Science Progress: Women are more likely to suffer from Alzheimer's disease, which is originally related to estrogen depletion!
Time of Update: 2023-02-02
In this study, they found that in postmenopausal women, the depletion of estrogen leads to excessive elevation of nitric oxide (NO) in the brain, resulting in the production of s-nitrosolate complement factor C3 (SNO-C3), which triggers the activation of innate immune cells in the brain microglia phagocytosis synapses, ultimately leading to cognitive decline in female patients [5].
