Complement System Activation In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The complement system is a critical component of the innate immune system that plays a dual role in neurodegeneration — both in normal immune surveillance and in pathological neuroinflammation. This pathway page covers the complement cascade, its activation in Alzheimer's Disease, Parkinson's Disease, ALS, and therapeutic targeting. [@veerhuis2023]
Overview
The complement system consists of over 30 proteins that function in a cascade fashion to eliminate pathogens, clear cellular debris, and modulate immune responses. In the brain, complement proteins are produced by microglia, astrocytes, and neurons, where they participate in synaptic pruning, neurodevelopment, and inflammatory responses. [@stevens2022]

Classical Pathway
Initiator: C1q binds to antibody-antigen complexes or directly to pathogens
Activation: C1r cleaves C1s, which then cleaves C4 and C2
C3 Convertase: C4b2a formed, cleaves C3 into C3a and C3b
The study of Complement System Activation In Neurodegeneration has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
