Resistance to Streptozotocin-Induced Autoimmune Diabetes in Absence of Complement C3: Myeloid-Derived Suppressor Cells Play a Role. [PDF]
The contribution of complement to the development of autoimmune diabetes has been proposed recently. The underlying mechanisms, however, remain poorly understood.

Intracellular activation of complement C3 by tumor cells was found to suppress CD8+ T-cell responses by modulating tumor-associated macrophages. The data suggest that a combined strategy of PD-L1 blockade with C3 targeting may enhance antitumor immunity.

Complement Inactivation by Recombinant Human C3 Derivatives [PDF]
Abstract From the implications of the complement system in a large number of diseases, an urgent need for therapeutics effecting reduced complement activity in vivo has emerged. In this study we report the design of a novel class of enzymes of human origin that obliterate functional complement by a noninhibitory, catalytic mechanism ...

Complement component C3: A structural perspective and potential therapeutic implications
As the most abundant component of the complement system, C3 and its proteolytic derivatives serve essential roles in the function of all three complement pathways. Central to this is a network of protein-protein interactions made possible by the sequential proteolysis and far-reaching structural changes that accompany C3 activation.

Kidney Diseases Caused by Complement Dysregulation: Acquired, Inherited, and Still More to Come
Inherited and acquired dysregulation of the complement alternative pathway plays an important role in multiple renal diseases. In recent years, the identification of disease-causing mutations and genetic variants in complement regulatory proteins has ...

Complement C3 Produced by Macrophages Promotes Renal Fibrosis via IL-17A Secretion
Complement synthesis in cells of origin is strongly linked to the pathogenesis and progression of renal disease. Multiple studies have examined local C3 synthesis in renal disease and elucidated the contribution of local cellular sources, but the ...

The impact of the renal microenvironment on macrophage phenotypes determination can contribute to the progression or resolution of renal fibrosis. While the complement proteins affect macrophage polarization, whether complement component 3 (C3) can ...

BACKGROUND Whether the complement system is involved in the development of diabetic microvascular disease is unknown. We tested the hypothesis that high concentrations of complement C3 are associated with increased risk of diabetic retinopathy ...

Genomic organization of human complement component C3
Six overlapping clones, spanning the entire C3 gene and the 5' flanking region, were isolated from two genomic lambda libraries. Thirty exons, covering the complete beta chain and part of the alpha chain as far as the C3d region, were analyzed.
