Download or read book Progress in the Search for Ricin A Chain and Shiga Toxin Inhibitors written by Yan Bai and published by . This book was released on 2009 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ricin and Shiga toxin type 1 are potent cytotoxins known as ribosome inhibition proteins, abbreviated RIPs. Proteins of this family shut down protein synthesis by removing a critical adenine in the conserved stem-loop structure of 28S rRNA. Due to its exquisite cytotoxicity, the plant toxin ricin has been used as a biological warfare agent. Although great achievement has been made on ricin research, including catalytic mechanism and structure analysis, there is still no specific treatment available for ricin exposure. In addition, ricin A chain inhibitors may also be useful against the homologous bacterial proteins shiga toxins, which are responsible for dysentery, and diseases related to food poisoning, including hemolytic uremic syndrome. Previous study on RTA inhibitor search has provided a number of substrate analog inhibitors, all of which, however, are weaker inhibitors. Therefore, the goal of this work is to improve the binding affinity of known inhibitors and to discovery new scaffolds for inhibitor discovery and development. In this work, multiple approaches were employed for this purpose, including optimizing known inhibitors and searching new inhibitors by Virtual Drug Screening (VDS) and High Throughput Screening (HTS). A number of new RTA inhibitors were discovered by these strategies, which provide a variety of pharmacophores for RTA inhibitor design, and also added a new line of evidence for VDS as an advanced technology for drug discovery and development.

Download or read book Biological Toxins and Bioterrorism written by P. Gopalakrishnakone and published by Springer. This book was released on 2015-01-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological toxins are an important part of our world, a reality with which we need to cope, so in parallel with understanding their mechanisms of action and thereby improving our fundamental knowledge, there are successful efforts to utilize them as therapeutics against some debilitating human and animal diseases. In view of the complexity of different types of biotoxins and the broad range of toxin structure, physiology, utility, and countermeasures including regulatory issues, it was thus aimed to compile a book on biotoxins and bioweapons. This reference work in the Toxinology handbook series gathers together knowledge from around the globe about naturally inspired and manufactured biological weapons. The authors describe how they work; how authorities may detect their presence, prevent their use, and diagnose their impacts; and the means by which medical and paramedical professionals may treat victims. Also described are how they have been used to further our knowledge and what insights they have given us into evolutionary and physiological processes. Finally, it is also discussed how these toxins can be used as therapeutics and what the implications of such therapeutics are to their use as biothreat agents. This volume provides a reference accessible to scientists, educators, and medical experts alike with an interest in biotoxins, focusing on the major toxins used as bioweapons. Regulatory agencies will also benefit from the information provided in this book. Some in the intended audience may need to understand how they elicit their effects and how we can defend ourselves against them. Others may be interested in the sometimes colorful histories that surround this subset of biotoxins that can be and, in some cases, have been used as weapons.

Download or read book Immunotoxins written by Arthur E. Frankel and published by Springer Science & Business Media. This book was released on 1988-05-31 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Where do you begin to look for a recent, authoritative article on the diagnosis or management of a particular malignancy? The few general oncology textbooks are generally out of date. Single papers in specialized journals are informative but seldom comprehensive; these are more often preliminary reports on a very limited number of patients. Certain general journals frequently publish good indepth reviews of cancer topics, and published symposium lectures are often the best overviews available. Un fortunately, these reviews and supplements appear sporadically, and the reader can never be sure when a topic of special interest will be covered. Cancer Treatment and Research is a series of authoritative volumes which aim to meet this need. It is an attempt to establish a critical mass of oncology literature covering virtually all oncology topics, revised frequently to keep the coverage up-to-date, easily available on a single library shelf or by a single personal subscription. We have approached the problem in the following fashion. First, by dividing the oncology literature into specific subdivisions such as lung cancer, genitourinary cancer, pediatric oncology, etc. Second, by asking eminent authorities in each of these areas to edit a volume on the specific topic on an annual or biannual basis. Each topic and tumor type is covered in a volume appearing frequently and predictably, discussing current diagnosis, staging, markers, all forms of treatment modalities, basic biology, and more.
Download or read book Toxic Plant Proteins written by J. Michael Lord and published by Springer Science & Business Media. This book was released on 2010-07-20 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many plants produce enzymes collectively known as ribosome-inactivating proteins (RIPs). RIPs catalyze the removal of an adenine residue from a conserved loop in the large ribosomal RNA. The adenine residue removed by this depurination is crucial for the binding of elongation factors. Ribosomes modified in this way are no longer able to carry out protein synthesis. Most RIPs exist as single polypeptides (Type 1 RIPs) which are largely non-toxic to mammalian cells because they are unable to enter them and thus cannot reach their ribosomal substrate. In some instances, however, the RIP forms part of a heterodimer where its partner polypeptide is a lectin (Type 2 RIPs). These heterodimeric RIPs are able to bind to and enter mammalian cells. Their ability to reach and modify ribosomes in target cells means these proteins are some of the most potently cytotoxic poisons found in nature, and are widely assumed to play a protective role as part of the host plant’s defenses. RIPs are able to further damage target cells by inducing apoptosis. In addition, certain plants produce lectins lacking an RIP component but which are also cytotoxic. This book focuses on the structure/function and some potential applications of these toxic plant proteins.

Book excerpt: This volume presents detailed laboratory protocols for in vitro synthesis of mRNA with favorable properties, its introduction into cells by a variety of techniques, and the measurement of physiological and clinical consequences such as protein replacement and cancer immunotherapy. Synthetic techniques are described for structural features in mRNA that provide investigational tools such as fluorescence emission, click chemistry, photo-chemical crosslinking, and that produce mRNA with increased stability in the cell, increased translational efficiency, and reduced activation of the innate immune response. Protocols are described for clinical applications such as large-scale transfection of dendritic cells, production of GMP-grade mRNA, redirecting T cell specificity, and use of molecular adjuvants for RNA vaccines. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Synthetic mRNA: Production, Introduction into Cells, and Physiological Consequences is a valuable and cutting-edge resource for both laboratory investigators and clinicians interested in this powerful and rapidly evolving technology.
Download or read book Pathogenesis of Shigellosis written by P.J. Sansonetti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shigellosis is present all over the world. Anyone traveling in developing countries knows that the control of this invasive disease of the intestine is a priority task for physicians and public health authorities. Victims are essentially young children, and complications such as the hemolytic uremic syndrome make shigellosis a systemic disease rather than simply an infection of the colonic mucosa. However, "Westerners" should not consider shigeJlosis as an unlikely threat of the tropics. The disease arises in industrialized countries as soon as breaches in sanitation appear. A few months ago, at least 500 people developed shigellosis in northern France in an outbreak of Shigella sonnei infection due to accidental contamination of an urban water delivery system. The pathogenesis of shigellosis is an extraordinary topic of research because study of the invasion of the colonic mucosa addresses fundamental questions on. the molecular and cellular mechanisms by which a bacterial pathogen can pene trate non phagocytic cells, survive, multiply, spread in the intra cellular compartment, and eventually kill host cells. Further development of the infection within subepithelial tissues as well as the mechanisms that contribute to the eradication of this process have barely been studied.
