Radiotherapy is a common treatment for brain and spinal cord tumors and also a risk factor for neuropathological changes in the brain leading to different neurological and neuropsychological disorders. Astroglial connexins are involved in brain inflammation, development of Alzheimer’s Disease (AD), depressive, epilepsy, and amyotrophic lateral sclerosis, and are affected by radiation exposure. Therefore, it is speculated that radiation-induced changes of astroglial connexins may be related to the brain neuropathology and development of neurological and neuropsychological disorders. In this paper, we review the functional expression and regulation of astroglial connexins expressed between astrocytes and different types of brain cells (including oligodendrocytes, microglia, neurons and endothelial cells). The roles of these connexins in the development of AD, depressive, epilepsy, amyotrophic lateral sclerosis and brain inflammation have also been summarized. The radiation-induced astroglial connexins changes and development of different neurological and neuropsychological disorders are then discussed. Based on currently available data, we propose that radiation-induced astroglial connexins changes may be involved in the genesis of different neurological and neuropsychological disorders which depends on the age, brain regions, and radiation doses/dose rates. The abnormal astroglial connexins may be novel therapeutic targets for the prevention of radiation-induced cognitive impairment, neurological and neuropsychological disorders.

神经和神经心理疾病和辐射暴露中的星形胶质细胞连接蛋白

放射治疗是脑和脊髓肿瘤的常见治疗方法,也是导致不同神经和神经心理疾病的大脑神经病理学变化的危险因素。星形胶质细胞连接蛋白与脑部炎症、阿尔茨海默病 (AD) 的发展、抑郁症、癫痫症和肌萎缩性侧索硬化症有关,并受辐射照射的影响。因此,推测辐射引起的星形胶质细胞连接蛋白的变化可能与脑神经病理学以及神经和神经心理疾病的发展有关。在本文中,我们回顾了星形胶质细胞与不同类型脑细胞(包括少突胶质细胞、小胶质细胞、神经元和内皮细胞)之间表达的星形胶质连接蛋白的功能表达和调控。还总结了这些连接蛋白在 AD、抑郁症、癫痫、肌萎缩侧索硬化和脑部炎症发展中的作用。然后讨论了辐射引起的星形胶质细胞连接蛋白的变化和不同神经和神经心理疾病的发展。根据目前可用的数据,我们提出辐射诱导的星形胶质细胞连接蛋白变化可能与不同神经和神经心理疾病的发生有关,这取决于年龄、大脑区域和辐射剂量/剂量率。异常的星形胶质细胞连接蛋白可能是预防辐射诱发的认知障碍、神经和神经心理疾病的新治疗靶点。然后讨论了辐射引起的星形胶质细胞连接蛋白的变化和不同神经和神经心理疾病的发展。根据目前可用的数据,我们提出辐射诱导的星形胶质细胞连接蛋白变化可能与不同神经和神经心理疾病的发生有关,这取决于年龄、大脑区域和辐射剂量/剂量率。异常的星形胶质细胞连接蛋白可能是预防辐射诱发的认知障碍、神经和神经心理疾病的新治疗靶点。然后讨论了辐射引起的星形胶质细胞连接蛋白的变化和不同神经和神经心理疾病的发展。根据目前可用的数据,我们提出辐射诱导的星形胶质细胞连接蛋白变化可能与不同神经和神经心理疾病的发生有关,这取决于年龄、大脑区域和辐射剂量/剂量率。异常的星形胶质细胞连接蛋白可能是预防辐射诱发的认知障碍、神经和神经心理疾病的新治疗靶点。我们提出辐射诱导的星形胶质细胞连接蛋白变化可能与不同神经和神经心理疾病的发生有关,这取决于年龄、大脑区域和辐射剂量/剂量率。异常的星形胶质细胞连接蛋白可能是预防辐射诱发的认知障碍、神经和神经心理疾病的新治疗靶点。我们提出辐射诱导的星形胶质细胞连接蛋白变化可能与不同神经和神经心理疾病的发生有关,这取决于年龄、大脑区域和辐射剂量/剂量率。异常的星形胶质细胞连接蛋白可能是预防辐射诱发的认知障碍、神经和神经心理疾病的新治疗靶点。
