In the current study we elucidate the expression of the different DS domains defined by antibodies LKN1 and GD3A12 using a panel of renal biopsies obtained from patients with acute interstitial, acute vascular and chronic renal allograft rejections, and from patients with focal segmental glomerulosclerosis (FSGS), membranous glomerulopathy (MGP) and systemic lupus erythematosus (SLE). The gene discussed is CCL15; the disease is focal segmental glomerulosclerosis.
