BACKGROUND Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common hereditary kidney diseases that frequently result in renal failure. In this cross-sectional observational cohort study, we evaluated urinary angiotensinogen (AGT) as a potential biomarker to assess renal function in ADPKD. METHODS Urinary AGT was measured in 233(More)
OBJECTIVE To examine the effects of intravesical cyclooxygenase-2 (COX-2) inhibitors on the expression of inducible nitric oxide synthase (iNOS) and nerve growth factor (NGF) in cyclophosphamide (CYP)-induced overactive bladder (OAB). MATERIALS AND METHODS In all, 40 Sprague-Dawley rats were divided into control, OAB, and COX-2 inhibitor-treated groups.(More)
BACKGROUND The role of hyperuricemia in disease progression of autosomal dominant polycystic kidney disease (ADPKD) has not been defined well. We investigated the association of serum uric acid (sUA) with renal function and the effect of hypouricemic treatment on the rate of renal function decline. METHODS This is a single-center, retrospective,(More)
Extracellular adenosine triphosphate (ATP) binds to purinergic receptors and, as a danger molecule, promotes inflammatory responses. Here we tested whether periodate-oxidized ATP (oATP), a P2X7 receptor (P2X7R) antagonist can attenuate renal ischemia-reperfusion injury and clarify the related cellular mechanisms. Treatment with oATP prior to(More)
BACKGROUND Macrophages play important roles in xenograft rejection. Here, we investigated whether overexpression of human CD200 or CD47 in porcine endothelial cells (PEC) can suppress macrophages activation in xenogeneic immune responses. METHODS PECs and human macrophages were incubated together, harvested and analyzed for in vitro macrophage phagocytic(More)

The pathogenic role of T cells in hypertension has been documented well in recent animal studies. However, the existence of T-cell–driven inflammation in human hypertension has not been confirmed. Therefore, we undertook immunologic characterization of T cells from patients with hypertension and measured circulating levels of C-X-C chemokine receptor type 3(More)
Adoptive transfer of regulatory T cells (Tregs) can delay disease progression and reduce mortality in lupus-prone mice. Here, we tested whether complex (IL-2C) consisting of IL-2 and anti-IL-2 monoclonal antibody (JES6-1) ameliorates lupus nephritis by expanding Tregs as an alternative to problematic Treg infusion therapy. IL-2C treatment of NZB/W F1 mice(More)
BACKGROUND Granulocyte colony-stimulating factor (G-CSF) can induce regulatory T cells (Tregs) as well as myeloid-derived suppressor cells (MDSCs). Despite the immune modulatory effects of G-CSF, results of G-CSF treatment in systemic lupus erythematosus are still controversial. We therefore investigated whether G-CSF can ameliorate lupus nephritis and(More)
