Post-stroke depression (PSD), a frequent and disabling complication of stroke, has a strong impact on almost thirty percent of stroke survivors. The pathogenesis of PSD is not completely clear so far. Neuroinflammation following stroke is one of underlying mechanisms that involves in the pathophysiology of PSD and plays an important function in the development of depression and is regarded as a sign of depression. During the neuroinflammation after ischemic stroke onset, both astrocytes and microglia undergo a series of morphological and functional changes and play pro-inflammatory or anti-inflammatory effect in the pathological process of stroke. Importantly, astrocytes and microglia exert dual roles in the pathological process of PSD due to the phenotypic transformation. We summarize the latest evidence of neuroinflammation involving in PSD in this review, focus on the phenotypic transformation of microglia and astrocytes following ischemic stroke and reveal the dual roles of both microglia and astrocytes in the PSD via modulating the neuroinflammation.
中风后抑郁(PSD)是中风常见且致残的并发症,对近30%的中风幸存者有严重影响。目前PSD的发病机制尚不完全清楚。中风后的神经炎症是PSD病理生理过程的潜在机制之一,在抑郁症的发生发展中起重要作用,被视为抑郁症的一个标志。在缺血性中风发作后的神经炎症过程中,星形胶质细胞和小胶质细胞都会经历一系列形态和功能变化,并在中风的病理过程中发挥促炎或抗炎作用。重要的是,由于表型转化,星形胶质细胞和小胶质细胞在PSD的病理过程中发挥双重作用。在本综述中,我们总结了神经炎症参与PSD的最新证据,重点关注缺血性中风后小胶质细胞和星形胶质细胞的表型转化,并揭示小胶质细胞和星形胶质细胞通过调节神经炎症在PSD中的双重作用。
