Download or read book Lectin in Host Defense Against Microbial Infections written by Shie-Liang Hsieh and published by Springer Nature. This book was released on 2020-03-09 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book systemically presents the latest research on lectins, covering all the major topics in the field, including the heterocomplex of lectins and Toll-like receptors, protective versus pathogenic functions in connection with microbial infections, and novel strategies for enhancing host immunity against infectious diseases caused by viruses, bacteria, and fungi. Lectins are a large group of glycan-binding proteins that recognize diverse glycan and non-glycan structures expressed on prokaryotic and eukaryotic cells, and are vital to cell-cell interactions, the attachment of microbes to host cells, and the recognition and activation of immune responses to exogenous and endogenous danger signals. The composition and structure of microbes are complex and include numerous ‘pathogen-associated molecular patterns’ or ‘damage-associated molecular patterns’. As such, microbes’ interactions with immune cells activate multiple innate immunity receptors and produce distinct inflammatory reactions, which can be protective to contain microbial invasion, or pathogenic to cause tissue damage and shock syndrome in the host. The book shares lessons learned from state-of-the art research in this field, highlights the latest discoveries, and provides insightful discussions on lectin-mediated inflammatory reactions, while also outlining future research directions.
Download or read book Elucidation of the Host Cell Membrane Associated Interaction Partners of Pseudomonas Aeruginosa and Its Lectins in Space and Time written by Sahaja Aigal and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Pseudomonas aeruginosa produces an abundance of virulence factors that aid in the establishment of bacterial invasion and infection in mammalian host cells. In this work, we investigated the host cell membrane-associated proteins that interact with Pseudomonas aeruginosa (PAO1) and its lectins, LecA and LecB. We used human lung epithelial cell line, H1299 as the cellular model for all the experiments as this bacterium is one of the major causes of severe lung infection. We found a novel cytoskeletal interaction partner of PAO1, namely the septin GTPases. When H1299 cells were infected with the pathogen, we observed cage-like as well as an amorphous ensemble of septins around it. We also found that knockdown (KD) or perturbation of septin function led to an increase in intracellular bacterial load. Additionally, we observed that septin function perturbation resulted in a significant reduction (≥70%) of viable bacterial count in the cell culture supernatant after 4 h of bacterial stimulation. While the wild-type cells could restrict the infection by expelling the septin-caged bacterium out, the septin function perturbed cells were less efficient in doing so. Septins, therefore, have a protective role against PAO1 infection. We found another interaction partner of PAO1 via its galactose-binding lectin LecA in H1299 cells. We observed that LecA associated with flotillin-1, a lipid raft marker which performs the role of an endocytic molecule and an intracellular cargo trafficker. In addition, LecA and flotillin-1 co-immunoprecipitated- this prompted us to investigate lectin trafficking in the absence of flotillin-1. Knockout of flotillin-1 did not impair LecA binding or internalization, but induced marginal changes in trafficking and kinetics. However, the invasion of whole bacteria was reduced by 50% in the absence of flotillin-1. We also found two other interaction partners of the bacterium via its fucose-binding lectin, LecB. We performed preliminary investigations on LecB internalization and found the glycoprotein receptor-CD44, a marker for CLIC/GEEC endocytic pathway to be associated with it. Since most pathogen interactions with the host cells require host cell binding and receptor clustering, we studied briefly the possibility of LecB mediated CD44 clustering at different time points using dSTORM microscopy. Preliminary investigation revealed that CD44 receptor clustering increased by ~2-fold and at the same time, the mean cluster size d ...

Download or read book Plant Lectins written by A. Pusztai and published by Cambridge University Press. This book was released on 1991 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and pharmacological properties of lectins. Lectins, which are most commonly found in plants, are widespread natural products with striking biological activities. Their specific ability to recognise and bind to simple or complex saccharides facilitates their role as effective information protein molecules. As agents of cell-to-cell recognition, lectins promote symbiosis between plants and specific nitrogen-fixing soil bacteria. As natural defensive molecules, they can protect plants against predators such as bacteria, fungi and insects. As part of our diet, lectins are powerful exogenous growth factors in the small intestine and influence our health, the digestive function and the bacterial ecology of the alimentary tract. Lectins are also important research tools in preparative biochemistry and cell science.
Download or read book Galectins written by Sean R. Stowell and published by Humana. This book was released on 2016-08-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galectins: Methods and Protocols is the first book solely dedicated to methodological approaches designed to study galectin function. The galectin family represents one of the most pleiotropic families, with individual members having been implicated in various aspects of nearly every biological process described, from RNA splicing to complex regulatory circuits that orchestrate adaptive immunity. Given the diverse roles of galectins in a variety of biological systems, studying these glycan binding proteins often requires the assimilation of diverse technical skills to fully appreciate their biological function. Their nearly ubiquitous expression and ability to bind highly modifiable carbohydrate ligands, in addition to a variety of other regulatory proteins, allows these glycan binding proteins (GBPs) to possess the capacity to regulate a wide variety of biological processes. Individual chapters are dedicated to examining salient features of galectin functions. Written in the 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 protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Galectins: Methods and Protocols seeks to serve both professionals and novices with a useful framework when examining galectin function for many years to come.

Download or read book The Rhizobiaceae written by Herman P. Spaink and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Rhizobiaceae, Molecular Biology of Model Plant-Associated Bacteria. This book gives a comprehensive overview on our present molecular biological knowledge about the Rhizobiaceae, which currently can be called the best-studied family of soil bacteria. For many centuries they have attracted the attention of scientists because of their capacity to associate with plants and as a consequence also to specifically modify plant development. Some of these associations are beneficial for the plant, as is the case for the Rhizobiaceae subgroups collectively called rhizobia, which are able to fix nitrogen in a symbiosis with the plant hosts. This symbiosis results in the fonnation of root or stem nodules, as illustrated on the front cover. In contrast, several Rhizobiaceae subgroups can negatively affect plant development and evoke plant diseases. Examples are Agrobacterium tumefaciens andA. rhizogenes which induce the formation of crown galls or hairy roots on the stems of their host plants, respectively (bottom panels on front cover). In addition to the obvious importance of studies on the Rhizobiaceae for agronomy, this research field has resulted in the discovery of many fundamental scientific principles of general interest, which are highlighted in this book. To mention three examples: (i) the discovery of DNA transfer of A.

Download or read book Lectins and Glycobiology written by Hans-Joachim Gabius and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intriguing complexity, precision, and regulation of the wide range of biologi cal processes is determined by intricate mechanisms of molecular recognition. Their nature is under intense scrutiny. In addition to the well-appreciated interac tion of proteins either with amino acid or nucleotide sequences, the investigation of their interplay with carbohydrate elements of cellular glycoconjugates current ly exerts increasing attraction. In the group of carbohydrate-binding proteins, lec tins are distinguished from antibodies or ligand-affecting enzymes, according to the most recent definition. The thorough analysis of their structure and function is considered as a focus to collect a critical mass of information for delineating details of a further array of biochemical processes with pivotal physiological im pact. Following an already century-long history of scientific description, reflected by subjectively chosen highlights (see the Brief History of Lectin Research at page VI), the excitement in glycobiological research that prevails today can easily be ex plained by our growing awareness of the multifarious significance of a sugar-code system of biological information. This present notion unmistakably has an im pact on lines of research in diverse disciplines like cell and molecular biology, histochemistry, or clinical sciences. It also prompts inherent practical questions such as how to obtain lectins, or how to employ them as instruments in various assay systems with the best possible results. Thus, this book is devoted intentionally to cover the techniques in different research fields that deal with lectins.
