There are three general reasons for establishing buffer zones: to provide sanctuary, to provide a neutral area that allows for supervision where contending claims exist (in order to, potentially, facilitate cooperation), and to simply reduce tensions through separation of disputants.
Iron and immunity are closely linked: firstly by the fact that many of the genes/proteins involved in iron homoeostasis play a vital role in controlling iron fluxes such that bacteria are prevented from utilising iron for growth; secondly, cells of the innate immune system, monocytes, macrophages, microglia and lymphocytes, are able to combat bacterial insults by carefully controlling their iron fluxes, which are mediated by hepcidin and ferroportin.
The idea of boosting your immunity is enticing, but the ability to do so has proved elusive for several reasons. The immune system is precisely that â a system, not a single entity. To function well, it requires balance and harmony. There is still much that researchers don't know about the intricacies and interconnectedness of the immune response.
