ABSTRACT Aging is the leading risk factor for Alzheimer’s Disease (AD) and many other chronic diseases, with more than 6.5 million cases of AD in the US. Regulating or slowing cellular aging, particularly in microglia and astrocytes that regulate neuroimmunity, would have a major impact on the treatment of AD, but the proteins that control cellular aging processes are poorly understood. Cellular aging has been characterized into 9 “hallmarks” or phenotypes that define aged cells. Most hallmarks are a result of cellular stress, such as DNA damage and oxidation, and are inter-related in both their causes and outcomes. The cellular aging process is linked to dramatically altered gene expression, which is largely controlled by transcription factors (TFs). Longevity studies between species also suggest that TF activity can define the rate of aging. We hypothesize that TFs can modulate cellular aging and that identifying the TFs that play a role in aging processes will enable an entirely new generation of therapeutic targets with the potential to treat, delay, and possibly even prevent AD. The discovery of TFs that can improve the lifespan of patients would have a profound impact on the prevention and treatment of AD and many other diseases.

抽象的 衰老是阿尔茨海默病 (AD) 和许多其他慢性疾病的主要危险因素，超过 美国有 650 万 AD 病例。调节或减缓细胞衰老，特别是小胶质细胞和星形胶质细胞 调节神经免疫的蛋白质将对 AD 的治疗产生重大影响，但控制神经免疫的蛋白质 人们对细胞衰老过程知之甚少。细胞衰老被分为 9 个“标志”或 定义衰老细胞的表型。大多数特征是细胞应激的结果，例如 DNA 损伤和 氧化，并且其原因和结果都是相互关联的。细胞衰老过程与 显着改变的基因表达，很大程度上是由转录因子（TF）控制的。长寿 物种间的研究还表明 TF 活性可以决定衰老速度。我们假设 TF 可以调节细胞衰老，识别在衰老过程中发挥作用的转录因子将能够 完全新一代的治疗靶点有可能治疗、延缓甚至可能预防AD。 能够延长患者寿命的转录因子的发现将对预防产生深远的影响 以及 AD 和许多其他疾病的治疗。
