Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a potent cytok
ine capable of inducing differentiation, proliferation, and activation of a
variety of immunologically active cell populations. In addition to its eff
ects on stimulating granulocytic hematopoiesis, it also facilitates develop
ment of both humoral and cellular mediated immunity. Accordingly, strategie
s involving the use of GM-CSF as a vaccine adjuvant have attracted consider
able attention. These strategies include the systemic administration of sol
uble GM-CSF with an immunogen, and also its use as part of gene therapy app
roaches to immunization. Because of the potency of this cytokine as an immu
ne adjuvant, particular interest has focused on its use to overcome poorly
immunogenic antigens such as those associated with intracellular infections
and cancer. This review focuses on recent advances in the use of GM-CSF as
a vaccine adjuvant. (C) 2000 Lippincott Williams & Wilkins, Inc.
