Summary: Recent GWAS have found many single nucleotide polymorphisms that affect depressive disorders, suggesting that depression is a heterogeneous disorder influenced by numerous genetic variants with small effect sizes. However, there is limited understanding of the interaction between different genetic risk factors. This study used a genome-wide gene-gene interaction approach and identified a significant interaction effect between the DPF1 gene and the 5-HTTLPR gene on lifetime depression. DPF1, previously not associated with depressive disorders, is expressed exclusively in the brain and plays a major role in neuronal development and neuroplasticity.

Summary: The study aimed to investigate the association between the genotype of 5-HTTLPR and migraine combined with depression. No significant difference was found in 5-HTTLPR genotype and allele frequency between patients with migraine and depressive disorder and patients with simple migraine, indicating that 5-HTTLPR genotype may not play a role in the onset of migraine combined with depression.

Summary: This study examined the association between the 5-HTTLPR gene variant and the occurrence of pre-eclampsia. The results showed that the S/S genotype reduced the probability of developing pre-eclampsia and pre-eclampsia with severity criteria. This suggests that the 5-HTTLPR gene variant of the SLC6A4 gene modifies the risk of pre-eclampsia development.

Summary: The study identifies a novel 5-HTTLPR allele, XL28-A, in the Japanese population and suggests that it is unlikely to be associated with psychiatric disorders, despite its functional deficit. This highlights the importance of unraveling the complex genetic variations of 5-HTTLPR for further understanding its role in psychiatric disorders.

Summary: This meta-analysis examined the association between the 5-HTTLPR polymorphism and functional dyspepsia (FD). The overall analysis showed no significant association between the 5-HTTLPR polymorphism and FD, but subgroup analysis revealed a significant association with the EPS subtype of FD, while no association was observed with the PDS subtype.

Summary: The study suggests that bonnet macaques reared under stress, carrying the ?s?-allele and having smaller adolescent hippocampal volume, exhibit reduced neurogenesis in adulthood. The positive impact of ipsilateral hippocampal volume on neurogenesis levels was observed.

Summary: The Ultimatum Game has been used to measure behavioral responses to unfair distribution. Recent studies have focused on the role of the serotonin transporter gene in these responses, but most of these studies have been conducted on non-Asians without confirming whether similar results can be seen in other ethnic groups. It has also been found that behavioral responses to unfair distribution are not limited to victims themselves but also extend to third parties. This study aimed to replicate previous findings in an Asian population and explore the relationship between the serotonin transporter gene and third-party behavior towards unfair distribution.

Summary: Neuropsychiatric disorders such as major depressive disorder (MDD) involve a complex interplay of genetic and environmental factors, with the polymorphic region of the serotonin transporter (SERT) potentially playing a role in transcriptional regulation through i-motif formation.

Summary: The study investigates the impact of the serotonergic pathway on the pathogenesis and course of inflammatory bowel diseases (IBDs), and its relationship with sleep and mood disorders. The results show that patients with active IBD have higher levels of 5-HT and SERT protein expression, which are positively correlated with insomnia severity. After treatment, only 5-HT levels are decreased.

Summary: The genotype of 5-HTTLPR is associated with postoperative pain and pain threshold in gastric cancer patients, with significant differences in heat pain threshold and Numerical Rating Scale (NRS) in the 1st postoperative 24 hours between long (L/L) and short (S/S) genotype carriers.

Summary: This study used fast-scan controlled-adsorption voltammetry (FSCAV) to measure low-periodicity fluctuations in serotonin levels in mouse hippocampi. Correlation analyses revealed that these oscillations were present in vivo but not in vitro, and were not significantly different under different conditions (sex and stress paradigm). The administration of a selective serotonin reuptake inhibitor resulted in a shift in the frequency of the oscillations, suggesting regulation by transporter proteins. Additionally, the experimental parameters of FSCAV were optimized for higher temporal resolution, leading to more pronounced shifts in oscillation frequency and decreased amplitude.

Summary: Selective serotonin reuptake inhibitors (SSRIs) are less effective in treating depression in children than in adults. This may be due to the upregulation of organic cation transporter 3 (OCT3) and plasma membrane monoamine transporter (PMAT) in juveniles, leading to faster serotonin clearance and specific blocker's antidepressant-like effects.

Summary: Martinez, Liao, and colleagues investigate the interaction between variations in genes linked to serotonergic brain function and the processing of fearful stimuli. They find that certain genetic variations are associated with larger fearful MMN amplitudes in males, indicating an impact on threat processing and social cognition.

Summary: Mild hypoxia in toadfish results in increased 5-HT uptake and degradation in peripheral tissues, leading to reduced plasma 5-HT levels. The gill appears to play a major role in the clearance of 5-HT.

Summary: This article examines the important role of endocytosis in the cellular basis of depression and anxiety. It provides a detailed explanation of the endocytic regulation of 5-HT receptors and SERT, and explores how SSRIs and hallucinogenic compounds modulate serotonin signaling through endocytosis.
