Delivery vehicle for bioactive molecule

摘要

A delivery vehicle for bioactive molecules such as antigens via an oral or injection route to present to the immune system the active molecule in a protected carrier which allows slow release of the molecules. Antigens are aggregated with cell fragments and encapsulated in a polysaccharide biofilm such as N-acetyl glucosamine. The encapsulated microparticles attach to a mucosal surface such as the gut lining and resist breakdown by gastric acid secretions. These microparticle delivery vehicles are useful for delivering oral vaccines for humans and animals.
