Another study also reported that accumulation of lactosylceramide (LacCer) via β-1,4-galactosyltransferase6 (B4GALT6) promoted CCL2 production in astrocyte and B4GALT6 was actually upregulated in astrocytes expressing CCL2 in MS lesions13. The gene discussed is CCL2; the disease is myeloid sarcoma.
