Summary
Transient receptor potential vanilloid 1 (TRPV1) channels sense pain and injury. Modulating TRPV1 activity offers potential treatments for chronic pain, neuropathy, and hearing loss.
Area of Science:
- Physiology
- Pharmacology
- Neuroscience
Background:
- Transient receptor potential vanilloid 1 (TRPV1) is a multimodal sensor on sensory neurons, activated by heat, protons, capsaicin, and endovanilloids.
- TRPV1 activation is implicated in chronic inflammatory pain, diabetic neuropathy, and conditions like cystitis, asthma, and hearing loss.
Purpose of the Study:
- To review the physiological and pathophysiological roles of TRPV1 in various organs.
- To highlight the clinical potential of drugs targeting TRPV1.
Main Methods:
- Literature review of TRPV1 function in normal physiology and disease states.
- Analysis of existing research on TRPV1's involvement in pain, neuropathy, and organ-specific diseases.
Main Results:
- TRPV1 acts as a sensor for noxious stimuli, contributing to pain and injury avoidance.
- Dysregulation of TRPV1 is linked to chronic pain conditions and non-neuronal diseases.
- TRPV1 expression is found in sensory neurons and non-neuronal tissues like the bladder, lungs, and cochlea.
Conclusions:
- TRPV1 plays a significant role in both normal physiology and disease pathophysiology.
- Targeting TRPV1 with therapeutic agents presents a promising strategy for treating a range of conditions, including chronic pain and hearing loss.

01:43Thermosensation
29.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:15G Protein-coupled Receptors
14.0K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

9.2K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

01:20Antiepileptic Drugs: Modulators of Neurotransmitter Release Mediated by SV2A Protein
1.2K
Antiepileptic drugs, such as levetiracetam (Keppra) and brivaracetam (Briviact), have emerged as crucial tools in managing epilepsy. These medications exert their therapeutic effects by targeting the synaptic vesicle protein SV2A, a transmembrane glycoprotein primarily found in the brain.
SV2A is a transmembrane glycoprotein located predominantly in the brain, modulating the release of neurotransmitters for neuronal communication. Both levetiracetam and brivaracetam exhibit a high affinity for...
