Mechanisms underlying early life stress and irritable bowel syndrome discovered

Mice that experienced early life stress and later developed irritable bowel syndrome had significantly higher levels of intestinal stem cells and enterochromaffin (EC). Additionally, the mice expressed elevated secretion of serotonin as a result of the increased EC cell density.

Settling the debate on serotonin’s role in sleep

Serotonin produced by the raphe is critical for sleep in both mice and zebrafish. The firing of neurons in the raphe and the release of serotonin may help the brain build up better sleep pressure. The results may explain why some sleep-related side effects of antidepressants increase serotonin in the brain.

Study reveals roots of Parkinson’s in the brain

Changes in the brain's serotonin system may occur years before Parkinson's disease symptoms begin. Serotonin alterations could be used as a biomarker for Parkinson's disease.

Serotonin linked to somatic awareness, a condition long thought to be imaginary

Somatic awareness, a condition previously believed to be of psychological origin, is connected to a common genetic variant. The mutation leads to the malfunctioning of an enzyme critical for serotonin production.

Study explains why a moody gut often accompanies depression

Mice with a genetic mutation linked to severe depression had impaired ability for neurons in the gut and brain to create serotonin. The reduction of serotonin in the gut led to a deterioration in the gut's lining, slowing the movement of contents through the GI tract and resulting in constipation. However, treatment with 5-HTP increased neurogenesis in the gut, restoring normal function.

Possible link between autism and antidepressants use during pregnancy: Mouse Study

A new study in mice reveals a possible link between the use of SSRI antidepressants during pregnancy and an increased risk of autism-like symptoms in offspring. Offspring exposed to fluoxetine (Prozac) in utero were more likely to exhibit impaired neurotransmission caused by an overactive serotonin receptor in the prefrontal cortex, an area of the brain implicated in modulating social behaviors. However, treating the mice with a compound that blocks the receptor alleviated the behavioral problems and improved working memory.

A good night’s sleep may be in sight: New 3D models of melatonin receptors shed light on sleep disorders

Researchers have created new 3D maps of two melatonin receptors. The models can be used to help develop new treatments that not only improve sleep, but may also treat a variety of other conditions from diabetes to cancer.

Fish are accumulating certain antidepressants, antibiotics and sun cream components

Antidepressants, such as the SSRI amitriptyline, antibiotics associated with developmental problems and sun cream components are contaminating water, and are being accumulated in fish. Exposure to the medications has effects on the molecular level to the fish. Researchers say this poses a problem as consumption of gilt-head bream is on the rise, and there could be a risk of the contaminants reaching humans via diet.

Research identifies genetic causes of poor sleep

An uncommon variant of the PDE11A gene impacts both quality and duration of sleep. Genetic regions linked to sleep quality are also associated with serotonin production. The study also reveals those with the same hip circumference and a higher waist circumference sleep less, although the effect is small.
