Ketamine and electroconvulsive therapy (ECT) achieve rapid remission in treatment-resistant depression. However, their mechanisms of action—the understanding of which is essential for refining therapeutic precision—remain unclear1, 2–3. Here, using mouse models, we identify adenosine signalling as a central pathway that underlies the antidepressant effects of these interventions. Results from...
The interplay between psychedelics, such as psilocybin, lysergic acid diethylamide (LSD) and dimethyltryptamine (DMT), and sleep is an emerging area, but their impact on sleep remains relatively underexplored. This viewpoint provides a perspective on how psychedelics may alter sleep phases, dreaming, and their potential therapeutic applications for sleep disorders.
Depression, a pervasive mental health condition, has increasingly been linked to neuroinflammation, as evidenced by elevated levels of pro-inflammatory markers such as TNF-α and IL-1β observed in patients, which underscores the role of inflammation in its pathophysiology. This study investigates the differential effects of S-ketamine (S-KET) and R-ketamine (R-KET) on inflammation-induced...
