Targeting cell type-specific aging signatures to restore coordinated cellular aging across brain cell types
Debate provenance: derived from debate `sess_SDA-2026-04-03-gap-seaad-v2-20260402032945` on question: What cell types are most vulnerable in Alzheimer's Disease based on SEA-AD transcriptomic data from the Allen Brain Cell Atlas? Identify mechanisms of cell-type-specific vulnerability in neurons, microglia, astrocytes, and oligodendrocytes. Focus on gene expression patterns, pathway dysre
## Molecular Mechanism
The microglial TREM2-complement axis represents a fundamental regulatory network controlling neuroinflammation and synaptic homeostasis in neurodegenerative diseases. TREM2 (Triggering Receptor Expressed on Myeloid cells 2) is a type I transmembrane glycoprotein exclusively expressed on microglia within the central nervous system, functioning as a critical immunoreceptor that orchestrates microglial activation, survival, and phagocytic responses. The extracellular immunog
