Iron-saturated transferrin did not reverse the intracellular killing or inhibition of Toxoplasma gondii, Chlamydia psittaci, or Leishmania donovani by gamma interferon-activated human macrophages. Deferoxamine, an iron chelator, also did not impair replication within unstimulated macrophages. Limiting the availability of intracellular iron is an unlikely mechanism in human macrophage activity against these three diverse pathogens.
铁饱和转铁蛋白并不能逆转γ干扰素激活的人巨噬细胞对刚地弓形虫、鹦鹉热衣原体或杜氏利什曼原虫的细胞内杀伤或抑制作用。铁螯合剂去铁胺也不会损害未受刺激的巨噬细胞内的病原体复制。限制细胞内铁的可用性不太可能是人巨噬细胞针对这三种不同病原体发挥活性的机制。
