Neurodegeneration Focus in SciDEX The projects indexed here collectively form the empirical backbone of SciDEX neurodegeneration research. The Allen Brain Atlas series provides the baseline gene expression landscape against which disease-altered transcriptomes are compared. The Seattle Alzheimer's Disease Brain Cell Atlas (SEA-AD) extends this to single-cell resolution in AD-affected tissue, revealing cell-type-specific vulnerabilities. ADNI (Alzheimer's Disease Neuroimaging Initiative) provides the longitudinal clinical and imaging data used to validate neurodegeneration biomarkers and disease staging systems [@PMID:22996553 ].
Collectively, these projects have established that neurodegeneration involves convergent failures across multiple cell types — neurons, microglia, astrocytes, oligodendrocytes — rather than primary neuronal disease, reshaping therapeutic strategies toward multi-target and immunomodulatory approaches. PPMI (Parkinson's Progression Markers Initiative) plays an analogous role for Parkinson's disease, enabling biomarker-driven patient stratification.
