Definitions
- This invention relates to adjuvants for vaccines.
- Vaccines are a powerful tool in modern medical practice. They provide an effective, cost-efficient, method of preventing disease, and may also be used to stimulate the immune system in response to an existing infection. Modern vaccines are being developed to ensure enhanced immune responses to infection. Typically, vaccines require co-administration with an adjuvant.
- Adjuvants are stimulants used with specific antigens in vaccine compositions to induce powerful and disease- appropriate immune responses to the vaccine.
- mycobacterial antigens are routinely used to boost cell -mediated immunity as a component of Freund ' s complete adjuvant.
- extracts from Corynehacterium parvurn and Bordetella pertussi s are commonly used.
- T-helper 1 (Thl) cells secrete interleukin 2 (IL-2) and ⁇ -interferon, leading to an activation of cytotoxic T-cells and macrophages .
- T-helper 2 (Th2) cells secrete IL-4 and IL-5, which assist B cells and eosinophils .
- N-acyl homoserine lactones have been isolated from a number of bacteria, such as P otohacterium (Vibrio) fischeri , Pseudomonas aeruingosa, Erwinia carotovora,
- the present invention is based on the realisation that a T-helper 1 (Thl) response to vaccine compositions is not always appropriate, and that a T-helper 2 (Th2) response is preferable m some cases.
- a vaccine composition comprises an active agent (immunogen) and an adjuvant, wherein the adjuvant is capable of reducing T- helper cell type-1 responses and enhancing T-helper cell type-2 responses.
- the adjuvant described above is used m the manufacture of a vaccine composition for the prevention or treatment of infection .
- a homoserine lactone is used m the manufacture of a composition for oral administration with an active agent, to induce oral tolerance to the active agent.
- the adjuvants used m the present invention comprise compounds that are capable of reducing T-helper cell type-1 responses and enhancing T-helper cell type-2 responses. Although specific compounds that have these effects are provided m the specification, it is possible for the skilled person to identify further compounds by testing compounds for the desired effects . With knowledge of an appropriate test, it is possible for the skilled person to use conventional combinatorial chemistry-based approaches to identify further compounds that may have activity m the adjuvant compositions.
- the adjuvants of the invention promote the T-helper 2 response. This may be characterised by measuring IgGl m the presence of the adjuvant of the invention, and comparing this to that obtained using alum or phosphate buffered saline as the adjuvant. The adjuvants also reduce the T-helper 1 response m comparison to that observed for the same immunogen using alum or phosphate buffered saline as the adjuvant.
- the T-helper 1 response may be characterised by measuring IgG2a.
- a preferred embodiment of the invention is the use of N-acyl homoserine lactones (AHL') m the adjuvant compositions.
- AHL' N-acyl homoserine lactones
- OdDHL is most preferred.
- OdDHL suppresses tumour necrosis factor ⁇ (TNF ) and mterleukm-12 (IL-12) production by macrophages, leading to a reduction m Thl cell responses. Further, IgGl and IgE responses, m murine and human tissue cultures, respectively, are promoted.
- TNF tumour necrosis factor ⁇
- IL-12 mterleukm-12
- the adjuvants may be prepared for separate or co- administration with the vaccine.
- the adjuvant and vaccine are co-administered m the one composition.
- the vaccine may be any appropriate vaccine for the treatment/prevention of a particular disease, m particular any disease for which an enhanced Th2 response is desirable.
- the disease is a nematodal infection or a trypanosomal infection, e.g. infection by Necator americanus .
- the vaccine may be prepared by techniques known in the art. Appropriate immunogens will also be known to those skilled in the art. Immunogens may be of any suitable biological material that is capable of eliciting the appropriate immune response.
- the immunogen may be an attenuated microorganism or a protein or peptide fragment of sufficient size to generate the unique immune reaction against an infecting agent.
- the immunogen may be an antibody, e.g.
- Vaccines for hookworm infections are disclosed in Sen et al . , Vaccine, 2000; 18:1096-1102, m Ghosh et al . The Journal of Infectious Diseases, 1999; 180:1674-1681, and in Taylor et al . , J. Exp . Med . , 2000; 191 (8 ): 1429-1436.
- the type and concentrations of the vaccine and the adjuvant may be readily determined by a person skilled in the art.
- the composition may comprise 10 mg/ml of a vaccine and 100 ⁇ M homoserine lactone in the adjuvant, together with a pharmaceutically acceptable diluent.
- concentrations of vaccine will be m the range comprising of 10 mg - 10 ⁇ g/ml
- the adjuvant may be m the range of 10-100 ⁇ M .
- Acceptable diluents will be known to the skilled person, based on conventional adjuvant formulations.
- the vaccine may be administered by any convenient means, m particular, by oral, systemic or parentoral routes, or a combination of these.
- Oral tolerance may therefore be desirable m the present invention m the treatment of autoimmune disorders, where a patient's immune system is attacking self -antigens .
- the administration of a homoserine lactone compound together with autoantigens, via the oral route may induce tolerance to the autoantigens, resulting m reduced severity of the autoimmune disorder.
- the treatment may comprise collagen or myelm proteins as the autoantigen, to treat rheumatoid arthritis and multiple sclerosis, respectively.
- the induction of oral tolerance may be desirable for any protein-based therapy, e.g. antibody therapy.
- the homoserine compounds may therefore induce tolerance to antibodies, thereby enhancing their therapeutic efficacy.
