Abstract
Oral cholera vaccination is used to induce immune responses in the intestines to protect against cholera infection. However, oral vaccination may also affect immune responses in other mucosal tissues. To study this, tissue-specific homing potential and kinetics of B-cell responses were characterized after oral cholera vaccination. Healthy adult volunteers received two doses of Dukoral® and blood, saliva, nasal wash, and fecal samples were collected over time to detect vaccine-specific antibodies. Additionally, homing potential of lymphocytes to small intestine, colon, airways, skin, and periphery was measured by expression of Integrin β1 and β7, CCR9, CCR10, CCR7, and CLA. After vaccination, antibody responses to cholera toxin B (CTB) and Dukoral® were detected in serum and nasal wash. CTB-specific memory B cells in peripheral blood and tissue homing profiles of memory B cells peaked at day 18. IgA+ memory B cells expressed markers that enable homing to the airways and colon, while IgA- memory B cells primarily expressed small-intestine-homing markers. These data show that oral cholera vaccination has a differential effect on immune responses in various mucosal sites, including the respiratory tract.

Abstract
AIMS/HYPOTHESIS Impaired intestinal barrier function is observed in type 1 diabetes patients and animal models of the disease. Exposure to diabetogenic antigens from the intestinal milieu due to a compromised intestinal barrier is considered essential for induction of the autoimmune process leading to type 1 diabetes. Since a hydrolysed casein (HC) diet prevents autoimmune diabetes onset in diabetes-prone (DP)-BioBreeding (BB) rats, we studied the role of the HC diet on intestinal barrier function and, therefore, prevention of autoimmune diabetes onset in this animal model. METHODS DP-BB rats were fed the HC diet from weaning onwards and monitored for autoimmune diabetes development. Intestinal permeability was assessed in vivo by lactulose-mannitol test and ex vivo by measuring transepithelial electrical resistance (TEER). Levels of serum zonulin, a physiological tight junction modulator, were measured by ELISA. Ileal mRNA expression of Myo9b, Cldn1, Cldn2 and Ocln (which encode the tight junction-related proteins myosin IXb, claudin-1, claudin-2 and occludin) and Il-10, Tgf-ß (also known as Il10 and Tgfb, respectively, which encode regulatory cytokines) was analysed by quantitative PCR. RESULTS The HC diet reduced autoimmune diabetes by 50% in DP-BB rats. In DP-BB rats, prediabetic gut permeability negatively correlated with the moment of autoimmune diabetes onset. The improved intestinal barrier function that was induced by HC diet in DP-BB rats was visualised by decreasing lactulose:mannitol ratio, decreasing serum zonulin levels and increasing ileal TEER. The HC diet modified ileal mRNA expression of Myo9b, and Cldn1 and Cldn2, but left Ocln expression unaltered. CONCLUSIONS/INTERPRETATION Improved intestinal barrier function might be an important intermediate in the prevention of autoimmune diabetes by the HC diet in DP-BB rats. Effects on tight junctions, ileal cytokines and zonulin production might be important mechanisms for this effect.

Abstract
BACKGROUND Previously, we reported that exclusive breastfeeding delayed and partially protected bio-breeding diabetes-prone (BBDP) rats from spontaneous autoimmune diabetes development. To investigate whether this protection results from modulation of the (mucosal) immune system, the present study was designed to analyse the effect of nutrition early in life on the immune status of BBDP rats. METHODS The breastfeeding period of BBDP pups was extended or not, while allowing half of the pups to eat during that period whereas the other half received only breast milk. Cytokine profiles as well as naturally occurring regulatory T-cell frequencies were measured over time in the mesenteric lymph nodes (MLNs) and spleen. RESULTS Prolonged exclusive breastfeeding partially protects against autoimmune diabetes development and resulted in elevated levels of natural regulatory T cells (CD4(+) CD25(+) FoxP3(+)) in MLNs and spleen directly after weaning and throughout life. Stimulation of MLN cells from rats that ingested solid food during the nursing period showed massive secretion of interferon gamma (IFN-gamma), interleukin (IL)-4 and IL-10, whereas MLN cells from exclusive breastfed rats did not. In contrast, transforming growth factor beta (TGF-ss) was secreted equally by all groups. CONCLUSIONS Prolonged exclusive breastfeeding partially protects BBDP rats from autoimmune diabetes development. Interestingly, ingestion of solid food during the weaning period completely abolishes this protective effect. The protective effect of exclusive breastfeeding correlates with higher levels of naturally occurring regulatory T cells throughout life and low cytokine secretion at weaning.

Abstract
AIMS/HYPOTHESIS Accumulating data suggest that the gut immune system plays a role in the development of type 1 diabetes. The intestinal flora is essential for the development of the (gut) immune system and the establishment of tolerance. It has been reported that oral administration of food and bacterial antigens early in life suppresses later development of diabetes in the Bio-Breeding diabetes-prone (BB-DP) rat. This study was designed to investigate the possible relationship between the development of diabetes and the composition of intestinal flora. MATERIALS AND METHODS The intestinal flora of BB-DP rats, a rat model for type 1 diabetes, was characterised long before the clinical onset of diabetes by fluorescent in situ hybridisation. In a separate experiment, BB-DP rats were treated with antibiotics and the effect on diabetes incidence and level of insulitis was analysed. RESULTS We observed a difference in bacterial composition between rats that eventually did and those that did not develop diabetes. This difference was detectable long before clinical onset of the disease. Rats that did not develop diabetes at a later age displayed a lower amount of Bacteroides sp. Modulation of the intestinal flora through antibiotic treatment decreased the incidence and delayed the onset of diabetes. A combination of antibiotic treatment and a protective hydrolysed casein diet completely prevented diabetes in the BB-DP rat. CONCLUSIONS/INTERPRETATION Our data suggest that the intestinal flora is involved in the development of type 1 diabetes. Factors influencing composition of the intestinal flora could be a target for therapeutic intervention.

Abstract
AIMS/HYPOTHESIS Environmental factors such as diet and bacterial antigens play an important role in the onset of Type 1 diabetes. Different self-antigens are suggested to play a role in the development of diabetes. Antibodies against the 60-kDa heat shock protein 60, which have a high homology to bacterial heat shock protein 65, have been found in the circulation at the onset of diabetes in humans and in pre-diabetic NOD-mice. One of the immunodominant epitopes in autoimmune diabetes is p277, a specific peptide of human heat shock protein 60 corresponding to positions 437-460. In this study we investigated whether neonatal oral administration of DiaPep277 (a synthetic peptide analogue of p277) affected the development of diabetes in the BioBreeding-Diabetes Prone (BB-DP) rat, and whether this could potentiate the effect of a protective hydrolysed casein-diet. METHODS BB-DP rats were orally inoculated once per day with placebo or DiaPep277 at days 4, 5, 6 and 7 of life. At the age of 21 days rats were weaned on to a conventional, cereal-based diet or on to the hydrolysed casein-diet. RESULTS The development of diabetes in animals receiving DiaPep277 in combination with the hydrolysed casein-diet was delayed by 17 days, and a relative reduction of the incidence by 64% was seen. Non-diabetic animals did not show any sign of insulitis. CONCLUSIONS/INTERPRETATION Short-term neonatal feeding with p277 in early life, combined with diet adaptation, appears to provide a procedure to significantly reduce the development of Type 1 diabetes in later life.

Abstract
Agouti-related protein (AgRP) is an endogenous antagonist at the melanocortin 3 and 4 receptor in the hypothalamus. Central administration of AgRP produces a robust increase in food intake, and this effect can be blocked by administration of nonspecific opioid receptor antagonist. Such results implicate opioid receptors as critical to mediating the effects of AgRP. To determine which opioid receptor subtype is critical, we first determined the highest i3vt (administered into the third ventricle) dose of two specific opioid antagonists, nor-Binaltorphine or beta-funaltrexamine, that did not influence food intake on their own. Then, rats were pretreated with either of these two antagonists before i3vt AgRP and access to a high-fat diet. For neither the kappa- nor the micro -specific antagonist was there any effect to block the effects of AgRP on food intake. However, administration of both the kappa- and micro -receptor antagonists does significantly reduce the effect of AgRP. The current results implicate opioid receptors as critical downstream mediators of the potent effects of AgRP to increase food intake but indicate that either micro - or kappa-receptor activation is sufficient for AgRP's effect.

Abstract
Vocal cord dysfunction (VCD) is a respiratory disorder often confused with asthma. Although previous case reports have implicated family and/or individual psychopathology in the etiology of this condition, this is the first paper to present prospective, case-control empirical data on a group of pediatric patients with VCD. A case-control methodology was employed to examine patients in terms of both family and individual functioning. Results indicate that patients with VCD were not different from asthmatic controls on measures of family functioning. However, they did experience significantly higher levels of anxiety and received a higher number of anxiety-related diagnoses such as separation anxiety and generalized anxiety disorder on a structured psychiatric interview. The nature of the relation between VCD and psychological symptoms in children is discussed. Etiologic and treatment issues are examined in the context of the findings.

Abstract
BACKGROUND The relationship between severe reactive airway disease (RAD) and gastroesophageal reflux disease (GERD) has been noted but the relationship is poorly understood. This study reports our experience with laparoscopic fundoplication and its effect on the pulmonary status of children with severe steroid-dependent reactive airway disease. METHODS Fifty-six patients with severe steroid-dependent RAD and medically refractory GERD underwent laparoscopic Nissen fundoplications. Mean age was 7 years and mean weight was 20 kg. All patients had the procedure completed successfully laparoscopically with an average operative time of 62 min. Average hospital stay was 1.6 days. RESULTS Forty-eight of 56 patients noted significant improvement in their respiratory symptoms in the first week. Fifty of 56 patients have been weaned off their oral steroids and four others have had a greater than 50% decrease in their dose. Sixteen patients had a documented increase in their FEV1 in the initial postoperative period (avg. 26%). CONCLUSION Patients with steroid-dependent RAD and GERD refractory to medical management show improvement in their respiratory status following fundoplication and the majority can be weaned off of their oral steroids. Laparoscopic techniques allow this procedure to be performed safely even in this high-risk group of patients.
