ANTIGEN-AND-DRUG VEHICLE COMPRISING SYNTHETIC PEPTIDE, AND MUCOSAL VACCINE USING THE SAME

摘要

Disclosed are an antigen-and-drug (AD) vehicle and a mucosal vaccine utilizing a novel synthetic peptide. The antigen-and-drug (AD) vehicle capable of inducing the production of secretory IgA antibodies, which is a complex of a synthetic peptide having the following amino acid sequence: PVHLKRLm (m is 11 to 15 or 16 to 20, e.g., peptide of SEQ. ID. NO: 1) or KnLm (n is 4 to 8 and m is 11 to 20, e.g., peptide of (SEQ. ID. NO: 2 or 3), and a lipid(s). The mucosal vaccines is obtainable by allowing a mucosal-immunity-IgA-inducing amount of an antigen to coexist with, contact, be captured by, or be adsorbed onto the AD vehicle.
