P. aeruginosa in sensory neurons associated with the cornea
  • to study its effects in the denervation of the peripheral sensory nerves in psoriatic mice

Biochem/physiol Actions

Potent VR1 vanilloid receptor agonist that has been used to label the vanilloid receptor in sensory ganglia; activates protein kinase C. Diterpene ester that is related to phorbol, but is not tumorigenic.
Resiniferatoxin (RTX) is an analog of capsaicin. It effectively ablates corneal sensory neurons by activating transient receptor potential vanilloid 1 (TRPV1) channels. RTX facilitates corneal bacterial clearance. It also elicits protective functionality towards cardiac function in a rat model with congestive heart failure (CHF).

Patients suffering from sensory neuropathy due to skin denervation frequently have paradoxical manifestations of reduced nociception and neuropathic pain. However, there is a lack of satisfactory animal models to investigate these phenomena and underlying mechanisms. We developed a mouse system

Pharmacological treatment of the overactive bladder relies on partially blocking the efferent parasympathetic innervation to the detrusor with anticholinergic drugs. However, often these drugs have troublesome side effects and doses are insufficient to restore continence in patients with detrusor instability.

Resiniferatoxin, an ultrapotent capsaicin analog present in the latex of Euphorbia resinifera, interacts at a specific membrane recognition site (referred to as the vanilloid receptor), expressed by primary sensory neurons mediating pain perception as well as neurogenic inflammation.

In primary sensory neurons, the capsaicin receptor TRPV1 functions as a molecular integrator for a broad range of seemingly unrelated chemical and physical noxious stimuli, including heat and altered pH. Indeed, TRPV1 is thought to be a major transducer of

With 336 reviews, the capsaicin receptor TRPV1 arguably represent today's most extensively reviewed analgesic target. TRPV1 is strategically located at the peripheral terminals of primary sensory neurons where pain is generated. TRPV1 as a target for analgesic drugs has been
