Complement deposition in the injured kidney is common, especially in glomerulonephritis. The precise role of the complement system in the mediation of tissue injury in the kidney has been defined in recent years, and this has assumed extra importance with the recent development of specific forms of therapy directed at the complement pathway. As well as the induction of cell lysis, complement ha...

The complement system is a major constituent of the innate immune system. It not only bridges innate and adaptive arms of the immune system but also links the immune system with the coagulation system. Current understanding of the role of complement has extended far beyond fighting of infections, and now encompasses maintenance of homeostasis, tissue regeneration, and pathophysiology of multipl...

The complement system is the first line of defense against foreign intruders, and deregulation of this system has been described in multiple diseases. In age-related macular degeneration (AMD), patients have higher complement activation levels compared to controls. Recently, a combination of three single nucleotide polymorphisms (SNPs) in genes of the complement system, referred to as a complot...

background: idiopathic anterior uveitis is an anterior segment inflammation in which a detailed medical history, general and ocular physical examination is not associated with any defined clinical syndrome. alterations in immune system parameters have been reported in patients with idiopathic posterior uveitis; however no data on the role of immune system in idiopathic anterior uveitis has yet ...

background: inappropriate activation or blockage of the inhibition of complement system could cause tissue damages in autoimmune diseases particularly rheumatoid arthritis (ra). defect in complement component regulation may cause damages to tissues, on the other hand, or the damaged tissue might affect the unnecessary activation of complement components.   objective: to investigate the expressi...
