Likewise, NAC was able to prevent iron-induced M1 polarization in M0, M1, and M2 BMDMs (supplemental Figure 13), indicating that the alteration of macrophage plasticity in response to iron is mostly explained by its pro-oxidant properties. PubMed:26675351
Treatment with Hx or DFO diminished the increase of some M1 polarization markers in BMDMs following treatment with hemolytic RBCs (supplemental Figure 14). PubMed:26675351

This is the case in a mouse model of SCD, which is hallmarked by hemolysis, increased circulating Hb/heme, and low levels of Hp and Hx and shows elevated hepatic macrophage iron levels and M1 polarization. PubMed:26675351
Importantly, by scavenging free heme, Hx prevents heme-induced M1 macrophage polarization and thus avoids both TLR4 activation and ROS formation. PubMed:26675351
Our data support the idea that heme-induced phenotypic switching of macrophages toward a proinflammatory phenotype can contribute to the exacerbation of inflammation and chronic tissue injury in hemolytic disorders and that Hx therapy could alleviate these pathophysiologic consequences by preventing macrophage inflammatory activation.
