Characterization of dendritic-like cells derived from t(9;22) acute lymphoblastic leukemia blasts.

abstract：:The co-existence of tumor specific immunity with a progressing tumor is observed in a variety of experimental systems and remains one of the major paradoxes of tumor immunology. We now report that a human melanoma cell line (SMC) expressing MHC class II was able to induce clonal anergy in a specific, MHC-restricted CD...
