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.
Your immune system protects you from the disease by fighting off the invading germs. How does the immune system work? Your immune system is always on patrol in your body. When it comes across an invading germ, it attacks that germ. This is called an immune response. Hereâs how an immune response works: Your immune system sounds the alarm so your body knows thereâs an infection. It begins releasing antibodies to fight the germ â think of antibodies as soldiers designed to fight off the specific germ you have. This process can take a few days. The antibodies work to attack, weaken, and destroy the germ. Afterwards, your immune system remembers the germ.
