Coupling of proteins to liposomes and their role in understanding delayed type of hypersensitivity in human and mice.

ABSTRACT

Liposome-coupled lepromin was found to elicit a 3-week skin reaction in leprosy patients similar to that elicited by whole Mycobacterium leprae. The present study suggests that the presentation of antigens in a specific orientation is necessary for evoking delayed type hypersensitivity response in humans.
