Abstract
Influenza viruses are a major public health problem. Vaccines are the best available countermeasure to induce effective immunity against infection with seasonal influenza viruses; however, the breadth of antibody responses in infection versus vaccination is quite different. Here, we show that nasal infection controls two sequential processes to induce neutralizing IgG antibodies recognizing the hemagglutinin (HA) of heterotypic strains. The first is viral replication in the lung, which facilitates exposure of shared epitopes that are otherwise hidden from the immune system. The second process is the germinal center (GC) response, in particular, IL-4 derived from follicular helper T cells has an essential role in the expansion of rare GC-B cells recognizing the shared epitopes. Therefore, the combination of exposure of the shared epitopes and efficient proliferation of GC-B cells is critical for generating broadly-protective antibodies. These observations provide insight into mechanisms promoting broad protection from virus infection. The reasons why influenza infection promotes a broader antibody response compared with vaccines are not fully understood. Here the authors show that unmasking of haemagglutinin epitopes and IL-4 signals in the germinal centre contribute to broader antibody responses after infection.

Abstract
Influenza A virus infections are a global health threat to humans and are endemic in pigs, contributing to decreased weight gain and suboptimal reproductive performance. Pigs are also a source of new viruses of mixed swine, avian, and human origin, potentially capable of initiating human pandemics. Current inactivated vaccines induce neutralising antibody against the immunising strain but rapid escape occurs through antigenic drift of the surface glycoproteins. However, it is known that prior infection provides a degree of cross-protective immunity mediated by cellular immune mechanisms directed at the more conserved internal viral proteins. Here we review new data that emphasises the importance of local immunity in cross-protection and the role of the recently defined tissue-resident memory T cells, as well as locally-produced, and sometimes cross-reactive, antibody. Optimal induction of local immunity may require aerosol delivery of live vaccines, but it remains unclear how long protective local immunity persists. Nevertheless, a universal vaccine might be extremely useful for disease prevention in the face of a pandemic. As a natural host for influenza A viruses, pigs are both a target for a universal vaccine and an excellent model for developing human influenza vaccines.

Antigenic Fingerprinting following Primary RSV Infection in Young Children Identifies Novel Antigenic Sites and Reveals Unlinked Evolution of Human Antibody Repertoires to Fusion and Attachment Glycoproteins. PLoS Pathog 2016; 12:e1005554. [PMID: 27100289 PMCID: PMC4839671 DOI: 10.1371/journal.ppat.1005554] [Citation(s) in RCA: 56] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2015] [Accepted: 03/14/2016] [Indexed: 11/24/2022] Open
Abstract
Respiratory Syncytial Virus (RSV) is the major cause of pneumonia among infants. Here we elucidated the antibody repertoire following primary RSV infection and traced its evolution through adolescence and adulthood. Whole genome-fragment phage display libraries (GFPDL) expressing linear and conformational epitopes in the RSV fusion protein (F) and attachment protein (G) were used for unbiased epitope profiling of infant sera prior to and following RSV infection. F-GFPDL analyses demonstrated modest changes in the anti-F epitope repertoires post-RSV infection, while G-GFPDL analyses revealed 100-fold increase in number of bound phages. The G-reactive epitopes spanned the N- and C-terminus of the G ectodomain, along with increased reactivity to the central conserved domain (CCD). Panels of F and G antigenic sites were synthesized to evaluate sera from young children (<2 yr), adolescents (14–18 yr) and adults (30–45 yr) in SPR real-time kinetics assays. A steady increase in RSV-F epitope repertoires from young children to adults was observed using peptides and F proteins. Importantly, several novel epitopes were identified in pre-fusion F and an immunodominant epitope in the F-p27. In all age groups, antibody binding to pre-fusion F was 2–3 folds higher than to post-fusion form. For RSV-G, antibody responses were high following early RSV infection in children, but declined significantly in adults, using either G proteins or peptides. This study identified unlinked evolution of anti-F and anti G responses and supportive evidence for immune pressure driven evolution of RSV-G. These findings could help development of effective countermeasures including vaccines. Respiratory syncytial virus (RSV) is the major cause of pneumonia and bronchiolitis among infants and children globally. In the United States, RSV infections lead to 57,000 hospitalizations among young children, especially in those less than one year old. Furthermore, despite the development of immunity following RSV infection during childhood, individuals remain susceptible to RSV upper respiratory tract reinfection. In the current study we explored the antibody repertoires following primary RSV infection and their evolution in adolescents and adults. Whole genome-fragment phage display libraries (GFPDL) expressing linear and conformational epitopes from RSV fusion protein (F) and attachment protein (G) were used for unbiased epitope profiling of sera prior to and following RSV infection. In addition, Plasmon Surface Resonance (SPR) was used to measure antibody binding to F and G peptides and proteins. A steady increase in RSV-F epitope repertoires from young children to adults was observed. Several novel epitopes were identified in pre-fusion F and an immunodominant epitope in F0-p27. For RSV-G, antibody responses were high following RSV infection in children, but declined in adults. This study identified unlinked evolution of anti-F and anti G responses that could help development of better RSV vaccines and therapies.

PLoS One 2015; 10:e0115476.

Abstract
A Phase I trial conducted in 2009-2010 demonstrated that oral vaccination with a replication competent Ad4-H5 (A/Vietnam) vector with dosages ranging from 107-1011 viral particles was well tolerated. HA-specific T-cell responses were efficiently induced, but very limited hemagglutination-inhibiting (HI) humoral responses were measured. However, a single boost of Ad4-H5-Vtn vaccinated individuals with a unadjuvanted licensed H5N1 (A/Vietnam) subunit vaccine resulted in superior HI titers compared with unprimed subjects. In the current study, the impact of Ad4-H5 priming on the quality of the polyclonal humoral immune response was evaluated using a real-time kinetics assay by surface plasmon resonance (SPR). Total binding of serum polyclonal antibodies from the Ad4-H5-Vtn primed groups against both homologous H5N1-A/Vietnam/1194/2004 (clade 1) and heterologous A/Indonesia-5/2005 (clade 2.1) HA1 head domain was significantly higher compared with sera from individuals that received subunit H5N1 vaccination alone. SPR measurements also demonstrated that the antigen-antibody complex dissociation rates (a surrogate for antibody affinity) of serum antibodies against the HA1 of H5N1-A/Vietnam were significantly higher in the Ad4-H5 primed groups compared with those from the unprimed group. Furthermore, strong correlations were observed between the antibody affinities for HA1 (but not HA2) and the virus neutralization titers against the homologous strain and a panel of heterologous clade 2 H5N1 strains. These findings support the concept of oral prime-boost vaccine approaches against pandemic influenza to elicit long-term memory B cells with high affinity capable of rapid response to variant pandemic viruses likely to emerge and adapt to human transmissions.

Heterologous prime-boost vaccination with MF59-adjuvanted H5 vaccines promotes antibody affinity maturation towards the hemagglutinin HA1 domain and broad H5N1 cross-clade neutralization. PLoS One 2014; 9:e95496.

Abstract
In an open label clinical study (2007), MF59-adjuvanted hemagglutinin (HA) vaccine from H5N1-A/Vietnam/1194/2004 (clade 1) was administered to subjects previously vaccinated (primed) with clade 0 H5N3 (A/duck/Singapore/97) vaccine at least 6 years earlier (in 1999 or 2001). The primed individuals responded rapidly and generated high neutralizing antibody titers against the H5N1-Vietnam strain within 7 days of a single booster vaccination. Furthermore, significant cross-neutralization titers were measured against H5N1 clade 0, 1, and 2 viruses. In the current study, the impact of MF59 adjuvant during heterologous priming on the quality of humoral polyclonal immune response in different vaccine arms were further evaluated using real time kinetics assay by surface plasmon resonance (SPR). Total anti-H5N1 HA1 polyclonal sera antibody binding from the heterologous prime-boost groups after a single MF59-H5N1 boost was significantly higher compared with sera from unprimed individuals that received two MF59-H5N1 vaccinations. The antigen-antibody complex dissociation rates (surrogate for antibody affinity) of the polyclonal sera against HA1 of H5N1-A/Vietnam/1194/2004 from the MF59-H5N3 primed groups were significantly higher compared to sera from unadjuvanted primed groups or unprimed individuals that received two MF59-H5N1 vaccines. Furthermore, strong inverse correlations were observed between the antibody dissociation off-rates of the immune sera against HA1 (but not HA2) and the virus neutralization titers against H5 vaccine strains and heterologous H5N1 strains. These findings supports the use of oil-in-water-adjuvanted pandemic influenza vaccines to elicit long term memory B cells with high affinity BCR capable of responding to potential variant pandemic viruses likely to emerge and adapt to human transmissions.

Antigen-specific B-cell receptor sensitizes B cells to infection by influenza virus. Nature 2013; 503:406-9.

Abstract
Influenza A virus-specific B lymphocytes and the antibodies they produce protect against infection. However, the outcome of interactions between an influenza haemagglutinin-specific B cell via its receptor (BCR) and virus is unclear. Through somatic cell nuclear transfer we generated mice that harbour B cells with a BCR specific for the haemagglutinin of influenza A/WSN/33 virus (FluBI mice). Their B cells secrete an immunoglobulin gamma 2b that neutralizes infectious virus. Whereas B cells from FluBI and control mice bind equivalent amounts of virus through interaction of haemagglutinin with surface-disposed sialic acids, the A/WSN/33 virus infects only the haemagglutinin-specific B cells. Mere binding of virus is not sufficient for infection of B cells: this requires interactions of the BCR with haemagglutinin, causing both disruption of antibody secretion and FluBI B-cell death within 18 h. In mice infected with A/WSN/33, lung-resident FluBI B cells are infected by the virus, thus delaying the onset of protective antibody release into the lungs, whereas FluBI cells in the draining lymph node are not infected and proliferate. We propose that influenza targets and kills influenza-specific B cells in the lung, thus allowing the virus to gain purchase before the initiation of an effective adaptive response.

Abstract
Secondary lymphoid organs (SLOs) promote primary immune responses by recruiting naive lymphocytes and activated APCs. However, their role in the persistence or responsiveness of memory lymphocytes is unclear. We tested whether memory cells were maintained and could respond to challenge in the absence of SLOs. We found that influenza-specific CD8 cells in the lung acquired a memory phenotype, underwent homeostatic proliferation, recirculated through nonlymphoid tissues, and responded to and cleared a challenge infection in the complete absence of SLOs. Similarly, influenza-specific virus-neutralizing antibody was generated and maintained in the absence of SLOs. Inducible bronchus-associated lymphoid tissue (iBALT) was also formed in the lungs of previously infected mice and may provide a niche for the maintenance of memory cells at the local level. These data show that SLOs are dispensable for the maintenance of immunologic memory and directly demonstrate the utility of local tissues, such as iBALT, in secondary immune responses.

Abstract
The globular region of hemagglutinin (residues 91-261) membrane glycoprotein of influenza virus that encompasses the binding zone to the oligosaccharide receptor of target cells has been cloned by reverse transcriptase-polymerase chain reaction (RT-PCR). This protein segment (denoted HA91-261 peptide) induced significant immune response in mice. The serum antibodies and lung homogenates from the immunized mice cross-reacted with native virus particles. The cellular immunity was manifested by proliferative splenocyte responses and cytokine release indicating T helper type 1 activity. The plasmid DNA containing this segment (denoted pHA91-261) provoked, in addition, a significant cytotoxic T lymphocyte (CTL) response, whereas the HA91-261 protein fragment led to no such response. Both the DNA and the protein fragment of HA91-261 induced significant protection against viral challenge, although the immune response they induce might be along different pathways. Interestingly, the combined DNA priming-protein boosting immunization regimen did not induce protection against viral challenges even though it led to significant humoral immune responses similar to that induced by the peptide vaccine.

Abstract
How the immune system relates to the boar reproductive tract is not well defined. This is an important area of study because disease-causing agents may be transmitted through boar semen. We have previously identified porcine reproductive and respiratory syndrome virus (PRRSV) in boar semen and wanted to identify PRRSV-specific antibodies within seminal plasma. However, literature documenting total immunoglobulin concentration or the predominant immunoglobulin isotype in boar semen was not available. Therefore, we developed a sandwich enzyme-linked immunoassay (ELISA) to quantitate total IgG, IgA and IgM in seminal plasma from 16 healthy, nonvaccinated, adult boars (n = 102 semen samples). In seminal plasma, IgG was the predominant isotype followed by IgA and IgM. Mean levels +/- the standard deviation followed by the 95% confidence interval of IgG, IgA and IgM were 23.2 +/- 14 microg/mL (15.5 to 31.0), 4.8 +/- 2.5 microg/mL (3.5 to 6.2) and 3.7 +/- 1.7 microg/mL (2.7 to 4.7), respectively. These concentrations of immunoglobulins in seminal plasma were considerably lower than in other swine secretions, which might allow for the survival of infectious agents in boar semen.

Abstract
The effect of endogenous interleukin-12 (IL-12) on the influenza virus immune response in BALB/c mice was evaluated. Following primary influenza virus infection, IL-12 mRNA and protein are detected in the lung, with live virus being required for cytokine induction. Endogenous IL-12 contributes to early NK cell-dependent gamma interferon (IFN-gamma) production (days 3 and 5) but not late T-cell-dependent IFN-gamma secretion (day 7). IL-12 contributes to the inhibition of early virus replication but is not required for virus clearance. IL-12 also modestly contributes to the activation of cytotoxic T lymphocytes. Thus, in this model of experimental influenza virus infection, endogenous IL-12 contributes primarily to the early development and activation of the innate immune response.

Abstract
In comparison to primary immune responses after lung immunization, the level of antigen-specific antibody and the number of cells producing specific antibody are significantly increased after challenging the lungs with antigen. The response of immune memory cells in the lung to an antigen challenge could be responsible for this elevated immune response. However, increased numbers of antibody-producing cells, possibly produced in the lung-associated lymph nodes, are also found in the blood after an antigen challenge. Therefore, it is possible that both the response of immune memory cells in the lung, and the recruitment of antibody-producing cells from the blood, contribute to the elevated levels of antibody in the lung after an antigen challenge. This study compared the level of antibody produced in the lung by the response of pulmonary immune memory cells with the level of antibody produced by antibody-forming cells that enter the lung from blood after an antigen challenge. This comparison was made possible by immunizing and challenging two lung lobes of dogs with two antigens. The immune responses to both antigens were then evaluated in both lung lobes after primary immunization and challenge. Data from these evaluations showed that most antibody in the lung after an antigen challenge is produced by a localized anamnestic response of pulmonary immune memory cells. A significantly lower level of antibody entered the lung from the vasculature and/or was produced by antibody-forming cells that entered the lung from blood after an antigen challenge.

Abstract
Protection of BALB/c (H-2d) mice against secondary challenge with influenza A viruses is primarily dependent on appropriate recognition of the hemagglutinin (HA) molecule by effectors of humoral immunity, the B lymphocytes and their product the immunoglobulin molecules. The influence of the antigenic form of the HA in eliciting protective antibodies is not clearly defined. We directly monitored the kinetics, character, localization, and helper T-cell dependence of the primary antibody-forming cell (AFC) response and the development of B-cell memory in lymphoid tissues associated with the upper and lower respiratory tracts, and in the spleen and bone marrow, to three forms of HA with various degrees of antigenic organization. Our results show that the antigenic organization of HA substantially influences B-cell immunity, namely, the capacity to generate both primary AFCs and memory B cells responsive to lethal challenge. Immunization by infection is the most efficient means of generating protective memory B cells, in contrast to subunit vaccine. The data also indicate that memory AFCs are predominantly localized to the regional lymphoid tissue where challenge HA is found, unlike primary AFCs, which are restricted to the priming site and which require in vivo CD4+ T-cell help.

This study investigated whether a single amino acid change in the hemagglutinin (HA) molecule influenced the efficacy of formalin-inactivated influenza A (H3N1) vaccine candidates derived from high-growth reassortants between the standard donor of high-yield genes (A/PR/8/34 [H1N1]) and host cell variants generated from the same clinical isolate (A/Memphis/7/90 [H3N2]) by passage in embryonated chicken eggs. Two clones of the isolate generated by growth in eggs differed from the parent virus (represented by an MDCK cell-grown counterpart) solely by the presence of Lys (instead of Glu) at position 156 or Ile (instead of Ser) at position 186 in the HA1 subunit. The protective efficacy of egg-grown HA Lys-156 and HA Ile-186 reassortant variants was compared with that of the MDCK cell-grown reassortant vaccine. Classically, antibody titers in serum have been used to demonstrate vaccine efficacy. Here, parameters of B-cell responsiveness were monitored, including the kinetics, character, and localization of the primary antibody-forming cell (AFC) response and the development of B-cell memory in lymphoid tissues associated with the priming site (spleen) and responsive to pulmonary challenge with infectious virus (upper and lower respiratory tract lymph nodes). We show that the egg-grown HA Lys-156 variant induced an AFC profile vastly different from that elicited by the other two reassortant vaccines. The vaccine was poorly immunogenic; it induced antibodies that were cross-reactive prior to challenge but which, postchallenge with a lethal dose of the MDCK cell-grown reassortant virus, were targeted primarily to the HA Lys-156 variant, were of the immunoglobulin M isotype, were nonprotective, and were derived from the spleen. In contrast, the egg-grown HA Ile-186 variant was remarkably like the MDCK cell-grown virus in that protective immunoglobulin G antibodies were unaffected by the Ile-186 substitution but poorly recognized HA with Lys-156. Furthermore, memory AFC responsiveness was localized to regional lymphoid tissue in the upper respiratory tract, where challenge HA was found. Thus, it is recommended that in the selection of vaccine candidates, virus populations with the egg-adapted HA Lys-156 substitution be eliminated and that, instead, egg-grown isolates which minimally contain Ile-186 be used as logical alternatives to MDCK cell-grown viruses.

Abstract
The development of Sendai virus-specific cytotoxic T-lymphocyte (CTL) effectors and precursors (CTLp) has been compared for mice that are homozygous (-/-) for a disruption of the H-2I-Ab class II major histocompatibility complex glycoprotein and for normal (+/+) controls. The generation of CD8+ CTLp was not diminished in the -/- mice, though they failed to make virus-specific immunoglobulin G class antibodies. While the cellularity of the regional lymph nodes was decreased, the inflammatory process assayed by bronchoalveolar lavage (BAL) of the pneumonic lung was not modified, and potent CTL effectors were present in BAL populations recovered from both groups at day 10 after infection. There was little effect on virus clearance. Production of interleukin-2 by both freshly isolated BAL inflammatory cells and cultured lymph node cells was greatly diminished, though the -/- mice still made substantial levels of gamma interferon. However, treating the mice with a single dose of a monoclonal antibody to this cytokine, at least some of which is made by CD8+ T cells, did not decrease CTLp frequencies. As found previously with CD4-depleted H-2b mice, the development of Sendai virus-specific CD8+ T-cell-mediated immunity is not compromised by the absence of a concurrent class II major histocompatibility complex-restricted response.

Abstract
The IgG isotype profile of the influenza virus-specific immune response was studied by quantitation of serum antibody (Ab) levels in correlation with the enumeration of antibody-secreting cells (ASC) detected in the lung, spleen, mediastinal lymph nodes (MLN), Peyer's patches and bone marrow (BM). Distinct isotypic patterns for serum Ab and Ab produced by cells present at or close to the site of infection were found after primary or repeated infections. An elevated number of IgM ASC was found after primary challenge in the spleen, lung and MLN. In contrast, the site of IgA and IgG production is restricted to the lung and lymph nodes draining the site of infection. In these organs IgA, IgG2a and IgG1 ASC are found as a result of primary virus infection while viral challenge induces mostly activation of IgA-producing cells and secretion of IgA to the lung lavage. In contrast, the majority (80-90%) of Ab detected in the serum belong to the IgG2a subclass and their serum level is maintained at a high level during the whole period of the response. The relative level of virus-specific serum IgG2a in correlation with the production of IgG2a Ab found predominantly in MLN and lung is highly dependent on the viral dose used for priming or challenge. As IgG2a ASC can be detected at relatively low numbers in the spleen and BM these results suggest that the production of the dominant IgG2a isotype of serum Ab occurs close to the viral challenge site. These data, however, point to distinct isotypic regulation in systemic versus local virus-specific Ab responses.

Abstract
To investigate the antibody response after local application of lung-pathogenic bacteria, pigs were immunized with viable or inactivated Actinobacillus pleuropneumoniae by the oral and aerogenous route. After 3 weeks class-specific immunoglobulins against purified A. pleuropneumoniae capsular polysaccharides (CP) were determined in serum and BALF by ELISA. A significant increase of IgA antibodies was found in BALF but not in sera of all immunized pigs. Oral immunization with viable A. pleuropneumoniae and aerosol immunization with either viable or inactivated bacteria resulted in a significant increase of IgG antibodies to the CP antigen in BALF, whereas only aerosol exposure to viable bacteria resulted in a significant increase in IgG antibodies in serum. A significant increase in anti-CP IgM in BALF was observed after aerosol exposure but not after oral immunization. IgM antibodies towards CP increased significantly by both routes of immunization with viable bacteria. The anti-CP activity of all three isotypes in sera and BALF was low in all groups compared with the positive controls, although inoculation of viable A. pleuropneumoniae led to higher levels of antibody concentration than inactivated bacteria. Our results indicate a traffic of primed lymphocytes from the gut into the bronchoalveolar airways and further support the hypothesis that polysaccharide-specific B cells may functionally mature at the mucosal surfaces.

Abstract
After localized lung immunization and challenge, antigen-specific antibody continues to be produced in the immunized lung lobes of dogs for years after the last antigen exposure. Lavage fluid from immunized lung lobes contains significantly more antigen-specific antibody than lavage fluid from control lung lobes, and only cells from lung lobes exposed to antigen produce antibody. Although cells lavaged from the lung produce antibody, it is possible that cells in the lung interstitium or lymphoid tissues may be more important in long-term antibody production after lung immunization and challenge. The goal of this study was to compare the levels of antibody production by cells from dogs 2 yr after pulmonary immunization and challenge. Cells were evaluated from lung lavage, lung tissue, tracheobronchial lymph nodes, and distant lymphoid tissues. The results showed that cells lavaged from lung lobes immunized and challenged with sheep red blood cells (SRBC) were producing anti-SRBC IgG antibody 2 yr after the last antigen challenge. However, cells obtained by mincing tissues from immunized lung lobes were producing significantly higher levels of antibody than lavage cells. In contrast, lavage or tissue cells obtained from the control lobes did not produce detectable antibody. Only a low level of anti-SRBC IgG was produced by cells from the tracheobronchial lymph nodes, and minimal antibody was produced by cells from blood, spleen, or mesenteric and popliteal lymph nodes.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Nosocomial pneumonia is frequent after haemorrhage and trauma, and often contributes to multiple organ system failure, morbidity and mortality in this setting. Although the percentages and numbers of bacterial polysaccharide antigen-specific pulmonary B cell clonal precursors are markedly decreased after haemorrhage, the effects of haemorrhage on pulmonary plasma cells actually producing antibody to these antigens are unknown. To investigate this question, the numbers of intraparenchymal pulmonary plasma cells producing antibody against the bacterial polysaccharide antigen levan (from Aerobacter levanicum) as well as bacterial antigen specific secretory IgA (sIgA) titres in the lungs were determined at various time points after 30% blood volume haemorrhage. Reduced numbers of bacterial antigen specific pulmonary plasma cells were found for more than 21 days following haemorrhage. An almost complete disappearance from the lungs of levan specific plasma cells occurred between 3 and 21 days after blood loss. Titres of bacterial antigen specific sIgA in the lungs were decreased starting at 3 days post-haemorrhage and remained significantly depressed for more than 35 days after blood loss. These results demonstrate that haemorrhage produces profound and long-lasting suppression in bacterial antigen-specific pulmonary plasma cell function. Because these effects do not occur immediately post-haemorrhage, immunization techniques able to enhance bacterial antigen specific sIgA titres at pulmonary surfaces may be able to increase resistance to nosocomial pneumonia if administered shortly after injury and blood loss.

Abstract
Enhancement of bacterial antigen-specific secretory IgA (sIgA) titres in the lungs may enhance resistance to infections, such as pneumonia, occurring at this mucosal surface. To examine this issue, we intranasally administered liposomes containing bacterial polysaccharide antigens from Aerobacter levanicum, Pseudomonas aeruginosa and Streptococcus pneumoniae. In each case, increased titres of bacterial polysaccharide-specific sIgA could be achieved in the lungs following intranasal immunization with antigen encapsulated in liposomes. In comparison with oral immunization, which required high doses of polysaccharide antigen even when coadministered with adjuvant, intranasal administration of liposomes containing polysaccharide antigens achieved a similar pulmonary sIgA response with approximately 1/30 the amount of antigen necessary with oral immunization. In the case of P. aeruginosa, the magnitude of the sIgA response following intranasal immunization was sufficient to significantly reduce mortality from pneumonia produced by this organism. These results demonstrate that liposome-based mucosal immunization strategies can induce increased bacterial polysaccharide antigen-specific sIgA titres in the lung, and reduce susceptibility to pneumonia.

Abstract
Nosocomial pneumonia, often due to Pseudomonas aeruginosa, occurs frequently after haemorrhage and trauma, and contributes to the increased incidence of morbidity and mortality in this clinical setting. In order to determine if enhancement of bacterial antigen-specific secretory IgA (sIgA) titres in the lungs can increase resistance to P. aeruginosa pneumonia following haemorrhage, we investigated oral immunization strategies, using bacterial polysaccharides (levan, from Aerobacter levanicum, and P. aeruginosa polysaccharide type I) and adjuvant (cholera toxin and the B-subunit of cholera toxin), capable of increasing bacterial polysaccharide-specific pulmonary secretory antibody titres. Oral co-administration of 1000 micrograms levan and 10 micrograms cholera toxin resulted in increased titres of levan-specific sIgA in lung lavages and increased numbers of levan-specific pulmonary plasma cells, but no changes in serum anti-levan titres. Similarly, oral co-administration of 1000 micrograms P. aeruginosa polysaccharide and 10 micrograms cholera toxin produced increased anti-P. aeruginosa polysaccharide titres in lung lavages. Significant decreases in anti-levan pulmonary sIgA titres and in numbers of levan-specific pulmonary plasma cells were found when oral immunization with levan and cholera toxin was performed 4 days following haemorrhage, but not if the mice were immunized 8 h after blood loss. Although haemorrhage markedly increased the susceptibility of mice to P. aeruginosa pneumonia, significant protection from mortality could be achieved through oral immunization with 1000 micrograms P. aeruginosa polysaccharide and 10 micrograms cholera toxin 8 h after haemorrhage. These results demonstrate that haemorrhage induces marked alterations in bacterial antigen-specific pulmonary B-cell responses, which contribute to the increased susceptibility to infection in this setting.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Primary immunization with a single inoculum of either micelles or iscoms containing influenza A virus glycoproteins failed to induce either B or cytotoxic T (Tc) cell responses. In contrast, immunization with two inocula of iscoms, but not micelles, resulted in the appearance of influenza virus-specific antibody-secreting cells (ASC) but not Tc cells in the lung. There was a 10-fold increase in Tc cell precursor frequency and an increase in ASC generated by secondary in vitro stimulation of lung cell cultures obtained from mice primed with iscoms but not micelles. In mice primed with infectious virus, secondary immunization with either micelles or iscoms increased the number of ASC in the lung and elicited virus-specific Tc cell responses. In contrast homologous virus challenge failed to induce detectable secondary B or Tc cell responses.

Abstract
Vaccines have been used almost exclusively to prevent or control infectious diseases with the aim of long-lasting immunity. Some, composed of attenuated viruses, have been highly successful and this may be due to the generation of high levels of B memory cells and their steady recruitment to form antibody secreting cells. Some diseases, notably AIDS, are a much greater challenge and it will need all the expertise of molecular biologists and immunologists to devise a vaccine which may control the disease. Vaccination to enhance or decrease the action of hormones is now being actively explored as a practical way of controlling fertility in mammals or enhancing selected properties of other hormones. In this situation, the desired effect is for a defined period, possibly one year or less. These requirements underline further the need for controlled release formulations for vaccine delivery.
