Download or read book Activated Effector T Cells Co expressing Multiple Inhibitory Receptors are Enriched in the Tumor Immune Microenvironment of HGSOC Expressing High and Uniform WT 1 Antigen written by Massimo Candiani and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Background. In HGSOC, the association between tumor-infiltrating lymphocytes (TILs) and survival suggests a role for T cell immune surveillance. Despite this, initial attempts with PD1 checkpoint blockade and adoptive T-cell therapy (ACT) had limited efficacy. This highlights the need to characterize the phenotype of TILs and to find new potential tumor-specific antigens. WT-1 expression showed a prognostic significance in HGSOC, making it an interesting target. We evaluated the expression of WT-1 in HGSOC samples and characterized the pattern of inhibitory receptors (IRs) in TILs to identify immunosuppressive pathways.Methods. Peripheral blood (PB), tumor and ascites were retrieved from HGSOC patients admitted for primary surgery. WT-1 expression and immune infiltrate were characterized on 34 specimens by immunohistochemistry (IHC) for lineage markers and inhibitory molecules. T cells isolated from tumor, ascites and PB of 14 patients were also characterized by flow cytometry for the expression of lineage and memory markers (CD3, CD4, CD8, CD45RA, CD62L, CD95), inhibitory molecules (PD1, CTLA-4, LAG-3, TIGIT, TIM-3, 2B4, GITR, KLRG1, CD39, CD160) and the activation marker CD137.Results. WT1 was almost uniformly expressed, with 76% of cases showing high WT1 expression in the majority of tumor cells. The extend and composition of immune infiltration was heterogeneous: 6% of cases were immune desert; all other cases displayed a wide range of immune cell density, dominated by T lymphocytes and macrophages. Intratumoral T cells (ITTCs), mainly CD8, were present in 88.2% of samples. PD-1, LAG-3 and TIM-3 were expressed by 61.9%, 61.7% and 61.7% of ITTCs. PD-L1 was expressed by neoplastic cells and immune cells in 40% and 82.3% of samples.Flow cytometry confirmed the co-expression of several IRs by TILs. Compared with corresponding PB and ascites, TILs were enriched in effector memory lymphocytes and in cells co-expressing PD-1, CD39 and CD137.Conclusions. WT-1 is a potential target for ACT in HGSOC, which is infiltrated by antigen-experienced T lymphocytes displaying features of activation and partial exhaustion.

Download or read book Advances in Cancer Immunotherapy written by Jasmine Johnson and published by Murphy & Moore Publishing. This book was released on 2021-11-16 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stimulation of the immune system through artificial means for the treatment of cancer is known as cancer immunotherapy. It boosts the ability of the immune system to fight cancer cells. It is a subspecialty within oncology. The antibody proteins belonging to the immune system are able to detect the tumor antigens and bind with them. Immunotherapy can be broadly divided into two types, namely, passive immunotherapy and active immunotherapy. The tumor cells are specifically targeted through the immune system in active immunotherapy. Within passive immunotherapy, the cancer cells are not directly attacked by the immunotherapy, but the ability of the immune system to attack cancer cells is enhanced. This book includes some of the vital pieces of work being conducted across the world, on various topics related to cancer immunotherapy. Also included herein is a detailed explanation of the various concepts and applications of this branch of therapy. This book includes contributions of experts and scientists which will provide innovative insights into this field.

Download or read book Novel Research about Biomechanics and Biomaterials Used in Hip Knee and Related Joints written by J. Philippe Kretzer and published by MDPI. This book was released on 2021-08-18 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Joint replacement is a very successful medical treatment. However, the survivorship of hip, knee, shoulder, and other implants is limited. The degradation of materials and the immune response against degradation products or an altered tissue loading condition as well as infections remain key factors of their failure. Current research in biomechanics and biomaterials is trying to overcome these existing limitations. This includes new implant designs and materials, bearings concepts and tribology, kinematical concepts, surgical techniques, and anti-inflammatory and infection prevention strategies. A careful evaluation of new materials and concepts is required in order to fully assess the strengths and weaknesses and to improve the quality and outcomes of joint replacements. Therefore, extensive research and clinical trials are essential. The main aspects that are addressed in this Special Issue are related to new material, design and manufacturing considerations of implants, implant wear and its potential clinical consequence, implant fixation, infection-related material aspects, and taper-related research topics. This Special Issue gives an overview of the ongoing research in those fields. The contributions were solicited from researchers working in the fields of biomechanics, biomaterials, and bio- and tissue-engineering.

Download or read book Natural Fibres and Their Composites written by Vincenzo Fiore and published by . This book was released on 2021 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decades, natural fibers have received growing attention as alternatives to synthetic materials for the reinforcement of polymeric composites. Their specific properties, low price, health advantages, renewability and recyclability make natural fibers particularly attractive for these purposes. Furthermore, natural fibers have a CO2-neutral life cycle, in contrast to their synthetic counterparts. However, natural fibers are also widely known to possess several drawbacks, such as a hydrophilic nature, low and variable mechanical properties, poor adhesion to polymeric matrices, high susceptibility to moisture absorption and low aging resistance. Therefore, extensive research has been conducted on natural fiber-reinforced composites in the last 20 years. In this context, this book presents several interesting papers concerning the use of natural fibers for the reinforcement of polymer-based composites, with a focus on the evaluation of their mechanical performances, ballistic properties, rheological behavior, thermal insulation response and aging resistance in humid or aggressive environments.

Download or read book The P53 Protein written by Guillermina Lozano and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Decades of research on the tumor suppressor p53 have revealed that it plays a significant role as a "guardian of the genome," protecting cells against genotoxic stress. In recent years, p53 research has begun to move into the clinic in attempts to understand how p53 is frequently inactivated in-and sometimes even promotes-human cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine covers the rapid progress that has recently been made in basic and clinical research on p53. The contributors review new observations about its basic biology, providing updates on the functions of its isoforms and domains, the myriad stresses and signals that trigger its activation or repression, and its downstream effects on genome stability and the cell cycle that enforce tumor suppression in different cell and tissue types. They also discuss how p53 dysfunction contributes to cancer, exploring the various inherited and somatic mutations in the human TP53 gene, the impact of mutant p53 proteins on tumorigenesis, and the prognostic value and clinical outcomes of these mutations. Drugs that are being developed to respond to tumors harboring aberrant p53 are also described. This book is therefore essential reading for all cancer biologists, cell and molecular biologists, and pharmacologists concerned with the treatment of this disease.
