The advent of large-scale production and clinical trials of drugs developed through diverse production routes - involving viruses, microbes, plants, and animals - has increased the demand for an expanded capacity for pharmaceutical manufacturing. The production and purification of expressed proteins accounts for the bulk of the manufacturing costs for new therapeutics. Several pharmaceutical proteins have been synthesized by exploiting plant genetics allowing producers to override conventional approaches used to manufacture pharmaceuticals. The process of inserting a gene into a host organism for the purpose of harvesting a bioactive molecule for therapeutic use is known as molecular pharming. Frontiers in Molecular Pharming covers an array of topics relevant to understanding the structure, function, regulation, and mechanisms of action, biochemical significance, and usage of proteins and peptides as biomarkers, therapeutics, and vaccines for animals and humans. The contributions aim to highlight current progress in three areas, including system biology (in vivo characterization of proteins and peptides), molecular pharming for animals and molecular pharming for humans. The book gives special attention to computational biology tools, production platforms and fields (such as immunoinformatics) and applications of molecular pharming (such as veterinary therapeutics). A balance of theoretical concepts and practical applications is provided through 13 chapters. Frontiers in Molecular Pharming is an invaluable resource for students and researchers of biochemistry, molecular biology, and biotechnology. The book also serves as a springboard for understanding the process of how discoveries in protein and peptide research and its applications are coming to fruition.
