TGF‐β, which is prominently expressed in MS lesions (van Horssen et al., 2006), induced a significant and consistent increase in TRPM7 gene expression, whereas exposure to TNF‐α, IFN‐γ, IL‐1α, and complement C1q did not induce mRNA expression of TRPM7 (Figure 1d). This evidence concerns the gene TGFB1 and myeloid sarcoma.
