Interestingly, in accordance with previous studies that observed an inverse relationship between the hepcidin expression, that increases in the liver, and Dcytb and DMT1 that decrease in the duodenum in acute inflammation [48,49], we observed a significant decrease in the small intestine Dcytb mRNA mainly on day 5 of infection, suggesting repression in the iron absorption. The gene discussed is HAMP; the disease is infection.
