C3-Glomerulopathy Autoantibodies Mediate Distinct Effects on Complement C3- and C5-Convertases [PDF]
C3 glomerulopathy (C3G) is a severe kidney disease, which is caused by defective regulation of the alternative complement pathway. Disease pathogenesis is heterogeneous and is caused by both autoimmune and genetic factors.

A novel and rapid method to purify the human complement opsonin C3b from human plasma [PDF]
Complement opsonin C3b is at the center of the complement cascade. All complement initiation pathways converge when convertases activate C3, converting it into the anaphylatoxin C3a and the opsonin C3b, which can attach to surfaces via its freshly ...

C3 glomerulonephritis with genetically confirmed C3 deficiency in a pediatric patient: a case report [PDF]
Complement component 3 glomerulonephritis (C3GN) is a rare kidney disease characterized by complement dysregulation that results in prominent complement component 3 (C3) deposition in the kidneys. The clinical course of C3GN varies from mild hematuria to

Aurin tricarboxylic acid protects against red blood cell hemolysis in patients with paroxysmal nocturnal hemoglobinemia. [PDF]
OBJECTIVES: Paroxysmal nocturnal hemoglobinemia (PNH) is a rare but serious condition characterized by complement-mediated red blood cell (RBC) hemolysis and episodic thrombotic attack.

Induction of immune cytolysis: tumor-cell killing by complement is initiated by covalent complex of monoclonal antibody and stable C3/C5 convertase. [PDF]
The unique specificity of monoclonal antibodies (Ab) was combined with the cell-killing function of the cytolytic alternative pathway of complement. The functionally C3b-like glycoprotein of cobra venom was linked to a murine monoclonal Ab directed to a human melanoma-associated antigen by a disulfide bond, by using a heterobifunctional crosslinking ...

Adventitial Niches, Complement and Inflammation in Pulmonary Vascular Disease: Current Status and Future Directions. [PDF]
Local complement production by pulmonary artery adventitial fibroblasts, activated intracellularly by CFD and CFB and extracellularly by GZMK+ CD8 T cells, and its secretion in soluble form and within EVs promotes macrophage and T cell chemotaxis and activation.

Deregulation of Factor H by Factor H-Related Protein 1 Depends on Sialylation of Host Surfaces
To discriminate between self and non-self surfaces and facilitate immune surveillance, the complement system relies on the interplay between surface-directed activators and regulators.
