Book Description
NK mediated expansion of T-cells preferentially expands CD8+ but not the CD4+ subsets in both healthy and cancer donors. This results in a lower CD4/CD8 ratio. While NK Cells target CD4+ helper T-cells they do not target their CD8+ cytotoxic counterparts. This study also reveals that Cancer patients NK cells have reduced cytotoxic ability and secrete much less IFN- than healthy donors and Osteoclast and sAJ2 expanded super-charged NKs intended for immunotherapeutic use from healthy donors expand more immune cells at a faster rate. NK immunotherapy was studied in combination with supplementation of probiotic bacteria in the humanized mouse model. NK immunotherapy increased CD8+ cytotoxic T cell population in immune tissue compartments and Increased immune infiltration in the tumor microenvironment, while probiotic supplementation further enhanced these effects, resulting in decreased tumor burden. This novel expansion technique can provide a non-invasive and highly effective treatment for the treatment of oral squamous cell carcinoma and other tumorigenic cancers.

Book Description
In the past few decades there has been incredible growth in "bionano"-related research, which has been accompanied by numerous publications in this field. Although various compilations address topics related to deoxyribonucleic acid (DNA) and protein, there are few books that focus on determining the structure of ribonucleic acid (RNA) and using RNA as building blocks to construct nanoarchitectures for biomedical and healthcare applications. RNA Nanotechnology is a comprehensive volume that details both the traditional approaches and the latest developments in the field of RNA-related technology. This book targets a wide audience: a broad introduction provides a solid academic background for students, researchers, and scientists who are unfamiliar with the subject, while the in-depth descriptions and discussions are useful for advanced professionals. The book opens with reviews on the basic aspects of RNA biology, computational approaches for predicting RNA structures, and traditional and emerging experimental approaches for probing RNA structures. This section is followed by explorations of the latest research and discoveries in RNA nanotechnology, including the design and construction of RNA-based nanostructures. The final segment of the book includes descriptions and discussions of the potential biological and therapeutic applications of small RNA molecules, such as small/short interfering RNAs (siRNAs), microRNAs (miRNAs), RNA aptamers, and ribozymes.

Book Description
In order to understand common conditions such as coeliac disease and Crohn’s disease, one must view the gut in its evolutionary context. This is the novel approach to the gut and its diseases that is adopted in this book. The first part tells the story of the evolution of the gut itself – why it came about and how it has influenced the evolution of animals ever since. The second part focuses on the evolution of immunity and how the layers of immune mechanisms are retained in the gut, resembling the strata revealed in an archeological dig. The final part, ‘The Gastro-Archeologist’, ties the first two together and highlights how understanding the gut and immune system in their evolutionary context can help us understand diseases affecting them. Ambitious in its scope but telling a unique story from a refreshingly novel perspective, the book offers an informative and enjoyable read. As the story of the gut, immunity and disease unfolds, the author aims to endow readers with the same sense of awe and excitement that the subject evokes in him. Difficult concepts are illustrated using simple and colourful analogies, and the main content is supplemented with anecdotes and unusual and amusing facts throughout the book. The book is intended for anyone with an interest in the gut, its immunity and diseases, ranging from school and college biology and biomedical students, to professionals working in the field, and to patients suffering from intestinal diseases who want to understand more about their conditions.

Book Description
This book elaborates on drug delivery targeting via intracellular delivery, specifically through the Receptor Mediated Endocytosis (RME) approach, due to the involvement of cellular receptors in various grave diseases. Targeted delivery relies on two basic approaches, passive and active targeting. While passive targeting approaches have shown great promise, the improved selectivity achieved with active targeting approaches has resulted in significantly higher efficacy. Interestingly there are numerous strategies for active targeting, many of which are already highlighted in , Targeted Drug Delivery: Concepts and Applications. Nevertheless an exciting and practical strategy for active targeting, which could enable high intracellular delivery, is through exploitation of RME. Cells in the body express receptors to enable various physiological and biochemical processes. As a result, many of these receptors are overexpressed in pathological conditions, or newer receptors expressed due to defective cellular functioning. RME is based on exploitation of such receptors to achieve intracellular delivery. While targeted delivery can have manifold applications, in this book we focus on two major and challenging therapeutic areas; i) Cancer and ii) Infectious Diseases. Targeted Intracellular Drug Delivery by Receptor Medicated Endocytosis discusses the major receptors that are useful for targeted delivery for these afflictions. A major section of this book is dedicated to details regarding their occurrence and location, the recognition domain of the receptor, structure activity relationship of substrate /ligand for selective binding, ligands explored, antagonists for ligand binding and relevance of these aspects for therapy of cancer and infectious diseases. These facets are elucidated with the help of specific examples from academic research and also emphasize commercial products, wherever relevant. In vitro cellular models relied on for assessing receptor mediated cellular targeting and in vivo models depicting clinical efficacy are focused on in a separate section. Finally, we briefly discuss the regulatory and toxicity issues that may be associated specifically with the RME approach of intracellular drug delivery.

Book Description
Tuberculosis (TB) remains one of the major infectious diseases of mankind although drugs for its treatment have been available for nearly 60 years. The standard short-course 6-month regimen used since about 1980 has helped to save millions of lives, but co-infection with HIV has had a devastating effect on the epidemic, and multidrug-resistant TB is a growing problem, particularly in communities with a high incidence of HIV. Following the declaration by the WHO in the early 1990s that TB was a 'global health emergency', interest in TB research and the development of new drugs has increased significantly. This volume reviews anti-TB chemotherapy with the emphasis on the actions and pharmacology of existing drugs and the development and evaluation of new agents. A close look is taken at new research regarding our existing drugs by some of the best-known specialists in the field, and historical aspects of these agents are reviewed from a modern perspective. The prospects for the introduction of new drugs and different approaches of how to assess them in adults and in children are discussed in detail. Several papers address the problems associated with drug resistance, its spread and diagnosis. Compiled by two editors from Cape Town, which has a particularly high incidence of TB and is a centre of tuberculosis research, this publication is an indispensable reference for anyone involved in the management of TB either as a researcher, clinician or administrator, and those working in drug development.

Book Description
This book is the first of its kind entirely dedicated to carbohydrate vaccines written by renowned scientists with expertise in carbohydrate chemistry and immunochemistry. It covers the synthesis of carbohydrate antigens related to bacteria and parasites such as: Heamophilus influenza, Streptococcus pnemoniae, Shigella flexneri, Candida albicans, Mycobacterium tuberculosis, and Chlamydia. The first three chapters are of wide interest as they cover fundamental concerns in new vaccine developments. The first one presents the immune system and how carbohydrate antigens are processed before protective antibodies are produced. It also illustrates antigen presentation in the context of major histocompatibility complexes (MHCs). The second chapter describes regulatory issues when carbohydrate vaccines are involved while the third one discuss several techniques used in conjugation chemistry and the implication of certain chemical linkages that may induce unexpected anti-linker antibodies. This section will be particularly appealing for those involved in drug-conjugate design, pro-drug developments, and drug vectorization. The book concludes with one chapter that illustrates the principle through which peptide antigens can functionally mimic carbohydrate epitopes, thus, unraveling the potential for peptide surrogates as replacement for complex carbohydrate structures. This book is unique in that it covers all aspects related to carbohydrate vaccines including the success story with the first semi-synthetic bacterial polysaccharide vaccine against Heamophilus influenza type b responsible for pneumonia and meningitis, liable for more than 600,000 infant deaths worldwide in developing countries. The book also presents regulatory issues and will thus be vital for government agencies approving candidate vaccines. It widely covers synthetic methodologies for the attachment of carbohydrate antigens to peptides and immunogenic protein carriers. Vaccines against bacterial antigens, cancer, and parasites are also discussed by worldwide experts in this field in details. No other book contains such a wide panel of different expertise. It will also be useful to students and researchers involved with the immunology of forreings antigens and how the under appreciated carbohydrate antigens are processed by the immune system.

Book Description
Medicine has entered a golden age in which therapeutic agents are becoming widely available due to advances in basic science and technology. As such, many drugs have been developed that target inflammatory processes and/or the immune system. This book is intended for health professionals examining the modulation of inflammation by immunotherapeutic drugs. The immune system fills the primordial role of host defense and resistance to infections with pathogenic microorganisms. Several hematopoietic-derived cells constituting the innate and adaptive immune systems cooperate to provide barriers for microbial colonization and/or promote pathogen destruction within the host. Conversely, many immune cells are also involved in the pathogenesis and propagation of chronic inflammatory diseases. The beginning of this book details various components of the immune system including the cell types, lymphoid tissues, soluble cytokines and surface molecules that are essential for host defense. Breakdowns in immune tolerance, or dysregulated immune responses to antigens derived from self tissues or innocuous sources, can lead to the development of autoimmunity or chronic inflammatory diseases. Pathophysiologic roles for the immune system are detailed in corresponding chapters on autoimmunity, epithelial surfaces (lungs, skin, intestine), and transplantation, with special emphasis placed on immunotherapeutic drug targets. The last section of the book focuses on treatments that stimulate our immune system to specifically target and fight infectious diseases and cancer. In each chapter, the medications used to treat various diseases/conditions in terms of their mechanism of action and other pharmacologic properties are detailed. Chapters begin with a table showing drug names and classifications. The importance of basic science and clinical trials cannot be understated in the context of drug development. As such, the discovery of certain medications that had a lasting impact in medicine and pharmacy are highlighted in chapter subsections named “Bench to Bedside.” Several clinical applications of immunotherapeutic drugs are described within end-of -chapter case studies including practice questions. The Pharmacology of Immunotherapeutic Drugs is a reference for immunologists and clinicians (medical doctors, pharmacists, nurses) examining the modulation of inflammatory processes by a variety of medications targeting the cells and mediators of our immune system.
