ABSTRACT Considerable literature supports the hypothesis of dysfunction in central nervous system serotonergic circuits in the pathophysiology of mood disorders, specifically major depression. Since the development of the selective serotonin (5-HT) reuptake inhibitors, a putative role for the 5-HT transporter (SERT) in the etiology of depression has been explored. The discovery of a functional SERT polymorphism has provided a novel tool to further scrutinize the role of serotonergic neurons in depression. This article reviews the burgeoning evidence of an interaction between early life stress and an SERT polymorphism on vulnerability to depression.

    ABSTRACT: Abstract Background: Asthma is a common chronic inflammatory disease of the airways in which genetic factors play a major role in its pathogenesis. High serotonin serum levels in patients with asthma suggest that serotonin is involved in the pathophysiology of the disease. Serotonin clearance is mediated by the serotonin reuptake transporter, and functional polymorphisms in this gene lead to altered serotonin reuptake efficiency. Objective: The aim of this study was to investigate the relationship between serotonin transporter gene polymorphisms and asthma. Methods: Serotonin transporter gene polymorphisms (5-HTTLPR, rs35521 and Stin2.VNTR) were assessed by PCR-based methods in 100 children with mild to moderate persistent asthma and compared with 100 healthy controls. Results: There were no significant differences in allele, genotype or haplotype frequencies between patients and controls. No association was observed between SERT gene polymorphisms after stratification of patients for sex, age, spirometry indices, family history, passive smoking behavior and concomitant allergic rhinitis. Significant differences were observed in the distribution of 5-HTTLPR alleles (P=0.025) and genotypes (P=0.021) between patients with and without atopic dermatitis. Conclusions: Despite strong evidence suggesting the role of serotonin in the pathophysiology of asthma, we found no association between serotonin transporter gene polymorphisms and mild to moderate persistent asthma. Further serotonin transporter gene analyses in patients with severe asthma may open up new horizons in the utilization of common serotonin regulators to treat asthma, based on their pharmacogenetic effects. However, serotonin may also be indirectly influenced by emotional stress during asthma attacks.

    ABSTRACT: Psychiatric disorders are often considered as simple imbalances between a limited number of cerebral neurotransmitters. In fact, it is more complicated than this “simple approach” and each psychiatric disorder constitutes network dysfunction within which several agents and factors are implicated. Thus, the therapeutical perspectives and implications are as vast and as numerous as the diversity of those network dysfunctions. Furthermore, the description of factors influencing diseases prognoses and treatment efficacy indicates new elements to consider both in therapies and drug researches.
