Vaccines, synthetic

Other types of branched peptide dendrimers, known as multiple antigen peptides (MAPs), have been synthesized to mimic proteins for applications, for instance as synthetic vaccines, serodiagnostics, peptide inhibitors and intracellular delivery vehicles. Since this concept has been recently described in detail elsewhere [11], only the conceptual framework will be briefly presented here. Tam and coworkers have developed a dendritic core based on lysine units for the construction of MAPs [12-15] (Fig. 3). Carrying antigens at their periphery these MAPs have been designed to increase antigenicity and immunogenicity of peptides. [Pg.139]

The development of vaccines is one of the most successful practical applications in immunology and in this field it is currently fashionable to make the reductionist claim that it will soon be possible to design effective synthetic vaccines on the basis of our knowledge of the molecules involved in immunological interactions. It seems to me that this claim arises from an unwarranted faith in the power of a reductionist approach for solving complex biological problems. Such a claim does not take into account that the protection against disease that can be achieved by vaccination is a... [Pg.47]

In the rare case when a peptide showing some promise has been identified, further immunization trials are necessary to establish its value as a practical synthetic vaccine. Since peptides are usually poor immunogens and do not mimic well the conformation of the corresponding antigenic site in the... [Pg.63]

Similar synthetic vaccines have also been constructed which confer immunological protection against bacterial toxins, including diphtheria and cholera toxins. While coupling to a carrier is generally required to elicit an immunological response, some carriers are inappropriate due to their ability to elicit a hypersensitive reaction, particularly when repeat injections are undertaken. Such difficulties can be avoided by judicious choice of carrier. Often a carrier normally used for vaccination is itself used, e.g. tetanus toxoid has been used as a carrier for peptides derived from influenza haemagglutinin and Plasmodium falciparum. [Pg.445]

Precise definition of the host-protection epitope(s) of the Taenia and Echinococcus vaccine antigens would be valuable if it were to lead to the development of a synthetic vaccine or provide reagents to assist with quality control of vaccine production. Identification of a limited number of host-protective fragments may allow the recombinant antigen to be replaced by synthetic peptides. This would have significant advantages in the production... [Pg.292]

The formation of CC bonds to prepare glycoconjugates has also gained some attention. For example, Diels-Alder cycloaddition has allowed the preparation of synthetic glycoproteins [144] and the construction of a synthetic vaccine candidate against Neisseria meningitidis A [145], These methods relied on a pretagging step to create suitable protein reactants. [Pg.519]

Some key aspects have to be considered when designing such synthetic vaccines because the immunogenic activity of the conjugate depends on the nature of the hapten, the loading onto the protein, and the characteristics of the carrier. In... [Pg.521]

Bioconjugates play an important role in several fields of biomolecular and biomedicinal sciences. Protein/polypeptide-based conjugates with covalently attached epitope peptides are considered as potential synthetic vaccine candidates and/or target antigens in affinity-based bioassays (e.g., ELISA, BIACORE) (1,2). Drugs such as daunomycin, methotrexate, and a GnRH analog coupled either to monoclonal antibodies or to synthetic linear or branched polypeptides... [Pg.209]
