The Transcription Factor T-bet Resolves Memory B Cell Subsets with Distinct Tissue Distributions and Antibody Specificities in Mice and Humans. Immunity 2020; 52:842-855.e6. [PMID: 32353250 DOI: 10.1016/j.immuni.2020.03.020] [Citation(s) in RCA: 130] [Impact Index Per Article: 32.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2018] [Revised: 01/28/2020] [Accepted: 03/27/2020] [Indexed: 12/11/2022]
Abstract
B cell subsets expressing the transcription factor T-bet are associated with humoral immune responses and autoimmunity. Here, we examined the anatomic distribution, clonal relationships, and functional properties of T-bet+ and T-bet- memory B cells (MBCs) in the context of the influenza-specific immune response. In mice, both T-bet- and T-bet+ hemagglutinin (HA)-specific B cells arose in germinal centers, acquired memory B cell markers, and persisted indefinitely. Lineage tracing and IgH repertoire analyses revealed minimal interconversion between T-bet- and T-bet+ MBCs, and parabionts showed differential tissue residency and recirculation properties. T-bet+ MBCs could be subdivided into recirculating T-betlo MBCs and spleen-resident T-bethi MBCs. Human MBCs displayed similar features. Conditional gene deletion studies revealed that T-bet expression in B cells was required for nearly all HA stalk-specific IgG2c antibodies and for durable neutralizing titers to influenza. Thus, T-bet expression distinguishes MBC subsets that have profoundly different homing, residency, and functional properties, and mediate distinct aspects of humoral immune memory.

Abstract
Vaccine development involves time-consuming and expensive evaluation of candidate vaccines in animal models. As mediators of both innate and adaptive immune responses dendritic cells (DCs) are considered to be highly important for vaccine performance. Here we evaluated how far the response of DCs to a vaccine in vitro is in line with the immune response the vaccine evokes in vivo. To this end, we investigated the response of murine bone marrow-derived DCs to whole inactivated virus (WIV) and subunit (SU) influenza vaccine preparations. These vaccine preparations were chosen because they differ in the immune response they evoke in mice with WIV being superior to SU vaccine through induction of higher virus-neutralizing antibody titers and a more favorable Th1-skewed response phenotype. Stimulation of DCs with WIV, but not SU vaccine, resulted in a cytokine response that was comparable to that of DCs stimulated with live virus. Similarly, the gene expression profiles of DCs treated with WIV or live virus were similar and differed from that of SU vaccine-treated DCs. More specifically, exposure of DCs to WIV resulted in differential expression of genes in known antiviral pathways, whereas SU vaccine did not. The stronger antiviral and more Th1-related response of DCs to WIV as compared to SU vaccine correlates well with the superior immune response found in mice. These results indicate that in vitro stimulation of DCs with novel vaccine candidates combined with the assessment of multiple parameters, including gene signatures, may be a valuable tool for the selection of vaccine candidates.

Abstract
Protection from influenza A virus (IAV) challenge requires switched, high affinity Abs derived from long-lived memory B cells and plasma cells. These B cell subsets are generated in germinal centers (GCs), hallmark structures of T helper cell-driven B cell immunity. A full understanding of the GC reaction after respiratory IAV infection is lacking, as is the characterization of T follicular helper (TFH) cells that support GCs. Here, GC B cell and TFH cell responses were studied in mice following pulmonary challenge with IAV. Marked GC reactions were induced in draining lymph nodes (dLNs), lung, spleen and nasal-associated lymphoid tissue (NALT), although the magnitude and kinetics of the response was site-specific. Examination of switching within GCs demonstrated IgG2+ cells to compose the largest fraction in dLNs, lung and spleen. IgA+ GC B cells were infrequent in these sites, but composed a significant subset of the switched GC population in NALT. Further experiments demonstrated splenectomized mice to withstand a lethal recall challenge, suggesting the spleen to be unnecessary for long-term protection in spite of strong GC responses in this organ. Final studies showed that TFH cell numbers were highest in dLNs and spleen, and peaked in all sites prior to the height of the GC reaction. TFH cells purified from dLNs generated IL-21 and IFNγ upon activation, although CD4+CXCR5− T effector cells produced higher levels of all cytokines. Collectively, these findings reveal respiratory IAV infection to induce strong T helper cell-driven B cell responses in various organs, with each site displaying unique attributes.

Abstract
The role and kinetics of respiratory immunoglobulins in AIV infection has not been investigated. In this study we determined the numbers of both total antibody secreting cells (ASC) and virus-specific ASC in lung, spleen, blood and bone marrow (BM) following low-pathogenic AIV infection. Antiviral humoral immune responses were induced both locally in the lung and systemically in the spleen. Responses in the lung and BM preceded responses in the spleen and in blood, with virus-specific IgY ASC already detected in lung and BM from 1 week post-primary inoculation, indicating that respiratory immune responses are not induced in the spleen, but locally in the lung. ASC present in the blood of the lungs and co-isolated during lymphocyte isolation from the lungs have no major impact on the ASC detected in the lungs based on statistical correlation.

Abstract
In this study, we evaluated the immunogenicity and protective efficacy of a candidate attenuated H5N1 pre-pandemic influenza vaccine of clade 2.3.4, rgAnhui, which was reverse genetically generated from highly virulent A/Anhui/01/2005 (H5N1) wild-type virus. When a low-dose antigen (0.3μg HA) vaccine was combined with aluminum hydroxide adjuvant, virus neutralization and anti-HA IgG antibodies induced in the sera of vaccinated mice showed similar levels as those in mice vaccinated with non-adjuvanted high-dose antigen (3μg HA) vaccine. Serum antibodies had broad reactivity against highly pathogenic H5N1 viruses of both homologous and heterologous clades. All mice vaccinated with adjuvanted and non-adjuvanted rgAnhui vaccines at low and high antigen doses survived, without any significant weight loss, lethal challenge infection with homologous clade 2.3.4 viruses, including antigenic variant virus and heterologous clade 2.1.3. Mice vaccinated with low-dose antigen without adjuvant, however, exhibited 20% and 60% survival rates against clade 1 and clade 2.2 viruses, respectively; but, addition of adjuvant improved these rates to 80% and 100%, respectively. The data strongly suggest that aluminum hydroxide-adjuvanted rgAnhui vaccine can elicit broad cross-reactive and protective immunities against homologous and heterologous clades, and that the rgAnhui vaccine is a useful pre-pandemic H5N1 vaccine.

Abstract
Swine-origin H1N1 influenza virus (S-OIV) appeared in 2009 with a higher incidence rate among children. Although fever was the most common symptom, some complicated cases occurred. We evaluated the percentages of effector T cells, B cells, and regulatory T cells in peripheral blood from 5 children infected by S-OIV (1 with acute necrotizing encephalitis, 2 with pneumonia, and 2 without complications), 5 children with seasonal influenza, and 5 healthy children. We found higher percentages of T-bet(+) CD4(+)CD8(+) T cells, monocytes, and B cells, granzyme B(+) and perforin(+) CD4(+), and CD8(+) T cells in affected children with both seasonal and H1N1 influenza than in controls, whereas both groups demonstrated similar percentages of CD4(+)CD25(+)Foxp3(+) regulatory T cells. In infected children with complications we observed high percentages of perforin(+) and interferon-γ(+) CD4(+) and CD8(+) T cells associated with low percentages of T regulatory cells. Our data suggest a dysregulation of antipathogen type I immune responses in complicated S-OIV infections.

Abstract
We generated influenza virus-like particles (VLPs) containing the wild type (WT) H5 hemagglutinin (HA) from A/Viet Nam/1203/04 virus or a mutant H5 HA with a deletion of the multibasic cleavage motif. VLPs containing mutant H5 HA were found to be as immunogenic as VLPs containing WT HA. A single intramuscular vaccination with either type of H5 VLPs provided complete protection against lethal challenge. In contrast, the recombinant H5 HA vaccine was less immunogenic and vaccination even with a 5 fold higher dose did not induce protective immunity. VLP vaccines were superior to the recombinant HA in inducing T helper type 1 immune responses, hemagglutination inhibition titers, and antibody secreting cells, which significantly contribute to inducing protective immunity after a single dose vaccination. This study provides insights into the potential mechanisms of improved immunogenicity by H5 VLP vaccines as an approach to improve the protective efficacy against potential pandemic viruses.

Abstract
Intramuscular administration of inactivated influenza virus vaccine is the main vaccine platform used for the prevention of seasonal influenza virus infection. In clinical trials, inactivated H5N1 vaccines have been shown to be safe and capable of eliciting immune correlates of protection. However, the H5N1 vaccines are poorly immunogenic compared to seasonal influenza virus vaccines. Needle-free vaccination would be more efficient and economical in a pandemic, and the development of an effective and safe mucosal adjuvant will be an important milestone. A stabilized chemical analog of double-stranded RNA, PIKA, was previously reported to be a potent mucosal adjuvant in a murine model. While PIKA stimulates dendritic cells in vitro, little was known about its receptor and adjuvanting mechanism in vivo. In this study, we demonstrated that the immunostimulatory effect of PIKA resulted in an increased number of mature antigen-presenting cells, with the induction of proinflammatory cytokines at the inoculation site. In addition, coadministration of PIKA with a poorly immunogenic H5N1 subunit vaccine led to antigen sparing and quantitative and qualitative improvements of the immune responses over those achieved with an unadjuvanted vaccine in mice. The adjuvanted vaccine provided protection against lethal challenge with homologous and heterologous H5N1 wild-type viruses. Mice lacking functional TLR3 showed diminished cytokine production with PIKA stimulation, diminished antibody responses, and reduced protective efficacy against wild-type virus challenge following vaccination. These data suggest that TLR3 is important for the optimal performance of PIKA as an adjuvant. With its good safety profile and antigen-sparing effect, PIKA could be an attractive adjuvant for use in future pandemics.

Abstract
Background Simple and effective vaccine administration is particularly important for annually recommended influenza vaccination. We hypothesized that vaccine delivery to the skin using a patch containing vaccine-coated microneedles could be an attractive approach to improve influenza vaccination compliance and efficacy. Methodology/Principal Findings Solid microneedle arrays coated with inactivated influenza vaccine were prepared for simple vaccine delivery to the skin. However, the stability of the influenza vaccine, as measured by hemagglutination activity, was found to be significantly damaged during microneedle coating. The addition of trehalose to the microneedle coating formulation retained hemagglutination activity, indicating stabilization of the coated influenza vaccine. For both intramuscular and microneedle skin immunization, delivery of un-stabilized vaccine yielded weaker protective immune responses including viral neutralizing antibodies, protective efficacies, and recall immune responses to influenza virus. Immunization using un-stabilized vaccine also shifted the pattern of antibody isotypes compared to the stabilized vaccine. Importantly, a single microneedle-based vaccination using stabilized influenza vaccine was found to be superior to intramuscular immunization in controlling virus replication as well as in inducing rapid recall immune responses post challenge. Conclusions/Significance The functional integrity of hemagglutinin is associated with inducing improved protective immunity against influenza. Simple microneedle influenza vaccination in the skin produced superior protection compared to conventional intramuscular immunization. This approach is likely to be applicable to other vaccines too.

Abstract
Background and Objective In this study we investigated the levels of cytokines and chemokines produced locally and systemically after influenza vaccination of patients undergoing tonsillectomy. Methods Blood and saliva were collected prior to, and 1 or 2 weeks after vaccination at the time of the tonsillectomy. The cytokine and chemokine concentrations were determined in both unstimulated (whole blood, serum and saliva) and in vitro influenza stimulated peripheral blood mononuclear cell (PBMC) and tonsillar lymphocyte (TMC) cultures. Results We found that influenza vaccination elicited protective levels of serum haemagglutination inhibition antibodies and a significant local antibody response in the saliva. No significant differences were observed in the cytokine or chemokine levels 1 or 2 weeks post‐vaccination in either the serum or saliva. Similarly, no significant differences were found in the gene expression levels in PBMC after vaccination, but interleukin (IL)‐2, IL‐4, γ‐interferon and transforming growth factor‐β were slightly elevated at 1 week post‐vaccination but decreased by 2 weeks post‐vaccination. In contrast, increased concentrations of a mixture of type 1, type 2 and inflammatory cytokines were produced 1 and 2 weeks after influenza vaccination by in vitro‐stimulated PBMC and TMC. Conclusion We show that cytokine responses can be measured after influenza vaccination in in vitro‐stimulated lymphocytes but not directly in the blood or saliva. These results will provide a useful baseline that can be used for comparison of the immune response in human volunteers involved in clinical trials of novel influenza vaccines.

Abstract
Background For protection against (re‐)infection by influenza virus not only the magnitude of the immune response but also its quality in terms of antibody subclass and T helper profile is important. Information about the type of immune response elicited by vaccination is therefore urgently needed. Objectives The aim of the study was to evaluate in detail the immune response elicited by three current influenza vaccine formulations and to shed light on vaccine characteristics which determine this response. Methods Mice were immunized with whole inactivated virus (WIV), virosomes (VS) or subunit vaccine (SU). Following subsequent infection with live virus, serum antibody titers and Th cell responses were measured. The effects of the vaccines on cytokine production by conventional and plasmacytoid dendritic cells were investigated in vitro. Results and conclusions In Balb/c mice (Th2 prone) as well as in C57Bl/6 mice (Th1 prone), WIV induced consistently higher hemagglutination‐inhibition titers and virus‐neutralizing antibody titers than VS or SU. In contrast to VS and SU, WIV stimulated the production of the antibody subclasses IgG2a (Balb/c) and IgG2c (C57BL/6), considered to be particularly important for viral clearance, and activation of IFN‐γ‐producing T cells. Similar to live virus, WIV stimulated the production of proinflammatory cytokines by conventional dendritic cells and IFN‐α by plasmacytoid cells, while VS and SU had little effect on cytokine synthesis by either cell type. We conclude that vaccination with WIV in contrast to VS or SU results in the desired Th1 response presumably by induction of type I interferon and other proinflammatory cytokines.

Abstract
The spleen, bone marrow and lymph nodes are all known to be important organs for the initiation and maintenance of an immune response after vaccination. To investigate the differences and similarities in the humoral and cellular immune responses between these tissues, we vaccinated mice once or twice with the conventional human dose (15 microg HA) of influenza A (H3N2) split virus vaccine and analysed the sera and lymphocytes collected from the different sites. We found that the response of antibody secreting cells (ASC) in the lymph nodes appeared to be more transient than in the spleen, possibly because the influenza-specific IgM ASC in particular might have migrated from the lymph nodes immediately after activation. The serum antibody response was found to initially correspond with the ASC response elicited in the spleen and the lymph nodes, whereas the later serum IgG reflected the ASC response in the bone marrow. Proliferation of influenza-specific CD4(+) and CD8(+) cells was predominantly observed in the spleen and was associated with higher concentrations of cytokines than in the lymph nodes. The finding of influenza-specific CD8(+) cell proliferation in the spleen indicates that a split influenza virus vaccine may stimulate a cytotoxic T-cell response. Our results also showed that the primary response elicited a mixed Th1/Th2 profile, whereas the secondary response was skewed towards a Th2 type. Each of the three tissues had a different immunological pattern, suggesting that in preclinical vaccine studies, there is a case for investigating a range of immunological sites.

Abstract
Vaccination provides the most effective method of limiting the impact of influenza. Inactivated influenza vaccines are available in three formulations and more information needs to be generated on how antigen presented in different vaccine formulations influences the subsequent immune response. In the present study, we have investigated the effect of two different influenza vaccine formulations on the resulting antibody and cytokine responses and compared these responses with influenza infection. Mice were vaccinated intramuscularly with one or two doses of whole or split virus vaccine or alternatively intranasally infected with influenza virus. Lymphocytes were isolated from spleen cells and stimulated in vitro for 24 or 72 h for analysis of cytokine profile at the gene expression and at the protein level. Additionally, whole blood was collected and the serum antibody response investigated by haemagglutination inhibition (HI) and enzyme-linked immunosorbent assay (ELISA). We found that one dose of whole virus vaccine induced higher antibody and cytokine responses and thus was more immunogenic in unprimed mice than split virus vaccine. Whole virus vaccine induced a strong IFN-gamma (type 1) immune response after one dose of vaccine and a more mixed cytokine response after the second dose. Split virus vaccine induced a type 2 response, particularly after two vaccine doses. Our results show that two doses of vaccine (both vaccine formulation) were more effective in induction of Th2 type of cytokines and thus indicate that both the formulation and also the number of vaccine doses substantially influences the magnitude and quality of the immune response.

Abstract
We have previously found that whole influenza virus vaccine induced a more rapid and stronger humoral response, particularly after the first dose of vaccine, than split virus vaccine in mice. In this study, we have evaluated the protective efficacy of whole and split influenza virus vaccines in mice using a nonlethal upper respiratory tract challenge model. We have also investigated the immunological correlates associated with no or very little viral shedding after viral challenge. Vaccination resulted in reduced viral shedding and shortened the duration of infection by at least 2 days. After one dose of vaccine, whole virus vaccine generally resulted in less viral shedding than split virus vaccine. In contrast, two doses of split virus vaccine, particularly the highest vaccine strengths of 15 and 30 microg HA, most effectively limited viral replication and these mice had high concentrations of prechallenge influenza-specific serum IgG. The vaccine formulation influenced the IgG2a/IgG1 ratio, and this IgG subclass profile was maintained upon challenge to some extent, although it did not influence the level of viral shedding. The concentration of postvaccination serum IgG showed an inverse relationship with the level of viral shedding after viral challenge. Therefore, serum IgG is an important factor in limiting viral replication in the upper respiratory tract upon challenge of an antigenically similar virus.

Abstract
The aim of this study was to compare the kinetics and the magnitude of the humoral immune response to two different influenza vaccine formulations, whole and split virus vaccines. BALB/c mice were immunized intramuscularly with one or two doses (3 weeks apart) of 7.5, 15 or 30 microg of haemagglutinin of monovalent A/Panama/2007/99 (H3N2) split or whole virus vaccine. The two vaccine formulations induced similar kinetics of the antibody-secreting cells response; however, differences in the magnitude were observed in the spleen and bone marrow. Vaccination with whole virus vaccine generally elicited a quicker and higher neutralizing antibody response, particularly after the first dose of vaccine. The two vaccine formulations gave different immunoglobulin G (IgG) subclass profiles. Split virus vaccine stimulated both IgG1 and IgG2a antibodies suggestive of mixed T-helper 1 (Th1) and Th2 response, whereas whole virus vaccine induced mainly an IgG2a antibody response, which is indicative of a dominant Th1 response. The increased immunogenicity of whole virus vaccine in a naïve population could reduce the vaccine concentration needed to provide protective immunity.

Abstract
Previous studies have indicated that B cells make a significant contribution to the resolution of influenza virus infection. To determine how B cells participate in the control of the infection, we transferred intact, major histocompatibility complex class II (MHC-II)-negative or B-cell receptor (BCR)-transgenic spleen cells into B-cell-deficient and CD8(+) T-cell-depleted muMT mice, termed muMT(-8), and tested them for ability to recover from infection. muMT(-8) mice that received no spleen cells invariably succumbed to the infection within 20 days, indicating that CD4(+) T-cell activities had no significant therapeutic activity on their own; in fact, they were harmful and decreased survival time. Interestingly, however, they became beneficial in the presence of antiviral antibody (Ab). Injection of MHC-II((-/-)) spleen cells, which can provide CD4(+) T-cell-independent (TI) but not T-cell-dependent (TD) activities, delayed mortality but only rarely resulted in clearance of the infection. By contrast, 80% of muMT(-8) mice injected with normal spleen cells survived and resolved the infection. Transfer of BCR-transgenic spleen cells, which contained approximately 10 times fewer virus-specific precursor B cells than normal spleen cells, had no significant impact on the course of the infection. Taken together, the results suggest that B cells contribute to the control of the infection mainly through production of virus-specific Abs and that the TD Ab response is therapeutically more effective than the TI response. In addition, CD4(+) T cells appear to contribute, apart from promoting the TD Ab response, by improving the therapeutic activity of Ab-mediated effector mechanisms.

Abstract
New approaches to visualizing antigen-specific primary responses to influenza and the development of memory subsets in distinct sites suggest that both CD4 and CD8 T cells play complex roles in primary viral clearance and have the potential to contribute to protection from secondary infection.

Abstract
Antigenic drift of swine influenza A (H3N2) viruses away from the human A/Port Chalmers/1/73 (H3N2) strain, used in current commercial swine influenza vaccines, has been demonstrated in The Netherlands and Belgium. Therefore, replacement of this human strain by a more recent swine H3N2 isolate has to be considered. In this study, the efficacy of a current commercial swine influenza vaccine to protect pigs against a recent Dutch field strain (A/Sw/Oedenrode/96) was assessed. To evaluate the level of protection induced by the vaccine it was compared with the optimal protection induced by a previous homologous infection. Development of fever, virus excretion, and viral transmission to unchallenged group mates were determined to evaluate protection. The vaccine appeared efficacious in the experiment because it was able to prevent fever and virus transmission to the unchallenged group mates. Nevertheless, the protection conferred by the vaccine was sub-optimal because vaccinated pigs excreted influenza virus for a short period of time after challenge, whereas naturally immune pigs appeared completely protected. The immune response was monitored, to investigate why the vaccine conferred a sub-optimal protection. The haemagglutination inhibiting and virus neutralising antibody responses in sera, the nucleoprotein-specific IgM, IgG, and IgA antibody responses in sera and nasal secretions and the influenza-specific lymphoproliferation responses in the blood were studied. Vaccinated pigs developed the same or higher serum haemagglutination inhibiting, virus neutralising, and nucleoprotein-specific IgG antibody titres as infected pigs but lower nasal IgA titres and lymphoproliferation responses. The lower mucosal and cell-mediated immune responses may explain why protection after vaccination was sub-optimal.

Abstract
The ability of non-ionic surfactant vesicles to induce systemic immune responses in mice following oral immunisation was studied using a standard antigen (bovine serum albumin), a synthetic measles peptide and an influenza sub-unit vaccine. The effectiveness of this formulation was significantly increased by incorporating bile salts (in particular deoxycholate) into the formulation. We have named the resulting vesicles bilosomes. We found that the most effective immunisation protocol was to give two doses of vaccine three days apart and then repeat this protocol two weeks later. Following this method, preparation of measles peptide in bilosomes produced a specific cell mediated response, as measured by splenocyte proliferation and IL-2 production. Of particular significance, these studies demonstrate that oral administration of bilosomes incorporating the influenza sub-unit vaccine could induce as potent an antibody response as the parenterally administered vaccine containing the same quantity of antigen. In addition, the Th1/Th2 balance, as measured by antibody subclasses, was similar whether animals were immunised by the oral or the parenteral vaccine route. As bilosomes are prepared from naturally occurring lipids and have no apparent toxicity associated with their use, they represent a useful modification of conventional lipid vesicle based systems for the oral delivery of proteins and peptides.

Abstract
The immunoglobulin isotype-specific responses in serum and at the respiratory mucosa of pigs after a primary infection with influenza virus were studied. To do this, we developed an aerosol challenge model for influenza in specified pathogen-free (SPF) pigs and isotype-specific enzyme-linked immunosorbent assays (ELISAs). Ten-week-old pigs were inoculated without anesthesia in the nostrils with an aerosol of the field isolate influenza A/swine/Neth/St. Oedenrode/96 (H3N2). The infection caused acute respiratory disease that closely resembled the disease observed in some outbreaks of influenza among finishing pigs, which were not complicated by bacterial infections. Pigs showed clinical signs characterized by fever, dyspnea, and anorexia. At necropsy on postinfection days 1 and 2, an exudative endobronchitis was observed throughout the lung. Viral antigen was present in the epithelial cells of the bronchi and bronchioli and virus was isolated from bronchioalveolar and nasal lavage fluids and from pharyngeal swabs until 5 days after infection. With the isotype-specific ELISAs, viral nucleoprotein specific immunoglobulin (Ig) M, IgG1, and IgA antibody responses were measured in serum and bronchioalveolar and nasal lavage fluids. To determine whether the antibodies were produced and secreted at the respiratory mucosa or were serum-derived, the specific activity (ie, the ratio of antibody titer to Ig concentration) was calculated for each isotype. The IgA and interestingly also a substantial part of the IgG1 antibody response in pigs upon infection with influenza virus was shown to be a mucosal response. Local production of specific IgA in the nasal mucosa, and of specific IgA and IgG1 in the lung was demonstrated. These results indicate that protective efficacy of vaccination can be improved by an immunization procedure that preferentially stimulates a mucosal immune response. The aerosol challenge model in SPF pigs and the isotype-specific ELISAs that we developed can be useful for evaluating various strategies to improve efficacy of porcine influenza vaccines and to study the immune mechanisms underlying the observed protection.

Abstract
BACKGROUND Treatment of malignant disease in children is often associated with low serum immunoglobulin and reduced specific antibody levels. The aim of this study was to investigate if the functional affinity of specific antibodies in serum and saliva is reduced as well and to evaluate if antigenic exposure or treatment duration affects this antibody avidity. PROCEDURE Serum samples were obtained from 45 children and salivary specimens from 30 children with malignant disease. The children were tested either prior to, during, or after chemotherapy. Levels of antibody to E. coli O and to poliovirus type 1 antigens were determined using an ELISA and isotype-specific relative antibody avidity was measured using thiocyanate to elute antibodies from solid-phase immobilized antigens. RESULTS Children with malignant disease had higher levels and relative avidity indexes of serum antibodies to both antigens as compared to controls. The duration of treatment and type of malignant disease were unrelated to these parameters. In saliva, the level of antibodies to E. coli O antigens, but not to poliovirus type 1 antigen, increased during treatment. CONCLUSIONS Both the amount and avidity of serum antibodies to these antigens are increased in children with malignant disease. This may be due to a dysregulation of the immune system caused by the malignancy and seems not to be dependent on exposure. In contrast, the avidity and levels of these antibodies in saliva seem to correlate with the presence of antigenic exposure.

Abstract
Multipeptide constructs, comprising adjacent sequences of the 317-341 intersubunit region of immature influenza A hemagglutinin (H1N1), were designed and the functional properties of these branched peptides were compared to that of the corresponding linear peptides. In vivo studies revealed that the immunogenicity of the peptides was dependent on the presence of the hydrophobic fusion peptide (comprised in FP3), encompassing the N-terminal 1-13 sequence of the HA2 subunit. Antibody and T cell recognition, however, was directed against the 317-329 HA1 sequence, comprised in the P4 peptide. Multiple copies of P4, covalently linked by branched lysine residues, significantly enhanced the efficiency of antibody binding and the capacity of peptides to elicit B- and T-cell responses. A fraction of peptide induced antibodies reacted with immature or with proteolitically cleaved hemagglutinin (HA) molecules pretreated at low pH. Immunization with a multipeptide construct, (P4)4-FP3, not only resulted in elevated antibody and T cell responses but conferred enhanced protection against lethal A/PR/8/34 (H1N1) infection as compared to its subunit peptides. The beneficial functional properties of this artificial peptide antigen may be acquired by multiple properties including: (i) stabilized peptide conformation which promotes strong, polyvalent binding to both antibodies and MHC class II molecules; (ii) appropriate P4 conformation for antibody recognition stabilized by the covalently coupled fusion peptide, resulting in the production of virus cross reactive antibodies which inhibit the fusion activity of the virus; (iii) activation of peptide specific B cells which potentiate antigen presentation and peptide specific T cell responses; and (iv) generation of helper T cells which secrete lymphokines active in the resolution of infection.

Abstract
Mice expressing the hemagglutinin (HA) gene of influenza virus PR8 (H1 subtype) under the control of kappa light chain promoter and enhancer have been generated. They express HA in and on B cells, and are tolerant to HA. In vitro, only lipopolysaccharide (LPS) blasts but not resting B cells of transgenic mice can stimulate HA-specific helper T cells of HA-specific alpha/beta T cell receptor (TCR)-transgenic mice. Transfer of HA-transgenic LPS blasts into syngeneic, non-transgenic recipients primes HA-specific antibody responses. Resting, small HA-transgenic B cells, which were purified by fluorescence-activated cell sorting, prime lower antibody responses. Host B cells produce the HA-specific antibody response. The donor HA-transgenic B cells need to express major histocompatibility complex (MHC) class II molecules and need to be alive to induce the antibody response in the host. Most notably, the host antibody response never produces detectable levels of IgM, but only of switched IgG isotypes. Neither resting nor activated HA-transgenic B cells induce tolerance in antibody responses. These results suggest that HA-transgenic B cells, presenting both the intact antigen on the cell surface and peptides of the antigen on MHC class II, are effective inducers of helper T cell responses, and as judged by the Ig-isotype response pattern, which is mainly IgG1, of Th2 type.

Abstract
We have generated new influenza A virus live attenuated vaccine candidates by site-directed mutagenesis and reverse genetics. By mutating specific amino acids in the PB2 polymerase subunit, two temperature-sensitive (ts) attenuated viruses were obtained. Both candidates have 38 degrees C shutoff temperatures in MDCK cells, are attenuated in the respiratory tracts of mice and ferrets, and have very low reactogenicity in ferrets. Infection of mice or ferrets with either mutant conferred significant protection from challenge with the homologous wild-type virus. Three tests for genetic stability were used to assess the propensity for reversion to virulence: 14 days of replication in nude mice, growth at 37 degrees C in tissue culture, and serial passage in ferrets. One candidate, which contains mutations intended to reduce the ability of PB2 to bind to cap structures, was stable in all three assays, whereas the second candidate, which contains mutations found only in other ts strains of influenza virus, lost its ts phenotype in the last two assays. This approach has therefore enabled the creation of live attenuated influenza A virus vaccine candidates suitable for human testing.

Covalent conjugates of hen egg lysozyme (HEL) and anti-major histocompatibility complex (MHC) class II monoclonal antibodies (mAb) were used to immunize mice intranasally. Three weeks after intranasal (IN) priming, mice responded rapidly to IN challenge with a mixture of HEL and cholera toxin (CT), by producing large titres of anti-HEL IgA and IgG1 antibody in serum, and IgA antibody in nasal secretions. No secondary response to HEL plus CT occurred in mice that received no priming or mice primed with HEL alone. The secondary serum IgG antibody response was dominated by the IgG1 subclass. HEL combined with CT adjuvant worked much better than HEL alone in producing the secondary response. Control conjugates, containing an IgG isotype-matched mAb without specificity for mouse tissues, provided poor priming. Mice expressing MHC class II molecules, to which the anti-MHC II mAb could not bind, produced a weak antibody response compared with those that expressed the appropriate. MHC class II molecule. Our results demonstrate that immunotargeting to MHC class II molecules via the IN route allows priming of the local IgA and circulating IgG antibody, and indicate that this technique is a feasible approach for delivery of subunit vaccines in the upper respiratory tract.

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.
