Abstract
Summary
Oral tolerance is a physiological phenomenon described more than a century ago as a suppressive immune response to antigens that gain access to the body by the oral route. It is a robust and long-lasting event with local and systemic effects in which the generation of mucosally induced regulatory T cells (iTreg) plays an essential role. The idea of using oral tolerance to inhibit autoimmune and allergic diseases by oral administration of target antigens was an important development that was successfully tested in 1980s. Since then, several studies have shown that feeding specific antigens can be used to prevent and control chronic inflammatory diseases in both animal models and clinically. Therefore, oral tolerance can be classified as an antigen-specific form of oral immunotherapy (OIT). In the light of novel findings on mechanisms, sites of induction and factors affecting oral tolerance, this review will focus on specific characteristics of oral tolerance induction and how they impact in its therapeutic application.

Vaccination response to protein and carbohydrate antigens in patients with rheumatoid arthritis after rituximab treatment. Arthritis Res Ther 2010; 12:R111.

Abstract
Introduction Rheumatoid arthritis (RA) is frequently complicated with infections. The aim of our study was to evaluate vaccination response in patients with RA after B-cell depletion by using rituximab. Methods Influenza (Afluria) and pneumococcal polysaccharides (Pneumo23) vaccines were given 6 months after rituximab (post-RTX group, n = 11) or 6 days before rituximab treatment (pre-RTX group; n = 8). RA patients never exposed to RTX composed the control group (n = 10). Vaccine-specific cellular responses were evaluated on day 6 after vaccination, and vaccine-specific humoral responses, on day 21. Results On day 6 after vaccination, formation of influenza-specific B cells was lower in post-RTX group as compared with the pre-RTX group and controls (P = 0.04). Polysaccharide-specific B cells were found in 27% to 50%, being equally distributed between the groups. On day 21, the impairment of humoral responses was more pronounced with respect to influenza as compared with the pneumococcal vaccine and affected both IgG and light-chain production. Total absence of influenza-specific IgG production was observed in 55% of the post-RTX group. Conclusions RTX compromises cellular and humoral vaccine responses in RA patients. However, repeated RTX treatment or previous anti-tumor necrosis factor (anti-TNF) treatment did not accentuate these defects.

Abstract
Reactive arthritis can be triggered by inflammatory bowel diseases. We hypothesized that migration of mucosal immune cells from inflamed gut to joints could contribute to the development of reactive arthritis. Here we isolated gut-derived leukocytes from patients with Crohn's disease and ulcerative colitis. Using function-blocking mAbs and in vitro frozen section adhesion assays we studied whether these cells bind to synovial vessels and which molecules mediate the interaction. The results showed that mucosal leukocytes from inflammatory bowel diseased gut bind well to venules in synovial membrane. Small intestinal lymphocytes adhered to synovial vessels using multiple homing receptors and their corresponding endothelial ligands (CD18-ICAM-1, alpha(4)beta(7)/alpha(4)beta(1)-integrin-VCAM-1, L-selectin-peripheral lymph node addressins, and CD44). Of these, only ICAM-1 significantly supported binding of immunoblasts. In contrast, P-selectin glycoprotein ligand-1-P-selectin interaction accounted for practically all synovial adherence of mucosal macrophages. In addition, blocking of vascular adhesion protein-1 significantly inhibited binding of all these leukocyte subsets to joint vessels. We conclude that different leukocyte populations derived from inflamed gut bind avidly to synovial vessels using distinct repertoire of adhesion molecules, suggesting that their recirculation may contribute to the development of reactive arthritis in inflammatory bowel diseases.

Abstract
The presence of clonally-related B-lymphocyte aggregates within synovial lining tisue of rheumatoid arthritis (RA) patients suggests a germinal centre-like reaction, which may hold implications for disease pathogenesis and the causes of chronic inflammation. We studied 250 rheumatoid factor (RF) heavy-chain sequences cloned from the synovium of three patients with RA, to determine whether they undergo both somatic mutation and isotype switching consistent with this hypothesis. Size analysis of immunoglobulin heavy-chain cDNAs from synovial RF+ B cells revealed oligoclonal RF+ populations and identically-sized VH-D-JH transcripts of different immunoglobulin isotypes. Sequencing of individual inserts selected from cloned immunoglobulin heavy-chain cDNAs demonstrated a clonal relationship between immunoglobulin M (IgM) RF and IgA RF, suggesting that this isotype switch occurred in synovium. Furthermore, most somatic mutations were found to have occurred after this isotype switch. This finding suggests that the RA synovial microenvironment sustains somatic mutation and isotype switching in RF-specific B lymphocytes akin to secondary lymphoid organs.

Abstract
The expression of the mucosal lymphocyte integrin alphaEbeta7 and its ligand E-cadherin was analyzed in sialadenitic lesions of patients with Sjögren's syndrome in order to assess the potential interactions between the mucosal and the systemic immunological compartments. Immunohistochemical evaluation of the inflammatory infiltrates in the salivary gland tissues in Sjögren's syndrome patients revealed presence of alphaEbeta7-integrin-expressing lymphocytes, in 18 of 20 biopsies examined. The ligand for alphaEbeta7, E-cadherin was also found in 18 of 20 salivary gland biopsies analysed. These results suggest homing of lymphocytes derived from the gut epithelium through the blood stream to inflamed salivary gland tissue followed by in situ interaction with E-cadherin expressing cells, the ligand for alphaEbeta7 expressing T lymphocytes.

Abstract
OBJECTIVE To investigate the adhesion and extravasation capacity of peripheral blood mononuclear cells (PBMC) and the transport of bacterial antigens within these cells during Salmonella infection. METHODS Thirteen patients who were part of 2 outbreaks of Salmonella enteritidis infection were included in this study. The capacity of PBMC from these patients to bind to vascular endothelium in inflamed synovium was tested using a Stamper-Woodruff-type frozen-section assay. The same cells were studied for the presence of Salmonella antigens by immunofluorescence staining. The transendothelial migration of mononuclear cells containing Salmonella or its components through unstimulated endothelial cell layer was quantified. RESULTS The capacity of PBMC to adhere to synovial vessels was significantly increased during Salmonella infection (P=0.0003). Monocytes had a transiently high adhesive state between 2 and 5 weeks after the patients had eaten the contaminated food. The cells containing Salmonella antigens were concentrated in the transmigrated population. CONCLUSION During acute Salmonella infection the increased binding of PBMC to vascular endothelium in inflamed synovium and enhanced transmigration of PBMC containing Salmonella may be the key factors leading to transport of bacterial antigens through the endothelial barrier and initiation of arthritis in susceptible individuals.

Abstract
The results from our previous study showed IgA dominated ASC responses to pneumococcal polysaccharide vaccine and to pneumococcal polysaccharide meningococcal outer membrane protein conjugate vaccine (PncOMPC) in adult volunteers. The results indicated that a high IgA ASC response is a useful indicator of a secretory IgA response in saliva. We believe that the mucosal immune responses is potentially an important characteristic of the pneumococcal vaccines and should thus be measured when the new pneumococcal conjugate vaccines are evaluated. In the present study, we studied two new tetravalent pneumococcal conjugate vaccines: the diphtheria toxoid and tetanus toxoid conjugates. In contrast to PncOMPC, these conjugates induced higher responses than the polysaccharide vaccine. Furthermore, the different structure of the two conjugate vaccines might affect the nature of the response. Thus a different vaccine may be optimal for induction of a mucosal response than is of systemic responses.

Abstract
Naive lymphocytes patrol continuously between the blood and different lymphatic tissues to sample the whole body for foreign antigens. During inflammation, leukocyte recruitment into tissue is enhanced to promote the recruitment of a range of effector cells into the affected area. The complex recirculatory pathways that underlie this process are governed by adhesion receptors on blood-borne leukocytes and by their specific ligands expressed on the luminal aspect of endothelial cells lining the vessels. Gut-associated lymphatic tissues are positioned strategically at the major port of entry for foreign antigens. They form a functionally unified entity that utilizes both the afferent and efferent arms of the immune response to respond to the large array of antigens entering via the gut under normal conditions as well as during inflammation. Once antigens have been absorbed from the gut, they may enter the portal vein and the liver where the immune response can be further regulated by the resident immune cells of the liver. Thus the gut and liver form an important barrier to enteral antigens, and leukocyte recruitment to these sites will need to be carefully regulated to ensure effective immune surveillance. In this article, we describe the current concepts of lymphocyte adhesion in these two organs as revealed by animal models. Subsequently, we discuss how well these principles apply to the lymphocyte-endothelial cell interactions in humans and what additional insights can be obtained from human studies.

Abstract
Antibody-secreting cells (ASC) and serum antibody response were measured in 15 adult volunteers immunized subcutaneously with group A and C meningococcal polysaccharide vaccine. The vaccine induced an IgA-dominated ASC response both to meningococcal group A (Men A) and group C (Men C) polysaccharides suggesting an activation of mucosa-committed B cells. Also the relative increase in serum IgA antibodies was higher than in IgC or IgM antibodies. The results support earlier studies showing that the T-cell independent polysaccharide antigens induce an IgA dominated antibody response and a mucosal response may be induced also by systemic administration.

Abstract
Integrin-adressin binding is a critical step in lymphocte attachment to target tissues. The mucosal recognition systems (alpha E beta 7, alpha 4 beta 7, MADcam-1) have been implicated in the autoimmune process in rheumatoid arthritis. We developed a model for in vivo study of radio-labelled lymphocyte circulation and their attachment to human rheumatoid synovium. We studied the homing of tonsil lymphocytes, considered as mucosal lymphocytes, and the involvement of alpha E beta 7 integrin and LFA1 in the homing of tonsil lymphocytes. We engrafted human rheumatoid synovium subcutaneously in 6 week old SCID CB17 mice. Three weeks later, we injected intraperitoneally 20 IO6 human peripheral blood or tonsil mononuclear cells, previously labelled with 3 mCFi HMPAO-99mTc. A mouse total body scintigram was obtained 20 h postinjection. The same protocol was performed after treatment of the MNC and mAb against LFA-1 (CD11a) or alpha E beta 7 (CD103). Tonsil MNC retention in the rheumatoid synovial graft 20 h post-injection was enhanced compared to blood MNC (12731 +/- 8297cpm/200 pixel) versus 5982 +/- 4713cpm/200 pixel, p < 0.05). A monoclonal antibody against LFA 1 decreased the activity in the graft (4152 +/- 1287 cpm/200 pixel), p < 0.05. No significant difference in tonsil MNC attachment to rheumatoid synovial tissue was observed with a mAb against alpha E beta 7 (8057 +/- 5009 cpm/200 pixel). Our results showed an increase in radiolabelled mucosal MNC migration in synovial tissue engrafted in SCID mice compared with blood MNC. Moreover, the date suggest that LFA-1 but not the alpha E beta 7 integrin is involved in tonsil MNC binding to synovial tissue in RA.

Abstract
OBJECTIVE To study the effects of sulphasalazine (SASP) on the systemic and mucosal humoral immune systems in patients with rheumatoid arthritis (RA). METHODS Serum concentrations of interleukin 6 (IL-6), class and subclass specific IgG, IgA and IgM, IgA and IgG antigliadin antibodies and rheumatoid factors (RF) of IgG, IgA (including IgA1 and IgA2 subclasses) and IgM isotypes were measured before and 16 weeks after sulphasalazine (SASP) therapy in 15 female and three male patients with RA. Amounts of immunoglobulins in saliva and jejunal fluid were measured as estimates of mucosal humoral immunity. RESULTS Serum concentrations of IgA and IgG decreased significantly during SASP therapy and correlated with reduced concentrations of IL-6. In addition, levels of circulating IgA RF, IgA anti-gliadin antibodies and IgM RF decreased significantly after the treatment. In contrast, immunoglobulin levels in saliva and jejunal fluid were unaltered. CONCLUSION SASP exerts powerful but selective inhibitory effects on systemic immunoglobulin production, whereas no effects on mucosal immunoglobulin production were observed. The decreased systemic B cell activity may be mediated by downregulation of the production of IL-6, a cytokine with Ig switching properties.
