Available in PDF, EPUB and Kindle. Book excerpt: The cytokine milieu in the tumor microenvironment plays a key role in modulating the immune response either in favor of or against tumorigenesis. For many tumors, this complex network of cytokine and immune interactions represent a formidable means of escape from immune surveillance. These cytokine networks are particularly important in pancreatic ductal adenocarcinoma (PDA), where a prominent infiltration of immunosuppressive immune populations could be found. Myeloid-derived suppressor cells (MDSCs) have previously been shown to be potent suppressors of anti-tumor immunity in PDA, but the cytokine networks regulating their recruitment to the tumor microenvironment remain incompletely understood. Here, I found that CXCR2 ligand expression is specifically correlated with enrichment of the granulocytic subset of MDSCs (G-MDSCs) in human PDAs. Using a genetically engineered mouse model of PDA, I showed that CXCR2 is required for G-MDSC trafficking to the tumor microenvironment, but not necessary for their systemic differentiation and expansion. The specific lack of G-MDSCs in the tumor microenvironment led to a T cell-dependent inhibition of tumor growth. Expression of CXCR2 ligands in PDA tumor cells can be potently induced by NF-?B activation. These findings describe a cytokine network in PDA where inflammatory signals in the tumor microenvironment drive the expression of CXCR2 ligands and the recruitment of immunosuppressive G-MDSCs. To discover other potentially important cytokine networks, I developed a novel analysis pipeline to reconstruct and compare cytokine networks from whole tumor gene expression data. Using expression of cytolytic genes as a gauge for anti-tumor immune activity, I found that PDA patients with high cytolytic activity have a slight survival advantage compared to those with lower activity. While macrophages were the most influential in tumors with low cytolytic activity, tumors with high cytolytic activity were characterized by increased activity of NK cells, recruitment of B cells, and increased importance of CD8 T cells, CD4 T helper cells, and B cells, among others. I further highlighted the cytokines that might be associated with these immune populations. Therefore, my analysis identified potentially important components of the cytokine network associated with high and low cytolytic activity. Collectively, the work in this thesis suggests that cytokine networks are crucial for maintaining an immunosuppressive microenvironment in cancer. Furthermore, disrupting key components of these networks can tip the balance in favor of cancer immunosurveillance.

Download or read book The Cytokine Network in Colorectal Cancer Implications for New Treatment Strategies written by Heidi Braumüller and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Colorectal cancer (CRC) is one of the most frequent tumor entities worldwide with only limited therapeutic options. CRC is not only a genetic disease with several mutations in specific oncogenes and/or tumor suppressor genes such as APC, KRAS, PIC3CA, BRAF, SMAD4 or TP53 but also a multifactorial disease including environmental factors. Cancer cells communicate with their environment mostly via soluble factors such as cytokines, chemokines or growth factors to generate a favorable tumor microenvironment (TME). The TME, a heterogeneous population of differentiated and progenitor cells, plays a critical role in regulating tumor development, growth, invasion, metastasis and therapy resistance. In this context, cytokines from cancer cells and cells of the TME influence each other, eliciting an inflammatory milieu that can either enhance or suppress tumor growth and metastasis. Additionally, several lines of evidence exist that the composition of the microbiota regulates inflammatory processes, controlled by cytokine secretion, that play a role in carcinogenesis and tumor progression. In this review, we discuss the cytokine networks between cancer cells and the TME and microbiome in colorectal cancer and the related treatment strategies, with the goal to discuss cytokine-mediated strategies that could overcome the common therapeutic resistance of CRC tumors
Download or read book Cancer Immunotherapy written by Sandra Demaria and published by Elsevier Inc. Chapters. This book was released on 2013-06-04 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tumors that become clinically apparent have invariably developed ways to escape immune control. The mechanisms of escape are multiple and diverse and do not necessarily require the loss by tumor cells of expression of antigens recognized by the immune system. More commonly, tumor-specific T cells are rendered dysfunctional by a number of soluble and cell surface-bound molecules that are produced or modified by the action of cancer cells or suppressive and regulatory immune cells recruited to the tumor. Overall, the obstacles that prevent tumor rejection are active at several levels, affecting T-cell priming, functional differentiation, recruitment to the tumor, survival and effectors’ function inside the tumor. The multifaceted nature of these immunosuppressive networks represents a formidable obstacle to the success of immunotherapy. Nevertheless, the recent achievements of therapeutics targeting key checkpoint receptors highlight the great potential of strategies that are based on selective disruption of immunosuppressive networks.

Available in PDF, EPUB and Kindle. Book excerpt: Cytokines, a broad class of proteins, have a role in fighting infection and in mounting an immune response; in mediating cell differentiation and embryogenesis; in promoting cell growth; and in inhibiting growth or causing cell death. Recent advances in cell culture, monoclonal antibodies and recombinant DNA technology have made it possible to isolate these proteins and to obtain sufficient quantities to conduct clinical studies as well as laboratory experiments. Thus, the foundations have been laid for a new form of cancer therapy and for understanding how abnormalities in the cytokine network could contribute to the process of malignancy. Up-to-date and comprehensive, this book brings together current research and discusses it in the context of its present and potential clinical application. The book is intended for cancer researchers, clinical oncologists, and those involved in the pharmaceutical and biological product industries.
Download or read book Advances in Tumor Immunology and Immunotherapy written by Joseph D. Rosenblatt and published by Springer Science & Business Media. This book was released on 2013-10-25 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in understanding of fundamental immunology have created new insights into the dynamic interactions between tumors and the immune system. This includes new understanding of T- and B-cell interaction, immune inhibitory mechanisms including the biology of T regulatory cells, myeloid suppressor cells, and dendritic cell subsets. Enhanced understanding of mechanisms underlying T-cell anergy such as arginine deprivation, immunosuppressive cytokines, defective innate and interferon response pathways, and NKG2D downregulation have all provided new insight into suppression of anti-tumor immunity and tumor evasion. In addition to emerging understanding of tumor evasion, new immune targets such as CTLA4 blockade, NK stimulatory receptors, manipulation of the antigen processing and presentation, cytokine and costimulatory responses all provide new possibilities for enhancing anti-tumor immunity even in tumors previously felt to be resistant to immune attack. Several of these strategies have already been realized in the clinic. The volume will explore evolving paradigms in antigen presentation, dendritic cell biology, the innate response and immunosuppressive mechanisms, and emerging strategies for manipulation of the immune system for therapeutic benefit that have realized success in neuroblastoma, leukemia, melanoma, lung cancer, and allogeneic transplantation. Early successes as well as failures will be highlighted to provide a snapshot of the state of clinical immunotherapy with an eye to future possibilities such as combination therapies, adoptive T-cell transfer, and the retargeting of immune cells via T-cell receptor engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Delivery Technologies for Immuno-Oncology: Volume 1: Delivery Strategies and Engineering Technologies in Cancer Immunotherapy examines the challenges of delivering immuno-oncology therapies. Immuno-oncology (IO) is a growing field of medicine at the interface of immunology and cancer biology leading to development of novel therapeutic approaches, such as chimeric antigen receptor T-cell (CAR-T) and immune checkpoint blockade antibodies, that are clinically approved approaches for cancer therapy. Although currently approved IO approaches have shown tremendous promise for select types of cancers, broad application of IO strategies could even further improve the clinical success, especially for diseases such as pancreatic cancer, brain tumors where the success of IO so far has been limited. Nanotechnology-based targeted delivery strategies could improve the delivery efficiency of IO agents as well as provide additional avenues for novel therapeutic and vaccination strategies. Additionally, a number of locally-administered immunogenic scaffolds and therapeutic strategies, such as the use of STING agonist, could benefit from rationally designed biomaterials and delivery approaches. Delivery Technologies for Immuno-Oncology: Volume 1: Delivery Strategies and Engineering Technologies in Cancer Immunotherapy creates a comprehensive treaty that engages the scientific and medical community who are involved in the challenges of immunology, cancer biology, and therapeutics with possible solutions from the nanotechnology and drug delivery side. Comprehensive treaty covering all aspects of immuno-oncology (IO) Novel strategies for delivery of IO therapeutics and vaccines Forecasting on the future of nanotechnology and drug delivery for IO

Download or read book The Link Between Inflammation and Cancer written by Angus G. Dalgleish and published by Springer Science & Business Media. This book was released on 2006-03-05 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: A link between inflammation and cancer has been established many years ago, yet it is only recently that the potential significance of this connection has become apparent. Although several examples of chronic inflammatory conditions, often induced by persistent irritation and/or infection, developing into cancer have been known for some time, there has been a notable resistance to contemplate the possibility that this association may apply in a causative way to other cancers. Examples for such progression from chronic inflammation to cancer are colon carcinoma developing with increased frequency in patients with ulcerative colitis, and the increased incidence of bladder cancer in patients suffering from chronic Schistosoma infection. Inflammation and cancer have been recognized to be linked in another context for many years, i.e., with regards to pathologies resembling chronic lacerations or 'wounds that do not heal.' More recently, the immunology of wound healing has given us clues as to the mechanistic link between inflammation and cancer, in as much as wounds and chronic inflammation turn off local cell-mediated immune responses and switch on growth factor release as well the growth of new blood vessels - angiogenesis. Both of these are features of most types of tumours, which suggest that tumours may require an immunologically shielded milieu and a growth factor-rich environment.
