Mucosal Vaccine Delivery Using Mucoadhesive Polymer Particulate Systems.

Vaccination has been recently attracted as one of the most successful medical treatments of the prevalence of many infectious diseases. Mucosal vaccination has been interested in many researchers because mucosal immune responses play part in the first line of defense against pathogens. However, mucosal vaccination should find out an efficient antigen delivery system because the antigen should be protected from degradation and clearance, it should be targeted to mucosal sites, and it should stimulate mucosal and systemic immunity.

The durability and effectiveness of sensor-augmented insulin pump therapy in pediatric and young adult patients with type 1 diabetes.

Purpose: Despite the prevalent use of insulin pump therapy worldwide, few studies have been conducted among young patients with type 1 diabetes (T1D) in Korea. We investigated the durability and effectiveness of insulin pump therapy among Korean pediatric and young adult patients with T1D.

Methods: This study included 54 patients with T1D diagnosed at pediatric ages (range, 1.

Characterization of splenic MRC1MHCII and MRC1MHCII cells from the monocyte/macrophage lineage of White Leghorn chickens.

Monocytes/macrophages, which are found in a variety of organs, maintain tissue homeostasis at a steady state and act as the first line of defence during pathogen-induced inflammation in the host. Most monocyte/macrophage lineage studies in chickens have been largely performed using cell lines, while few studies using primary cells have been conducted. In the present study, the phenotypic and functional characteristics of splenic monocyte/macrophage lineage cells during steady state and inflammatory conditions were examined.

Hydrolyzed fumonisin B induces less inflammatory responses than fumonisin B in the co-culture model of porcine intestinal epithelial and immune cells.

Fumonisin B (FB), mainly produced by Fusarium verticillioides and Fusarium proliferatum, can be converted to the less toxic metabolite hydrolyzed FB (HFB) by enzymatic degradation. The application of an FBdegrading enzyme as a feed additive is a strategy to reduce fumonisin exposure of animals. However, the difference between the effect of FB and HFB on porcine intestinal immunity is poorly documented.

Cysteine-X-cysteine motif chemokine ligand 12 and its receptor CXCR4: expression, regulation, and possible function at the maternal-conceptus interface during early pregnancy in pigs.

Cysteine-X-cysteine (CXC) motif chemokine ligand 12 (CXCL12) and its receptor, CXC chemokine receptor type 4 (CXCR4), are involved in regulating the proliferation, migration, and survival of trophoblast cells and the maternal immune response in humans and mice. The present study examined the expression, regulation, and function of CXCL12 and CXCR4 at the maternal-conceptus interface during pregnancy in pigs. The endometrium expressed CXCL12 and CXCR4 mRNAs with the greatest CXCL12 abundance on Day 15 of pregnancy.

Transcription Factor KLF10 Constrains IL-17-Committed Vγ4 γδ T Cells.

γδ T cells, known to be an important source of innate IL-17 in mice, provide critical contributions to host immune responses. Development and function of γδ T cells are directed by networks of diverse transcription factors (TFs). Here, we examine the role of the zinc finger TFs, Kruppel-like factor 10 (KLF10), in the regulation of IL-17-committed CD27 γδ T (γδ-17) cells.

Analysis of cysteine-X-cysteine motif chemokine ligands 9, 10, and 11, their receptor CXCR3, and their possible role on the recruitment of immune cells at the maternal-conceptus interface in pigs.

Chemokines play critical roles in the establishment and maintenance of pregnancy in animals. Cysteine-X-cysteine motif chemokine ligand 9 (CXCL9), CXCL10, and CXCL11 are involved in recruiting immune cells by binding to their shared receptor, CXC receptor 3 (CXCR3), in a variety of tissues. This study examined the expression and regulation of chemokines CXCL9, CXCL10, and CXCL11, their receptor CXCR3, and their role at the maternal-conceptus interface in pigs.

H9N2-specific IgG and CD4+CD25+ T cells in broilers fed a diet supplemented with organic acids.

Organic acids have long been known for their beneficial effects on growth performance in domestic animals. However, their impact on immune responses against viral antigens in chickens is unclear. The present study aimed to investigate immunological parameters in broilers immunized with a H9N2 vaccine and/or fed a diet containing organic acids (citric, formic, and lactic acids).

Effects of ambient temperature and dietary glycerol addition on growth performance, blood parameters and immune cell populations of Korean cattle steers.

Objective: This study was performed to evaluate whether ambient temperature and dietary glycerol addition affect growth performance, and blood metabolic and immunological parameters, in beef cattle.

Methods: Twenty Korean cattle steers (405.1±7.

Effects of road transportation on metabolic and immunological responses in Holstein heifers.

This study examined the effects of road transportation on metabolic and immunological responses in dairy heifers. Twenty Holstein heifers in early pregnancy were divided into non-transported (NT; n = 7) and transported (T; n = 13) groups. Blood was collected before transportation (BT), immediately after transportation for 100 km (T1) and 200 km (T2), and 24 h after transportation (AT).

Barrier protection via Toll-like receptor 2 signaling in porcine intestinal epithelial cells damaged by deoxynivalnol.

Intestinal barrier is the first line of defense inside the body and comprises intercellular tight junction (TJ) proteins that regulate paracellular permeability. Deoxynivalenol (DON), a fungal metabolite often found in the contaminated food of domestic animals, is known to impair intestinal barrier function and may be involved in intestinal inflammation. Unlike in humans and mice, the importance of Toll-like receptor (TLR) 2 expressed in porcine intestinal epithelial cells is largely unclear.

Systemic administration of RANKL overcomes the bottleneck of oral vaccine delivery through microfold cells in ileum.

A successful delivery of antigen through oral route requires to overcome several barriers, such as enzymatic barrier of gastrointestinal tract and epithelial barrier that constitutes of microfold cells (M cells) for antigen uptake. Although each barrier represents a critical step in determining the final efficiency of antigen delivery, the transcytosis of antigen by M cells in the follicle-associated epithelium (FAE) to Peyer's patches appears to be a major bottleneck. Considering the systemic administration of receptor activator of nuclear factor (NF)-ĸB ligand (RANKL) induces differentiation of receptor activator of nuclear factor (NF)-ĸB (RANK)-expressing enterocytes into M cells, here, we illustrated a promising approach of antigen delivery using full length transmembrane RANKL (mRANKL).

A Bacterial Metabolite, Compound K, Induces Programmed Necrosis in MCF-7 Cells via GSK3β.

Ginsenosides, the major active component of ginseng, are traditionally used to treat various diseases, including cancer, inflammation, and obesity. Among these, compound K (CK), an intestinal bacterial metabolite of the ginsenosides Rb1, Rb2, and Rc from Bacteroides JY-6, is reported to inhibit cancer cell growth by inducing cell-cycle arrest or cell death, including apoptosis and necrosis. However, the precise effect of CK on breast cancer cells remains unclear.

Ginsenoside fractions regulate the action of monocytes and their differentiation into dendritic cells.

Background: Panax ginseng (i.e., ginseng) root is extensively used in traditional oriental medicine.

Bacillus subtilis Protects Porcine Intestinal Barrier from Deoxynivalenol via Improved Zonula Occludens-1 Expression.

Intestinal epithelial cells (IECs) forming the barrier for the first-line of protection are interconnected by tight junction (TJ) proteins. TJ alteration results in impaired barrier function, which causes potentially excessive inflammation leading to intestinal disorders. It has been suggested that toll-like receptor (TLR) 2 ligands and some bacteria enhance epithelial barrier function in humans and mice.

Web-based comprehensive information system for self-management of diabetes mellitus.

Background: The aim of this study is to evaluate the effect of a web-based comprehensive information system, consisting of Internet and cellular phone use, on blood glucose control.

Methods: We established eMOD (electronic Management of Diabetes), a web-based ubiquitous information system, for cell phone users along with a website for Internet users to provide diabetes education. We examined whether this information system has the same impact on glycemic control as conventional education for the diabetes patient.
