Multiomics and proteomic insights into Alzheimer's disease biology in Down syndrome
This scientific review synthesizes findings from brain, cerebrospinal fluid, and blood-based proteomic studies to characterize molecular pathways underlying Alzheimer's disease in Down syndrome, with focus on disruption of proteostasis, mitochondrial function, and immune signaling. The analysis positions Down syndrome-associated Alzheimer's disease as a network-level disorder where amyloid and tau pathology interact with immune responses, providing insights applicable to broader Alzheimer's disease biology.
