Systems integration of innate and adaptive immunity

Area of Science:

• * Immunology
• * Vaccinology
• * Computational Biology

Background:

• * Classical vaccination approaches are insufficient for complex pathogens like those causing AIDS, malaria, and tuberculosis.
• * Human immunology and pathogen-induced immune modulation necessitate novel vaccine discovery strategies.
• * Systems vaccinology integrates holistic analysis of immunity with quantitative frameworks for rational vaccine design.

Purpose of the Study:

• * To introduce systems vaccinology as a novel approach for rational vaccine design.
• * To highlight the importance of integrating innate and adaptive immune responses with vaccine efficacy.
• * To discuss the application of systems vaccinology in vaccine development for complex diseases.

Main Methods:

• * Holistic analysis of innate and adaptive immunity within a quantitative framework.
• * Identifying relationships between early innate inflammatory responses and subsequent adaptive immunity and efficacy.
• * Utilizing peripheral blood transcriptomes as surrogates for inaccessibility of tissue compartments.
• * Integrating immune responses with vaccine efficacy data from clinical studies and challenge models.

Main Results:

• * Blood transcriptomes provide valuable insights in systems vaccinology studies.
• * The approach is most powerful when integrating immune responses with vaccine efficacy, demonstrated in malaria models.
• * Challenges in applying systems vaccinology to AIDS and tuberculosis due to lack of challenge models and variable efficacy.

Conclusions:

• * Systems vaccinology enables the rational design of vaccines eliciting tailored protective immune responses.
• * Iterative application of systems vaccinology, involving hypothesis testing in model systems, guides new vaccine strategies.
• * Adapting clinical trial design and analyzing natural infection cohorts can address challenges in complex diseases.
