Iron Limitation as an Innate Immune Defense In addition to mitigating toxicity associated with hypo- or hyperferremia, regulation of iron distribution serves as an innate immune mechanism against invading pathogens. Even in the absence of infection, several facets of human iron metabolism ensure that iron is scarcely accessible to pathogenic microorganisms. First, the majority of ironContinue reading “Limit iron intake to limit growth of invading pathogens”
