An interferon-stimulated genes signature including IFI27 and OAS1, together with complement levels, may reflect the immune state of patients with SLE and identify active disease. An automated ...
Schizophrenia has been linked to polymorphism in genes encoding components of the complement system, and hyperactive complement activity has been linked to immune dysfunction in schizophrenia patients ...
Involvement of lower gastrointestinal tract (LGI) occurs in 60% of patients with graft-versus-host-disease (GVHD). Complement components C3 and C5 are involved in GVHD pathogenesis. In this phase 2a ...
Levels of C4d and C4d/C4 associate with clinical and histopathological treatment response in proliferative lupus nephritis. Complement activation markers, particularly C4d and the C4d/C4 ratio, are ...
These findings suggest complement protein levels may be an important biomarker for type 1 diabetes. Disruption of the complement system appears to precede the onset of islet autoimmunity (IA), making ...
Hereditary angioedema (HAE) is diagnosed through blood tests that measure complement protein (C4) and complement inhibitor (C1-INH) levels. Low C4 levels strongly suggest HAE, especially during an ...
