Descrizione generale
Native, human C1 complement component. C1 is the first component of the classical complement pathway. It is a calcium dependent complex of C1q, C1r, and C1s subcomponents which are present in the C1 complex at molar ratios of 1:2:2 respectively. Binding of C1 to classical pathway activators results in the conversion of the proenzyme C1s subcomponent to an active C1s enzyme. C1s enzyme cleaves both C4 and C2, resulting in formation of the C3 cleaving enzyme, C4b, C2a, of the classical complement pathway. C1 concentration is based on functional activity measurements relative to a normal serum standard pool.

Elements of the immune system particularly that of innate immunity, play important roles beyond their traditional tasks in host defense, including manifold roles in the nervous system. Complement-mediated synaptic pruning is essential in the developing and healthy functioning brain and

In infection, complement C1q recognizes pathogen-congregated antibodies and elicits complement activation. Among endogenous ligands, C1q binds to DNA and apoptotic cells, but whether C1q binds to nuclear DNA in apoptotic cells remains to be investigated. With UV irradiation-induced apoptosis, C1q

Anti-nuclear autoantibodies, which frequently target the nucleoli, are pathogenic hallmarks of systemic lupus erythematosus (SLE). Although the causes of these Abs remain broad and ill-defined, a genetic deficiency in C1 complex (C1qC1r2C1s2) or C4 is able to induce these Abs.

Alzheimer's Disease (AD) is the leading cause of dementia in the elderly. In healthy individuals, amyloid precursor protein (APP) is cleaved by α-secretase, generating soluble α-amyloid precursor protein (sAPPα), which contributes neuroprotective functions in the neuronal environment. In contrast, in
