Summary
The striatum links actions to rewards, with dopamine and oxytocin signaling playing key roles. This review explores their interaction in the striatum and the influence of glial cells.
Area of Science:
- Neuroscience
- Neurochemistry
Background:
- The striatum is crucial for associating actions with rewards.
- Neural activity in the striatum is modulated by social actions and personal reward.
- Dopamine and oxytocin signaling are key factors in the striatum's reward functions.
Purpose of the Study:
- To review the interactions between dopaminergic and oxytocinergic signaling in the striatum.
- To discuss the role of striatal astrocytes and microglia in modulating this signaling crosstalk.
Main Methods:
- Literature review of existing data on dopamine and oxytocin signaling in the striatum.
- Focus on studies investigating the interplay between these neurotransmitters.
- Brief discussion of recent findings on glial cell involvement.
Main Results:
- Dopamine and oxytocin signaling are released in response to various stimuli, including social interactions, conveying reward information.
- These neurotransmitters mutually modulate each other's actions within the striatum.
- Striatal astrocytes and microglia may act as key modulators of this dopaminergic-oxytocinergic crosstalk.
Conclusions:
- The interaction between dopamine and oxytocin in the striatum is vital for processing social reward.
- Glial cells, including astrocytes and microglia, are emerging as important regulators of this neurochemical communication.

Neurotransmitters are essential chemical messengers within the nervous system, facilitating the communication between neurons. These chemical messengers, varying in function and effect, are critical for sustaining various aspects of neurological health and emotional well-being.

01:29Drugs Affecting Neurotransmitter Synthesis
2.1K
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,...

01:25Adrenergic Agonists: Indirect-Acting Agents
2.6K
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...

3.4K
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:22Opioid Receptors: Overview
4.1K
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,...
