This finding would be in line with other works, such as a study in which the authors measured expression of BMP genes in MS lesions and found increased expression of BMP2, BMP4, BMP5, BMP7, BMPRII, and pSMAD1/5/8 in astrocytes, microglia/macrophages, and neurons [22]. Here, BMP2 is linked to myeloid sarcoma.
