Abstract
Oral tolerance is the physiological process that enables the immune system to differentiate between harmless dietary and microbiota antigens from pathogen derived antigens. It develops at the mucosal surfaces and can result in local and systemic regulatory and anti-inflammatory effects. Translation of these benefits to the clinical practice faces limitations involving specificity and doses of antigen as well as regimens of feeding. To circumvent these problems, we developed a recombinant Hsp65 delivered by the acid lactic bacteria Lactococcus lactis NCDO 2118 directy in the intestinal mucosa. Hsp65 is a ubiquitous protein overexpressed in inflamed tissues and capable of inducing immunoregulatory mechanisms. L. lactis has probiotic properties and is commonly and safely used in dairy products. In this study, we showed that continuous delivery of HSP65 in the gut mucosa by L. lactis is a potent tolerogenic stimulus inducing regulatory CD4+LAP+ T cells that prevented collagen-induced and methylated bovine serum albumin-induced arthritis in mice. Clinical and histological signs of arthritis were inhibited as well as levels of inflammatory cytokines such as IL-17 and IFN-γ, serum titers of anti-collagen antibodies and rheumatoid factor. Oral administration of L. lactis induced alterations in microbiota composition toward an increased abundance of anaerobic bacteria such as Bifidobacterium and Lactobacillus. Tolerance to HSP65 and arthritis prevention induced by the recombinant L. lactis was associated with increase in IL-10 production by B cells and it was dependent on LAP+ T cells, IL-10 and TLR2 signaling. Therefore, HSP65-producing treatment induced effective tolerance and prevented arthritis development suggesting it can be used as a therapeutic tool for autoimmune diseases.

Abstract
INTRODUCTION Leptin is a cytokine-like hormone which has a complex role in inflammation. However, the importance of leptin in the pathogenesis of rheumatoid arthritis (RA) is far from being fully elucidated. The aim of the study was to determine serum leptin levels in RA patients and to evaluate whether there is an association between disease activity, anthropometric indices and leptin levels. MATERIAL AND METHODS This hypothesis-generating study included 55 RA patients and 25 matched healthy subjects. The serum leptin concentration was determined by enzyme-linked immunosorbent assay (ELISA). RESULTS Median serum leptin level in RA patients of 27.4 ng/ml (14.5-54.9 ng/ml) was statistically significantly higher (p = 0.03) compared with the median leptin value of 16.3 ng/ml (9.6-38.8 ng/ml) determined in healthy controls. The serum leptin level in the high disease activity group was significantly higher (p < 0.0005) than that in the low disease activity group and in healthy controls. A significant difference (p = 0.001) in serum leptin level was also found when the high disease activity group was compared with the moderate disease activity group. In the RA group a statistically significant positive correlation (rho = 0.390; p = 0.003) was observed between serum leptin level and disease activity score (DAS28). CONCLUSIONS The present results show that serum leptin levels are increased and significantly associated with disease activity in patients with RA and may have a valuable role in the inflammatory reactions and pathogenesis of RA.

Abstract
BACKGROUND Phthalimide analogs have been shown to exhibit anti-inflammatory, analgesic and immunomodulatory activities in different preclinical assays. This study aimed to investigate the potential role of 2-phthalimidethanol (PTD-OH) and 2-phthalimidethyl nitrate (PTD-NO) in a murine model of antigen-induced articular inflammation. METHODS Articular inflammation was induced by intra-articular injection of methylated bovine serum albumin (mBSA) in the knee joint of immunized male C57BL/6J mice. The animals were pre-treated with PTD-OH or PTD-NO (500mg/kg, per os, - 1h). Nociceptive threshold was measured using an electronic von Frey apparatus. The total number of leukocytes in the synovial cavity was determined. Concentrations of tumor necrosis factor (TNF)-α and CXCL-1 and myeloperoxidase (MPO) activity were determined in periarticular tissue. RESULTS Both PTD-OH and PTD-NO inhibited at similar extent the mechanical allodynia, neutrophil recruitment to the synovial cavity and periarticular tissue and TNF-α and CXCL-1 production induced by intra-articular challenge with mBSA in immunized mice. CONCLUSIONS PTD-OH and PTD-NO exhibit a marked activity in a murine model of antigen-induced articular inflammation in immunized animals. These results reinforce the interest in the investigation of phthalimide analogs devoid of the glutarimide ring as candidates to analgesic and anti-inflammatory drugs.

Abstract
Oral immunotherapy (OIT) is a promising therapeutic approach for treating food allergy. Past studies have shown that OIT reduces allergic response only in severe allergy model mice. We worked to establish mild allergy model mice, and investigated whether 'rush' OIT for 10 d improved the allergic response and biomarkers in these mice. Balb/c mice were sensitized to ovomucoid (OM) in alum. The rush OIT was done for 10 d. Oral OM challenge was used to determine the impact of OIT on the allergic response. We measured allergic biomarkers, such as vascular permeability in the skin, plasma levels of total IgE, OM-specific IgE, IgG1 and IgG2a and cytokines in splenocyte culture supernatant. OIT for 10 d did not improve allergy symptoms and increased vascular permeability. Total IgE in the plasma of OIT-treated mice was significantly higher than in that of non-treated mice. OM-specific IgG1 and IgG2a plasma levels were not significantly different between OIT-treated and non-treated mice. Among the cytokine secretion of splenocyte from OIT-treated mice, IFN-γ and IL-10 were significantly lower than in non-treated mice, and IL-4 and IL-5 were significantly higher. Total TGF-β in the OIT-treated group was not detected. The IFN-γ/IL-4 ratio of the OIT-treated group was about 1/8 that of the non-treated group. OIT for 10 d was not effective and some biomarkers showed negative responses in the mild allergy model mice. We suggest OIT should be used very carefully as this treatment carries a risk of worsening allergy symptoms for mice with mild allergy.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a very complicated autoimmune disease with apparent synovial hyperplasia and cartilage and bone destruction. AIMS In the present study, we aimed to determine whether the pathogenesis of RA correlates with food allergy and which allergen(s) are relevant. MATERIALS AND METHODS We used type-II collagen (CII) to induce arthritis (collagen-induced arthritis, CIA) model in Wistar rats, and the development of arthritis was evaluated accordingly by scoring system. Proinflammatory cytokine levels in plasma were measured by enzyme-linked immunosorbent assay (ELISA), and concentrations of circulating immune complexes (CICs) were analyzed by C1q solid phase method. Furthermore, food-specific immunoglobulin G (IgG) and immunoglobulin E (IgE) levels were determined in the CIA model. RESULTS In the CIA model, we found that levels of tumor necrosis factor-alpha (TNF-a), interleukin (IL)-1, IL-6, and IL-17, as well as CICs, were elevated significantly. Moreover, concentrations of milk- or egg-specific IgG and IgE were enhanced strikingly in CIA rats. CONCLUSION The results suggest that pathogenesis of RA correlates closely to increased egg- or milk-specific antibodies.

Prolonged ingestion of ovalbumin diet by sensitized mice improves the metabolic consequences induced by experimental food allergy. Clin Exp Immunol 2015; 178:416-27.

Abstract
The prevalence of food allergy is rising in the western world. Allergen restriction is the chosen treatment in this condition, but continuous ingestion of the antigen has shown positive results in clinical trials. In a previous study, we have shown several allergic and metabolic alterations after 7 days of ovalbumin (OVA) ingestion by sensitized mice. The aim of this study was to investigate whether prolonged ingestion of antigen by sensitized mice would reverse the metabolic consequences caused by experimental food allergy. For this, allergic and metabolic parameters were analysed after prolonged ingestion of an OVA diet by OVA-sensitized mice. As shown previously, after 7 days of OVA consumption, sensitized mice showed increased serum levels of anti-OVA immunoglobulin (Ig)E and IgG1, aversion to the antigen ingestion, marked body and adipose tissue weight loss, followed by adipose tissue inflammation and decreased serum levels of adipokines, glucose and triglycerides. However, after 14 days of oral challenge, sensitized mice showed an anti-OVA IgE level similar to the mice that were only sensitized, but the specific IgG1 did not change. With this prolonged ingestion of OVA, sensitized mice were protected from OVA-induced anaphylaxis when the antigen was given systemically at a dose of 2 mg/animal. Moreover, various parameters analysed were significantly ameliorated, including adipose tissue inflammation, body and adipose tissue loss, as well as serum levels of adipokines and triglycerides. Therefore, our data suggest that prolonged ingestion of OVA by sensitized mice results in an improvement of the metabolic consequences caused by experimental food allergy.
