Brief Summary
Recently, the autophagy inducing caloric restriction mimic spermidine became available. Autophagy is essential for energy and cellular homeostasis through protein catabolism and dysregulation results in compromised proteostasis, stress-coping behavior, and in excessive secretion of signaling molecules and inflammatory cytokines. Antidepressants for example effect autophagy dependent pathways to exert their beneficial effects. It can therefore be hypothesized that autophagy induction through spermidine supplementation also shows beneficial clinical effect, particularly in the field of psychiatric conditions. It would be safe, low cost and easy to implement in relay to psychotropic medication in the treatment of psychiatric patients.Therefore, the aim of the project is to analyze clinical effects of spermidine supplementation in correlation to the underlying, multi-level molecular profiling.
