This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to characterize T cell tolerance to prostate tumor antigens and identify the role of costimulatory receptors in overcoming this tolerance. Identification of these processes will assist in the development of novel therapeutic approaches for treating prostate cancer. We use the TRAMP model, a transgenic mouse line that develops primary prostatic tumors due to expression of the SV4O T antigen (TAg) under the transcriptional control of a prostate-specific promoter. In this summary, we report that adoptive transfer of naive TAg-specific T cells into TRAMP mice results in an initial proliferative expansion followed by a clonal deletion within 5 days. Vaccination of mice with dendritic cells pulsed with the cognate antigen results in expansion in the peripheral lymphoid compartments and subsequent trafficking to the Prostate-draining lymph nodes (pDLN). However, 11 days post-vaccine, Ag-specific T cells were no longer detectable in pDLN. In contrast, a large percentage of Ag-specific T cells were still present in the prostatic tissue of vaccinated TRAMP mice, and persisted for at least 21 days. These data demonstrate that an Ag-pulsed DC vaccine may "rescue" prostate-specific T cells from peripheral tolerance in tumor-bearing mice and promote their infiltration and survival in the prostate. On going studies are testing the role of CTLA-4 blockade and CD4+ T cell help to rescue this deletion.

Book excerpt: The goal of this project is to characterize T cell tolerance to prostate tumor antigens and to identify the role of costimulatory receptors in overcoming this tolerance. Identification of these processes will assist in the development of novel therapeutic approaches for treating prostate cancer. We use the TRAMP model a transgenic mouse line that develops primary prostatic tumors due to expression of the SV40 T antigen (TAg) under the transcriptional control of a prostate-specific promoter. In this final addendum summary we report that subsequent to adoptive transfer of naive TAg-specific T cells into TRAMP mice there is rapid expansion and contraction of the tumor-specific T cells followed by accumulation of a population of T cells that persist in the prostate as tolerant and suppressive. Co-transfer of TAg-specific CD4+ T cells delays the tolerant suppressive phenotype of prostate-tumor-specific T cells. Transfer of CD4+ T cells does not reverse tolerance of previously-tolerized CD8+ cells. The suppressive nature of these CD8+ T cells was also studied and we demonstrate that suppression is at least in-part mediated by secreted factors. Further we demonstrate that trafficking od T cells to the TRAMP prostate may be mediated by chemokines. These data demonstrate the critical balance between T cell activation and tolerance and support a mechanism by which tumor growth may induce tolerance and suppressor activity in T cells previously primed to tumor-specific antigens. A greater understanding of how tolerance of these tumor specific T cells can be reversed will certainly lead to more potent anti-tumor immunotherapies.

We use the TRAMP model a transgenic mouse line that develops primary prostatic tumors due to expression of the SV4O T antigen (TAg) under the transcriptional control of a prostate-specific promoter. In this final summary we report that subsequent to adoptive transfer of na(ve TAg-specific T cells into TRAMP mice there is rapid expansion and contraction of the tumor-specific T cells followed by accumulation of a population of T cells that persist in the prostate as tolerant and suppressive. Co-transfer of TAg-specific CD4+ T cells partially rescues the tolerant suppressive phenotype of prostate-tumor-specific T cells although over time tolerance of the CD4+ T cells ensues. In contrast transfer of CD4+ T cells does not reverse tolerance of the previously-tolerized CD4+ cells. The suppressive nature of these CD4+ T cells was also studied and we present preliminary data on the characterization of these novel suppressor cells. These data demonstrate the critical balance between T cell activation and tolerance and support a mechanism by which tumor growth may induce tolerance and suppressor activity in T cells previously primed to tumor-specific antigens.

Available in PDF, EPUB and Kindle. Book excerpt: There has been major growth in understanding immune suppression mechanisms and its relationship to cancer progression and therapy. This book highlights emerging new principles of immune suppression that drive cancer, and it offers radically new ideas about how therapy can be improved by attacking these principles. Following work that firmly establishes immune escape as an essential trait of cancer, recent studies have now defined specific mechanisms of tumor immune suppression. It also demonstrates how attacking tumors with molecular targeted therapeutics or traditional chemotherapeutic drugs can produce potent anti-tumor effects in preclinical models. This book provides basic, translational, and clinical cancer researchers with an indispensable overview of immune escape as a critical trait in cancer and how applying specific combinations of immunotherapy and chemotherapy to attack this trait may radically improve the treatment of advanced disease. - Offers a synthesis of concepts that are useful to cancer immunologists and pharmacologists, who tend to work in disparate fields with little cross-communication - Drs. Prendergast and Jaffee are internationally recognized leaders in cancer biology and immunology who have created a unique synthesis of fundamental and applied concepts in this important new area of cancer research - Summarizes the latest insights into how immune escape defines an essential trait of cancer - Includes numerous illustrations, including how molecular-targeted therapeutic drugs or traditional chemotherapy can be combined with immunotherapy to improve anti-tumor efficacy and how reversing immune suppression by the tumor can cause tumor regression

Book excerpt: Melanoma is one of the most types of cancer. When melanoma is detected at an early stage, treatment is highly successful, but outcomes can be poor when the disease is advanced. There has been significant progress in our understanding of the molecular biology, genetics, and immunology of melanoma over the past decade. This has been accompanied by rapid advances in therapeutic strategies for patients with melanoma. This book provides the clinician and the researcher with a broad understanding of the molecular and cellular pathogenesis of melanoma, explores the clinical characteristics and criteria for clinical and pathological staging of the disease, and provides an overview of current and evolving treatment strategies in the adjuvant, metastatic, and preventive settings. The treatment of special populations and rare variants of melanoma that often present particular clinical challenges is also covered. Authored by international experts in melanoma biology and clinical management, this volume concisely explains how to diagnose, treat, and prevent melanoma while reviewing advances in basic science and providing an overview of innovative approaches still under development.
Download or read book Cancer Immunotherapy written by Gang Chen and published by Elsevier Inc. Chapters. This book was released on 2013-06-04 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer is managed by surgery, radiation therapy, and systemic drug therapies. Drug therapies include endocrine manipulation, single- or multi-agent chemotherapy, and monoclonal antibody therapy. Targeted small molecules that specifically capitalize on vulnerabilities that map to signaling pathways indispensible for tumor growth and progression are now also a part of the standard of cancer care. More recently, rapidly accumulating data illustrates a critical role for the immune system in the response to chemotherapy, radiation (the abscopal effect), and novel targeted cancer therapies. Integrating immune-based therapies strategically with established and novel cancer therapeutics should generate a robust antitumor effect that takes advantage of the strengths of their individual modes of action and also leverages potential immunologic synergies.
