| 摘要 |
The present invention discloses novel dendritic cell maturation-inducing cytokine cocktails, and methods for inducting type-1 polarized dendritic cells in serum-free conditions which enhance the desirable properties of DC1s generated in serum-supplemented cultures. The invention further discloses methods and systems using IFNgamma and other ligands of the IFNgamma receptor, in combination with IFNalpha (or other type I interferons), poly I:C, and other IFNalpha (and IFNbeta) inducers to enhance the IL-12-producing properties of dendritic cells. More specifically, the present invention discloses type-1 polarized dendritic cells that have a unique combination of a fully-mature status and an elevated, instead of "exhausted", ability to produce IL-12p70. allows for the generation of fully-mature DC1s in serum-free AIM-V medium. The invention discloses systems that use the foregoing products and methods to facilitate the clinical application of DC1-based vaccines and the identification of novel factors involved in the induction of Th1 and CTL responses by DC1.
