Post-acute mRNA expression of key modulators of iron homeostases and monocyte-derived cytokines in peripheral blood mononuclear cells of COVID-19 patients. Relative ΔΔCT mRNA expression as compared to levels in patients with mild to moderate COVID-19 are shown. Disease severity was categorized according to the need of medical treatment: mild to moderate, outward treatment or inward treatment without respiratory support; severe to critical, inward treatment with the need for respiratory support (oxygen supply or mechanical ventilation). p values depict significant differences between severity groups as calculated with Mann–Whitney U test, error bars indicate 1 standard error; N = 109. TFR1 transferrin receptor 1, DMT1 divalent metal transporter 1, FPN1 ferroportin-1, IL6 interleukin 6, IL10 interleukin 10, TNF tumor necrosis factor, HAMP hepcidin antimicrobial peptide, n.s. not significant
