background: the major problem of dna vaccine is less immunogenicity of them verses other killed or live whole organism vaccines therefore adjuvants for use in this kind vaccines is very necessary. genetic adjuvants with bacterial sources are an appropriate approach to modulate immune responses to dna vaccines. listeria monocytogenes proteins such as listeriolysin o (llo) with cd4 and cd8 epitop...
In this study, the role of Listeria monocytogenes ferritin was investigated. The fri gene encoding the ferritin was deleted and the phenotype of the mutant was analyzed demonstrating that ferritin is necessary for optimal growth in minimal medium in both presence and absence of iron, as well as after cold- and heat-shock. We also showed that ferritin provides protection against reactive oxygen ...
Listeriolysin O (LLO) is a thiol-activated cytolysin secreted by Listeria monocytogenes. LLO and phosphatidylinositol phospholipase C are two essential virulence factors, which this bacterium needs to escape from the phagosomal compartment to the cytoplasm. Cathepsin-D specifically cleaves LLO, between the Trp-491 (tryptophan amino acid in three letter nomenclature) and Trp-492 residues of the ...
