Mengke's comments:good introduction of iron about its immune function,easy to understand and straightforward. I am not sure you want to talk about the general ideas of iron's immune function or want to focus on some specific immune cells,I think the existing iron page doesn't have either kind of contents. If you just want to do general speaking, like Diana said, you might need summering of this general idea. If you want to do more specific, some details might be added.
