Název v původním jazyce

Francisella tularensis type B Delta dsbA mutant protects against type A strain and induces strong inflammatory cytokine and Th1-like antibody response in vivo

Popis výsledku v původním jazyce

Francisella tularensis subspecies tularensis is a highly virulent intracellular bacterial pathogen, causing the disease tularemia. However, a safe and effective vaccine for routine application against F. tularensis has not yet been developed. We have recently constructed the deletion mutants for the DsbA homolog protein (Delta dsbA/FSC200) and a hypothetical protein IglH (Delta iglH/FSC200) in the type B F. tularensis subsp. holarctica FSC200 strain, which exerted different protection capacity against parental virulent strain. In this study, we further investigated the immunological correlates for these different levels of protection provided by Delta dsbA/FSC200 and Delta iglH/FSC200 mutants. Our results show that Delta dsbA/FSC200 mutant, but not Delta iglH/FSC200 mutant, induces an early innate inflammatory response leading to strong Th1-like antibody response. Furthermore, vaccination with Delta dsbA/FSC200 mutant, but not with Delta iglH/FSC200, elicited protection against the sub
