Molecular and cellular dynamics in the skin, the lymph nodes and the blood of the immune response to intradermal injection of Modified Vaccinia Ankara vaccine
Ontology highlight
ABSTRACT: New vaccine design approaches would be greatly facilitated by a better understanding of the early systemic changes, and those that occur at the site of injection, responsible for the installation of a durable and oriented protective response. We performed a detailed characterization of very early infection and host response events following the intradermal administration of the modified vaccinia virus Ankara attenuated vaccine in non-human primates. Integrated analysis of the data obtained from in vivo imaging, histology, flow cytometry, multiplex cytokine, and transcriptomic analysis using tools derived from systems biology, such as correlation networks, showed a strong early local and systemic inflammatory response that peaked at 24 h, which was then progressively replaced by an adaptive response during the installation of the host response to the vaccine. Such comprehensive approaches should improve our understanding of how to effectively orientate the immune response, and could contribute to rational vaccine development.
