BACKGROUND: Compositional changes of the early life gut microbiota have been implicated in IgE-associated allergic disease but there is lack of longitudinal studies. We examined gut microbiota development from infancy to school age in relation to onset of IgE-associated allergic diseases. At 8 years of age, we also examined the relationship between gut microbiota and T-cell regulation, estimated as responses to polyclonal T-cell activation. METHODS: Stool samples were collected from 93 children at 4, 6 and 13 months, and 8 years of age...

BACKGROUND: Commensal flora are involved in the appropriate development of the mature immune system. However, it is unclear how commensal flora contribute to immune responses against periodontal pathogens, including the response to lipopolysaccharide (LPS). The purpose of this study was to evaluate the expression of immune responses after topical application of LPS in germ-free (GF) and specific-pathogen-free (SPF) mice. METHODS: GF and SPF mice at 8 weeks of age were randomly divided into four groups each: a baseline group (n = 4/group) and three experimental groups (n = 6/group)...

Cancer metastatic spread to serous cavity causes malignant pleural effusions (MPEs), indicating dismal prognosis. Tumor microenvironment can implement suppressive activity on host immune responses. Thus, we investigated the prevalence of Tregs and the relationship between them and TGF- β and IL-10 concentrations and measured expression of FOXP3 , CTLA-4 , CD28 , and GITR genes, as well as protein expression of selected genes in benign effusions and MPEs. The percentage of Tregs was determined by means of multicolor flow cytometry system...

BACKGROUND: Thrombomodulin (TM) is a promising therapeutic natural anti-coagulant, which exerts the effects to control disseminated intravascular coagulation. However, little is known whether TM on micro-vessels could play an important role in the regulation of intimal hyperplasia. We investigated the vessel-protective effect of TM in the survival of fully major histocompatibility complex (MHC)-mismatched murine cardiac allograft transplantation. METHODS: CBA recipients transplanted with a C57BL/6 heart received intraperitoneal administration of normal saline or 0...

Although it has been recognized that intestinal bacteria play an important role in the pathology of human ulcerative colitis (UC), specific pathogenic bacteria for UC have not been identified. We investigated the influence of Paraclostridium bifermentans PAGU1678 strain on the pathology of a UC mouse model and found it increased UC pathosis scores such as loose and bloody stools, reduced diversity of fecal flora, disappearance of the crypt structure of distal colon tissue, destruction of intestinal epithelial cells, and atrophy of the colon...

BACKGROUND: Epicutaneous immunotherapy (EPIT) is a promising method for treating food allergies. In animal models, EPIT induces sustained unresponsiveness and prevents further sensitization mediated by Tregs. Here, we elucidate the mechanisms underlying the therapeutic effect of EPIT, by characterizing the kinetics of DNA methylation changes in sorted cells from spleen and blood and by evaluating its persistence and bystander effect compared to oral immunotherapy (OIT). METHODS: BALB/c mice orally sensitized to peanut proteins (PPE) were treated by EPIT using a PPE-patch or by PPE-OIT...

Sepsis is characterized by the extensive release of cytokines and other mediators. It results in a dysregulated immune response and can lead to organ damage and death. Curcumin has anti-inflammatory properties and immunoregulation functions in various disorders such as sepsis, cancer, rheumatoid arthritis, cardiovascular diseases, lung fibrosis, gallstone formation, and diabetes. This paper investigates the effects of curcumin on immune status and inflammatory response in mice subjected to cecal ligation and puncture (CLP)...

Bacterial contamination of the uterus following calving is ubiquitous in the dairy cow, 40% of cows develop postpartum uterine infection, including metritis. While predisposing factors like twinning and dystocia are associated with metritis, it is unclear why some cows remain healthy following calving and others develop uterine infection, negatively impacting animal health, milk production and economic return. Here, we profiled peripheral blood mononuclear cells of cows before calving and during postpartum metritis...

A considerable amount of knowledge on natural and anthropogenic pathologic conditions affecting different cetacean species has been gained over the last decades. Nonetheless, the immunopathological bases for most of these processes have been poorly documented or remain unknown. Comparative immunopathological investigations in these species are precluded by the limited number of specific antibodies, most of which are not commercially available, and the reduced spectrum of validated and/or cross-reactive ones...

In this study, we administered specially developed chitosan/alginate nanoparticle encapsulated BV (CH/AL-BV) which has slow-releasing properties and mucosal adhesiveness to pig via nasal route and evaluate whether it can facilitate systemic immune response and improve clearance of porcine reproductive and respiratory syndrome virus (PRRSV). The CH/AL-BV-administered group with PRRSV vaccination showed significantly enhanced Th1-related responses including a high population of CD4+ T lymphocyte and cytokine mRNA levels including interferon-gamma (IFN-γ) and interleukin (IL)-12 and increased PRRSV-specific IgG levels...

AIMS: Enteroviruses, especially coxsackieviruses B (CV-B), have been associated with the pathogenesis of type 1 diabetes (T1D). An anti-CV-B4 neutralizing activity in saliva of T1D patients was previously reported. Our aim was to study the association between the saliva anti-CV-B4 neutralizing activity and immune parameters in T1D patients in comparison with non-diabetic individuals. METHODS: Saliva and blood samples were collected from 15 T1D patients and 8 controls...

Background: Eosinophilic esophagitis (EoE) is an antigen-driven disease mediated by an abnormal immune Th2 response. Objective: The objective of this article is to investigate genes associated with regulating immune responses leading to disease susceptibility. Methods: Twenty-seven tag single nucleotide polymorphisms (tSNPs) selected in five candidate genes ( TLR3, TLR4, FOXP3, FLG and TSLP ) were genotyped in 218 EoE patients and 376 controls...

Background: Non-infectious uveitis can cause chronic relapsing and remitting ocular inflammation, which may require high dose systemic immunosuppression to prevent severe sight loss. It has been classically described as an autoimmune disease, mediated by pro-inflammatory Th1 and Th17 T-cell subsets. Studies suggest that natural immunosuppressive CD4+ CD25+ FoxP3+ T-regulatory cells (Tregs) are involved in resolution of inflammation and may be involved in the maintenance of clinical remission...

Dendritic cells (DC) are important in the onset and severity of inflammatory bowel disease (IBD). Tolerogenic DC induce T-cells to become therapeutic Foxp3+ regulatory T-cells (Tregs). We therefore asked if experimental IBD could be prevented by administration of bone marrow-derived DC generated under conventional GM-CSF/IL-4 conditions but in the presence of a mixture of antisense DNA oligonucleotides targeting the primary transcripts of CD40, CD80, and CD86. These cell products (which we call AS-ODN BM-DC) have demonstrated tolerogenic activity in preventing type 1 diabetes and preserving beta cell mass in new-onset type 1 diabetes in the NOD mouse strain, in earlier studies...

FOXP3 promotes the development and function of regulatory T cells mainly through regulating the transcription of target genes. RNA alternative splicing has been implicated in wide range of physiological and pathophysiological processes. We report here that FOXP3 associates with Heterogeneous Nuclear Ribonucleoprotein (hnRNP) F through the exon 2 encoded region of FOXP3 and the second quasi-RNA recognition motif (qRRM) of hnRNPF. FOXP3 represses the ability of hnRNPF to bind to its target pre-mRNA and thus modulates RNA alternative splicing...

BACKGROUND/AIMS: This study aimed to explore whether the adoptive transfusion of autologous CD4+CD25+ regulatory T cells (CD4+CD25+ Tregs) has a therapeutic effect on Experimental autoimmune neuritis (EAN) model rats, and it provides new experimental and theoretical bases for the immunotherapy of Guillain-Barre syndrome (GBS). METHODS: CD4+CD25+ Tregs were sorted from the spleens of rats using immunomagnetic bead separation techniques combined with flow cytometry...

Both probiotics and pathogens in the human gut express pathogen-associated molecular patterns (PAMPs) and die with the release of endotoxin and bacterial DNA, which can stimulate our immune system and cause immune reaction. However, it's interesting and fascinating to address why the normal intestinal flora will not generate immunological rejection like the pathogen does. By investigating the changes in cells and molecules relevant to immune tolerance in mice with ceftriaxone-induced dysbacteriosis, our study discovered that both the Evenness indexes and Shannon Wiener index of intestinal flora showed a decrease in dysbacteriosis mice...

Whether γδ T cells inhibit or enhance the Foxp3 T cell response depends upon their activation status. The critical enhancing effector in the supernatant is adenosine. Activated γδ T cells express adenosine receptors at high levels, which enables them to deprive Foxp3+ T cells of adenosine, and to inhibit their expansion. Meanwhile, cell-free supernatants of γδ T cell cultures enhance Foxp3 T cell expansion. Thus, inhibition and enhancement by γδ T cells of Foxp3 T cell response are a reflection of the balance between adenosine production and absorption by γδ T cells...

CD8+ Foxp3+ T cells (Tregs) are a potent regulatory population whose functional and ontological similarities to CD4+ Fox3+ T cells have not been well delineated. Using an experimental model of graft versus host disease (GVHD), we observed that CD8+ Tregs were significantly less potent than CD4+ Tregs for the suppression of GVHD. To define the mechanistic basis for this observation, we examined the T cell repertoire and the transcriptional profile of in vivo-derived CD4+ and CD8+ Tregs that emerged early during this disease...

CD8+ T-regulatory cells are progressively emerging as crucial components of immune system. The previous report suggests the presence of FOXP3-positive CD8+ Treg cells, similar to CD4+ Tregs, in cancer patients which produce high levels of IL10 and TGFβ for its immunosuppressive activities. At an early stage of tumor development, we have identified a subset of FOXP3-negative CD8+ CD25+ KIR+ CD127- a Treg-like subset which is essentially IFNγ-positive. However, this early induced CD8+ CD25+ CD127- T cell subset certainly distinct from the IFNγ+ CD8+ T-effecter cells...
