This effect is assumed to be related to activation of the serotonin 2B receptor on heart tissue.

Yet about 95% of the serotonin in the body is made in the gut, not in the brain, says Dr. Gershon.
When used at the approved dose of 10 milligrams twice a day, Belviq does not appear to activate the serotonin 2B receptor.

Belviq works by activating the serotonin 2C receptor in the brain.

Howard was brought in to craft a chemical that zeroed in on and blocked the serotonin autoreceptors, while avoiding numerous other similar brain receptors required for healthy functioning.
The serotonin-transporter gene comes in two functional variants long and short.
Moreover, the changes seen in mouse brains are not exactly the same as those observed in SIDS babies, in whom the serotonin receptor in question, known as 1A, is, if anything, underactive.
That some populations have more of the long version of the serotonin-transporter gene has been noticed before, though the association has previously been made at a national, rather than a racial, level.
The resultant boomerang-shaped molecule was able to surgically strike the bad serotonin autoreceptors and spare the good receptors.
Laughter also raises the level of serotonin in the brain and in addition, produces endorphins.

Fenfluramine worked by increasing the amount of serotonin in the brain in a way that reduced appetite.
Like Cymbalta, Effexor works by preventing the brain from reabsorbing the neurotransmitters serotonin and norepinephrine.
One of the main factors identified in this research is low levels of the neurotransmitter serotonin.

They focused on drugs which work by increasing levels of the mood controlling chemical serotonin in the brain.
Blocking substance P triggers a molecular chain reaction that boosts levels of the neurotransmitter serotonin, apparently much more selectively than Prozac does.
The modern serotonin re-uptake inhibitors (prozac and what followed) do a good job of helping you manage better when things are very bad.
Dr. Gershon, professor of pathology and cell biology at Columbia, has been studying how the gut controls its behavior and that of other organs by investigating the neurotransmitter serotonin.
As for hot flashes and night sweats, the anti-seizure drug gabapentin or certain antidepressants in the selective serotonin reuptake inhibitor (SSRI) class may help some women, says Deborah Grady, M.
They looked at the gene which controls serotonin transporters in the brain.
Massaging the scalp raises the feel-good chemical serotonin in the brain.

So-called selective serotonin reuptake inhibitors such as Paxil, Prozac and Zoloft, gained widespread use on the theory that depressed people suffer from a deficit of the brain chemical serotonin.
Research published in 2000 by a group in Canada showed that giving omega-3 supplements to piglets doubled the levels of molecules called serotonin and dopamine in the frontal cortexes of the animals' brains.
They focused on measuring the density of a specific type of receptor that responds to the mood chemical serotonin.
Only after several weeks of treatment, researchers believe, do the sensors become desensitized to the new elevated serotonin level, allowing a patient's mood to brighten.
The stimulation came in two forms: pulses of electricity and pulses of chemicals that mimic the action of serotonin and dopamine, two molecules that transmit messages between nerve cells.
ECONOMIST: An experiment on rats brings hope to the paralysed
Also there's a physiological reason, because when an amount of sunshine enters the retina it will result in the production of serotonin, which is also produced when you take Prozac.
Because preliminary data suggest that the number of serotonin 2B receptors may be increased in patients with congestive heart failure, Belviq should be used with caution in patients with this condition.

Also known as duloxetine, the new medicine is a follow-up to Prozac that works by keeping the brain from reabsorbing serotonin, as most antidepressants do, but also by targeting the reuptake of norepinephrine, which drugs like Prozac ignore.
Fenfluramine, the "fen" in fen-phen (the "phen" is phentermine), also stimulates serotonin but in a much broader way, hitting serotonin receptors throughout the body, including a type on the outside of cells near the heart.
