CD33 Siglec Receptor Dysfunction Alzheimer's Disease Causal Chain

🔬 Protein Info
Gene Symbolent-gene-e0e233b2
V-type Ig-like domainSialic acid-binding capability
Two C2-type Ig-like domainsMediate protein-protein interactions
Cytoplasmic ITIMContains immunoreceptor tyrosine-based inhibition motifs (YXXL/V sequences)
Intracellular signalingRecruits phosphatases (SHP-1, SHP-2) that dephosphorylate signaling molecules
Microglial specificityCD33 is expressed almost exclusively on microglia in the brain
Age-dependent increaseCD33 expression increases with normal aging
AD-specific elevationFurther upregulated in AD brains, particularly around amyloid plaques[@walker2023]
Specific subtypesCD33+ microglia form a distinct population with reduced phagocytic capacity
