Interferon Gamma-primed Human Bone Marrow-derived Mesenchymal Stromal Cells

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** Human bone marrow-derived mesenchymal stromal cells (MSCs) primed with interferon gamma (IFN-g), with potential immunomodulatory activity. Upon priming with IFN-g and the administration of IFN-g-primed human bone marrow-derived MSCs, IFN-g activates the IFN-g-Janus kinase (JAK)-signal transducer and activator of transcription 1 (STAT1) signaling pathway and induces indoleamine 2,3-dioxygenase (IDO) expression in MSCs. This promotes IDO activity and enhances the inhibition of T-cell proliferation mediated by MSCs. This may enhance MSC-mediated immunosuppression and prevent graft-versus-host disease (GvHD).
