Summary
Nerve growth factor (NGF) is a key mediator of inflammatory pain, with potential therapeutic applications. Brain-derived neurotrophic factor (BDNF) also plays a role in pain modulation and central sensitization.
Area of Science:
- Neuroscience
- Pain Research
- Molecular Biology
Context:
- Neurotrophins, including nerve growth factor (NGF), are crucial for neuronal development and survival.
- Extensive research highlights NGF's role as a peripheral mediator in inflammatory and persistent pain states in humans and animal models.
- Increased NGF synthesis is observed in various inflammatory diseases, and NGF-neutralizing agents show analgesic effects.
Purpose:
- To explore the role of neurotrophins, specifically NGF and BDNF, in pain pathways.
- To review the therapeutic potential and challenges of targeting NGF for pain management.
- To understand the interplay between NGF and BDNF in nociception and central sensitization.
Summary:
- NGF is a peripheral mediator of inflammatory pain, with elevated levels in inflammatory conditions.
- Therapeutic strategies targeting NGF showed promise in clinical trials but were halted due to safety concerns.
- NGF influences the expression of BDNF in nociceptors, which modulates pain in the central nervous system and contributes to central sensitization.
Impact:
- Highlights NGF's significance in pain signaling and its potential as an analgesic target.
- Underscores the complexities and safety considerations in developing NGF-based pain therapies.
- Elucidates the interaction between peripheral and central neurotrophic factors in pain perception and chronification.

28.4K
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.

01:20Pain
2.1K
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...

01:25Analgesia and Pain Management
3.3K
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...

01:29Blood and Nerve Supply to the Bones
15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
1.7K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
