Laminarin-CRM197 glycoconjugates were previously demonstrated to be immunogenic and confer protection against Candida albicans in mice. Laminarin consists of β-(1,3) glucan repeating units, with sporadic β-(1,6) branches. A set of short glucans was used to study the effect of the β-(1,6) branch on the antigenicity of linear β-(1,3) glucans. A linear β-(1,3) glucan hexasaccharide was selected as the
先前证明层粘连蛋白-CRM197糖缀合物具有免疫原性,并赋予小鼠抗白色念珠菌的保护作用。层粘连蛋白由β-(1,3)葡聚糖重复单元组成,具有零星的β-(1,6)分支。使用一组短葡聚糖来研究β-(1,6)支链对线性β-(1,3)葡聚糖的抗原性的影响。选择线性β-(1,3)葡聚糖六糖作为能够抑制层粘连蛋白和抗层粘连蛋白抗体结合的最佳片段。然后将六聚体偶联到CRM197上,并在小鼠中诱导显着滴度的特异性抗laminarin抗体,与Lam-CRM197偶联物产生的抗体相当。
