1. Research Background and Academic Significance Alzheimer’s Disease (AD) is the most common form of dementia worldwide, accounting for about 60–80% of all dementia cases. The primary affected population is individuals over 65 years old, with characteristic pathological features including the deposition of amyloid-β plaques, neurofibrillary tangles...

I. Research Background and Scientific Question Alzheimer’s disease (AD) is the most common neurodegenerative disease worldwide, with pathological features mainly including neuronal loss, neurofibrillary tangles, and senile plaques (mainly formed by amyloid-β [Aβ] deposition). According to statistics, the number of AD patients continues to rise each...

Academic Background The homeostasis of the central nervous system (CNS) relies on two key types of macrophages: microglia and border-associated macrophages (BAMs). Traditionally, microglia are believed to originate from the embryonic yolk sac and possess lifelong self-renewal capabilities, while bone marrow (BM)-derived monocytes in adults cannot r...

As the global aging problem intensifies, the incidence of neurodegenerative diseases (such as Alzheimer’s Disease, AD) is increasing year by year. Brain aging (Brain Aging, BA) is one of the significant risk factors for neurodegenerative diseases, but it does not completely align with chronological age (Chronological Age, CA). Traditional methods f...

Effects of Exogenous β-Hydroxybutyrate on BDNF Signaling, Cognition, and Amyloid Precursor Protein Processing in Humans with Type 2 Diabetes and Insulin-Resistant Rodents Academic Background Patients with type 2 diabetes (T2D) have a significantly increased risk of developing neurodegenerative diseases, such as Alzheimer’s disease (AD), later in li...
