Abstract: The link between cancer and aberrant glycosylation has recently become evident. Glycans and their altered forms, known as tumour-associated carbohydrate antigens (TACAs), are diverse, complex and difficult to target therapeutically. Lectins are naturally occurring glycan-binding proteins that offer a unique opportunity to recognise TACAs. T cells expressing chimeric antigen receptors (CARs) have proven to be a successful immunotherapy against leukaemias, but so far have shown limited success in solid tumours. We developed a panel of lectin-CARs that recognise the glycosphingolipid globotriaosylceramide (Gb3), which is overexpressed in various cancers, such as Burkitt's lymphoma, co...
Abstract: In plants, the topological organization of membranes has mainly been attributed to the cell wall and the cytoskeleton. Additionally, few proteins, such as plant-specific remorins have been shown to function as protein and lipid organizers. Root nodule symbiosis requires continuous membrane re-arrangements, with bacteria being finally released from infection threads into membrane-confined symbiosomes. We found that mutations in the symbiosis-specific SYMREM1 gene result in highly disorganized perimicrobial membranes. AlphaFold modelling and biochemical analyses reveal that SYMREM1 oligomerizes into antiparallel dimers and may form a higher-order membrane scaffolding structure. This ...

Handbook on Natural Pigments in Food and Beverages: Industrial Applications for Improving Color, Second Edition focuses on a color solution for a specific commodity, providing food scientists with a one-stop, comprehensive reference on how to improve the color of a particular food product. The book includes two new chapters that highlight the physical and biological fundamentals of color, as well as the specific use of curcumin and carthamin. Sections focus on specific industrial applications of natural colorants, with chapters covering the use of natural colorants in a variety of products. Other sections highlight technical formulation and potential health benefits of specific colorants. Va...
This volume presents a series of experimental protocols for glycan analysis using lectins and the functional analysis of lectins. A key feature in this book are two comprehensive overview chapters on lectin structures and a list of the all the lectins—these chapters discuss the latest findings in the field. The remainder of the book covers topics such as lectins from mammals, non-mammalian animals; plants, algae, fungi, protists, bacteria, and viruses. 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 tips on troubleshooting and avoiding known pitfalls. Cutting-edge and thorough, Lectin Purification and Analysis: Methods and Protocols is a valuable tool for any scientist interested in learning more about these life systems.
