To achieve this, they specifically developed imaging tools to track this molecule in mice. "It is very difficult to measure the variation of serotonin in the brain. Thanks to a biosensor developed ...

The physiology of serotonin is complex and involves synthesis, transport, reuptake and receptor activation 6. Circulating serotonin is produced in the duodenum by enterochromaffin cells ...

Not all the tryptophan we consume enters the brain and is converted into serotonin. “So, the more tryptophan in the diet, the more likely any molecule is to get across the blood brain barrier ...

While a gradual loss in muscle strength is a natural part of aging, for many older adults it's more than just feeling a little weaker. Sarcopenia -- a condition affecting nearly half of adults over 80 ...

The villus EC cells can release high levels of the neurotransmitter serotonin, and a molecular fuel called ATP, which triggers the pathways that deliver pain signals to the brain. "Villus EC cells act ...

Their recent study suggests that a small molecule drug that targets a specific serotonin receptor could become the first neurotherapeutic treatment for sarcopenia — offering hope for older adults ...
