Abstract

Neurodegenerative disorders, such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD) and spinocerebellar ataxias (SCAs), present an enormous medical, social, financial and scientific problem. Recent evidence indicates that neuronal calcium (Ca2+) signaling is abnormal in many of these disorders. Similar, but less severe, changes in neuronal Ca2+ signaling occur as a result of the normal aging process. The role of aberrant neuronal Ca2+ signaling in the pathogenesis of neurodegenerative disorders is discussed here. The potential utility of Ca2+ blockers for treatment of these disorders is also highlighted. It is reasoned that Ca2+ blockers will be most beneficial clinically when used in combination with other disease-specific therapeutic approaches.

摘要

神经退行性疾病,如阿尔茨海默病(AD)、帕金森病(PD)、肌萎缩侧索硬化症(ALS)、亨廷顿病(HD)和脊髓小脑共济失调(SCA),带来了巨大的医学、社会、经济和科学问题。最近的证据表明,在许多这类疾病中神经元钙(Ca2+)信号是异常的。由于正常衰老过程,神经元Ca2+信号也会出现类似但不太严重的变化。本文讨论了异常神经元Ca2+信号在神经退行性疾病发病机制中的作用。还强调了Ca2+阻滞剂对治疗这些疾病的潜在效用。据推断,Ca2+阻滞剂与其他针对特定疾病的治疗方法联合使用时,在临床上将最为有益。
