Bordetella pertussis vaccine composition drives hematopoietic stem and progenitor cell expansion and immune response during vaccination and subsequent challenge.
Abstract:Pertussis is a re-emerging infectious disease world-wide. It is hypothesized that current acellular vaccines (ACVs) wane in efficacy each year after immunization. We hypothesized that whole cell vaccines (WCVs) induce hematopoietic stem and progenitor cell (HSPC) expansion and differentiation processes necessary for life-long protection. While HSPC innate immune signaling and expansion play a critical role in directing immune response to infection, their role in vaccine efficacy is unclear. To test our hypothe… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
