Abstract

Lectins: Methods and Protocols summarizes classic lectin technologies and advanced techniques with high throughputs and sensitivities. Chapters include methods and techniques for serial lectin-affinity chromatography procedure, lectin-probed western blot and histochemical analyses, quantitative interaction analyses based on equilibrium dialysis, isothermal calorimetry, surface plasmon resonance, techniques for elucidating functions of endogenous animal lectins, advanced methods on “engineer” novel lectins by evolutionary concepts, and special equipment. 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, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Lectins: Methods and Protocols seeks to aid not only lectin specialists but also non-experts including both young scientists.

Abstract

The group of pattern recognition receptors (PRRs) includes families of Toll-like receptors (TLRs), NOD-like receptors (NLRs), C-type lectin receptors (CLRs), RIG-I-like receptors (RLRs), and AIM-2-like receptors (ALRs). Conceptually, receptors constituting these families are united by two general features. Firstly, they directly recognize common antigen determinants of virtually all classes of pathogens (so-called pathogen-associated molecular patterns, or simply PAMPs) and initiate immune response against them via specific intracellular signaling pathways. Secondly, they recognize endogenous ligands (since they are usually released during cell stress, they are called damage-associated molecular patterns, DAMPs), and, hence, PRR-mediated immune response can be activated without an influence of infectious agents. So, pattern recognition receptors play the key role performing the innate and adaptive immune response. In addition, many PRRs have a number of other vital functions apart from participation in immune response realization. The fundamental character and diversity of PRR functions have led to amazingly rapid research in this field. Such investigations are very promising for medicine as immune system plays a key role in vast majority if not all human diseases, and the process of discovering the new aspects of the immune system functioning is rapidly ongoing. The role of Toll-like receptors in cancer was analyzed in certain reviews but the data are still scattered. This collection of reviews systematizes the key information in the field.

Abstract

The books described marine glycoconjugates. Two articles concern microalgal metabolites such as steroid and sphingoid glycoconjugates, and a glycoprotein from a sea cucumber with interesting biological activities, respectively. One article discusses the fatty acid composition and thermotropic behavior of glycolipids and other membrane lipids of green macrophyte Ulva lactuca. Three articles cover lectin subjects. One review article analyzes perspectives of marine and freshwater lectins’ application in experimental oncology and the therapy of oncological diseases; another article describes the use of a sponge lectin in the construction of a recombinant virus. The third article concerns the function of the immunity of a lectin in producing this compound crinoid. Two articles concern steroid glycosides from star?sh, and two others concern triterpene glycosides from sea cucumbers. One article describes the e?ect of a glycosaminoglycan from the sea cucumber Apostichopus japonicus on hyperglycemia in the liver of insulin-resistant mice. One article concerns the isolation of 10 new triterpene glycosides from a fungus associated with a sea cucumber. The article by Dworaczek et al. characterizes the O-speci?c polysaccharide (O-antigen) of a bacterial pathogen of common carp by chemical and immunochemical methods. In total, the Special Issue comprises14 articles, including the editorial and two reviews.

Abstract

Glycans (carbohydrate chains) of marine creatures are rich and diverse in polysaccharides, glycoproteins, and glycolipids. The chains that are metabolized by glycan-related enzymes (glycosyltransferases and glycosidases) are recognized by glycan-binding proteins (lectins) which regulate cellular processes such as growth, differentiation, and death. Marine glycomics that involves the genome and transcriptome accelerates our understanding of the evolution of glycans, glycan-related enzymes, and lectins. From 2017 to 2019, the Special Issue “Marine Glycobiology, Glycomics and Lectins” of the journal Marine Drugs published scientific articles and reviews, on the background of “glycobiology”—that is, glycan-based biosciences. The aim was to promote the discovery of novel biomolecules that contribute to drug development and clinical studies. This has great potential for establishing connections between the fields of both human health and marine life sciences.This book contains 11 scientific papers representing current topics in comprehensive glycosciences related to therapeutic agents from marine natural products, as outlined.

Abstract

This book contains original papers and reviews on carbohydrate research in medicine, authored by participants of the 29th International Carbohydrate Symposium, where this topic had a special emphasis. The focus on biological events involving carbohydrates and glycoconjugates has delivered reliable approaches for disease treatment and diagnosis. Research on carbohydrate-based compounds for therapeutic applications is illustrated in various contributions, namely those covering the development of novel agents against Alzheimer’s disease, e.g. the neuroprotective C-glucosylated flavones and the isonucleoside-based cholinesterase inhibitors. New imino sugar glucosidase inhibitors are also disclosed, a class of compounds with potential for diabetes, Gaucher disease or cancer treatment. Also the development of a useful synthetic method towards multivalent glycoclusters of biomedical interest is here highlighted. The relevance of glycomimetics in drug discovery and the progress on carbohydrates in early diagnosis and cancer treatment are reviewed. Noteworthy is the chitosan-based delivery system for drug oral administration, a new biomaterial-based approach to improve bioavailability. Another study on the conformation of Streptococcus capsular polysaccharide backbones by molecular modelling provides useful information for bacterial immunotherapeutic approaches. All original contributions and reviews clearly demonstrate the potential of glycosciences for innovation in medicinal (glyco)chemistry and pharmaceutical research.

Abstract

This book contains selected contributions on surface modification to improve the properties of solid materials. The surface properties are tailored either by functionalization, etching, or deposition of a thin coating. Functionalization is achieved by a brief treatment with non-equilibrium gaseous plasma containing suitable radicals that interact chemically with the material surface and thus enable the formation of rather stable functional groups. Etching is performed in order to modify the surface morphology. The etching parameters are selected in such a way that a rich morphology of the surfaces is achieved spontaneously on the sub-micrometer scale, without using masks. The combination of adequate surface morphology and functionalization of materials leads to superior surface properties which are particularly beneficial for the desired response upon incubation with biological matter. Alternatively, the materials are coated with a suitable thin film that is useful in various applications from food to aerospace industries.
