**Molecular Mechanism and Rationale**
The complement cascade represents a critical innate immune system that, when dysregulated in the central nervous system, drives pathological synaptic elimination in Alzheimer's disease through a well-characterized molecular pathway. The initiation begins when amyloid-β (Aβ) oligomers and fibrillar aggregates bind to pattern recognition receptors on microglial cells, including Toll-like receptor 4 (TLR4), CD36, and receptor for advanced glycation end product
**Molecular Mechanism and Rationale**
The triggering receptor expressed on myeloid cells 2 (TREM2) functions as a critical immunoreceptor that orchestrates microglial responses to neurodegeneration through a complex signaling cascade involving its adaptor protein TYROBP (also known as DAP12). TREM2 is a type I transmembrane glycoprotein expressed exclusively on microglia within the CNS, containing an extracellular immunoglobulin-like domain that recognizes damage-associated molecular patterns (
