Abstract EN
Hypoxia-inducible factor (HIF) 1α is a metabolic regulator that plays an important role in immunologic responses.
Previous studies have demonstrated that HIF1α participates in the M1 polarization of macrophages.
To clarify the mechanism of HIF1α-induced polarization of M1 macrophage, myeloid-specific HIF1α overexpression (Lysm HIF1α lsl) mice were employed and the bone marrow-derived and peritoneal macrophages were isolated.
RT-PCR results revealed that HIF1α overexpression macrophage had a hyperinflammatory state characterized by the upregulation of M1 markers.
Cellular bioenergetics analysis showed lower cellular oxygen consumption rates in the Lysm HIF1α lsl mice.
Metabolomics studies showed that HIF1α overexpression led to increased glycolysis and pentose phosphate pathway intermediates.
Further results revealed that macrophage M1 polarization, induced by HIF1α overexpression, was via upregulating the mRNA expression of the genes related to the glycolysis metabolism.
Our results indicate that HIF1α promoted macrophage glycolysis metabolism, which induced M1 polarization in mice.
