Immunology of carbohydrate-based vaccines

Abstract

Carbohydrates are considered as promising targets for vaccine development against infectious diseases where cell surface glycan's on many infectious agents are attributed to playing an important role in pathogenesis. Understanding the relationship between carbohydrates and immune components at a molecular level is crucial for the development of well-defined vaccines. Recently, carbohydrate immunology research has been accelerated by the development of new technologies that contribute to the design of optimum antigens, synthesis of antigens and the studies of antigen-antibody interactions, and as a result, several promising carbohydrate-based vaccine candidates have been prepared in recent years. This article briefly presents the mechanistic pathways of polysaccharide, glycoconjugate, glycolipid and zwitterionic vaccines and the interplay between carbohydrate antigen and immune response.

Keywords: Carbohydrate; Glycoconjugate; Glycolipid; Immune response; Oligosaccharides; Polysaccharides; Vaccines; Zwitterionic.
