Pertussis toxin is the preeminent virulence factor and major protective antigen produced by Bordetella pertussis, the human respiratory pathogen and etiologic agent of whooping cough. Genes for its synthesis and export are encoded by the 12 kb ptx-pt

Summary A prominent feature of the promoters of Bordetella pertussis fimbrial subunit genes fim2, fim3 and fimX is the presence of a ‘C-stretch’, a monotonic run of C residues. The C-stretch renders these genes capable of phase variation, through

Summary To investigate the mechanism by which the Bordetella BvgAS phosphorelay controls expression of at least three distinct phenotypic phases, we isolated and characterized two B. pertussis mutants that were able to express Bvg - and Bvg i phase p

The Bordetella bipA gene is expressed maximally when the BvgAS phosphorelay is semi-active, i.e. in the Bvg-intermediate (Bvg(i)) phase. We used a BvgA-FeBABE cleavage approach together with site-directed mutagenesis and bipA-lacZ fusion analyses to

In order to define a consensus binding sequence for the response regulator BvgA, we have undertaken a systematic analysis of contributions made by each nucleotide within the heptad half-sites that are present in an inverted orientation at the promote

The BvgA-BvgS two-component signal transduction system regulates expression of virulence factors in Bordetella pertussis . The BvgA response regulator activates transcription by binding to target promoters, which include those for the genes encoding

Bordetella pertussis , the causative agent of whooping cough, regulates expression of its virulence factors via a two-component signal transduction system encoded by the bvg regulatory locus. It has been shown by activation kinetics that several of t

Heat shock proteins (HSPs) derived from tumors or virally infected cells can stimulate antigen-specific CD8+ T cell responses in vitro and in vivo. Although this antigenicity is known to arise from HSP-associated peptides presented to the immune syst

The expression of virulence factor genes in Bordetella pertussis is mediated by the BvgA-BvgS two-component signal transduction system. The response regulator, BvgA, acts directly as a transcriptional activator at the loci encoding pertussis toxin (p

Bordetella pertussis BvgA is a global response regulator that activates virulence genes, including adhesin-encoding fim3 and fhaB. At the fhaB promoter, P(fhaB), a BvgA binding site lies immediately upstream of the -35 promoter element recognized by
