Complement-coagulation crosstalk in idiopathic membranous nephropathy: The potential pathogenesis and therapeutic perspective

Abstract

Idiopathic membranous nephropathy (IMN) is a glomerular disease that is prevalent in elderly males. The pathogenesis of IMN includes abnormal autoimmunity and complement activation, both of which leading to the damage of the glomerular filtration structure. Meanwhile, due to the pathological changes in the kidney, certain coagulation-related proteins are leaked from urine, resulting in the imbalance of coagulation homeostasis. Recent studies have indicated the interaction between complement and coagulation systems, while the aberration of both is common in IMN. In this review, we summarize the subsistent and underlying pathogenesis that ensue from complement-coagulation crosstalk and present the emerging evidence in this evolving field.
