Book Description
Vaccines have benefited global health by controlling or eradicating life threatening diseases. With better understanding of infectious diseases and immunity, more interest has been placed on stimulating mucosal immune responses with vaccines as mucosal surfaces function as a first line of defense against infections. Progress made in nanoparticle research, in particular the successful use of liposomes for drug delivery, has made liposomes an attractive candidate for vaccine delivery. Here, we investigate the efficacy of using a novel nanoparticle system, Interbilayer Crosslinked Multilamellar Vesicles (ICMVs), as a mucosal vaccine to stimulate mucosal and systemic CD8 immunity. We first assessed the ability of ICMVs to elicit mucosal CD8 response, against the model antigen ovalbumin (OVA), by administration of the nanoparticles through the lungs. We explored the use of 2 different Toll-like receptor agonists (TLRa), monophosphoryl lipid A (MPLA) and Polyinosinic:polycytidylic acid (poly (I:C) or pIC) added to ICMVs as adjuvants. Pulmonary administration of ICMV with both adjuvants was found to give the most potent CD8 T cell response in both systemic and mucosal compartments. We looked further into the quality of the immune response and detected the presence of antigenspecific memory CD8 T cells in the system at ~2.5 months after immunization. The majority of these cells were found to be effector memory cells (CD44hiCD62Llo) and expressed markers for long term survival (CD127hiKLRG1lo), suggesting that long term protection against infection can be induced by pulmonary delivery of ICMVs. We also explored using this system to deliver a model HIV peptide epitope, AL 1, and ICMV successfully induced CD8 response against this epitope. Animals immunized against AL 11 were challenged with a live virus expressing the same epitope and protection was seen only in the pulmonary ICMV treatment group. Virus was delivered via the lungs and viral titre was decreased in both the lungs and ovaries. Neither the soluble form of the vaccine or ICMV delivered via parenteral injection conferred protection. Safety of the ICMV system was also assessed and no significant negative effects were observed in body weight and histological analysis on lungs. Finally, mechanism of using nanoparticles as pulmonary vaccines was investigated to gain better understanding in how particulate vaccine and route of immunization improved the efficacy of a vaccine. Overall, this thesis describes a comprehensive study of systemic and mucosal CD8 responses generated by pulmonary delivery of a novel nanoparticle system. This data provides evidence that mucosal delivery of ICMVs can safely and effectively stimulate disseminated mucosal CD8+ T cells at sites relevant for protection against mucosal infection. A better understanding of nanoparticles for pulmonary immunization was also gained.

Book Description
This book provides a comprehensive overview of how use of micro- and nanotechnology (MNT) has allowed major new advance in vaccine development research, and the challenges that immunologists face in making further progress. MNT allows the creation of particles that exploit the inherent ability of the human immune system to recognize small particles such as viruses and toxins. In combination with minimal protective epitope design, this permits the creation of immunogenic particles that stimulate a response against the targeted pathogen. The finely tuned response of the human immune system to small particles makes it unsurprising that many of the lead adjuvants and vaccine delivery systems currently under investigation are based on nanoparticles. Provides a comprehensive and unparalleled overview of the role of micro- and nanotechnology in vaccine development Allows researchers to quickly familiarize themselves with the broad spectrum of vaccines and how micro- and nanotechnologies are applied to their development Includes a combination of overview chapters setting out general principles, and focused content dealing with specific vaccines, making it useful to readers from a variety of disciplines

Book Description
Many potential applications of synthetic and systems biology are relevant to the challenges associated with the detection, surveillance, and responses to emerging and re-emerging infectious diseases. On March 14 and 15, 2011, the Institute of Medicine's (IOM's) Forum on Microbial Threats convened a public workshop in Washington, DC, to explore the current state of the science of synthetic biology, including its dependency on systems biology; discussed the different approaches that scientists are taking to engineer, or reengineer, biological systems; and discussed how the tools and approaches of synthetic and systems biology were being applied to mitigate the risks associated with emerging infectious diseases. The Science and Applications of Synthetic and Systems Biology is organized into sections as a topic-by-topic distillation of the presentations and discussions that took place at the workshop. Its purpose is to present information from relevant experience, to delineate a range of pivotal issues and their respective challenges, and to offer differing perspectives on the topic as discussed and described by the workshop participants. This report also includes a collection of individually authored papers and commentary.

Book Description
This comprehensive volume compiles the concepts essential for the understanding of the pharmaceutical science and technology associated with the delivery of subunit vaccines. Twenty-one chapters are divided into four main parts: (I) Background; (2) Delivery Systems for Subunit Vaccines; (3) Delivery Routes, Devices and Dosage Forms; and (4) Pharmaceutical Analysis and Quality Control of Vaccines. Part one provide a basic background with respect to immunology and general vaccine classification. In part two, it presents representative types of vaccine delivery systems individually with focus on the physicochemical properties of the systems and their significance for the immune response they stimulate. These delivery systems include aluminum adjuvants, emulsions, liposomes, bilosomes, cubosomes/hexosomes, ISCOMs, virus-like particles, polymeric nano- and microparticles, gels, implants and cell-based delivery systems. Following these chapters, part three addresses the challenges associated with vaccine delivery via specific routes of administration—in particular subcutaneous, intramuscular, oral, nasal, pulmonary, transdermal and vaginal administration. Furthermore, the specific administration routes are discussed in combination with device technologies relevant for the respective routes as well as dosage forms appropriate for the device technology. Finally, the fourth part concerns pharmaceutical analysis and quality control of subunit vaccines.
