Summary
Purinergic signaling, involving ATP, plays a key role in pain perception. This review explores purinergic receptors and their therapeutic potential for visceral and neuropathic pain.
Area of Science:
- Neuroscience
- Pharmacology
- Cell Biology
Background:
- Overview of purinergic signaling, adenosine triphosphate (ATP) storage, release, and breakdown.
- Classification of purine and pyrimidine receptor subtypes.
- Established role of purinergic signaling in pain pathways.
Purpose of the Study:
- To review purinergic mechanosensory transduction in visceral, cutaneous, and musculoskeletal nociception.
- To examine the involvement of specific purinergic receptors (P2X3, P2Y2/3, P2X4, P2X7, P2Y12) in neuropathic and inflammatory pain.
- To discuss current therapeutic strategies targeting purinergic pathways for pain management.
Main Methods:
- Literature review of early background studies on purinergic signaling and pain.
- Focus on research detailing purinergic receptor subtypes and their functions.
- Analysis of current developments in therapeutic compound discovery for pain treatment.
Main Results:
- Purinergic signaling is integral to nociception across different tissues.
- Specific P2X and P2Y receptors are implicated in the pathophysiology of neuropathic and inflammatory pain.
- Emerging therapeutic compounds show promise for treating visceral and neuropathic pain.
Conclusions:
- Purinergic signaling pathways are critical targets for pain therapeutics.
- Understanding the roles of specific purinergic receptors can guide the development of novel analgesics.
- Further research into purinergic receptor modulation holds significant potential for managing chronic pain conditions.

01:25Analgesia and Pain Management
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
01:20Pain
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
01:22Opioid Receptors: Overview
Opioid receptors, including the mu (μ, MOR), delta (δ, DOR), and kappa (κ, KOR) types, belong to the rhodopsin family of G protein-coupled receptors. These receptors are located throughout the central and peripheral nervous systems and in non-neuronal tissues such as macrophages and astrocytes. Opioid receptor ligands can be categorized into agonists or antagonists. Highly selective agonists include [d-Ala2, MePhe4, Gly(ol)5]-enkephalin or DAMGO for MOR, [D-Pen2, D-Pen5]-enkephalin or DPDPE for...
01:44Nociception
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain. Thus, pain helps the...
01:12Mechanically-gated Ion Channels
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...
01:21G-protein Coupled Receptors
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.
