It is extremely interesting how even though hemochromatosis causes a chain of negative effects on people’s bodies, it still provides the advantage of iron-lacking macrophages, which are more effective in combating diseases. A future research potential would be finding a way that can allow normal people to have iron-lacking macrophages that kill infectious agents more efficiently without suffering from the symptoms of …show more content…
