Abstract
Whole cell pertussis (wP) vaccines are gradually being replaced by aluminum salt-adjuvanted acellular pertussis (aP) vaccines. These promote CD4(+) T cell responses with a non-protective Th2 component, while protective immune mechanisms to B. pertussis may rather involve long-lived Th1/Th17 type CD4(+) T cells. Here we asked whether addition of a non-toxic meningococcal LPS derivative, LpxL1, as adjuvant can favorably modulate the aP-induced pertussis-specific CD4(+) T cell response in mice. To assess the effect of TLR4 ligation, Th type, quantity, and memory potential of pertussis-specific CD4(+) T cells were determined at the single-cell level after aP and aP+LpxL1 vaccination using intracellular cytokine staining and MHC class II tetramers. Adding LpxL1 to the aP vaccine weakened the Th2 component and strengthened the Th1/Th17 component of the specific CD4(+) T cell response. Notably, LpxL1 addition also induced higher frequencies of tetramer positive CD4(+) T cells in draining lymph nodes or blood, depending on the phase after vaccination. Moreover, there was a net profit in the number of CD4(+) T cells with a central memory phenotype, preferred for long-term immunity. Thus, adding a TLR4 ligand as adjuvant to a current aP vaccine was associated with a more favorable pertussis-specific CD4(+) T cell response.

Abstract
For a better understanding of the maintenance of immune mechanisms to Bordetella pertussis (Bp) in relation to age, we investigated the dynamic range of specific B cell responses in various age-groups at different time points after a laboratory confirmed pertussis infection. Blood samples were obtained in a Dutch cross sectional observational study from symptomatic pertussis cases. Lymphocyte subpopulations were phenotyped by flowcytometry before and after culture. Memory B (Bmem) cells were differentiated into IgG antibody secreting cells (ASC) by polyclonal stimulation and detected by an ELISPOT assay specific for pertussis antigens pertussis toxin (Ptx), filamentous haemagglutinin (FHA) and pertactin (Prn). Bp antigen specific IgG concentrations in plasma were determined using multiplex technology. The majority of subjects having experienced a clinical pertussis episode demonstrated high levels of both Bp specific IgG and Bmem cell levels within the first 6 weeks after diagnosis. Significantly lower levels were observed thereafter. Waning of cellular and humoral immunity to maintenance levels occurred within 9 months after antigen encounter. Age was found to determine the maximum but not base-line frequencies of Bmem cell populations; higher levels of Bmem cells specific for Ptx and FHA were reached in adults and (pre-) elderly compared to under-fours and schoolchildren in the first 6 weeks after Bp exposure, whereas not in later phases. This age effect was less obvious for specific IgG levels. Nonetheless, subjects' levels of specific Bmem cells and specific IgG were weakly correlated. This is the first study to show that both age and closeness to last Bp encounter impacts the size of Bp specific Bmem cell and plasma IgG levels.

Abstract
Pertussis is still occurring in highly vaccinated populations, affecting individuals of all ages. Long-lived Th1 CD4(+) T cells are essential for protective immunity against pertussis. For better understanding of the limited immunological memory to Bordetella pertussis, we used a panel of Pertactin and Pertussis toxin specific peptides to interrogate CD4(+) T cell responses at the epitope level in a unique cohort of symptomatic pertussis patients of different ages, at various time intervals after infection. Our study showed that pertussis epitope-specific T cell responses contained Th1 and Th2 components irrespective of the epitope studied, time after infection, or age. In contrast, the breadth of the pertussis-directed CD4(+) T cell response seemed dependent on age and closeness to infection. Multi-epitope specificity long-term after infection was lost in older age groups. Detailed knowledge on pertussis specific immune mechanisms and their insufficiencies is important for understanding resurgence of pertussis in highly vaccinated populations.

Abstract
Outer membrane vesicles (OMVs) have been extensively investigated as meningococcal vaccine candidates. Among their major components are the opacity (Opa) proteins, a family of surface-exposed outer membrane proteins important for bacterial adherence and entry into host cells. Many Opa-dependent interactions are mediated through the carcinoembryonic antigen-related cell adhesion molecule (CEACAM) family of receptors. Importantly, binding of Opa to CEACAM1 has been reported to suppress human CD4 T cell proliferation in vitro in response to OMV preparations. This raises the question whether OMV vaccines should contain Opa proteins at all. Until now it has been difficult to answer this question, as the proposed immunosuppressive effect was only demonstrated with human cells in vitro, while immunization experiments in mice are not informative because the Opa interaction is specific for human CEACAM1. In the present study we have used Opa+ and Opa- OMVs for immunization experiments in a human CEACAM1 transgenic mouse model. OMVs were prepared from a meningococcal strain H44/76 variant expressing the CEACAM1-binding OpaJ protein, and from an isogenic variant in which all opa genes have been inactivated. Both the CEACAM1 expressing transgenic mice and their congenic littermates lacking it were immunized twice with the OMV preparations, and the sera were analyzed for bactericidal activity and ELISA antibody titres. Total IgG antibodies against the OMVs were similar in both mouse strains. Yet the titres for IgG antibodies specific for purified OpaJ protein were significantly lower in the mice expressing human CEACAM1 than in the nontransgenic mice. No significant differences were found in bactericidal titres among the four groups. Overall, these data indicate that expression of human CEACAM1 confers a reduced Opa-specific antibody response in vivo without affecting the overall immune response against other OMV antigens.

Abstract
BACKGROUND Modulation of the host immune response by helminths has been reported to be essential for parasite survival and also to benefit the host by suppressing inflammatory diseases such as allergies. We have previously shown that excretory-secretory products of Trichinella spiralis muscle larvae have immunomodulatory properties and induce in vitro the expansion of CD4(+) CD25(+) FOXP3(+) Treg cells in a TGF-β-dependent manner. OBJECTIVE We aimed at determining the effect of the acute (intestinal) and the chronic (muscle) phase of T. spiralis infection on experimental allergic airway inflammation (EAAI) to Ovalbumin (OVA) and the involvement of Treg cells. METHODS The chronic phase was established before OVA-sensitization/challenge and the acute phase at two-time points, before and after OVA-sensitization. Mice were infected with 400 T. spiralis larvae and after euthanasia different pathological features of EAAI were measured. Adoptive transfer of CD4(+) T cells from Trichinella infected mice to OVA sensitized/challenged recipients was also performed. RESULTS We found that the chronic as well as the acute phase of Trichinella infection suppress EAAI as indicated by reduction in airway inflammation, OVA-specific IgE levels in sera, Th2-cytokine production and eosinophils in bronchoalveolar lavage. This protective effect was found to be stronger during the chronic phase and to be associated with increased numbers of splenic CD4(+) CD25(+) FOXP3(+) Treg cells with suppressive activity. Adoptive transfer of splenic CD4(+) T cells from chronically infected mice with elevated numbers of Treg cells resulted in partial protection against EAAI. CONCLUSIONS AND CLINICAL RELEVANCE These results demonstrate that the protective effect of T. spiralis on EAAI increases as infection progresses from the acute to the chronic phase. Here, Treg cells may play an essential role in the suppression of EAAI. Elucidating the mechanisms and molecular helminth structures responsible for this regulatory process is relevant to develop alternative tools for preventing or treating allergic asthma.

Abstract
Pneumoviruses such as pneumonia virus of mice (PVM), bovine respiratory syncytial virus (bRSV) or human (h)RSV are closely related pneumoviruses that cause severe respiratory disease in their respective hosts. It is well-known that T-cell responses are essential in pneumovirus clearance, but pneumovirus-specific T-cell responses also are important mediators of severe immunopathology. In this study we determined whether memory- or pre-existing, transferred virus-specific CD8+ T-cells provide protection against PVM-induced disease. We show that during infection with a sublethal dose of PVM, both natural killer (NK) cells and CD8+ T-cells expand relatively late. Induction of CD8+ T-cell memory against a single CD8+ T-cell epitope, by dendritic cell (DC)-peptide immunization, leads to partial protection against PVM challenge and prevents Th2 differentiation of PVM-induced CD4 T-cells. In addition, adoptively transferred PVM-specific CD8+ T-cells, covering the entire PVM-specific CD8+ T-cell repertoire, provide partial protection from PVM-induced disease. From these data we infer that antigen-specific memory CD8+ T-cells offer significant protection to PVM-induced disease. Thus, CD8+ T-cells, despite being a major cause of PVM-associated pathology during primary infection, may offer promising targets of a protective pneumovirus vaccine.

Abstract
NK cells play an important role in the early defense against invading pathogens. Although it is well established that infection leads to a substantial, local increase in NK cell numbers, little is known about the mechanisms that trigger their proliferation and migration. In this study, we investigated the dynamics of NK cell responses after intranasal respiratory virus infection. We show that NK cell numbers increased in the airways after influenza virus infection but find no evidence of proliferation either at the site of infection or in the draining lymph nodes. Instead, we find that the bone marrow (BM) is the primary site of proliferation of both immature and mature NK cells during infection. Using an adoptive transfer model, we demonstrate that peripheral, long-lived and phenotypically mature NK cells migrate back to the BM and proliferate there, both homeostatically and in response to infection. Thus, the BM is not only a site of NK cell development but also an important site for proliferation of long-lived mature NK cells.

Abstract
Natural killer (NK) cells are part of the innate immune system and contribute to the eradication of virus infected cells and tumors. NK cells express inhibitory and activating receptors and their decision to kill a target cell is based on the balance of signals received through these receptors. MHC class I molecules are recognized by inhibitory receptors, and their presence during NK cell education influences the responsiveness of peripheral NK cells. We here demonstrate that mice with reduced MHC class I cell surface expression, due to deficiency of immunoproteasomes, have responsive NK cells in the periphery, indicating that the lower MHC class I levels do not alter NK cell education. Following adoptive transfer into wild-type (wt) recipients, immunoproteasome-deficient splenocytes are tolerated in naive but rejected in virus-infected recipients, in an NK cell dependent fashion. These results indicate that the relatively low MHC class I levels are sufficient to protect these cells from rejection by wt NK cells, but that this tolerance is broken in infection, inducing an NK cell-dependent rejection of immunoproteasome-deficient cells.

Abstract
The 39- to 42-residue amyloid β (Aβ) peptide is deposited in extracellular fibrillar plaques in the brain of patients suffering from Alzheimer's Disease (AD). Vaccination with these peptides seems to be a promising approach to reduce the plaque load but results in a dominant antibody response directed against the N-terminus. Antibodies against the N-terminus will capture Aβ immediately after normal physiological processing of the amyloid precursor protein and therefore will also reduce the levels of non-misfolded Aβ, which might have a physiologically relevant function. Therefore, we have targeted an immune response on a conformational neo-epitope in misfolded amyloid that is formed in advance of Aβ-aggregation. A tetanus toxoid-conjugate of the 11-meric cyclic peptide Aβ(22-28)-YNGK' elicited specific antibodies in Balb/c mice. These antibodies bound strongly to the homologous cyclic peptide-bovine serum albumin conjugate, but not to the homologous linear peptide-conjugate, as detected in vitro by enzyme-linked immunosorbent assay. The antibodies also bound--although more weakly--to Aβ(1-42) oligomers as well as fibrils in this assay. Finally, the antibodies recognized Aβ deposits in AD mouse and human brain tissue as established by immunohistological staining. We propose that the cyclic peptide conjugate might provide a lead towards a vaccine that could be administered before the onset of AD symptoms. Further investigation of this hypothesis requires immunization of transgenic AD model mice.

Abstract
Influenza infections are responsible for significant morbidity and mortality each year, with the highest infection rates found in the elderly population. The main strategy to reduce the impact of influenza infections in the elderly population is vaccination. However, the efficacy of influenza vaccines that are licensed for use in the elderly is relatively low (17-53%). The complex age-related changes that occur in both innate and adaptive immunity are thought to hamper the immune response to influenza immunization and to reduce protection against infection in the elderly. For the development of improved vaccines that overcome the limitations of an aged immune system, it is crucial to understand the mechanisms that lead to immune dysfunction. Here, we review the recent progress in unravelling the mechanisms behind the age-related immune dysfunction in elderly, as well as the recent developments in improving influenza vaccines and identification of new correlates of protection.

Abstract
Neisseria meningitidis and Bordetella pertussis are Gram-negative bacterial pathogens that can cause serious diseases in humans. N. meningitidis outer membrane vesicle (OMV) vaccines and whole cell pertussis vaccines have been successfully used in humans to control infections with these pathogens. The mechanisms behind their effectiveness are poorly defined. Here we investigated the role of Toll-like receptor (TLR) 2 and TLR4 in the induction of immune responses in mice after immunization with these vaccines. Innate and adaptive immune responses were compared between wild type mice and mice deficient in TLR2, TLR4, or TRIF. TRIF-deficient and TLR4-deficient mice showed impaired immunity after immunization. In contrast, immune responses were not lower in TLR2−/− mice but tended even to be higher after immunization. Together our data demonstrate that TLR4 activation contributes to the immunogenicity of the N. meningitidis OMV vaccine and the whole cell pertussis vaccine, but that TLR2 activation is not required.

Abstract
The protective capacity of many currently used vaccines is based on induction of neutralizing antibodies. Many pathogens, however, have adapted themselves in different ways to escape antibody-based immune protection. In particular, for those infections against which conventional neutralizing antibody-based vaccinations appear challenging, CD8 T-cells are considered to be promising candidates for vaccine targeting. The design of vaccines that induce robust and long-lasting protective CD8 T-cell responses however imposes new challenges, as many factors such as kinetics and efficiency of antigen-processing and presentation by antigen presenting cells, T-cell repertoire and cytokine environment during T cell priming contribute to the specificity and functionality of CD8 T-cell responses. In the following, we review the most prominent aspects that underlie CD8 T-cell induction and discuss how this knowledge may help to improve the design of efficient CD8 T-cell inducing vaccines.

Abstract
Frequent occurrence of whooping cough in vaccinated populations suggests limited duration of vaccine-induced immunological memory. To investigate peculiarities in B cell memory specific for pertussis antigens P.69 pertactin (P.69 Prn), pertussis toxin (Ptx) and filamentous hemagglutinin (FHA), we monitored the induction and maintenance of specific serum IgG, long-lived bone marrow (BM)-derived plasma cell (PC) and splenic memory B cell (B(mem)) populations in a long-term preclinical vaccination model. Groups of BALB/c mice were primed and boosted (day 28) with a combined diphtheria (D), tetanus (T), acellular pertussis (aP) vaccine (DTaP) or whole cell pertussis (P) vaccine (DTP) and the immune status was followed over time. Levels of pertussis specific IgG, induced after primary and booster immunization, peaked at day 98 to decline thereafter. This was not paralleled by a decay, but rather an increase in BM resident specific PC, over time (>1 year). In contrast, splenic B(mem) peaked after booster immunization to decline till background levels. Late recall of immunological memory more than 1 year after primary and booster vaccination, however, did reveal a rapid proliferative response of pre-existing B(mem) but failed to evoke an anamnestic IgG response. A combination of waning P-antigen specific IgG production by PC and poor functions of the B(mem) compartment such as self-maintenance and anamnestic IgG responses could be a hallmark of waning pertussis immunity. A better understanding of the mechanisms of limited immunological memory to pertussis may help to improve current vaccines.

Abstract
Hepatitis B is a serious public health problem. Worldwide three different levels of hepatitis B endemicity (high, intermediate and low) can be distinguished. Areas with different levels of endemicity require tailored vaccination strategies to fit the needs for individuals at risk and/or countries, depending on the infection risk per age group, vaccination rate, duration of protection after vaccination, cost effectiveness of vaccination strategies and ease of implementation in the national immunization schedules.This opinion paper evaluates these factors and proposes a combination of infant risk group and universal adolescent vaccination for low endemic countries thus targeting the different groups at risk. A universal infant vaccination schedule starting with a newborn vaccination within 24h after birth is more appropriate in intermediate- and high-endemic regions.

Abstract
Historically, apart from hygiene, vaccination can be considered as one of the most successful accomplishments of public health in the 20th century. It has lead to some of the greater public health triumphs ever, including the eradication of naturally occurring smallpox and in the control of diseases such as polio. In addition there has been a significant reduction in disease burden imposed by measles, mumps, hepatitis, influenza, diphtheria, haemophilus influenza B and many other infections.

Abstract
The meningococcal class I outer membrane protein porin A plays an important role in the development of T cell-dependent protective immunity against meningococcal serogroup B infection and is therefore a major component of candidate meningococcal vaccines. T cell epitopes from porin A are poorly characterized because of weak in vitro memory T cell responses against purified Ag and strain variation. We applied a novel strategy to identify relevant naturally processed and MHC class II-presented porin A epitopes, based on stable isotope labeling of Ag. Human immature HLA-DR1-positive dendritic cells were used for optimal uptake and MHC class II processing of (14)N- and (15)N-labeled isoforms of the neisserial porin A serosubtype P1.5-2,10 in bacterial outer membrane vesicles. HLA-DR1 bound peptides, obtained after 48 h of Ag processing, contained typical spectral doublets in mass spectrometry that could easily be assigned to four porin A regions, expressed at diverging densities ( approximately 30-4000 copies/per cell). Epitopes from two of these regions are recognized by HLA-DR1-restricted CD4(+) T cell lines and are conserved among different serosubtypes of meningococcal porin A. This mass tag-assisted approach provides a useful methodology for rapid identification of MHC class II presented bacterial CD4(+) T cell epitopes relevant for vaccine development.

Abstract
Treosulfan is a water-soluble structural analog of busulfan, acting as a prodrug of alkylating epoxide species. It does not induce severe hepatotoxicity or veno-occlusive disease at or above the maximum tolerated dose, lacks significant nonhematological toxicity and has a limited organ toxicity. It is mainly indicated for the treatment of patients with ovarian cancer. In the present study, we report that permanent donor-specific tolerance and stable mixed multilineage chimerism can successfully be achieved across haploidentical MHC barriers when Treosulfan is administered in combination with anti-T-cell mAb and T-cell-depleted donor bone marrow cells. Furthermore, we show that less T-cell suppression is required when Treosulfan is included in the conditioning regimen. In conclusion, Treosulfan is a well-tolerated myeloablative agent with a low toxicity, and is a promising candidate drug for conditioning prior to bone marrow transplantation.

Abstract
Previously, we established a murine model, that involves the engraftment of fully allogeneic T cell depleted donor bone marrow cells in sublethally irradiated and single dose anti-CD3 treated recipient mice. These mice developed permanent stable multilineage mixed chimerism and donor-specific tolerance without graft-versus-host disease. Recently, we have shown that donor-specific tolerance is not induced and/or maintained by clonal anergy, neither by a Th1/Th2 shift, nor by suppressor or other regulatory processes. In the present study, we investigated whether clonal deletion plays a role in tolerance induction in our model. We studied the kinetics of TCRVbeta8(+) T cells in BALB/c (H-2L(d+))-->dm2 (H-2L(d-)) chimeras, in which combination of mouse strains TCRVbeta8 predominates the anti-donor response. We found that TCRVbeta8(+) T cells were specifically deleted. To our surprise, this deletion was also found in mixed chimeras, thymectomized prior to the conditioning regimen. We conclude that clonal deletion plays a role in the establishment and maintenance of donor-specific tolerance, and that the thymus is not required for this process. In addition, confocal laser-scanning microscopy clearly showed the presence of abundant amounts of donor T cells and some donor antigen presenting cells in the small intestine in thymectomized chimeras and not in other organs, suggesting that T cell selection might take place in this organ in the absence of the thymus.

Abstract
To investigate whether we could create a radiation-free conditioning regimen to induce permanent mixed and multilineage chimerism and donor-specific tolerance, we treated recipient mice with anti-T-cell antibodies, varying and fractionated doses of Treosulfan and fully MHC disparate bone marrow cells. Treosulfan is mainly used in the treatment of ovarian cancer. It is a structural analog of busulfan, but it does not induce severe hepatotoxicity or veno-occlusive disease at or above the maximum tolerated dose, lacks significant nonhematological toxicity and has limited organ toxicity. We report here the successful induction of permanent mixed multilineage chimerism and donor-specific tolerance as was proven by skin transplantation and IFN-gamma ELISPOT. In conclusion, because of its lower nonhematological toxicity, compared with other myeloablative regimens (eg irradiation or busulfan admin- istration), Treosulfan could be a better candidate for conditioning to induce donor-specific allograft tolerance.

Abstract
Limitations in neonatal natural killer (NK) cell responses may be associated with the less efficient newborn capacity to solve viral infections. Although these limitations have been extensively reported they are poorly characterized. Making use of the major histocompatibility complex (MHC) class I negative cell line K562, the parameters required for the initial events involved in neonatal NK/target cell interactions were determined and compared with adult blood NK cell/target cell interactions. Ultrastructural characterization of effector-target cell interactions revealed that neonatal NK cells are more strongly activated upon contact with K562 cells than adult blood NK cells. Furthermore, the neonatal capacity to establish contacts, in particular extensive contacts, is significantly reduced when compared with adult blood NK cells. However, no significant differences were found either in the cell surface expression levels or activation state of LFA-1, which could account for the reduced intercellular contacts. Because extensive contacts are crucial for effective immunologic synapse formation, these data suggest that a limited or nonsustained positive signaling may occur on neonatal NK cells, restricting their NK cell-mediated lysis capacity.

Abstract
Infectious agents have been implied as causative environmental factors in the development of autoimmunity. However, the exact nature of their involvement remains unknown. We describe a possible mechanism for the activation of autoreactive T cells induced by measles virus (MV) infection. The display of HLA-A*0201 associated peptides obtained from MV infected cells was compared with that from uninfected cells by mass spectrometry. We identified two abundant self peptides, IFI-6-16(74-82) and Hsp90beta(570-578), that were induced or upregulated, respectively, following infection. Their parental proteins, the type I interferon inducible protein IFI-6-16, and the beta chain of heat shock protein 90, have not been involved in MV pathogenesis. MV infection caused minor and major changes in the intracellular expression patterns of these proteins, possibly leading to altered peptide processing. CD8+ T cells capable of recognizing the self-peptides in the context of HLA-A*0201 were detectable at low basal levels in the neonatal and adult human T cell repertoire, but were functionally silent. In contrast, peptide-specific producing IFN-gamma producing effector cells were present in MV patients during acute infection. Thus, MV infection induces an enhanced display of self-peptides in MHC class I, which may lead to the temporary activation of autoreactive T cells.

Abstract
Following measles virus (MV) infection, viral peptides are presented to CTL by MHC class I molecules on infected antigen presenting cells at widely different epitope densities. Whereas three MV epitopes (MV-M(211-219), MV-F(438-446) and MV-H(30-38)) derived from different structural proteins occur at regular densities, one peptide derived from the non-structural C protein (MV-C(84-92)) fully dominates the MV peptide display in HLA class I molecules on end-stage-infected human B cells. Here we demonstrate that this hierarchy in MV epitope density is not a constant, but varies with progression of infection. While MV-M(211-219), MV-F(438-446) and MV-H(30-38) epitopes were already presented by HLA class I molecules early in infection, expression of MV-C(84-92) was restricted to the later phases of infection. These dynamics in epitope densities correlated with features of MV protein expression. Synthesis of C protein mainly focused towards the final stages of infection, while the other MV proteins were more readily synthesised from earlier time points on, in line with the emergence of their respective epitopes. Furthermore, the most abundant MV epitope was derived from the most unstable viral protein and vice versa, suggesting that the stability of viral proteins may be an indicator for the final abundance of their epitopes. Thus, even though many other factors may influence the generation of peptide-MHC class I complexes, we here report that the regulation of viral protein expression seems closely linked to the viral MHC class I epitope display. Finally, the observed dynamics in viral epitope hierarchy may have important implications for the induction of antiviral T cell immunity.

Abstract
Patients who are receiving an organ transplant nowadays are sentenced to the life-long administration of immunosuppressive drugs, which have serious side effects. The reliable induction of donor-specific tolerance therefore remains a major goal in organ transplantation. Previously, we have developed a sublethal, non-myeloablative murine model in which permanent mixed, multilineage chimerism and donor-specific tolerance are established. Our model involves engraftment of fully allogeneic T cell depleted donor bone marrow cells in low dose irradiated and anti-CD3 treated major histocompatibility complex (MHC)-disparate recipient mice. To investigate whether vascularized organ grafts are accepted in our model, we performed heterotopic heart transplantations in our mixed chimeric mice. Chimeric mice permanently accepted hearts from the bone marrow donor (>130 days) and rapidly rejected third party-type allografts (median survival time 9 days). Untreated control recipient mice rejected both donor- and third party-type allografts. In addition, mice that accepted their cardiac grafts, donor-specific acceptance of skin grafts was observed. In conclusion, the establishment of stable mixed chimerism with this low-toxicity regimen resulted in permanent donor-specific acceptance of vascularized organ as well as skin grafts across a full MHC barrier.

Abstract
Reactive arthritis (ReA) after infections with various gram-negative bacteria is strongly associated with the MHC class I molecule HLA-B27. It is supposed that the B27 molecule itself plays a role in the pathogenesis of ReA by presenting antigenic peptides to cytotoxic T lymphocytes. The peptide repertoires presented by Salmonella-, Shigella- and non-infected cells were compared to identify such peptides. From the peptides isolated from the B27 molecules of these cells, profiles were generated by reversed-phase chromatography and peaks present in the profiles from infected cells but not in profiles from non-infected cells were studied for their peptide compositions. Some sequences with identity to those in human histone H3, human ribosomal protein S17 and the heavy chain of HLA-B27 itself were detected only in profiles from infected cells. All peptides identified from infected cells contained the B*2705 peptide-binding motif. The data suggest that HLA-B27-positive cells infected with ReA-inducing bacteria show an increased presentation of certain self-peptides. There was no evidence for altered peptide-binding specificity of B27 after infection. However, the interpretations were hampered by the variation in peptide presentation between different experiments.
