Immunogenic composites capable of stimulating production of anti-peptide antibodies, pharmaceutical compositions employing these composites and methods of selectively inducing production of anti-peptide antibodies

摘要

An essentially pure immunogenic composite capable of selectively inducing antibody production in an animal to a peptide that if administered by itself to the animal without being conjugated to or mixed with additional substance does not stimulate production of anti-peptide antibody in the animal. This immunogenic composite comprises: a lipid and an amphipathic peptide. The amphipathic peptide if administered by itself to the animal without being conjugated to or mixed with additional substance does not stimulate production of anti-peptide antibody in the animal. The amphipathic peptide is covalently bound to the lipid in a peptide-lipid complex. The immunogenic composite has a vesicular or an amorphous particulate structure. Another embodiment of this immunogenic composite comprises: a lipid, the amphipathic peptide, and a hydrophilic peptide covalently bound together. The hydrophilic peptide if administered by itself to the animal without being conjugated to or mixed with additional substance does not stimulate production of anti-peptide antibody in the animal.
