Specific serotonin reuptake inhibitors constitute a new class of psychotherapeutic agents that promote enhanced central serotonergic neurotransmission in animal studies. Sertraline, a member of this class, exhibits considerable potency and specificity in inhibiting serotonin neuronal reuptake in preclinical studies. Thus, it is likely to exert antidepressant activity without significant anticholinergic, cardiovascular, and sedative side effects. Other animal studies demonstrating decreases in food intake and body weight and reduction in voluntary alcohol consumption after sertraline administration suggest a potential for wider clinical application.

Background: Psilocybin therapy (PT) produces rapid and persistent antidepressant effects in major depressive disorder (MDD). However, the long-term effects of PT have never been compared with gold-standard treatments for MDD such as pharmacotherapy or psychotherapy alone or in combination.
Methods: This is a 6-month follow-up study of a phase 2, double-blind, randomised, controlled trial involving patients with moderate-to-severe MDD.

Due to the increasing prevalence of depressive and anxiety disorders in youth, a growing interest in the endocannabinoid system (ECS) as a potential alternative target point for treatment arised. This study aimed to investigate whether chronic administration of escitalopram reverses behavioral changes induced by maternal separation in male adolescent Wistar rats and explore the corresponding neurochemical changes in the ECS. The pups were separated from their dams for 360 min daily from postnatal day (PND) 2 until PND 15.

Neuropsychiatric and neurodevelopmental disorders are complex conditions that arise from a variety of interacting genetic and environmental factors. Among these factors, altered serotonergic signalling and mitochondrial dysfunction are strongly implicated, with a growing body of evidence to suggesting that serotonergic signalling is an important regulator of mitochondrial biogenesis. The serotonin transporter (SERT) functions to regulate synaptic 5-HT, and human allelic variants of the serotonin reuptake transporter-linked polymorphic region (5-HTTLPR) are associated with reduced SERT expression and increased susceptibility for developing neuropsychiatric disorders.
