Drug targets brain circuits that drive appetite and body weight
...lease of serotonin, a neurotransmitter that relays nerve
impulses and curbs appetite, boosts this effect. Using a dose of d-FEN that reduced feeding behavior, they correlated anorexic effects with activity patterns in a network of neurons in the brain. Researchers targeted the arcuate nucleus (ARC) region...

Researchers identify brain pathway to explain how Fenfluramine causes weight loss
...te. Serotonin acts as a neurotransmitter to convey nerve
impulses in the brain, and anti-obesity drugs such as fenfluramine, as well as the popular antidepressant medications fluoxetine (Prozac) and sertraline (Zoloft) work by enhancing this effect. However, as Elmquist explains, d-FEN's popularity was re...

endings. The target tissue most often cited as the source of this activation is known as brown adipose tissue (BAT), so named for its brown appearance, which is due to the abundant mitochondria that function to expend calories and thereby burn excess...
Infection with toxoplasmososis increases the risk of being involved in a road traffic accident
...osis is characterised by the formation of cysts in nerve
