A key determinant in T cell epitope immunogenicity is the binding strength of T cell epitopes to major histocompatibility complexes (MHC or HLA) molecules. Likewise, T Cell epitopes can cause unwanted immunogenicity, including the development of ADAs. T cell epitope content is one of the factors that contributes to antigenicity.
Many lipids and nucleic acids are relatively small molecules and/or have non-immunogenic properties. Therefore, as stated by the World Health Organization, immunogenicity should be investigated in a target population since animal testing and in vitro models cannot precisely predict immune response in humans. Another challenge is considering how the immunogenicity of vaccines changes with age. For example, immunogenicity data from high-income countries are not always transferable to low-income and middle-income countries. Ī challenge in biotherapy is predicting the immunogenic potential of novel protein therapeutics. This reaction leads to production of anti-drug-antibodies (ADAs), inactivating the therapeutic effects of the treatment and potentially inducing adverse effects. Unwanted immunogenicity is an immune response by an organism against a therapeutic antigen.Immunogenicity is a central aspect of vaccine development. Wanted immunogenicity typically relates to vaccines, where the injection of an antigen (the vaccine) provokes an immune response against the pathogen, protecting the organism from future exposure.Immunogenicity is the ability of a foreign substance, such as an antigen, to provoke an immune response in the body of a human or other animal. It has been suggested that Antigenicity be merged into this article.
