Summary
Chronic visceral pain involves complex mechanisms at the dorsal root ganglia (DRG). Targeting ATP-sensitive purinergic and TRPV1 receptors in primary afferent neurons offers novel therapeutic strategies for pain relief.
Area of Science:
- Neuroscience
- Pain Research
- Molecular Biology
Background:
- Chronic visceral pain significantly impacts patient quality of life, often co-occurring with psychiatric disorders.
- Understanding nociception mechanisms is crucial for treating chronic pain-associated diseases.
- Inflammatory mediators activate nociceptors via ion channels and signaling pathways.
Purpose of the Study:
- To review recent advancements in the peripheral modulation of chronic pain.
- To elucidate the role of primary afferent neurons in pain transmission.
- To explore novel therapeutic targets for visceral pain relief.
Main Methods:
- Focus on research examining peripheral modulation of chronic pain.
- Utilizes in vitro and in vivo studies of primary afferents in dorsal root ganglia (DRG).
- Highlights studies defining the role of specific receptors in nociceptive pathways.
Main Results:
- Primary afferent neurons in DRG are key in nociceptive pathways.
- ATP-sensitive purinergic and vanilloid-sensitive TRPV1 receptors play significant roles.
- Heterogeneity of nociceptive neurons influences pain transmission.
Conclusions:
- Peripheral modulation of visceral primary afferent neurons is a promising area for pain management.
- Targeting specific receptors like TRPV1 offers potential for novel anti-nociceptive therapies.
- Developing targeted therapies can significantly improve patient outcomes and reduce treatment burden.

01:25Analgesia and Pain Management
786
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...

01:44Nociception
29.4K
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.

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...

2.1K
Parasympathetic signaling plays a crucial role in regulating various physiological processes. It involves the release of acetylcholine (ACh) by parasympathetic neurons, which can have localized and short-lived effects. The majority of ACh released is rapidly inactivated at the synapse by the enzyme acetylcholinesterase (AChE), which hydrolyzes Ach into choline and acetate. Additionally, the tissue cholinesterase deactivates any ACh diffusing into the surrounding tissues.
