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.

This is a superb publication that would be very useful to undergraduates, graduate students, postdoctoral researchers, and instructors involved in structural biology or biophysics courses or in research on protein structure-function relationships." --David Sheehan, ChemBioChem, 2011 "Introduction to Proteins is an excellent, state-of-the-art choice for students, faculty, or researchers needing a monograph on protein structure. This is an immensely informative, thoroughly researched, up-to-date text, with broad coverage and remarkable depth. Introduction to Proteins would provide an excellent basis for an upper-level or graduate course on protein structure, and a valuable addition to the libraries of professionals interested in this centrally important field." --Eric Martz, Biochemistry and Molecular Biology Education, 2012

Book Description
Despite being confined to the gastrointestinal tract, the gut microbiome has a wide impact on human physiology, supplementing its host’s biochemistry in a complex symbiotic relationship. Research in the field has evolved rapidly in the last decade, and we are now developing a better understanding of how our gut microbiome can influence our immune systems, metabolism, neurological signaling, and perhaps most unexpectedly, our brains; a phenomenon described as the gut-brain-axis. This book, ‘Handbook of Microbiome and Gut-Brain-Axis in Alzheimer’s Disease’, sets out to explore the complex role of the microbiome with regard to Alzheimer’s disease (AD). The microbiome is a critical and often overlooked aspect of immunity, which in turn plays a role in cognition. The book presents current research into the gut microbiota and its far-reaching impacts on cognitive function and neurodegeneration. Interventions, including probiotic supplementation, fecal transfer, and supplementation with microbial metabolites, are discussed, as is the use of certain probiotics to study the effects of the gut microbiota on behavior and cognitive function, and as potential therapeutics for AD. Other topics covered include the influence of the gut and oral microbiota on immune inflammatory signals: cytokines, neuroendocrine hormones, bacterial components, neuroactive molecules, and microbial metabolites. The book is divided into four sections, each covering a research area pertinent to the gut-brain-axis and its relationship with cognitive function and AD. It will be of interest to all those whose work includes the study and understanding of these complex, multi-variable biological mechanisms, particularly in the context of cognitive function and AD. The cover shows a color edited MRI image of a sagittal section of a neurological control brain of Dr. Giulio Maria Pasinetti.
