Leptin is a hormone mainly produced by white adipose cells, and regulates body fat and food intake by acting on hypothalamus. Leptin receptor is expressed not only in the hypothalamus but in a variety of peripheral tissues, suggesting that leptin has pleiotropic functions. In this study, we investigated the effect of leptin on the progression of peritoneal fibrosis induced by intraperitoneal in...
Long-term peritoneal dialysis (PD) leads to histological changes in the peritoneal membrane. Angiogenesis and inflammation caused by glucose degradation products (GDPs) play crucial roles in peritoneal fibrosis. One such GDP is methylglyoxal (MGO), which enhances the formation of advanced glycation end products (AGEs). AGEs bind to their receptor (RAGE) and activate nuclear factor-κB (NF-κB), w...
Recent studies have reported increases of methylglyoxal (MGO) in peritoneal dialysis patients, and that MGO-mediated inflammation plays an important role in the development of peritoneal fibrosis through production of transforming growth factor-β1 (TGF-β1). Linagliptin, a dipeptidyl peptidase-4 inhibitor, exerts anti-inflammatory effects independent of blood glucose levels. In this study, we ex...
Neutrophils isolated from the blood were compared to those from inflammatory exudates in the peritoneal cavity of guinea pigs. Inflammatory neutrophils were shown to have 10-fold more glycogen than blood neutrophils. This was also reflected in the morphology of these cells. The large accumulations of glycogen in inflammatory neutrophils exists in ordered arrays of beta-granules. Other morpholog...
Delayed-type cutaneous reactivity to 2,4-dinitrochlorobenzene and 2,4-dinitrofluorobenzene in guinea pigs was transferred passively by fluids in which leukocytes from sensitive animals were incubated. Cells from peritoneal exudates, lymph nodes, and alveolar washings were employed. The cell-free transfer material was dialyzable, of small molecular size, and stable to 56 C for 30 min and -65 C f...
Normal rat spleens contain suppressor cells which can inhibit proliferative and cytotoxic responses of lymphocytes to alloantigens ijz vitro. The suppressor cells are adherent, phagocytic, resistant to treatment with ATS and C, radioresistant, resistant to treatment with mitomycin C, apparently absent from the thymus, and found in very high concentrations in peritoneal exudates. These character...
Background: The objective of this study was to investigate the relationship between glucose-6-phosphate dehydrogenase inhibition in macrophages treated with 6-Aminonicotinamide, the amount of nitric oxide (NO) production and the resistance of infected macrophages against Leishmania major infection. Methods: Peritoneal macrophages of BALB/c mice were isolated and treated with different concentr...
The molecular mechanisms underlying the peritoneal dissemination of gastric cancer remain unclear. Using in vivo metastatic models, this study attempted to clarify the role of hypoxia inducible factor (HIF)-1α in the development of peritoneal dissemination of gastric cancer. HIF-1α knockdown (KD) cells were established in the scirrhous gastric cancer cell line 58As9. Using KD and control (SC) c...
Background: Endometriosis is a chronic disorder characterized by the presence of endometrial tissue outside the uterus. Endometrial cells from retrograde menstruation implant on peritoneal surfaces and elicit an inflammatory response, associated with angiogenesis, fibrosis, neuronal infiltration, and anatomical distortion. Affecting an estimated 176 million women worldwide, the condition is sti...
Peritonitis and the rare sequela of encapsulating peritoneal sclerosis (EPS) are serious problems in patients on peritoneal dialysis therapy. Chronic and persistent peritoneal injuries may be a risk factor of EPS. We previously reported that a chronic, proliferative peritonitis developed when zymosan was administered intraperitoneally following scraping injury of rat peritoneum (Mizuno M, Ito Y...
