Activation of NF-κB driven inflammatory programs in mesenchymal elements attenuates hematopoiesis in low-risk myelodysplastic syndromes

Activation of NF-κB signaling in mesenchymal cells is common in LR-MDS. Activation of NF-κB in mesenchymal cells leads to transcriptional overexpression of inflammatory factors including negative regulators of hematopoiesis. Activation of NF-κB attenuates HSPC numbers and function ex vivo.
