illness and disease caused by the pathogens．The immune system is made up of non﹣specialized defences such as skin，tears and the acidic juice produced by the stomach，keeping you from the pathogens．It also has some highly specializde defences，which are different kinds of immune cells，grouped into phagocytes and lymphocytes．Phagocytes are a type of white blood cell．They are swimming around in your blood stream，always on the lookout for antigens﹣the pathogens that have entered your bodies．Whenever they see one，ther will eat it．However，some antigens are hard to find and kill．Then lymphocytes，which are also white blood cells and the main types are B cells，T helper cells and T killer cells，Will be the killers of the sncaky antigens．B cells，T helper and T killer cells work together to find and kill these antigens．B cells produce substances，called antibodies，which stick to the antigen．When that happens，it will tell the T helper cells to e over and either：1．help the B cells kill the antigen，or 2．call the phagocytes or T killer cells to move in for the kill．Once a B cell or a T cell attacks an antigen，they create cells torememberit．Thosememory cellshang out in your blood if they see the same antigen again，they quickly recognize，it so your immune system can act faster at killing it．The immune system is more powerful than you probably imagine．Scientists from the University of Pennsylvania recently took immune cells from three patients with leukemia，then genetically cheanged them intoserial Ke
