Abstract:
Psoriasis is a chronic inflammatory skin disease, where specific immunity and/or innate immunity may be of importance in the disease pathogenesis. Psoriasis may be worsened by stress, which suggests that a neuroimmune interaction is contributing to the disease. Serotonin (5-HT) is a monoamine which besides general effects also has an impact on cell proliferation, migration and apoptosis. 5-HT exerts its effects via several receptors. 5-HT has a role in inflammation, and 5-HT receptors as well as its transporter protein have been found in psoriatic skin. 5-HT 1A receptor-positive mast cells, and 5-HT 2A receptor and serotonin reuptake transporter (SERT)-positive T lymphocytes may be targets for therapy with serotonergic drugs in psoriasis.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
