The present invention provides synthetic
Moraxella catarrhalis
lipooligosaccharide (LOS)-based oligosaccharides and conjugates containing various
M. catarrhalis
serotype-specific oligosaccharide antigens or various core
M. catarrhalis
oligosaccharide structures or motifs corresponding to one or more of the three major serotypes and/or members within a given serotype. The oligosaccharides may be synthesized by a chemical assembly methodology relying on a limited number of monosaccharide and disaccharide building blocks. The invention further provides
M. catarrhalis
LOS-based immunogenic and immunoprotective compositions and antibodies derived therefrom for diagnosing, treating, and preventing infections caused by
M. catarrhalis.
本发明提供了基于合成Moraxella catarrhalis脂多糖(LOS)的寡糖和共轭物,其中包含各种M. catarrhalis血清型特异性寡糖抗原或对应于给定血清型内的三种主要血清型和/或成员的各种核心M. catarrhalis寡糖结构或基序。这些寡糖可以通过化学组装方法合成,该方法依赖于有限数量的单糖和二糖构建块。本发明还提供了基于M. catarrhalis LOS的免疫原和免疫保护组合物以及由此产生的抗体,用于诊断、治疗和预防由M. catarrhalis引起的感染。
