[music] aplastic anemia occurs when the body'simmune system becomes confused and begins to attack cells thatperform critical functions. the cells affected in this condition arethe red blood cells, white blood cells, andplatelets. red blood cells are needed because theycarry life-giving oxygen to the tissues of thebody. platelets are important because they workto promote blood clotting. lymphocytes are white blood cells that actas
the first line of defense against tumorsand viruses. neutrophils are another type that works toprevent infection and disease. the low counts of red blood cells, whiteblood cells and platelets are indicators that aplasticanemia has set in. this important collection of cellsoriginates inside human bone marrow. they start life as stem cells that maturewithin the bones before passing out into the bloodstream. when suffering from an autoimmunedisorder, such as aplastic anemia, lymphocytesbecome
confused and attack the stem cells beingcreated in the bone marrow. a promising treatment for this condition requires high doses of cyclophosphamide,or hicy, an agent that eradicates the immunesystem, causing it to reboot like a computer. once rebooted, the lymphocytes no longerattack the stem cells.
