Abstract: The present disclosure relates to specific delivery of a lipid-peptide conjugate to immune cells ex vivo or in vivo for decreasing or increasing an immune response against therapeutically relevant antigens. The lipid-peptide-antigen is comprised of a peptide, a lipid, and a functional group that is degraded in a biological environment within cells to release the peptide for MHC presentation and provides a more efficient presentation of antigen epitopes by antigen presenting cells than peptide epitopes alone.

Abstract: The present disclosure relates to a method of loading a toll like receptor (TLR)7/8 agonist into a liposome using remote loading and a kit of parts suitable for the loading of a TLR7/8 agonist into a liposome by said method. The present disclosure further relates to a liposome comprising a salt of a TLR7/8 agonist in the liposome interior and to the use of said liposome for stimulation of an immune response and/or treatment of a clinical condition. Finally, the present disclosure relates to a TLR7/8 agonist which is suitable for being remotely loaded into a liposome.
