Alzheimer's disease (AD) lacks protein biomarkers reflective of its diverse underlying pathophysiology, hindering diagnostic and therapeutic advancements. Here, we used integrative proteomics to identify cerebrospinal fluid (CSF) representing a wide spectrum AD pathophysiology. Multiplex mass spectrometry identified ~3500 ~12,000 proteins in CSF brain, respectively. Network analysis the brain proteome resolved 44 biologically modules, 15 which overlapped with proteome. markers these...

Abstract The locus coeruleus is the initial site of Alzheimer’s disease neuropathology, with hyperphosphorylated Tau appearing in early adulthood followed by neurodegeneration dementia. Locus dysfunction contributes to pathobiology experimental models, which can be rescued increasing norepinephrine transmission. To test augmentation as a potential disease-modifying therapy, we performed biomarker-driven phase II trial atomoxetine, clinically-approved transporter inhibitor, subjects mild...

Cognitive impairment in the elderly features complex molecular pathophysiology extending beyond hallmark pathologies of traditional disease classification. Molecular subtyping using large-scale -omic strategies can help resolve this biological heterogeneity. Using quantitative mass spectrometry, we measured ∼8000 proteins across >600 dorsolateral prefrontal cortex tissues with clinical diagnoses no cognitive (NCI), mild (MCI), and Alzheimer's (AD) dementia. Unbiased classification MCI AD...

Previous systems-based proteomic approaches have characterized alterations in protein co-expression networks of unfractionated asymptomatic (AsymAD) and symptomatic Alzheimer’s disease (AD) brains. However, it remains unclear how sample fractionation sub-proteomic analysis influences the organization these their relationship to clinicopathological traits disease. In this proof-of-concept study, we performed a membrane-enriched post-mortem brain samples from pathology-free control, AsymAD, AD...

Abstract Alzheimer’s disease (AD) features a complex web of pathological processes beyond amyloid accumulation and tau-mediated neuronal death. To meaningfully advance AD therapeutics, there is an urgent need for novel biomarkers that comprehensively reflect these mechanisms.
