Özet
Agomelatine is a melatonergic antidepressant that has been shown to exert beneficial effects on stress-related behavioral and neurobiological outcomes. The present study investigated its impact on cognitive functions and neurogenesis in rats given acute stress. Male and female rats (n = 10 per group) were divided into four subgroups: control, acute stress, agomelatine-treated control, and agomelatine-treated stress. Agomelatine (10 mg/kg/day) was supplied via gavage for 14 days. Behavioral assays (sucrose preference, forced swimming test, Y‑maze) and immunohistochemical analyses (DCX, Nestin, Ki-67) were conducted. Agomelatine treatment improved cognitive function in stressed rats, reduced cortisol levels, and increased markers of hippocampal neurogenesis. These data demonstrate that agomelatine mitigates acute stress-induced behavioral and neuroendocrine changes, suggesting its potential function in stress-related disease.
