Accumulation of amyloid beta (Aβ) peptide and hyperphosphorylated tau protein has been proposed to play roles in neural destruction which induce Alzheimer’s disease (AD) progresses, glutamate transporter type 1 (GLT-1) and Glycogen synthase kinase3β (GSK3β) may be the pathological links between Aβ and tau pathology. Schisantherin B (STB) is one bioactive of lignans isolated from Schisandra chinensis (Turcz.) Baill which has been commonly used as a traditional herbal medicine for thousands of years. This paper was designed to investigate the effects of STB on improving the cognitive function and neurodegeneration in the mouse model of Alzheimer’s disease induced by Aβ1-42, and its possible mechanism were Glutamate transporter GLT-1, tau and GSK3β. It was found that successive intracerebroventricular (ICV) administration of STB (0.15mg/kg) for 5days significantly attenuated Aβ1-42-induced learning and memory impairment as measured by the Locomotor activity test, Y-maze test and Morris water maze test. Furthermore, STB at a dose of 0.15mg/kg restored the activities of GLT-1 and GSK3β while decreasing the levels of hyperphosphorylated tau protein in the hippocampus and cerebral cortex. The results suggested that STB might protect against cognitive deficits and neurodegeneration induced by Aβ1-42 in mice by regulating the GLT-1 restoration as well as the capacity of GSK3β.

Depression is a major mood disorder. Abnormal expression of glial glutamate transporter-1 (GLT-1) is associated with depression. Schisantherin B (STB) is one bioactive of lignans isolated from Schisandra chinensis (Turcz.) Baill which has been commonly used as a traditional herbal medicine for thousands of years. This paper was designed to investigate the effects of STB on depressive mice induced by forced swimming test (FST). Additionally, we also assessed the impairment of FST on cognitive function in mice with different ages. FST and open field test (OFT) were used for assessing depressive symptoms, and Y-maze was used for evaluating cognition processes. Our study showed that STB acting as an antidepressant, which increased GLT-1 levels by promoting PI3K/AKT/mTOR pathway. Although the damage is reversible, short-term learning and memory impairment caused by FST test is more serious in the aged mice, and STB also exerts cognition improvement ability in the meanwhile. Our findings suggested that STB might be a promising therapeutic agent of depression by regulating the GLT-1 restoration as well as activating PI3K/AKT/mTOR pathway.
