The murine serotonin syndrome – Evaluation of responses to 5-HT-enhancing drugs in NMRI mice

In humans, the ingestion of the combination of two or more serotonin (5-HT)-enhancing drugs but also of a single drug in overdose can induce serious adverse effects, which are characteristics of the serotonin syndrome (SS). In mice, acute administration of direct and indirect 5-HT agonists also leads to behavioral and autonomic responses, but in literature different responses are thought to be ...

Receptor mediation of exaggerated responses to serotonin-enhancing drugs in serotonin transporter (SERT)-deficient mice.

Administration of serotonin-enhancing drugs induces a distinctive behavioral syndrome in rodents. We previously reported that mice with a targeted disruption of the serotonin transporter (SERT) display some of these behaviors spontaneously, in the absence of drug. In the current studies, we assessed the drug-induced serotonin syndrome in SERT wildtype (+/+), heterozygous (+/-) and knockout (-/-...

Implication of 5-HT(2B) receptors in the serotonin syndrome.

The serotonin (5-HT) syndrome occurs in humans after antidepressant overdose or combination of drugs inducing a massive increase in extracellular 5-HT. Several 5-HT receptors are known to participate in this syndrome in humans and animal models. The 5-HT(2B) receptor has been proposed as a positive modulator of serotonergic activity, but whether it is involved in 5-HT syndrome has not yet been ...

Conservation of 5-HT1A receptor-mediated autoinhibition of serotonin (5-HT) neurons in mice with altered 5-HT homeostasis

Firing activity of serotonin (5-HT) neurons in the dorsal raphe nucleus (DRN) is controlled by inhibitory somatodendritic 5-HT1A autoreceptors. This autoinhibitory mechanism is implicated in the etiology of disorders of emotion regulation, such as anxiety disorders and depression, as well as in the mechanism of antidepressant action. Here, we investigated how persistent alterations in brain 5-H...

Ablation of serotonin 5-HT(2B) receptors in mice leads to abnormal cardiac structure and function.

BACKGROUND Identification of factors regulating myocardial structure and function is important to understand the pathogenesis of heart disease. Because little is known about the molecular mechanism of cardiac functions triggered by serotonin, the link between downstream signaling circuitry of its receptors and the heart physiology is of widespread interest. None of the serotonin receptor (5-HT(...
