Neurotransmitters

Neurotransmitters

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.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

Antidepressant Drugs: Tricyclics, SSRIs, and SNRIs

Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...

Physiology of Emotion

Physiology of Emotion

The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...

Acute Inflammation II: Local and Systemic Effects

Acute Inflammation II: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...

Summary

Serotonin, a neurotransmitter, significantly impacts immune cells by influencing their function and communication. This highlights the intricate connection between the nervous and immune systems.

Area of Science:

Neuroimmunology
Molecular Biology

Context:

Serotonin (5-HT) is increasingly recognized for its role beyond the central nervous system.
Immune cells, including antigen-presenting cells and lymphocytes, express serotonin receptors and transporters.
Key sources of serotonin modulating immunity include gut enterochromaffin cells, peripheral nerves, platelets, and mast cells.

Purpose:

To elucidate the mechanisms by which serotonin modulates immune cell function.
To explore the bidirectional communication between the nervous and immune systems mediated by serotonin.

Summary:

Immune cells uptake serotonin via specific receptors and transporters.
Dendritic cells can transfer serotonin to T lymphocytes during antigen presentation.
Macrophages and T cells possess the capacity for serotonin synthesis.

Related Experiment Videos

Serotonin influences lymphocyte mobility, proliferation, phagocytosis, and the production of chemokines and cytokines.

The diverse immunomodulatory effects of serotonin are attributed to the heterogeneity of its receptors.

Impact:

Demonstrates the critical role of serotonin in immune system regulation.
Provides evidence for the neuro-immune axis, emphasizing the interconnectedness of these systems.
Suggests potential therapeutic targets for immune-related disorders by modulating serotonin signaling.
