sérotonine

Sérotonine is a monoamine neurotransmitter found in the central and peripheral nervous systems of animals, including humans. It is synthesized from the amino acid tryptophan. Sérotonine plays a significant role in regulating mood, appetite, sleep, memory, and various other physiological and psychological functions. Its levels in the brain are influenced by factors such as diet, sunlight exposure, and physical activity.

Disruptions in sérotonine signaling are associated with a range of conditions, most notably depression and anxiety disorders. Many antidepressant medications, such as selective serotonin reuptake inhibitors (SSRIs), work by increasing the availability of sérotonine in the brain. However, the exact relationship between sérotonine levels and mood disorders is complex and still an active area of research.

Beyond its role in the brain, sérotonine is also produced in the gastrointestinal tract, where it influences gut motility and other digestive processes. It is also involved in blood clotting and bone metabolism. While often discussed in the context of mental health, sérotonine's functions are multifaceted and extend to numerous bodily systems. Understanding sérotonine's diverse roles is crucial for comprehending both normal physiological functioning and the mechanisms behind various diseases.
