The authors show an important role for iron in B cell proliferation via histone 3 lysine 9 (H3K9) demethylation at the cyclin E1 promoter. Using a measles vaccination murine model, they show that iron-deficient individuals have a significantly reduced antibody response to the vaccine when compared to iron-normal controls.
