Insights

MicroRNAs (miRNAs) are key regulators of gene expression and neuronal plasticity, offering a novel approach to chronic pain management. Research into miRNA-based analgesics and personalized therapies shows promise for improving patient outcomes.

Area of Science:

  • Neuroscience
  • Genetics
  • Pharmacology

Background:

  • Chronic pain affects 20-25% of the global population, significantly impacting daily life and necessitating improved treatments.
  • Current analgesics offer limited relief for many chronic pain patients, highlighting the need for novel therapeutic strategies.
  • MicroRNAs (miRNAs) are emerging as crucial regulators of gene expression in the nervous system, implicated in neuronal plasticity.

Purpose of the Study:

  • To review the role of miRNAs in chronic pain mechanisms.
  • To explore the potential of miRNAs as biomarkers for patient categorization and personalized pain therapy.
  • To examine strategies for developing miRNA-based analgesics and their clinical applications.

Main Methods:

  • Systematic review of studies on chronic pain-related miRNAs in animal models and human patients.
  • Analysis of miRNA expression patterns and their correlation with pain variability.
  • Investigation of current strategies for miRNA-based therapeutic development and clinical trials.

Main Results:

  • miRNA involvement in maladaptive plasticity mechanisms underlying chronic pain is well-documented.
  • Clinical studies indicate that miRNA expression profiles may help stratify patients, enabling personalized pain management.
  • Various strategies for designing miRNA-based analgesics are under investigation.

Conclusions:

  • miRNAs represent a significant area of research for understanding and managing chronic pain.
  • miRNA-based approaches hold potential for developing targeted analgesics and personalized therapies for chronic pain.
  • Ongoing clinical trials suggest miRNAs could become a valuable therapeutic tool for chronic pain patients.

Analgesia 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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Nociception01:44

Nociception

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.

Opioid Receptors: Overview01:22

Opioid 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,...

Opioid Analgesics: Synthetic and Semisynthetic Opioids

Synthetic and semisynthetic opioids are pivotal in pain management and tackling opioid addiction. Semisynthetic opioids, including morphinans (morphine derivatives), oxycodone, oxymorphone, hydrocodone, and hydromorphone, have improved pharmacokinetic profiles compared to morphine. Additionally, heroin and 6-MAM (6-Monoacetylmorphine) show better CNS penetration than morphine due to heightened lipid solubility. Hydromorphone, a potent opioid, undergoes hepatic metabolism to form the active...
