Direct Toll-Like Receptor-Mediated Stimulation of Hematopoietic Stem and Progenitor Cells Occurs In Vivo and Promotes Differentiation Toward Macrophages

Abstract: As Toll-like receptors (TLRs) are expressed by hematopoietic stem and progenitor cells (HSPCs), they may play a role in hematopoiesis in response to pathogens during infection. We show here that TLR2, TLR4, and TLR9 agonists

“…Given the presence of TLR4 on HSCs and its role in activating myelopoiesis (39), this may further explain why female mice have a reduced inflammatory leukocyte production with diet-induced obesity and is consistent with our cfu-GM studies (Fig. 7, A and B).…”

“…Fish oil-rich diets promote hematopoiesis through the activation of MMP12 in the bone marrow (115). TLR4 activation induces HSC expansion and myelopoiesis and may be another mechanism by which metabolic endotoxemia imparts its effects on metainflammation (116)(117)(118). ATMs can generate inflammasome-dependent signals that activate bone marrow granulocyte and macrophage progenitors via IL-1β (119).…”

“…В последние годы показано, что ГСК экспрессируют TLRs, связывание TLR инициирует их вхождение в клеточный цикл, что стимулирует диф ференцировку миелоидных предшественников (Megías et al, 2012). Кроме прямого TLR стимула, в миелоидной дифференцировке принимают участие провоспалитель ные цитокины: TNF, IFN I и II, IL6 (Maltby et al, 2014).…”
