Abstract:

Depression is the root of various diseases. It is one of the most debilitating conditions globally. Antidepressant drugs are usually the first-line of depression treatment. Arctigenin (ARC), one of active ingredient of Arctium lappa L, has been found to exert neuroprotective, anti-decrepitude, and anti-inflammatory activities. Thus, the aim of this study was to investigate the potential antidepressant- and anxiolytic-like effects of ARC using acute and chronic mild stress (CMS) mice model. ICR mice model received acute stress or chronic mild stress assessed by open field test (OFT), novelty suppressed feeding (NSF), sucrose preference test (SPT), forced-swimming test (FST), and tail suspension test (TST). After the final test, blood was collected to detect the serum levels of angiogenin (ANG), thrombopoietin (TPO), and vascular endothelial growth factor (VEGF) by enzyme-linked immunosorbent assay (ELISA). The behavioral results showed that repeated ARC (10, 30 mg/kg) administration significantly relieved the antidepressant- and anxiolytic-like effects. And repeated ARC administration at the dose of 10 and 30 mg/kg could significantly block depressive- and anxiety-like behaviors caused by CMS. Finally, ELISA results showed that ARC administration increased the serum levels of angiogenin (ANG), thrombopoietin (TPO), and vascular endothelial growth factor (VEGF). Results showed that chronic ARC administration produces antidepressant- and anxiolytic-like effects, which provides direct evidence for the first time that ARC may be a novel strategy forthe treatment of depression and even stress-related disorders. The present data supports further exploration for developing ARC administration as a novel therapeutic strategy for depression and even stress-related disorders.
