The complement system in kidney diseases

Complement in Non-Antibody-Mediated Kidney Diseases

The complement system is part of the innate immune response that plays important roles in protecting the host from foreign pathogens. The complement components and relative fragment deposition have long been recognized to be strongly involved also in the pathogenesis of autoantibody-related kidney glomerulopathies, leading to direct glomerular injury and recruitment of infiltrating inflammation...

The complement system in renal diseases.

The complement system has long been recognized as having a role in immune glomerular disease. This review provides an update on this association, some strategies for the clinical testing of complement in disease, and a brief commentary on current research directions. Evidence of complement activation in glomerulonephritis comes from characteristic patterns of a decrease in the serum concentrati...

The complement system in liver diseases.

The complement system plays an important role in mediating both acquired and innate responses to defend against microbial infection, and in disposing immunoglobins and apoptotic cells. The liver (mainly hepatocytes) is responsible for biosynthesis of about 80-90% of plasma complement components and expresses a variety of complement receptors. Recent evidence from several studies suggests that t...

Complement related kidney diseases: Recurrence after transplantation

The recurrence of renal disease after renal transplantation is becoming one of the main causes of graft loss after kidney transplantation. This principally concerns some of the original diseases as the atypical hemolytic uremic syndrome (HUS), the membranoproliferative glomerulonephritis (MPGN), in particular the MPGN now called C3 glomerulopathy. Both this groups of renal diseases are characte...
