SLC11A1 was initially reported to fight several types of pathogens, and some studies have shown that SLC11A1 plays a role in innate immunity, autoimmune diseases, and infection (Stewart et al., 2010; Li et al., 2011; Neves et al., 2011; Cunrath and Bumann, 2019). Here, SLC11A1 is linked to autoimmune disease.
