  • Publication number: 20240207396
    Abstract: An oligosaccharide vaccine for specific prevention of fungal infections and a method for preparing the same are provided. The vaccine is formed by conjugating a sulfhydrylated protein with oligosaccharide. The sulfhydrylated protein is formed by introducing a sulfhydryl group (—SH) to a carrier protein containing a primary amino group (—NH2), and then is conjugated with the oligosaccharide to form the oligosaccharide vaccine under the binding action of a bridging agent. The carrier protein is a non-humanized protein, and the oligosaccharide is a chitosan oligosaccharide mixture and/or chitin oligosaccharide mixture. The vaccine has strong immunogenicity, can activate Th17 cell immunity, and can recognize and protect infections caused by fungi.

  • Patent number: 5925529
    Abstract: This invention relates to peptide ligand discovery and is particularly directed to a method for the discovery of agonists for membrane bound receptors. The inventive detection system involves the use of a "tethered" ligand for probing receptor binding. The general detection system includes a membrane, a membrane bound receptor, and a chimeric ligand presenting molecule. This chimeric protein forms the tethered ligand and in turn includes a membrane domain, a linker domain, a ligand domain, and a cleavable terminal domain. The "ligands" of the system are exposed by the addition of a specific peptidase that cleaves at the designated sequence. The sequence of the ligand that produces signal as a result of the interaction between the agonist and receptor can be then be isolated using sib selection.
