Immunizing mice with vaccine targets and further optimization
An animal model's ability to reproduce relevant human physiology determines its utility and appropriateness for vaccine development. Good animal models share the same physiological characteristics as humans or reflect them as closely as possible. Using preclinical animal models that express the required receptors for a specific pathogen—or natural disease models with pathology comparable to the human disease—remains critical prior to vaccine testing in humans.
Typically, natural or surrogate animal models are used for vaccine development. Natural disease models have the advantage of modeling the interaction between host and pathogen within the appropriate biological context and make use of a specific pathogen and its natural host. Surrogate models refer to the use of species that can only be infected with the pathogen of interest under experimental conditions. Compromises such as higher infection doses or artificial routes of infection often have to be made with surrogate models, but they have provided a useful tool for studying specific aspects of either disease pathogenesis or the host's immune response. In most cases, mice are the animal species of choice. Mouse models offer the advantage of working in a consistent genetic background, are easy to handle, and are relatively cost effective (Gerdts et al. 2007).
Takara Bio's SMARTer Mouse BCR and TCR profiling kits help speed up the process of immune sera screening of mice for antiviral activity of target vaccines by monitoring vaccine-specific changes in the BCR and TCR clonotype repertoires as a proxy for an efficient immune response to the vaccine challenge. Promising vaccine candidates are further optimized by analyzing and comparing antibody and T-cell responses in the vaccinated animals prior to and upon exposure to the virus.

- Complete V(D)J sequence information—obtain full-length sequences for variable regions of TCR mRNA transcripts
- TCR-alpha and TCR-beta—profile diversity for both TCR subunits, either in the same experiment or separately
- No multiplex PCR required—amplify sequences for each TCR subunit with a single primer pair per reaction
- Illumina-ready sequencing libraries—incorporate Illumina adapter and index sequences in a ligation-independent manner, and multiplex up to 96 libraries in a single flow-cell lane
Numerous laboratories have already used SMARTer BCR and TCR profiling kits for their vaccine development research:
