Nöropeptid W, kronik stresli sıçanlarda bilişsel bozukluğu ve kaygı benzeri davranışları hafifletir

Abstract

Objective: NPW plays a regulatory role in the neuroendocrine response to stress and the activation of the HPA axis. The current study aimed to investigate the effects of peripherally administered NPW on the cognitive functions and anxiety-like behavior of rats under chronic stress conditions. Methods: Wistar albino (250-290 gr) male rats were randomly divided as control, chronic stress group, and chronic stress exposed NPW-treated (0.1 µg/kg, subcutaneously) group. Chronic stress was induced by exposing the animals to water avoidance stress (WAS) for 1 h/day for ten consecutive days. At the end of the experimental stress procedure, an object recognition test was used to evaluate cognitive functions, and a hole-board test was used to assess anxiety levels. After the experiments, blood samples were collected to measure corticosterone levels. Results: WAS significant increases in the level of corticosterone when compared with control rats (p
