A single cell RNA-seq study of healthy human kidney, identified NELL1 transcripts in loop of Henle and distal tubular cells; in the glomerulus, it appears to be expressed by podocytes without significant expression by mesangial or endothelial cells (61–63) Future studies examining if and how autoimmunity and injury affect NELL1 expression within the kidney will be informative. Here, NELL1 is linked to Autoimmunity.
