Circulating serotonin is produced in the duodenum by enterochromaffin cells, specialized endocrine cells in the epithelia lining the gut, and functions within a specialized neuroendocrine network.

But the serotonin was not coming from the enterochromaffin cells, the cells that produce serotonin in adults, but rather from the gut’s resident bacteria. When they isolated bacteria from both ...

Molecularly defined serotonin (enterochromaffin) cells of the gut lining were distinguished by single-cell expression analysis, in situ hybridization, and immunohistochemistry into 14 topographically ...

The study, published in Nature, found that special gut cells, called enterochromaffin (EC ... When activated, villus EC cells release serotonin along with another molecule called ATP, which ...

since serotonin is an important neurotransmitter in the GI tract and greater than 80% of the body's stores are located in enterochromaffin cells of the gut. [48] The exact role of serotonin in the ...

However, cytotoxic chemotherapy appears to be associated with release of serotonin from the enterochromaffin cells of the small intestine. See full labeling. Highly emetogenic chemotherapy ...
