Treatment-resistant depression (TRD) remains a major clinical challenge, with highly variable responses to ketamine. Immune activation characterizes a subset of patients with TRD. The kynurenine pathway (KP), which integrates immunometabolic signals with glutamatergic neurotransmission, may provide candidate biomarkers to inform personalized treatment. We investigated whether KP metabolites and...
Novel antidepressive substances are challenging the explanations for the mechanisms of action of traditional psychopharmacology. What could be the shared effects of various antidepressants and in this context what role do extrapharmacological factors, such as the body and environment, play? The available literature on clinical and preclinical data for assumed combined active factors of...
Neuroinflammatory processes in depression are associated with treatment resistance to conventional antidepressants. Ketamine is an effective new therapeutic option for treatment-resistant depression (TRD). Its well-established immunomodulatory properties are hypothesized to mediate its antidepressant effect. In this context, higher levels of inflammation may predict a better treatment response....
Abstract Alcohol Use Disorder (AUD) adversely affects the lives of millions of people, but still lacks effective treatment options. Recent advancements in psychedelic research suggest psilocybin to be potentially efficacious for AUD. However, major knowledge gaps remain regarding (1) psilocybin’s general mode of action and (2) AUD-specific alterations of responsivity to psilocybin treatment in...
