Abstract
BACKGROUND Filamentous hemagglutinin (FHA) is a principal virulence factor, an important immunogenic antigen of Bordetella pertussis, and a major component of many acellular pertussis vaccines. In the present study, the human antibody response to different regions of FHA was determined in healthy children and adults vaccinated with either whole-cell or acellular pertussis vaccines. METHODS To define the immunodominant regions of FHA, four overlapping recombinant fragments were expressed and produced in Escherichia coli and then purified by His-tagged based affinity chromatography. Two groups comprising healthy preschool children (n = 50) and adults (n = 26) were vaccinated with a single dose of commercial whole-cell and acellular DTaP vaccines, respectively. An antigen-based ELISA was applied to measure serum levels of anti-FHA antibody to both native and recombinant proteins in vaccinated volunteers. RESULTS In both groups of vaccinated individuals, the anti-FHA antibody response was mainly directed against epitopes located within a fragment of FHA spanning amino acid residues 1877-2250 of the mature FHA molecule (p < 0.001). No or little antibody was detected against the other recombinant segments of FHA. CONCLUSION Our results suggest that the human antibody response to FHA is directed to an immunodominant region located within residues 1877-2250 of the FHA molecule. Characterization and epitope mapping of the major components of acellular pertussis vaccine and future modifications in vaccine formulation may improve its efficacy and protectivity.

Abstract
Filamentous hemagglutinin (FHA) is a major adhesion and virulence factor of Bordetella pertussis and also a main component of acellular pertussis vaccines. Interaction of FHA with different receptors on human epithelial and immune cells facilitates entrance and colonization of bacteria as well as immunomodulation of the host immune response. Three overlapping segments of the FHA gene were cloned in a prokaryotic expression vector and the recombinant proteins were purified. These recombinant fragments along with the native FHA protein were employed to assess their potential Toll-like receptor (TLR) stimulatory effects and to localize the TLR binding region. TLR stimulation was monitored by applying HEK293-Blue cell lines cotransfected with TLR2, 4, or 5 and a NF-κB reporter gene. Culture supernatants were checked for secretion of the reporter gene product and IL-8 as indicators of TLR stimulation. Native FHA was found to strongly stimulate TLR2, but not TLR4 or TLR5 transfected cells. Among recombinant FHA fragments only the fragment spanning amino acid residues 1544-1917 was able to exhibit the TLR2 stimulating property of FHA. Interaction of FHA with TLR2 suggests its involvement in induction of the innate immune system against Bordetella pertussis. The TLR2-binding domain of FHA may contribute to immunoprotection against pertussis infection.

Abstract
BACKGROUND Filamentous hemagglutinin (FHA) is one of the most important immunoprotective antigens of Bordetella pertussis (B. pertussis) and a major component of the acellular pertussis vaccine. In the present study, three overlapping recombinant fragments from the immunodominant region of FHA were produced and their immunogenicity was investigated. METHODS Three overlapping coding sequences of FHA antigen were amplified from B. pertussis genomic DNA by PCR. Amplified fragments were expressed in Escherichia coli (E. coli) BL21(DE3) strain and purified through His-tag using Nickel-based chromatography. Purified fragments were characterized by SDS-PAGE and Western blotting techniques. In vitro peripheral blood mononuclear cells (PBMC) proliferation and IFN-γ production were assessed in a limited number of healthy adults vaccinated with a commercial acellular pertussis vaccine in response to all purified FHA fragments by H3-Thymidine incorporation and ELISA, respectively. RESULTS Recombinant FHA segments were successfully cloned and produced at high levels in E. coli BL21(DE3). SDS-PAGE and Western blot analyses confirmed their purity and reactivity. All three recombinant fragments together with a commercial native FHA were able to induce in vitro PBMC proliferation and IFN-γ production. CONCLUSION Our preliminary results suggest that these overlapping recombinant FHA fragments are immunogenic and may prove to be immuno-protective.

Abstract
Mutants of pertussis toxin (PT) S1 subunit and filamentous hemagglutinin (FHA) type I immunodominant domain from Bordetella pertussis (B. pertussis) are considered to be effective candidate antigens for acellular pertussis vaccines; however, the substantial progress is hampered in part for the lack of a suitable in vitro expression system. In this paper, the gene sequences of a S1 mutant C180-R9K/E129G (mS1) and a truncated peptide named Fs from FHA type I immunodominant domain were linked together and constructed to pET22b expression vector as a fusion gene; after inducing with IPTG, it was highly expressed in E. coli BL21 (DE3) as inclusion body. The fusion protein FsmS1 was purified from cell lysates and refolded successfully. The result of Western blotting indicate that it was able to react with both anti-S1 and anti-FHA McAbs; antiserum produced from New Zealand white rabbits immunized with this protein was able to recognize both native PT and FHA antigens as determined by western blotting. These data have provided a novel feasible method to produce PT S1 subunit and FHA type I immunodominant domain in large scale in vitro, which is implicated for the development of multivalent subunit vaccines candidate against B. pertussis infection.

Abstract
Bacteria of the Bordetella genus cause respiratory tract infections. Both broad host range (e.g. Bordetella bronchiseptica) and human-adapted (e.g. Bordetella pertussis) strains produce a surface-exposed and secreted protein called filamentous haemagglutinin (FHA) that functions in adherence and immunomodulation. Previous studies using B. pertussis and cultured mammalian cells identified several FHA domains with potential roles in host cell interactions, including an Arg-Gly-Asp (RGD) triplet that was reported to bind integrins on epithelial cells and monocytes to activate host signalling pathways. We show here that, in contrast to our previous report, the fhaB genes of B. pertussis and B. bronchiseptica are functionally interchangeable, at least with regard to the various in vitro and in vivo assays investigated. This result is significant because it indicates that information obtained studying FHA using B. bronchiseptica and natural-host animal models should apply to B. pertussis FHA as well. We also show that the C-terminus of mature FHA, which we name the MCD, mediates adherence to epithelial and macrophage-like cells and is required for colonization of the rat respiratory tract and modulation of the inflammatory response in mouse lungs. We could not, however, detect a role for the RGD in any of these processes.

Abstract
Bordetella bronchiseptica is a Gram-negative respiratory pathogen that causes substantial disease in a variety of animals. Filamentous hemagglutinin (FHA) and pertactin are important attachment factors and protective immunogens, which serve as protective antigens in several animal models of infection with B. bronchiseptica. Here, we showed the efficacy of subcutaneous immunization of mice with a recombinant protein rF1P2, which consisted of the important immunodominant protective type I domain (F1) of FHA and the highly immunogenic region II domain (P2) of pertactin. Groups of mice tested, when challenged with different strains of B. bronchiseptica were fully protected, with long-lasting immunity to lethal B.bronchiseptica challenge, whereas mice immunized with Freund's adjuvant alone or PBS were not. In rF1P2-immunized mice, specific antibodies lasted for more than 120 days, and the IgG1/IgG2a ratio remained at a constant level till the end of the study. This suggests that rF1P2-induced a long-lasting balanced humoral immune responses and immunological memory in mice. rF1P2-specific antisera inhibited hemagglutination associated with full-length mature FHA. Furthermore, passive antiserum transfer from immunized animals completely protected naive mice from subsequent B. bronchiseptica challenge. These data may have implications for the development of safe and efficacious subunit vaccines for the prevention of bordetellosis, and may contribute to future acellular whooping cough vaccines.

Abstract
Salmonella enterica serovar Choleraesuis strain C500 is a live, attenuated vaccine that has been used in China for over 40 years to prevent piglet paratyphoid. We compared the protective efficacies of subcutaneous (s.c.) and oral vaccination of BALB/c mice with C500 expressing the recombinant filamentous hemagglutinin type I domain and pertactin region 2 domain antigen (rF1P2) of Bordetella bronchiseptica. Protective efficacy against both S. enterica serovar Choleraesuis infection in an oral fatal challenge model and B. bronchiseptica infection in a model of fatal acute pneumonia was evaluated. Both the s.c. and oral vaccines conferred complete protection against fatal infection with the virulent parent S. enterica serovar Choleraesuis strain (C78-1). All 20 mice vaccinated s.c. survived intranasal challenge with four times the 50% lethal dose of virulent B. bronchiseptica (HH0809) compared with 4 of 20 vector-treated controls and 1 of 18 phosphate-buffered saline-treated controls that survived, but no significant protection against HH0809 was observed in orally vaccinated animals. Both the s.c. and oral vaccines elicited rF1P2-specific serum immunoglobulin G (IgG) and IgA antibodies. However, lung homogenates from s.c. vaccinated animals had detectably high levels of rF1P2-specific IgG and IgA; a much lower level of rF1P2-specific IgG was detected in samples from orally vaccinated mice, and the latter showed no evidence of local IgA. Furthermore, a more abundant and longer persistence of vaccine organisms was observed in the lungs of mice immunized s.c. than in those of mice immunized orally. Our results suggest that s.c. rather than oral vaccination is more efficacious in protecting mice from fatal challenge with B. bronchiseptica.

Abstract
While evaluating vaccine efficacy against clinical Bordetella pertussis isolates in mice, after challenge vaccinated mice showed increased lung pathology with eosinophilia, compared to challenged, non-vaccinated animals. This led us to study bacterial clearance, lung pathology, lung TNF-alpha expression, and parameters of immediate hypersensitivity (IH), being serum IgE levels, eosinophil numbers in the bronchoalveolar lavage fluid, and ex vivo IL-4, IL-5, IL-10, IL-13, and IFN-gamma production by the bronchial lymph node cells. BALB/c mice received a combined Diphtheria (D), Tetanus (T), Poliomyelitis, and whole-cell Pertussis vaccine (WCV), a combined D, T, and three-component acellular Pertussis vaccine (ACV), aluminium hydroxide adjuvant, or PBS, 28 and 14 days before B. pertussis infection. Similarly treated non-infected mice were taken as a control. Infection induced pathology; this induction was stronger after (especially WCV) vaccination. WCV but not ACV vaccination induced TNF-alpha expression after challenge. After challenge, IH parameters were strongly increased by (especially ACV) vaccination. Vaccinated IL-4 KO mice showed similar clearance and pathology, in the absence of IgE and with reduced numbers of eosinophils. Vaccinated (Th1-deficient) T-bet KO mice showed reduced clearance and similar pathology. In summary, after challenge vaccination increased lung pathology, TNF-alpha expression (only WCV), and IH parameters. Th1 cells were critical for clearance.

Abstract
Filamentous haemagglutinin adhesin (FHA) is an important virulence factor from Bordetella pertussis related to the adhesion and spread of the bacteria through the respiratory tract. Three distinct domains have been characterized in mature FHA, and among them, the FHA(442-863) fragment was suggested to be responsible for the heparin-binding activity. In this study, we cloned the gene encoding the HEP fragment (FHA(430-873)) in a Lactobacillus casei-inducible expression vector based on the lactose operon. The recombinant bacteria, transformed with the resulting construct (L. casei-HEP), were able to express the heterologous protein depending on the sugar added to the culture. Subcutaneous inoculation of L. casei-HEP in Balb/C mice, using the cholera toxin B subunit as adjuvant, induced systemic anti-HEP antibodies that were able to inhibit in vitro erythrocyte haemagglutination induced by FHA. This is the first example of a B. pertussis antigen produced in lactic acid bacteria and opens new perspectives for alternative vaccine strategies against whooping cough.

Abstract
Filamentous hemagglutinin adhesin (FHA) is important for the adherence of Bordetella pertussis to the host ciliary epithelial cells of the respiratory tract. Several binding domains have been characterized in the FHA molecule. For example, an putative heparin-binding domain of FHA was previously located in the FHA(442-863) region. In this work, the HEP fragment, corresponding to FHA(430-873) was amplified by PCR and subcloned in an Escherichia coli expression plasmid. Purified recombinant HEP was used to produce polyclonal antibodies in mice that were able to recognize HEP and FHA in ELISA and in Western-blot assays. Although recombinant HEP displayed low ability to bind heparin and no hemagglutination activity, the anti-HEP antibodies were able to inhibit FHA mediated hemagglutination activity in goose erythrocytes. These results indicate that other amino acid residues that are not present in the FHA(430-873) fragment may be necessary for heparin binding. Further studies to address the immunogenic response against HEP are also required.

We have developed a large phagemid display library (approximately 7.7x10(7) independent clones) of sheared S. cerevisiae genomic DNA (12.1 Mbp genome size) fused to gene III (lacking the N1 domain) of the filamentous phage M13. Baits tagged with an N-terminal E-tag and a C-terminal His(6)-tag are prepared in a novel Escherichia coli expression system. Using E-Gal80-His(6) as bait, biopanning of the library resulted in the isolation of two different clones containing fragments of the known interacting partner Gal4p. In addition, three new ligands (Ubr1p, YCL045c and Prp8p) with potential physiological relevance were isolated. Interactions were confirmed by ELISA. These results demonstrate the accessibility of the S. cerevisiae genome to display technology for protein-protein interaction screening.

Abstract
Bordetella pertussis, the etiological agent of whooping cough, produces a number of factors, such as toxins and adhesins, that are required for full expression of virulence. Filamentous hemagglutinin (FHA) is the major adhesin of B. pertussis. It is a protein of approximately 220 kDa, found both associated at the bacterial cell surface and secreted into the extracellular milieu. Despite its importance in B. pertussis pathogenesis and its inclusion in most acellular pertussis vaccines, little is known about the functional importance of individual domains in infection and in the induction of protective immunity. In this study, we analyzed the role of the approximately 80-kDa N-terminal domain of FHA, designated Fha44, in B. pertussis adherence, colonization, and immunogenicity. Although Fha44 contains the complete heparan sulfate-binding domain, it is not sufficient for adherence to epithelial cells or macrophages. It also cannot replace FHA during colonization of the mouse respiratory tract. Infection with a B. pertussis strain producing Fha44 instead of FHA does not induce anti-FHA antibodies, whereas such antibodies can readily be induced by intranasal administration of purified Fha44. In addition, mice immunized with purified Fha44 were protected against challenge with wild-type B. pertussis, indicating that Fha44 contains protective epitopes. Compared to FHA, Fha44 is much smaller and much more soluble and is therefore easier to purify and to store. These advantages may perhaps warrant considering Fha44 for inclusion in acellular pertussis vaccines.

Abstract
Phage display has emerged as a powerful technique for mapping epitopes recognised by monoclonal and polyclonal antibodies. We have recently developed a simple gene-fragment phage display system and have shown its utility in mapping epitope recognised by a monoclonal antibody. In the present study, we have employed this system in mapping epitopes recognised by polyclonal antibodies raised against HIV-1 capsid protein, p24 which is derived from proteolytic cleavage of Gag polyprotein. HIV-1 gag DNA was fragmented by DNase I and the fragments (50-250 bp) were cloned into gene-fragment phage display vector to construct a library of phages displaying peptides. This phage library was used for affinity selection of phages displaying epitopes recognised by rabbit anti-p24 polyclonal antibodies. Selected phages contained sequences from two discrete regions of p24, demonstrating the presence of two antigenic regions. The DNA sequences encoding these regions were also cloned and expressed as GST fusion proteins. The immunoreactivity of these epitopes as GST fusion proteins, or as phage-displayed peptides, was comparable in ELISA system using same anti-p24 polyclonal antibodies. The results indicate that the gene-fragment based phage display system can be used efficiently to identify epitopes recognised by polyclonal antibodies, and phage displayed epitopes can be directly employed in ELISA to detect antibodies.

Abstract
Two closely related pathogens, Bordetella pertussis and Bordetella bronchiseptica, share a number of virulence factors. Filamentous haemagglutinin (FHA) is widely regarded as the dominant adhesin of B. pertussis, and its multiple binding activities have been well characterized. This large protein is produced and secreted at high levels by B. pertussis and significantly lower levels by B. bronchiseptica strains. FHA secretion is mediated by a single outer-membrane accessory protein, FhaC. The genes encoding FHA and FhaC in B. bronchiseptica were characterized by sequencing and functional analyses and are highly similar to those of B. pertussis. The most distinctive feature of B. bronchiseptica FHA is additional repeats in the N-terminal portion of the predicted protein. Interestingly, a point mutation in the fhaB promoter region of the B. bronchiseptica GP1 isolate, relative to other isolates, was found to be detrimental to promoter activity and to FHA production. FhaC and the N-terminal secretion domain of FHA of B. bronchiseptica were fully functional for secretion in B. pertussis. Thus, the different levels of FHA secretion by these Bordetella species might reflect differences in physiology, composition and structure of cell envelope, or differential protein degradation. Characterization of FHA expression and function may provide clues as to the basis of host species tropism, tissue localization and receptor recognition.

Abstract
Filamentous hemagglutinin (FHA) is an outer-membrane associated adhesin conserved within the genus Bordetella. FHA provides protection against B. pertussis infections in humans and is a component of acellular whooping cough vaccines. Furthermore, FHA serves as a protective antigen in several animal models of infection with B. bronchiseptica and may serve as a protective antigen of canine bordetellosis. In this study, polyclonal anti-B. pertussis FHA antiserum was used to identify an immunoreactive clone from the genomic DNA library of a canine B. bronchiseptica field isolate. The nucleotide and predicted amino acid sequences of the immunoreactive clone were compared to fhaB and FhaB from B. pertussis revealing 94% identity at the nucleic acid level, and 86% identity at the protein level. A truncated fusion protein (FHAt) was prepared which included a conserved domain homologous to the immunodominant region in the FHA of B. pertussis [Leininger E, Bowen S, Renauld-Mongen G, Rouse JH, Menozzi FD, Locht C, Heron I, Brennan MJ. Immunodominant domain present on the Bordetella pertussis vaccine component filamentous hemagglutinin. J. Infect. Dis. 1997;175:1423-1431; Wilson DR, Siebers A, Finlay BB. Antigenic analysis of Bordetella pertussis filamentous hemagglutinin with phage display libraries and rabbit anti-filamentous hemagglutinin polyclonal antibodies. Infect. Immun. 1998;66:4884-4894]. FHAt was shown to be safe and antigenic in rabbits. FHAt induced the formation of antibodies that inhibit the hemagglutination associated with full length B. pertussis FHA, and inhibit adherence of B. bronchisepitca to canine fibroblasts by as much as 65%. This information may have implications for the development of safe and efficacious subunit vaccines for the prevention of canine bordetellosis and may contribute to future acellular whooping cough vaccines.
