Mesenchymal stromal cells inhibit CD25 expression via the mTOR pathway to potentiate T-cell suppression |pdf=|usr=}}{{28230853}} gab.com Text Mesenchymal stromal cells inhibit CD25 expression via the mTOR pathway to potentiate T-cell suppression JO: Cell Death Dis http://www.kidney.de/pget.php?&tw=1&pmid=28230853 #FOAvip Mesenchymal stromal cells (MSCs) are known to suppress T-cell activation and proliferation. Several studies have reported that MSCs suppress CD25 expression in T cells. However, the molecular mechanism underlying MSC-mediated suppression of CD25 expression has not been fully examined. Here, we investigated the mTOR pathway, which is involved in CD25 expression in T cells. We showed that MSCs inhibited CD25 expression, which was restored in the presence of an inducible nitric oxide synthase (iNOS) inhibitor. Since CD25 mRNA expression was not inhibited, we focused on determining whether MSCs modulated components of the mTOR pathway in T cells. MSCs increased the phosphorylation of liver kinase B1 (LKB1) and AMP-activated protein kinase (AMPK) and decreased the phosphorylation of ribosomal protein S6 kinase 1 (S6K1) and eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1). In addition, the expression of 4E-BP1 increased dramatically in the presence of MSCs. An m7GTP pull-down assay showed increased binding of 4E-BP1 to the 5? cap-binding eukaryotic translation initiation factor 4E (eIF4E) complex in the presence of MSCs, which resulted in inhibition of mRNA translation. Treatment with 4EGI-1, a synthetic inhibitor of mRNA translation, also reduced CD25 expression in T cells. Polysome analysis confirmed decreased CD25 mRNA in the polysome-rich fraction in the presence of MSCs. Taken together, our results showed that nitric oxide, produced by MSCs, inhibits CD25 translation through regulation of the LKB1-AMPK-mTOR pathway to suppress T cells.
