Circulating antibodies against M-type phospholipase A2 receptor and thrombospondin type-1 domain-containing 7A in Chinese patients with membranous nephropathy

Background M-type phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A) have recently been identified as target antigens for patients with idiopathic membranous nephropathy (IMN). The prevalence of PLA2R and THSD7A in the serum of MN patients deserves further investigation.
