A new perspective on hippocampal synaptic plasticity and post-stroke depression

Ning Sun et al. Eur J Neurosci. 2023 Aug.

Abstract

Post-stroke depression, a common complication after stroke, severely affects the recovery and quality of life of patients with stroke. Owing to its complex mechanisms, post-stroke depression treatment remains highly challenging. Hippocampal synaptic plasticity is one of the key factors leading to post-stroke depression; however, the precise molecular mechanisms remain unclear. Numerous studies have found that neurotrophic factors, protein kinases and neurotransmitters influence depressive behaviour by modulating hippocampal synaptic plasticity. This review further elaborates on the role of hippocampal synaptic plasticity in post-stroke depression by summarizing recent research and analysing possible molecular mechanisms. Evidence for the correlation between hippocampal mechanisms and post-stroke depression helps to better understand the pathological process of post-stroke depression and improve its treatment.

Keywords: Ca2+/calmodulin-dependent protein kinase II; brain-derived neurotrophic factor; connexin 43; hippocampus; post-stroke depression; synaptic plasticity.
