Insights

Receptor tyrosine kinases (RTKs) influence alcohol addiction behaviors. Targeting RTKs like TrkB, RET, ALK, FGFR, and EGFR offers potential new treatments for alcohol use disorder (AUD).

Area of Science:

  • Neuroscience
  • Pharmacology
  • Molecular Biology

Background:

  • Receptor tyrosine kinases (RTKs) are crucial cell signaling proteins involved in vital cellular functions.
  • RTKs regulate neuronal and glial function, impacting behavior and implicated in psychiatric disorders like addiction.
  • Specific RTKs, including TrkB, RET, ALK, FGFR, and EGFR, are linked to alcohol drinking behaviors.

Purpose of the Study:

  • To review preclinical evidence on the role of five specific RTKs in modulating alcohol drinking and related behaviors.
  • To explore the potential of RTKs as therapeutic targets for alcohol use disorder (AUD).

Main Methods:

  • Literature review of preclinical studies.
  • Focus on evidence implicating TrkB, RET, ALK, FGFR, and EGFR in alcohol-related behaviors.

Main Results:

  • Preclinical data indicate that TrkB, RET, ALK, FGFR, and EGFR significantly modulate alcohol consumption and behaviors associated with alcohol addiction.
  • RTKs are validated as 'druggable' targets, with inhibitors developed primarily for cancer treatment.

Conclusions:

  • The identified RTKs represent promising targets for developing novel pharmacotherapies for alcohol use disorder (AUD).
  • Further research into RTK modulation may lead to effective treatments for AUD.

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Targets for Drug Action: Overview

Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...
