The solar and serotonin systems are celebrated this Solstice Day 2014 in a bit of PubMed research. Author and publisher Bryan W. Brickner highlights established and new science supporting the fact that one’s serotonin system is as important to life (and health) as the sun. Chicago, IL (PRWEB) June 21, 2014 “Tales of reducing hot flashes and insomnia?” opened political scientist Bryan W. Brickner. “No, not today’s solstice ~ serotonin is the answer.” Serotonin (5-HT,...

Schistosoma mansoni and its close relatives are parasitic flatworms that affect millions worldwide and kill an estimated 250,000 people a year. A study published on January 16 in PLOS Pathogens identifies a new part of the molecular pathway that controls parasite movement. And because coordinated movement is essential for the schistosome life cycle in its human host, this protein is a promising new drug target. "We know that many anti-parasitic drugs act on the worm's nervous system", says...

For more than a decade the research group of Brown University Professor Walter Atwood has doggedly pursued the workings of the JC polyomavirus, which causes a disease called PML that fatally degrades the central nervous system of patients with weakened immune systems. In a study published online Oct. 2 in the Journal of Virology, his team describes how it gains entry into cells: It breaks in via certain receptors of the neurotransmitter serotonin called 5-HT2 receptors. Atwood, lead author...

A multinational research team led by scientists at the National Institutes of Health has found that a genetic variant of a brain receptor molecule may contribute to violently impulsive behavior when people who carry it are under the influence of alcohol. A report of the findings, which include human genetic analyses and gene knockout studies in animals, appears in the Dec. 23 issue of Nature. "Impulsivity, or action without foresight, is a factor in many pathological behaviors including...

Findings could affect development of future depression, schizophrenia treatments Scripps Research Institute scientists have shown for the first time that the neurotransmitter serotonin uses a specialized signaling pathway to mediate biological functions that are distinct from the signaling pathways used by hallucinogenic substances. The new findings could have a profound effect on the development of new therapies for a number of disorders, including schizophrenia and depression. The study was...

University of Michigan scientists have provided the most detailed picture yet of a key receptor in the brain that influences the effectiveness of serotonin-related antidepressants, such as Prozac. The findings, which appear online Monday ahead of print in the journal Proceedings of the National Academy of Sciences, open the door to providing a more targeted treatment of depression and anxiety with fewer side effects. Depressive disorders change a person's mood, emotions and physical...

It takes weeks or months for the effect of most antidepressants to kick in, time that can feel like an eternity to those who need the drugs the most. But new research suggests that a protein called p11, previously shown to play a role in a person's susceptibility to depression, activates a serotonin receptor in the brain known for producing a rapid antidepressant response. If scientists could develop drugs to target this receptor, they might produce an effect in as little as two days. The...
