An anti-candidiasis glycoconjugate vaccine was prepared via a tyrosine-selective alkynylation and a click chemistry mediated glycoconjugation sequence. It features a well-defined glycan, protein carrier, and connectivity. The construct, although with significantly lower carbohydrate loading and a shorter b-(1,3) glucan chain than the well-established anti-candidiasis vaccine derived from the random conjugation of laminarin at lysines, elicited a comparable level of specific IgG antibodies.
Elucidation of the molecular immunity of glycoconjugate vaccines has focused on the carbohydrate moiety, herein the effect of the corresponding conjugation sites is studied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
