Nutrients, Microglia Aging, and Brain Aging.
As the life expectancy continues to increase, the cognitive decline associated with Alzheimer's disease (AD) becomes a big major issue in the world. After cellular activation upon systemic inflammation, microglia, the resident immune cells in the brain, start to release proinflammatory mediators to trigger neuroinflammation. We have found that chronic systemic inflammatory challenges induce dif...
متن کاملDystrophic microglia in the aging human brain.
We have studied microglial morphology in the human cerebral cortex of two nondemented subjects using high-resolution LN-3 immunohistochemistry. Several abnormalities in microglial cytoplasmic structure, including deramification, spheroid formation, gnarling, and fragmentation of processes, were identified. These changes were determined to be different from the morphological changes that occur d...
متن کاملHomeostatic and injury-induced microglia behavior in the aging brain
Microglia cells are essential for brain homeostasis and have essential roles in neurodegenerative diseases. Aging is the main risk factor for most neurodegenerative diseases, and age-related changes in microglia may contribute to the susceptibility of the aging brain to dysfunction and neurodegeneration. We have analyzed morphology and dynamic behavior of neocortical microglia in their physiolo...
متن کاملMicroglia-aging: roles of microglial lysosome- and mitochondria-derived reactive oxygen species in brain aging.
The accumulation of lysosome- and mitochondria-derived reactive oxygen species (ROS) are the most important causative factors for aging. Autophagic dysfunction and mitochondrial DNA damage in the central nervous system (CNS) are prominently found in microglia, the resident mononuclear phagocyte population within the CNS. The autophagic dysfunction may induce the defective turnover of mitochondr...
متن کاملNutrients for the aging eye
The incidence of age-related eye diseases is expected to rise with the aging of the population. Oxidation and inflammation are implicated in the etiology of these diseases. There is evidence that dietary antioxidants and anti-inflammatories may provide benefit in decreasing the risk of age-related eye disease. Nutrients of interest are vitamins C and E, β-carotene, zinc, lutein, zeaxanthin, and...
