Immune responses to methamphetamine by active immunization with peptide-based, molecular adjuvant-containing vaccines.
نویسندگان
چکیده
Vaccines to methamphetamine (meth) were designed by covalently attaching a meth hapten (METH) to peptide constructs that contained a conformationally biased, response-selective molecular adjuvant, YSFKPMPLaR (EP54). Rats immunized with EP54-containing meth vaccines generated serum antibody titers to authentic meth, an immune outcome that altered meth self-administration. Immunization increased meth self-administration suggesting pharmacokinetic antagonism. The ability of immune sera to bind a METH-modified target protein dramatically decreased during and shortly after the meth self-administration assay, suggesting effective sequestration of free meth. However, the binding ability of immune sera to the METH-modified target protein was recovered 34 days after meth-free clearance time.

Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...

Objective(s): An efficient vaccine against TB is an urgent need. TB peptides are safe candidate but they are weak immunogens and needs to be potentiated by adjuvant/delivery systems. The main purpose of the present study was to determine the potential of CHT based NPs containing ESAT-6 antigen of M. tuberculosis for inducing mucosal and systemic immune responses after intranasal and subcutaneou...

Background: Vaccines capable of controlling tumor virus based infections are found difficult to develop due to the consistence latent infection in the host. DNA vaccines are attractive tools for the development of HPV vaccines and inducing antigen-specific immunity owing to the stability, simplicity of delivery, safety and cost effectiveness. However, there is a need to increase their potency b...
