This first title on the topic provides complete coverage, including the molecular basis, production and possible biomedical applications. Written by the most prominent academic researchers in the field as well as by researchers at one of the world's leading companies in industrial production of minicircle DNA, this practical book is aimed at everyone who is directly or indirectly involved in the development of gene therapies.
Since the discovery of the molecular structure of genes and the unveiling of the molecular basis of numerous human diseases, scientists have been fas- nated with the possibility of treating certain diseases by transducing foreign DNA into the affected cells. Initially, it was proposed that the foreign DNA could either replace defective nonfunctional genes, or code for therapeutic proteins. This concept has evolved into the rapidly growing field of gene therapy. Even though surgery, radiotherapy, and chemotherapy are widely ava- able and routinely used for cancer treatment, these therapies fail to cure approximately 50 percent of cancer patients. Therefore, since it is a disease characterized by aberrant gene expression, cancer has been a target of gene therapy research since the inception of this treatment modality. Numerous cancer gene therapy strategies are currently being investigated, including gene replacement therapy, the regulation of gene expression to modulate immu- logical responses to tumors, the direct killing of tumor cells, and direct int- ference with tumor growth. In this context, gene transfer systems, tumor-specific expression vectors, and novel therapeutic genes have been extensively st- ied. All these strategies aim for the selective destruction of human malignant disease while circumventing the destruction of nonmalignant cells and tissues thereby minimizing toxicity to the patient.
The book addresses the basics, applications, and manufacturing of plasmid biopharmaceuticals. The survey of the most relevant characteristics of plasmids provides the basics for designing plasmid products (applications) and processes (manufacturing). Key features that the authors include in the book are: i) consistency and clear line of direction, ii) an extensive use of cross-referencing between the individual chapters, iii) a rational integration of chapters, iv) appellative figures, tables and schemes, and v) an updated, but selected choice of references, with a focus on key papers.
Protein transport into and across membranes is a fundamental process in bacteria that touches upon and unites many areas of microbiology, including bacterial cell physiology, adhesion and motility, nutrient scavenging, intrabacterial signaling and social behavior, toxin deployment, interbacterial antagonism and collaboration, host invasion and disruption, and immune evasion. A broad repertoire of mechanisms and macromolecular machines are required to deliver protein substrates across bacterial cell membranes for intended effects. Some machines are common to most, if not all bacteria, whereas others are specific to Gram-negative or Gram-positive species or species with unique cell envelope properties such as members of Actinobacteria and Spirochetes. Protein Secretion in Bacteria, authored and edited by an international team of experts, draws together the many distinct functions and mechanisms involved in protein translocation in one concise tome. This comprehensive book presents updated information on all aspects of bacterial protein secretion encompassing: Individual secretory systems–Sec, Tat, and T1SS through the newly discovered T9SS Mechanisms, structures, and functions of bacterial secretion systems Lipoprotein sorting pathways, outer membrane vesicles, and the sortase system Structures and roles of surface organelles, including flagella, pili, and curli Emerging technologies and translational implications Protein Secretion in Bacteria serves as both an introductory guide for students and postdocs and a ready reference for seasoned researchers whose work touches on protein export and secretion. This volume synthesizes the diversity of mechanisms of bacterial secretion across the microbial world into a digestible resource to stimulate new research, inspire continued identification and characterization of novel systems, and bring about new ways to manipulate these systems for biotechnological, preventative, and therapeutic applications.
This primer introduces the challenges and opportunities of applying synthetic biological techniques to mammalian cells, tissues, and organisms. It covers the special features that make engineering mammalian systems different from engineering bacteria, fungi, and plants, and provides an overview of current techniques. A variety of cutting-edge examples illustrate the different purposes of mammalian synthetic biology, including pure biomedical research, drug production, tissue engineering, and regenerative medicine.
Since newly created beings are often perceived as either wholly good or bad, the genetic alteration of living cells impacts directly on a symbolic meaning deeply imbedded in every culture. During the earlier years of gene expression research, te- nological applications were confined mainly to academic and industrial laboratories, and were perceived as highly beneficial since molecules that were previously unable to be separated or synthesized became accessible as therapeutic agents. Such were the success stories of hormones, antibodies, and vaccines produced in the bacterium Escherichia coli. Originally this bacterium gained fame among humans for being an unwanted host in the intestine, or worse yet, for being occasionally dangerous and pathogenic. H- ever, it was easily identified in contaminated waters during the 19th century, thus becoming a clear indicator of water pollution by human feces. Tamed, cultivated, and easily maintained in laboratories, its fast growth rate and metabolic capacity to adjust to changing environments fascinated the minds of scientists who studied and modeled such complex phenomena as growth, evolution, genetic exchange, infection, survival, adaptation, and further on—gene expression. Although at the lower end of the complexity scale, this microbe became a very successful model system and a key player in the fantastic revolution kindled by the birth of recombinant DNA technology.
The induction of antigen-specific immune responses after in vivo transfection with expression plasmids has triggered a revolution of vaccine research. After a first hype, evoked by the fascinating options of this method, clinical studies did not reach the ambitious aims and a phase of disillusion ensued. It became obvious that Gene vaccines displayed a weaker immunogenicity in humans than had been observed in the mouse models. Meanwhile these hurdles have been overcome and gene vaccines undergo a renaissance. The present book gives an update of the “world of naked gene vaccines”, namely DNA and RNA vaccines. Its content ranges from general mechanisms, inherent immunostimulatory properties and the vast potential to modulate immune responses, to recent successful clinical studies and approved veterinary gene vaccines. Beyond the state-of-the-art of genetic immunization, the reader will be stimulated with a chapter addressing “burning questions”.
