Book Description
This detailed volume introduces different methods to assess the structure and folding of bacterial amyloids and analyze their functions, either in vitro or in vivo. Despite their initial association with neurodegenerative diseases, there is now increasing evidence of alternative roles for amyloids, with beneficial aspects for cells. In particular, prokaryotes use amyloids as functional assemblies, where they are key players in the cell's physiology. Written for the highly successful Methods in Molecular Biology series, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, Bacterial Amyloids: Methods and Protocols is an ideal guide for experts and novices alike to further explore these crucial protein assemblies.

Book Description
Proteins suffer many conformational changes and interactions through their life, from their synthesis at ribosomes to their controlled degradation. Only folded and soluble proteins are functional. Thus, protein folding and solubility are controlled genetically, transcriptionally, and at the protein sequence level. In addition, a well-conserved cellular machinery assists the folding of polypeptides to avoid misfolding and ensure the attainment of soluble and functional structures. When these redundant protective strategies are overcome, misfolded proteins are recruited into aggregates. Recombinant protein production is an essential tool for the biotechnology industry and also supports expanding areas of basic and biomedical research, including structural genomics and proteomics. Although bacteria still represent a convenient production system, many recombinant polypeptides produced in prokaryotic hosts undergo irregular or incomplete folding processes that usually result in their accumulation as insoluble aggregates, narrowing thus the spectrum of protein-based drugs that are available in the biotechnology market. In fact, the solubility of bacterially produced proteins is of major concern in production processes, and many orthogonal strategies have been exploited to try to increase soluble protein yields. Importantly, contrary to the usual assumption that the bacterial aggregates formed during protein production are totally inactive, the presence of a fraction of molecules in a native-like structure in these assemblies endorse them with a certain degree of biological activity, a property that is allowing the use of bacteria as factories to produce new functional materials and catalysts. The protein embedded in intracellular bacterial deposits might display different conformations, but they are usually enriched in beta-sheet-rich assemblies resembling the amyloid fibrils characteristic of several human neurodegenerative diseases. This makes bacterial cells simple, but biologically relevant model systems to address the mechanisms behind amyloid formation and the cellular impact of protein aggregates. Interestingly, bacteria also exploit the structural principles behind amyloid formation for functional purposes such as adhesion or cytotoxicity. In the present research topic we collect papers addressing all the issues mentioned above from both the experimental and computational point of view.

Book Description
Alzheimer’s disease is an increasingly common form of dementia and despite rising interest in discovery of novel treatments and investigation into aetiology, there are no currently approved treatments that directly tackle the causes of the condition. Due to its multifactorial pathogenesis, current treatments are directed against symptoms and even precise diagnosis remains difficult as the majority of cases are diagnosed symptomatically and usually confirmed only by autopsy. Alzheimer’s Disease: Recent Findings in Pathophysiology, Diagnostic and Therapeutic Modalities provides a comprehensive overview from aetiology and neurochemistry to diagnosis, evaluation and management of Alzheimer's disease, and latest therapeutic approaches. Intended to provide an introduction to all aspects of the disease and latest developments, this book is ideal for students, postgraduates and researchers in neurochemistry, neurological drug discovery and Alzheimer’s disease.

Book Description
"Dancing protein clouds: Intrinsically disordered proteins in the norm and pathology" represents a set of selected studies on a variety of research topics related to intrinsically disordered proteins. Topics in this update include structural and functional characterization of several important intrinsically disordered proteins, such as 14-3-3 proteins and their partners, as well as proteins from muscle sarcomere; representation of intrinsic disorder-related concept of protein structure-function continuum; discussion of the role of intrinsic disorder in phenotypic switching; consideration of the role of intrinsically disordered proteins in the pathogenesis of neurodegenerative diseases and cancer; discussion of the roles of intrinsic disorder in functional amyloids; demonstration of the usefulness of the analysis of translational diffusion of unfolded and intrinsically disordered proteins; consideration of various computational tools for evaluation of functions of intrinsically disordered regions; and discussion of the role of shear stress in the amyloid formation of intrinsically disordered regions in the brain.
