The voltage-gated potassium channel Kv1.3 has been recently identified as a molecular target that allows the selective pharmacological suppression of effector memory T cells (T(EM)) without affecting the function of naïve T cells (T(N)) and central memory T cells (T(CM)). We found that Kv1.3 was expressed on glomeruli and some tubules in rats with(More)
Fasudil, a Rho-kinase inhibitor, may improve insulin signaling. However, its long-term effect on metabolic abnormalities and its preventive effect on diabetic nephropathy are still unknown. We assessed these effects of fasudil in insulin-resistant diabetic rats, comparing them with those of an angiotensin II receptor blocker, olmesartan. Male Otsuka(More)
The mechanisms of hypertensive nephrosclerosis are not fully understood. In experimental models of the disease, inflammatory reactions such as macrophage infiltration play an important role. In human hypertensive nephrosclerosis, however, there have been few studies examining the role of inflammation histologically. We investigated whether the number of(More)
BACKGROUND Corticosteroids are often used for the treatment of glomerular diseases. We examined whether bisphosphonate or vitamin D3 has beneficial effects on bone mineral density (BMD) in patients with glomerular diseases being treated with high-dose corticosteroids, including pulse therapy. METHODS Thirty-eight patients (19 men and 19 women, aged 42 +/-(More)
AIM To examine the additive protective effects of the peroxisome proliferator-activated receptor-gamma agonist pioglitazone (Pio) and the angiotensin II receptor blocker candesartan (Cand) in a murine model of renal fibrosis: mice with unilateral ureteral obstruction (UUO). METHODS Mice were randomly assigned into four groups that after UUO received i.p.(More)
AIM Renal interstitial fibrosis is the final common pathway determining long-term prognosis of chronic kidney diseases, but its repair process is scarcely understood. Because recent reports indicate that M2 macrophages play important roles in the repair of various tissues, special attention was paid to the phenotypes of infiltrating macrophages in the(More)
Interaction between epithelial cells and mesenchymal cells is essential in normal organ morphogenesis and in tissue repair after injury. Epimorphin, a mesenchymal protein that regulates epithelial morphogenesis through epithelial-mesenchymal interactions, has recently attracted attention as an important modulator of tissue repair. In this study we analyzed(More)
BACKGROUND We previously reported that fractalkine was upregulated in streptozotocin-induced diabetic kidneys. Fractalkine in diabetic kidneys was detected on glomerular capillaries and the mesangium. This upregulation was suppressed by treatment with angiotensin-converting enzyme inhibitor (ACE-I) or aminoiguanidine. We examined what factors induce(More)
BACKGROUND Long-term peritoneal dialysis (PD) causes morphologic and functional changes in the peritoneum that hamper the continuation of PD therapy. Because macrophages play important roles in the development of peritoneal fibrosis and liposome-encapsulated clodronate (LC) induces macrophage apoptosis, we examined the effect of LC on chlorhexidine(More)
A 16-year-old male adolescent who had fallen and scratched his knee developed cold-like symptoms. Gross hematuria, oliguria, and peripheral edema appeared about 2 weeks after his fall. Tests showed hypocomplementemia, increased antistreptolysin O titers, and severe kidney failure with hematuria/proteinuria. Kidney biopsy showed endocapillary proliferative(More)
