Summary
NMDA receptors (NMDARs) are crucial for learning and memory, and their activity drives alcohol and drug addiction. Targeting NMDARs, especially GluN2B subunits, may offer new addiction treatments.
Area of Science:
- Neuroscience
- Molecular Biology
- Addiction Research
Background:
- Addiction is a significant societal issue driven by complex molecular mechanisms.
- NMDA receptors (NMDARs) are implicated in synaptic plasticity, learning, and memory formation.
Purpose of the Study:
- To review the role of NMDAR activity in promoting drug and alcohol addiction.
- To highlight the significance of GluN2B subunits and non-canonical NMDARs in addictive behaviors.
Main Methods:
- Review of existing literature on NMDARs and addiction.
- Focus on molecular mechanisms, synaptic plasticity, and calcium signaling.
- Examination of specific NMDAR subunits and cofactors.
Main Results:
- NMDARs, activated by depolarization, exhibit calcium permeability and induce long-term molecular changes.
- NMDAR-mediated plasticity can create memory traces linking drug-related stimuli to behaviors.
- GluN2B subunits are identified as potential key regulators of addictive behaviors.
Conclusions:
- NMDAR activity plays a critical role in the development and maintenance of addiction.
- Understanding NMDAR function, including non-canonical subunits, is vital for addiction research.
- Targeting specific NMDAR components may offer novel therapeutic strategies for addiction.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
1.4K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

01:27CNS Depressants: Alcohol and Nicotine
1.5K
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...

4.5K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

01:22Opioid Receptors: Overview
5.9K
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,...

01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
1.1K
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

01:21Drugs Affecting Neurotransmitter Release or Uptake
1.7K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...
