Hematoregulators

Natural host defenses against pathogens require efficient production of mature effector cells. Impairment of this function results in invasive infections in cancer patients or in other patients with suppressed immune systems such as burn or surgical patients. The hematopoietic factors, chemokines, and interleukins, which stimulate host defense mechanisms, offer new therapeutic venues. Since the late 1980s, clinical trials of CSFs
