Fibrocytes are a distinct population of bloodborne cells that share markers of leukocytes as well as mesenchymal cells. We hypothesized that CCR7-positive fibrocytes migrate into the kidney in response to secondary lymphoid tissue chemokine (SLC/CCL21) and contribute to renal fibrosis. To investigate this hypothesis, renal fibrosis was induced by unilateral(More)
Monocyte chemoattractant protein (MCP)-1, also termed monocyte chemotactic and activating factor (MCAF)/CCL2, plays an important role in progressive organ fibrosis. It was hypothesized that MCP-1, through its cognate receptor, CCR2, regulates the pathogenesis and is therapeutically of importance for renal fibrosis. To achieve this goal, the therapeutic(More)
BACKGROUND A considerable diversity in prognosis is seen with lupus glomerulonephritis (LGN). Hence, the clinical usefulness of a recent International Society of Nephrology/Renal Pathology Society (ISN/RPS) 2003 classification to judge the long-term outcome of human LGN has been investigated. METHODS We studied retrospectively 60 subjects with LGN (7(More)
Fibrocytes are supposed to be a circulating connective tissue cell progenitor, which consists of a novel population of peripheral blood cells. This distinct population of blood-borne cells shares markers of leukocytes as well as mesenchymal cells. Accumulating evidence indicates that fibrosis is characteristic of progressive chronic kidney diseases of any(More)
INTRODUCTION Immunoglobulin G4 (IgG4)-related aortitis/periaortitis and periarteritis are vascular manifestations of IgG4-related disease. In this disease, the affected aneurysmal lesion has been suspected to be at risk of rupture. In this study, we aimed to clarify the clinical course after corticosteroid therapy in IgG4-related aortitis/periaortitis and(More)
BACKGROUND In Japan, systematic evaluation of the histologic parameters of anti-neutrophil cytoplasmic autoantibodies (ANCA)-related vasculitis has been performed according to the Japanese classification by Shigematsu et al. However, this classification is quite different from that of the European Vasculitis Study Group (EUVAS) classification. Therefore, a(More)
Ischemia-reperfusion injury is a main cause of acute kidney injury. Tubular necrosis and interstitial inflammatory cell infiltration are characteristic pathologic changes of acute kidney injury. The main necrotic area should be repaired with new tubular epithelial cells after the injury. On the other hand, some parts of the injured kidney progress to(More)
BACKGROUND A new histopathological classification of anti-neutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis was recently proposed. We evaluated the predictive value of this classification for renal outcome in Japanese patients. METHODS We enrolled 122 patients with ANCA-associated glomerulonephritis diagnosed at several institutions in(More)
OBJECTIVE Ischemia-reperfusion injury is known to cause organ failure, but the mechanisms of pathogenesis remain unclear. Inflammation is a factor in tissue destruction in ischemia reperfusion injury, and interleukin (IL)-1 is a key promoter of inflammation. DESIGN Prospective, randomized, and controlled study. SETTING University laboratory. SUBJECTS(More)
OBJECTIVE In this study, locally advanced bladder cancer was treated by radiation combined with cisplatin therapy and a retrospective analysis was conducted to predict the clinical response to chemoradiotherapy (CRT) based on the immunohistochemistry of apoptosis-related proteins. METHODS Sixty-two patients (median age, 68 years; range, 45-89 years) with(More)
