Abstract Background Psychedelics such as psilocybin have demonstrated rapid and sustained antidepressant effects in humans, particularly when administered in carefully designed therapeutic environments (Borkel et al., 2024; Carhart-Harris et al., 2021). DMT and 5-MeO-DMT, distinguished by their brief duration of psychedelic effects, have also shown encouraging preliminary outcomes in depressive...

Abstract Background Recent clinical findings have highlighted the therapeutic potential of serotonergic psychedelics, including lysergic acid diethylamide (LSD), in the treatment of affective disorders. Despite these advances, the mechanisms driving their beneficial effects remain partially understood. Aims & Objectives This study sought to assess the prophylactic effects of LSD in rodent...

Major depressive disorder (MDD) is one of the most prevalent psychiatric conditions worldwide, affecting over 350 million people. Standard treatments, primarily antidepressants targeting serotonin, noradrenaline, and/or dopamine, are based on the monoamine hypothesis, which links depression to imbalances in these neurotransmitters. A sizable fraction of patients, however, does not get enough...

Abstract Background Recent clinical trials show that serotonergic psychedelics, including the prototypical hallucinogen lysergic acid diethylamide (LSD), present a great promise for treating affective disorders. While the hallucinogenic activities of LSD are commonly attributed to stimulation of 5-HT2A receptors, their role in LSD’s antidepressant response is still in debate. Interestingly, LSD...

Recent clinical trials show that serotonergic psychedelics, including the prototypical hallucinogen lysergic acid diethylamide (LSD), possess a great promise for treating affective disorders. Interestingly, LSD displays strong functional activity on 5-HT2B receptors and a modulatory role of the latter receptors in anxious and depressive-like behaviors has been reported. Using behavioral and in...

Serotonin is a neurotransmitter involved in many psychiatric diseases. In humans, a lack of 5-HT2B receptors is associated with serotonin-dependent phenotypes, including impulsivity and suicidality. A lack of 5-HT2B receptors in mice eliminates the effects of molecules that directly target serotonergic neurons including amphetamine derivative serotonin releasers, and selective serotonin...
