Phospholipase A2 receptor (PLA2R) and THSD7A stable cell line

For anti-PLA2R/TSHD7A Indirect Immunofluorescent Antibody Assay (IFA) development and related research

Primary membranous nephropathy (PMN) is a kidney-specific, autoimmune glomerular disease that presents with increased protein in the urine associated with a pathognomonic pattern of injury in glomeruli. MN is a rare disease with significant HLA Class II genetic restriction and yet with two autoantigens described, it displays a remarkably consistent immunopathology based on deposition of autoantibodies in the subepithelial side of the glomerular basement membrane (GBM), a similar clinical presentation and response to therapy.

In 2009, PLA2R was defined as the predominant autoantigen in 72% of primary membranous nephropathy (MN) cases by western blotting studies using patient serum autoantibodies [1].

THSD7A is defined as the second autoantigen in MN using a similar methodological approach but only accounts for a small amount (up to 2%) of MN cases. 

Creative Diagnostics now can provide PLA2R and THSD7A high expressed stable cell lines, which can be used in PLA2R/TSHD7A autoantibody IFA development. Anti-PLA2R/THSD7A IFA Kit is also available for research use.
