The Effects of Serotonin in Immune Cells
TLDR
Serotonin can also suppress the release of tumor necrosis factor-α and interleukin-1β by activating serotonin receptors, and neutrophil recruitment and T-cell activation can both be mediated by serotonin.Abstract:
Serotonin (5-Hydroxytryptamine, 5-HT) plays an important role in many organs as a peripheral hormone. Most of the body's serotonin is circulating in the bloodstream, transported by blood platelets and is released upon activation. The functions of serotonin are mediated by members of the 7 known mammalian serotonin receptor subtype classes (15 known subtypes), the serotonin transporter (SERT) and by covalent binding of serotonin to different effector proteins. Almost all immune cells express at least one serotonin component. In recent years, a number of immunoregulatory functions have been ascribed to serotonin. In monocytes/macrophages for example serotonin modulates cytokine secretion. Serotonin can also suppress the release of TNF-α and IL-1β by activating serotonin receptors. Furthermore, neutrophil recruitment and T-Cell activation can both be mediated by serotonin. These are only a few of the known immunomodulatory roles of serotonin that we will review here.read more

TL;DR: It is argued that while depression and aggression represent two fundamentally different behavioral and physiological responses to social stress, it is possible that some overlapped, as well as distinct, pattern of immune signaling may underlie both of them.

Association of Anxiety-Related Traits with a Polymorphism in the Serotonin Transporter Gene Regulatory Region

TL;DR: The short variant of the polymorphism reduces the transcriptional efficiency of the 5-HTT gene promoter, resulting in decreased 5HTT expression and 5HT uptake in lymphoblasts as discussed by the authors, which is the site of action of widely used uptake-inhibiting antidepressant and antianxiety drugs.

TL;DR: The results should facilitate the development of therapeutically useful inhibitors of TNF-α release, and they indicate that an important function of adamalysins may be to shed cell-surface proteins.

TL;DR: There are two serotonin systems in vertebrates, independently regulated and with distinct functions, and these findings clarify puzzling data, which have been collected over the last decades about partially purified TPH proteins with different characteristics and justify a new concept of the serotonin system.
