Researchers found reduced serotonin release capacity in individuals with depression, suggesting a blunted serotonin system. The study used novel imaging techniques to measure serotonin levels in the brain, providing crucial insights into the pathology of depression.
A comprehensive review of research on serotonin and depression found no link between the two, contradicting long-held theories. The study suggests that antidepressants' effectiveness may be due to managing stressful life events rather than correcting chemical imbalances.
Scientists made a breakthrough in understanding the structure and function of serotonin receptors, revealing the molecular mechanism of selective coupling with G-proteins. The study provides insights into ligand recognition and could lead to rational structure-based drug design for treating diseases linked to serotonin imbalance.
Scientists have discovered the first X-ray crystallography structure of LSD bound to its target in the brain, revealing how it induces hallucinogenic effects. The study also uncovers images of a prototypical hallucinogen coupled with the entire serotonin receptor complex.
A study modelled psilocybin's interaction with the brain, explaining its therapeutic effects on depression, anxiety and addiction. The research integrated data from various imaging techniques to reveal the stimulation of serotonin receptors 5-HT2A involved in psychoactive modulation.
Researchers at Case Western Reserve University School of Medicine used high-tech microscopes to view serotonin activating its receptor for the first time. The study highlights distinct conformations of the receptor that could lead to more precise drugs targeting specific regions or functions of serotonin receptors.
The ESRF cryo-electron microscope has achieved significant results in its first year, publishing research on the 5-HT3 serotonin receptor. The study revealed the receptor's activation cycle and binding pockets, providing crucial information for developing antinausea drugs.
A team of researchers from Case Western Reserve University School of Medicine has used cryo-electron microscopy to capture the structure of full-length serotonin receptors for the first time. This breakthrough provides valuable insights into molecular binding sites that could lead to more precise drug design and targeted therapies.
A recent paper explores how protein CK2 plays a key role in treating major depressive disorder. Manipulation of CK2 in the brain decreases depressive and anxious states through the 5-HT4 receptor.
For the first time, researchers at UNC School of Medicine have discovered precisely what LSD looks like in its active state when attached to a human serotonin receptor. This breakthrough reveals that the psychoactive effects of LSD last for so long because part of the receptor folds over the drug molecule, locking it in place.
A study in the American Journal of Pathology finds that serotonin deficiency is associated with worse rheumatoid arthritis (RA) symptoms and pathology in mice. Serotonin or its agonists can reduce RA effects, suggesting a new therapeutic target for this debilitating disease.
Researchers have uncovered a significant relationship between a chemical transmitting brain signals and genetic mutations in individuals with autism spectrum disorder. Targeting a specific serotonin receptor, 5-HT2cR, can reverse social deficits in mouse models of the autism risk gene Pten.
A study published in PLOS Pathogens has identified a key player in the movement of schistosome parasites: serotonin receptors. The discovery opens up new avenues for developing targeted treatments against this parasitic flatworm, which affects millions worldwide and kills an estimated 250,000 people annually.
A research team has decoded the molecular structure of the serotonin receptor at room temperature for the first time, revealing its dynamics and giving a more realistic picture of its physiological function. This breakthrough could lead to better-designed drugs and new ways to investigate large biomolecules.
