Cocaine exposure alters N-methyl-D-aspartate receptors (NMDARs), crucial for synaptic plasticity and addiction. This review details how cocaine impacts NMDAR expression, function, and signaling, complicating addiction research.
Area of Science:
- Neuroscience
- Molecular Biology
- Pharmacology
Background:
- Addictive states involve lasting synaptic signaling modifications.
- N-methyl-D-aspartate receptors (NMDARs) are key to long-term synaptic plasticity.
- NMDAR signaling plays a role in addiction, particularly after cocaine exposure.
Purpose of the Study:
- To review cocaine-induced changes in NMDAR expression and function.
- To summarize cocaine's effects on NMDARs and associated intracellular signaling.
- To clarify the complex role of NMDARs in cocaine addiction.
Main Methods:
- Literature review of studies on cocaine and NMDARs.
- Analysis of research on NMDAR expression and function alterations.
- Examination of cocaine's impact on NMDAR-mediated signaling pathways.
Main Results:
- Cocaine exposure leads to varied changes in NMDAR expression and function.
- NMDAR regulation by cocaine is complex, depending on brain region and synapse.
- Cocaine's effects on NMDARs are influenced by behavioral history and administration mode.
Conclusions:
- Understanding cocaine's heterogeneous effects on NMDARs is critical for addiction research.
- Further investigation is needed to resolve the consensus on NMDAR involvement in addiction.
- NMDARs represent a significant target for understanding and treating addiction.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating...
Adrenergic Agonists: Indirect-Acting Agents
One mechanism involves depleting stored catecholamines by displacing them from synaptic vesicles. These agents, known as "displacers," are transported into vesicles at the expense of noradrenaline. Examples include amphetamine and tyramine, which lack a catechol moiety, resulting in prolonged action, improved oral...
