Studies are not entirely consistent, but they mostly report an increase in Akkermansiaceae and Methanobacteriaceae, and a decrease in SCFA-producing Bacteroidetes and Clostridia clusters (Palm et al., 2015
Elevation of intracellular Ca 2+ activates scramblase to ensure PS externalization, opens the Gardos channels, resulting in K + efflux and subsequent cell shrinkage, and mobilizes calpain, leading to cytoskeleton degradation and membrane microvesiculation [78]
Early AD involves iron accumulation in cortical and hippocampal areas (112), which disrupts iron homeostasis by altering key regulators: TfR1 and DMT1 decrease, while ferritin, ferroportin 1, and APP increase (113, 114)
