    Homeostasis and metabolism of iron and other metal ions in neurodegenerative diseases by Leilei Chen, Qingqing Shen, Yingjuan Liu, Yunqi Zhang, Liping Sun, Xizhen Ma, Ning Song, Junxia Xie

    Published 2025-02-01
    “…Abstract As essential micronutrients, metal ions such as iron, manganese, copper, and zinc, are required for a wide range of physiological processes in the brain. However, an imbalance in metal ions, whether excessive or insufficient, is detrimental and can contribute to neuronal death through oxidative stress, ferroptosis, cuproptosis, cell senescence, or neuroinflammation. …”

Bix, Gregory J. Bix, Gregory J. Bix, Gregory J. Bix

    Published 2025-02-01
    “…In this review, we explore the mechanistic hypotheses of these neurological changes, which describe CNS invasion, neuroinflammation, blood-brain barrier disruption, and gut-brain axis dysregulation, along with the novel vascular disruption hypothesis that highlights endothelial dysfunction and hypoperfusion as a core underlying mechanism. …”

    Sex-specific influences of APOEε4 genotype on hippocampal neurogenesis and progenitor cells in middle-aged rats by Bonnie H. Lee, Melike Cevizci, Stephanie E. Lieblich, Liisa A. M. Galea

    Published 2025-02-01
    “…This research investigates how these two risk factors might interact to influence biomarkers of brain health at middle age using a rat model. Compared to healthy controls, male rats with hAPOEε4 genotype showed reduced neural stem cell-like cells and new adult-born brain cells and increased microglia (marker of inflammation in the brain) at middle age. …”
