The effect of vitamin E-bonded polysulfone membrane dialyzer on a new oxidative lipid marker.

The use of vitamin E-bonded cellulose membrane dialyzers has been reported to cause a decrease in oxidative lipid marker levels (Nakai et al., Ther Apher Dial 14:505-540, 1; Nakai et al., J Jpn Soc Dial Ther 45:1-47, 2; Mashiba et al.

A mixture of Salacia oblonga extract and IP-PA1 reduces fasting plasma glucose (FPG) and low-density lipoprotein (LDL) cholesterol levels.

At present, lifestyle-related diseases are one of the most critical health issues worldwide. It has been reported that lipopolysaccharide derived from a Gram-negative bacteria (IP-PA1) symbiotic with wheat exhibited several advantageous biological effects, such as the reduction of plasma glucose levels in NOD mice and low-density lipoprotein (LDL) levels in WHHL rabbits. In this study, the beneficial effects on plasma glucose and lipids of a tea (SI tea) consisting of IP-PA1 and Salacia (which contains an inhibitor of α-glucosidase) were investigated in the KK-Ay/TaJcl type 2 diabetic model mice and in human subjects with premetabolic syndrome in a double-blind, randomized study.

Intestinal macrophages involved in the homeostasis of the intestine have the potential for responding to LPS.

Recently, there has been interest in the tertiary functions of food, those that maintain human health. Moreover, lipopolysaccharides (LPS), which are components of Gram-negative bacteria, have been found to be highly effective in activating innate immunity and have been rediscovered as new functional food materials. In this review, we discuss the significance of LPS as a food component with reference to these tertiary functions based on recent findings.

Mechanism for maintaining homeostasis in the immune system of the intestine.

Every organism possesses a mechanism for maintaining homeostasis. We have focused on the immune system as a system that helps maintain homeostasis of the body, and particularly on the intestine as the largest organ of immunity in the body. We have also focused our research on the mechanism that responds to foreign substances in the intestine, especially the toll-like receptors (TLR).

Intracellular localization of CD14 protein in intestinal macrophages.

Background: Our research is focused on intestinal macrophages, which are believed to contribute to the maintenance of intestinal homeostasis. In addition, intestinal macrophages are unique in that there is an impairment of expression of tumor necrosis factor (TNF) from lipopolysaccharide (LPS). This characteristic can be attributed to the lack or poor level of expression of toll-like receptor 4 (TLR4) or CD14 on the membrane of intestinal macrophages.

Utility and safety of LPS-based fermented flour extract as a macrophage activator.

The immune system is part of the homeostasis system. Our research is focused on ways to maintain health, with an emphasis on the role of macrophages. We have hypothesized that tissue macrophages form a systemic network which we believe contributes to the homeostasis system, and have named it the 'macrophage network.

Development and potential use of a monoclonal antibody to the lipopolysaccharide of Pantoea agglomerans (IP-PA1).

Background: The lipopolysaccharide of Pantoea agglomerans (IP-PA ) has been shown to be effective and safe in the prevention of various diseases, such as bacterial or viral infection, lifestyle-related diseases, when administered transdermally or orally. To clarify the mechanisms of the preventive or therapeutic effect induced by IP-PA1, we tried to establish a monoclonal antibody to detect IP-PA1. The enzyme-linked immunosorbent assay (ELISA) was used to measure the amount of IP-PA1.

Treatments for the activating macrophages that reduces surgical stress and postoperative mortalities from bacterial infections and tumor metastases.

Background: Some of the mortalities caused by infectious diseases and/or distant metastases following surgery are thought to be due to immunological suppression. For this reason, techniques that reduce immunological suppression following surgery may reduce mortalities and/or incidences of micrometastases in distant organs.

Materials And Methods: Mice were anesthetized and their peritoneal cavities were opened for 30 min.

Unique molecular characteristics of the environmental responses of mucosal macrophages.

Macrophages are thought to be the cells that initially respond to environmental information and transmit this information to other immune cells. We hypothesize that there is a "network system" consisting of various tissue macrophages; the macrophages respond to stimulation and transmit secondary information to neighboring cells, which is important for the maintenance of homeostasis. Macrophages exist in all animal organs as tissue macrophages, and their cellular characteristics may change as an adaption to tissue-specific environments.

Cloning and characterization of a TNF-like protein of Plecoglossus altivelis (ayu fish).

Ayu TNF cDNA contains an open reading frame of 708bp encoding 235 amino acids. Poly adeniration (A) signal and eight AU-rich sequences were present in 858bp 3' UTR. Southern blot analysis indicated that ayu TNF is single-copy gene.
