Summary
Simultaneously monitoring dopamine and norepinephrine in the brain requires selective sensors. This work reviews electrochemical and optical methods, including DNA aptamers, for real-time neurotransmitter detection.
Area of Science:
- Neuroscience
- Analytical Chemistry
- Biomedical Engineering
Background:
- Simultaneous monitoring of dopamine and norepinephrine in the brain is crucial for understanding neurological processes.
- Existing sensing methods often lack the selectivity and real-time capability required for in vivo studies.
- Structural similarities between dopamine and norepinephrine pose a significant challenge for selective detection.
Purpose of the Study:
- To review and highlight advanced electrochemical and optical strategies for simultaneous real-time neurotransmitter monitoring.
- To discuss the potential of DNA aptamers as recognition elements for selective neurotransmitter sensing.
- To explore the application of field-effect transistor (FET) sensing for in vivo neurotransmitter analysis.
Main Methods:
- Review of electrochemical sensing techniques for neurotransmitter detection.
- Exploration of optical sensing strategies for simultaneous analyte measurement.
- Discussion of DNA aptamer-based recognition mechanisms for field-effect transistor sensors.
Main Results:
- Electrochemical and optical methods offer promising avenues for advancing simultaneous dopamine and norepinephrine measurements.
- DNA aptamers demonstrate potential for highly selective recognition of target neurotransmitters.
- Field-effect transistor (FET) biosensors integrated with aptamers show feasibility for in vivo applications.
Conclusions:
- Selective and simultaneous real-time monitoring of dopamine and norepinephrine is achievable with advanced sensing technologies.
- DNA aptamers represent a powerful tool for enhancing sensor selectivity in complex biological environments.
- Future research directions include the development of in vivo FET-aptamer sensors for comprehensive neurotransmitter analysis.

Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

2.4K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

2.9K
Indirect-acting adrenergic agonists potentiate the effects of endogenous catecholamines through different mechanisms without directly binding to adrenoceptors.
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...

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...

4.0K
Adrenergic agonists' structure-activity relationship (SAR) determines their selectivity and efficacy. These agonists comprise a phenylethylamine moiety with an aromatic ring and an ethylamine side chain.
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Drugs that mimic the action of endogenous catecholamines like noradrenaline and adrenaline are called adrenergic agonists or sympathomimetics. Based on their mechanism of action, sympathomimetics can be classified as direct-, indirect-, or mixed-acting sympathomimetics. Direct-acting adrenergic agonists activate adrenoceptors without affecting presynaptic neurons, making them independent of neuronal catecholamine-depleting agents like reserpine and guanethidine.
