2. 1. Importance of serotonin-related candidate genes for human behaviour

   Author : Jonas Melke; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; genetics; polymorphism; association study; personality; panic disorder; premenstrual dysphoria; serotonin receptor; serotonin transporter;

   Abstract : Family and twin studies have been consistent in demonstrating that genetic factors are involved in the etiology of most major psychiatric disorders, as well as in various normal personality traits. Mostly due to the efficacy of serotonin-acting drugs, such as selective serotonin reuptake inhibitors (SSRI) and tricyclic antidepressants (TCA), the neurotransmitter serotonin has been implicated in a variety of common psychiatric disorders, including depression, a spectrum of anxiety disorders, and premenstrual dysphoria; moreover, some studies have suggested that also personality is influenced by serotonin.

4. 2. Serotonin in Fear and Anxiety

   Author : S Melker Hagsäter; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; serotonin; anxiety; fear; SSRI; IBS;

   Abstract : That the neurotransmitter serotonin (5-HT) has a central role in fear and anxiety is supported by numerous experimental and clinical studies. Arguably the most illustrative example is the effect of serotonergic-acting drugs, and in particular the selective serotonin reuptake inhibitors (SSRIs), in the treatment of anxiety disorders.

5. 3. 5-HT2A : a serotonin receptor with a possible role in joint diseases

   Author : Anders Kling; Solbritt Rantapää-Dahlqvist; Carl-Olav Stiller; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 5-HT2A serotonin receptor; serotonin; rheumatoid arthritis; adverse drug reaction; HTR2A; glucocorticoids; klinisk farmakologi; Clinical Pharmacology;

   Abstract : BackgroundSerotonin (5-HT), an amino acid derivative and neurotransmitter, has for long been studied in relation to inflammation. It is an endogenous ligand for several different types of serotonin receptors. The serotonin receptor 5-HT2A has been reported to have a role in the pathophysiology of arthritis in animal experiment models. READ MORE

6. 4. Multiple neurotransmitter inputs modulate circadian clock neurons in Drosophila

   Author : Yasutaka Hamasaka; Dick Nässel; François Rouyer; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; circadian; Drosophila; neurotransmitter; G-protein coupled receptor; Neurobiology; Neurobiologi;

   Abstract : Most animals have endogenous circadian clocks, which drive daily rhythms in behavior and physiology to adapt to daily cycles of the environment. Several sets of neurons have been identified as circadian pacemakers (clocks) in the brain of Drosophila melanogaster, but the neuronal circuits and neurotransmitters signalling circadian information are poorly known.

7. 5. Influence of serotonin-related genes on behavior and body weight

   Author : Jessica Bah Rösman; Göteborgs universitet; []
   Keywords : Serotonin; Genes; anorexia nervosa; premenstrual dysforia; body weight; suicide; polymorphism; HTR2C; SLC6A4; GATA2; HTR3B;

   Abstract : Rationale: The neurotransmitter serotonin has been implicated in the regulation of normal behaviors, including food intake, and attributed importance for a variety of common psychiatric conditions, including major depression, suicidal behavior, eating disorders and premenstrual dysphoria. The purpose of these studies was to explore the possible influence of genetic variation in serotonin-related genes on a) body weight, b) binding capacity of the serotonin transporter in the brain of suicide attempters and c) a disorder for which numerous findings suggest serotonin to play a key role, i.
