[Neurogenic inflammation. I. Basic mechanisms, physiology and pharmacology]

Area of Science:

• Neuroscience
• Inflammation Research
• Pharmacology

Background:

• Noxious stimuli activate sensory neurons, releasing neuropeptides like substance P and CGRP.
• These neuropeptides trigger local edema, hyperemia, and erythema, collectively known as neurogenic inflammation.
• Neurogenic inflammation is a ubiquitous process in mammals, occurring throughout the body due to widespread sensory neuron innervation.

Purpose of the Study:

• To review the physiological and pathological relevance of neurogenic inflammation.
• To explore the role of neuropeptide release from sensory nerve endings in inflammatory processes.
• To discuss potential therapeutic strategies targeting neurogenic inflammation.

Main Methods:

• Review of existing scientific literature on neurogenic inflammation and neuropeptide release.
• Analysis of studies investigating the involvement of sensory nervous systems in inflammatory responses.
• Examination of pharmacological agents and their effects on neurogenic inflammation.

Main Results:

• Neurogenic inflammation is a well-established process mediated by neuropeptides from sensory neurons.
• Numerous endogenous and exogenous substances can stimulate sensory nerve endings, causing pain and inflammation.
• Pharmacological agents, particularly vanilloid receptor modulators like capsaicin, can suppress or prevent neurogenic inflammation.

Conclusions:

• Neurogenic inflammation is a significant physiological and pathological process.
• Targeting sensory nerve pathways offers a promising therapeutic avenue for inflammatory conditions.
• Vanilloid receptor agonists and antagonists represent key targets for managing neurogenic inflammation and associated pain.
