Both NK activation and autoimmunity are linked to BMP signaling, e.g., via an autocrine activation pathway via BMP receptors and BMP ligands in NK cells [80,81,82], which fits our identified target genes BMP1, BMP2, BMP3, BMP7, BMP6, BMPER, BMPR1B, and, most importantly, BMPR2. This evidence concerns the gene BMP1 and Autoimmunity.
