Immune response to an allogeneic progressively growing solid tumor.
A C57BL/6 (B6) methylcholanthrene-induced solid tumor grows progressively in BALB/c mice. The BALB/c mice fail to develop in their spleens cytotoxic lymphocytes directed against the histocompatibility (H-) antigens of the tumor. A B6 skin graft is rejected normally by mice with the progressively growing B6 tumor and skin graft rejection has no influence on the growth of the tumor. Tissue cultur...
متن کاملIndoleamine 2,3-dioxygenase and tumor-induced tolerance.
Tumors arise from normal cells of the body through genetic mutation. Although such genetic mutation often leads to the expression of abnormal antigens, the immune system fails to respond effectively to these antigens; that is, it is tolerant of these antigens. This acquired state of tolerance must be overcome for cancer immunotherapy to succeed. Indoleamine 2,3-dioxygenase (IDO) is one molecula...
متن کاملLow-Intensity Focused Ultrasound Induces Reversal of Tumor-Induced T Cell Tolerance and Prevents Immune Escape.
Immune responses against cancer cells are often hindered by immunosuppressive mechanisms that are developed in the tumor microenvironment. Induction of a hyporesponsive state in tumor Ag-specific T cells is one of the major events responsible for the inability of the adaptive immune system to mount an efficient antitumor response and frequently contributes to lessen the efficacy of immunotherap...
متن کاملMonitoring immune responses in cancer patients receiving tumor vaccines.
Clinical evaluation of therapeutic tumor vaccines has resulted in examination and comparison of the types of immune function assays required to monitor tumor antigen-stimulated T cell effector function in immunized patients. Three of the most commonly used assays include ELISPOT, tetramer assay, and cytokine flow cytometry (CFC). Discussed are the method and principles for each assay and an ass...
متن کاملPD-1/PD-L1 Interaction Maintains Allogeneic Immune Tolerance Induced by Administration of Ultraviolet B-Irradiated Immature Dendritic Cells
Our previous study demonstrated that transfusion of ultraviolet B-irradiated immature dendritic cells (UVB-iDCs) induced alloantigen-specific tolerance between two different strains of mice. Programmed death-1 (PD-1) and programmed death ligand-1 (PD-L1) have been suggested to play an important role in maintaining immune tolerance. In the present study, we seek to address whether PD-1/PD-L1 pla...
