Available in PDF, EPUB and Kindle. Book excerpt: One of the barriers to rational vaccine design against evolving pathogens is our lack of mechanistic understanding of how innate and adaptive immune response systematically emerge and evolve. Immune response is comprised of dynamic events that require many components to cooperate collectively in a manner that spans a range of scales. These characteristics make it hard to predict mechanisms for immune response based solely on experimental observations. This thesis investigates various aspects of affinity maturation that are relevant to vaccination and therapeutic strategies but are not yet fully understood mechanistically, ranging from the evolution of the heterogeneity of the antibody population with respect to affinity to optimal design parameters for temporal dosing of vaccines. Our approach is to apply computational techniques to mathematically model the immune system, and being synergistic with complementary experiments. 1. As affinity maturation ensues, average affinity of antibodies increase with time while resulting affinity distribution becomes increasingly heterogeneous. To shed light on how the extent of this heterogeneity evolves with time during affinity maturation, we have taken advantage of previously published data of antibodies isolated from individual serum samples. Using the ratio of the strongest to the weakest binding subsets as a metric of heterogeneity (or affinity inequality), we find that after a single injection of small antigen doses, the ratio decreases progressively over time. This is consistent with Darwinian evolution in the strong selection limit. By contrast, neither the average affinity nor the heterogeneity evolves much with time for high doses of antigen, as competition between clones of the same affinity is minimal. 2. What are the aspects of affinity maturation being altered by various temporal patterns of antigen dosing? Certain extended-duration dosing profiles increase the strength of the humoral response, with exponentially-increasing(EI) dosage providing the greatest enhancement. While this is an exciting result, it is necessary to establish a mechanistic understanding of how immune response be enhanced to further engineer and optimize the temporal patterns. From our computational model, the effect is driven by enhanced capture of antigen in lymph nodes by evolving higher-affinity antibodies early in the GC response. We validate the prediction from independent experimental data, where EI dosage result in promoted capture and retention of the antigen in lymph nodes. To our knowledge, this work is the first to demonstrate a key mechanism for vaccine kinetics in the response of B cells to immunization, and may prove to be an effective method for increasing the efficacy of subunit vaccines. 3. Are there optimal dosing profiles that maximize total protection? That is, lead to the evolution of the most antibodies of high affinity? In extension of mechanistic studies in 2, we propose a stochastic simulation method that can be used as a tool for optimizing dosage protocols for vaccine delivery. Using this tool, we analyze experimental conditions for EI dosage induce suboptimal immune response and investigate two approaches for the optimization. Specifically, reducing the total dosage optimizes affinity of resulting antibodies, while total protection is optimal neither at constant or EI dosage but that corresponding to a "linear-like" dosing profile. Our approach can be extended to broader applications in vaccine design.

Book Synopsis Immunization Safety Review by : Institute of Medicine
Download or read book Immunization Safety Review written by Institute of Medicine and published by National Academies Press. This book was released on 2002-07-02 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: By two years of age, healthy infants in the United States can receive up to 20 vaccinations to protect against 11 diseases. Although most people know that vaccines effectively protect against serious infectious diseases, approximately one-quarter of parents in a recent survey believe that infants get more vaccines than are good for them, and that too many immunizations could overwhelm an infant's immune system. The Immunization Safety Review Committee reviewed the evidence regarding the hypothesis that multiple immunizations increase the risk for immune dysfunction. Specifically, the committee looked at evidence of potential biological mechanisms and at epidemiological evidence for or against causality related to risk for infections, the autoimmune disease type 1 diabetes, and allergic disorders.

Available in PDF, EPUB and Kindle. Book excerpt: Vaccines have made it possible to eradicate the scourge of smallpox, promise the same for polio, and have profoundly reduced the threat posed by other diseases such as whooping cough, measles, and meningitis. What is next? There are many pathogens, autoimmune diseases, and cancers that may be promising targets for vaccine research and development. This volume provides an analytic framework and quantitative model for evaluating disease conditions that can be applied by those setting priorities for vaccine development over the coming decades. The committee describes an approach for comparing potential new vaccines based on their impact on morbidity and mortality and on the costs of both health care and vaccine development. The book examines: Lessons to be learned from the polio experience. Scientific advances that set the stage for new vaccines. Factors that affect how vaccines are used in the population. Value judgments and ethical questions raised by comparison of health needs and benefits. The committee provides a way to compare different forms of illness and set vaccine priorities without assigning a monetary value to lives. Their recommendations will be important to anyone involved in science policy and public health planning: policymakers, regulators, health care providers, vaccine manufacturers, and researchers.
Book Synopsis Innovation in Vaccinology by : Selene Baschieri
Download or read book Innovation in Vaccinology written by Selene Baschieri and published by Springer Science & Business Media. This book was released on 2012-07-20 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prevention of infectious diseases by vaccination is one of the most significant achievements of modern medicine. During the 20th century, the average human life span in the developed world was about 70 years and it is expected to increase, with a significant portion of this increase directly attributed to vaccination. Since the first empiric vaccination trials, knowledge and technology have enormously evolved and new vaccination strategies are emerging on the market. Indeed, in spite of the great success, conventional vaccination strategies sometimes may result ineffective and, above all, may raise safety concerns. The aim of this book is to provide an overview of some of the technology platforms that have been realized or are currently under development to try to address unsolved and new issues in the field of vaccine development. Common denominator of all thematic areas described herein is the multidisciplinary teamwork. Most of the enabling technologies have been established by putting in the “melting pot” expertise in fields that, at first glance, may appear very far apart. I hope that this collection of articles will make the readers aware that vaccinology is rapidly taking a new direction, ceasing to be an empirical science.

Book Synopsis Innovations for Next-Generation Antibody-Drug Conjugates by : Marc Damelin
Download or read book Innovations for Next-Generation Antibody-Drug Conjugates written by Marc Damelin and published by Springer. This book was released on 2018-05-29 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibody-drug conjugates (ADCs) stand at the verge of a transformation. Scores of clinical programs have yielded only a few regulatory approvals, but a wave of technological innovation now empowers us to overcome past technical challenges. This volume focuses on the next generation of ADCs and the innovations that will enable them. The book inspires the future by integrating the field’s history with novel strategies and cutting-edge technologies. While the book primarily addresses ADCs for solid tumors, the last chapter explores the emerging interest in using ADCs to treat other diseases. The therapeutic rationale of ADCs is strong: to direct small molecules to the desired site of action (and away from normal tissues) by conjugation to antibodies or other targeting moieties. However, the combination of small and large molecules imposes deep complexity to lead optimization, pharmacokinetics, toxicology, analytics and manufacturing. The field has made significant advances in all of these areas by improving target selection, ADC design, manufacturing methods and clinical strategies. These innovations will inspire and educate scientists who are designing next-generation ADCs with the potential to transform the lives of patients.
