Abstract
Aging-related cognitive decline is emerging as a health concern during the aging process of the global population. Hahn and colleagues found that glial aging was particularly accelerated in white matter compared to cortical regions. Specialized neuronal populations showed region-specific changes in gene expression. Acute dietary restriction triggers a reprogramming of genes associated with the circadian clock in glial cells, whereas injections of young mouse plasma selectively reverse age-related expression patterns. The discovery of region-specific aging could enhance our understanding of the aging process and offer new possibilities for innovative treatment strategies and interventions for cognitive impairments related to aging.
期刊介绍：
JCBFM is the official journal of the International Society for Cerebral Blood Flow & Metabolism, which is committed to publishing high quality, independently peer-reviewed research and review material. JCBFM stands at the interface between basic and clinical neurovascular research, and features timely and relevant research highlighting experimental, theoretical, and clinical aspects of brain circulation, metabolism and imaging. The journal is relevant to any physician or scientist with an interest in brain function, cerebrovascular disease, cerebral vascular regulation and brain metabolism, including neurologists, neurochemists, physiologists, pharmacologists, anesthesiologists, neuroradiologists, neurosurgeons, neuropathologists and neuroscientists.
