The use of lipopeptides or lipoproteins (I), designated macrophage activating lipopeptides (MALP), as a mucosal adjuvant for therapeutic or prophylactic vaccination viathe mucosa is new. Also claimed is the use of (I) (with some specific compounds excepted) as adjuvants for non-mucosal vaccination. The use of a lipopeptide or lipoprotein of formula (I) is claimed as a mucosal adjuvant for therapeutic or prophylactic vaccination viathe mucosa. [Image] R 1, R 27-25C alkyl, 7-25C alkenyl or 7-25C alkynyl; X : S, O or CH 2; R 3, R 4H or Me; and Y : sequence of 1-25 (preferably 12-25) amino acid residues, which is physiologically acceptable and not in itself immunogenic in the species to be treated; provided that the asterisked C atom has absolute R-configuration if X = S. An independent claim is also included for the use of (I) as adjuvant for non-mucosal vaccination, with the additional proviso that (I) is other than an S-(2,3-diacyloxypropyl)-cysteine peptide (I') of the sequence Asp-hcGly-Asn-Asn-Asp-Glu-Ser-Asn-Ile-Glu-Ser-Phe-Glu-Lys-Glu-Lys, where the amino acids in position 2 and optionally 3 at the N-terminal are optionally absent and/or 1 or 2 aminoacids may be deleted from the C-terminal. ACTIVITY : Immunostimulant. Mice were immunized intranasally on days 0, 7 and 14 with 40 mu g beta -galactosidase (as model antigen) or a mixture of 40 Microg beta -galactosidase and 1 Microg MALP-2 (Ia) as adjuvant. On day 28 serum samples were analyzed by enzyme-labeled immunosorbent assay for the beta -galactosidase-specific antibody titer. The titers, in absorption value units (OD 405 nm), were 0.25 in the absence of (Ia) and 0.30 in presence of (Ia). MECHANISM OF ACTION : None given. |
