    摘要: A novel adjuvant composition comprising a sterol (e.g., cholesterol, β-sitosterol, stigmasterol, ergosterol, and ergocalciferol) and saponin fraction (e.g., QS21, also known as QA21) in the form of an immunostimulating complex, or ISCOM, is disclosed. QS21 is an immunologically active saponin fraction having adjuvant activity derived from the bark of Quillaja Saponaria Molina. Previous attempts in the prior art to prepare ISCOMs comprising QS21 were unsuccessful. Thus, the instant application discloses the first successful attempt to prepare ISCOMs comprising purified QS21. Small unilamelar liposomes containing cholesterol, in the absence of any detergent, were prepared, followed by the addition of an aqueous solution of QS21. The claimed compositions will prove useful in the preparation of highly immunogenic vaccine compositions.

    摘要: A method of treating chronic hepatitis B is disclosed that comprises administering a T cell-stimulating amount of a vaccine to a patient. The vaccine comprises an immunogenic amount of chimeric, carboxy-terminal truncated hepatitis B virus nucleocapsid (core) protein (HBc) that is engineered for both enhanced stability of self-assembled particles and the substantial absence of nucleic acid binding by those particles. The chimeric protein molecule can include one or more immunogenic epitopes peptide-bonded to one or more of the N-terminus, the immunogenic loop or the C-terminus of HBc. The enhanced stability of self-assembled particles is obtained by the presence of at least one heterologous cysteine residue near one or both of the amino-terminus and carboxy-terminus of the chimer molecule.
