Covalent polar lipid-peptide conjugates for immunological targeting
First Claim
1. A composition of matter comprising a peptide, a polar lipid carrier, two linker functional groups and a spacer, wherein the spacer has a first end and a second end and wherein the polar lipid is attached to the first end of the spacer through a first linker functional group and the peptide is attached to the second end of the spacer through a second linker functional group.

Abstract
This invention relates to methods of facilitating the entry of peptides into cells and targeting such peptides to specific organelles within the cell. The invention provides methods for delivering and specific targeting of antigenically-active peptides to cells for the specific production of immunological reactivity against such peptides, as well as compositions and pharmaceutical compositions of matter comprising such peptides. This invention thereby provides improved methods for vaccine production and in vivo vaccination against pathogenic microorganisms. Methods for alleviating autoimmune disease and ameliorating tissue and organ transplant rejection using such conjugates are also provided.
