Although M2 macrophages are known to be indispensible for short-term recovery, they are thought to be main culprit in the development of renal fibrosis following IRI.

Regulatory T cells (Tregs) can suppress immunologic damage in renal ischemia-reperfusion injury (IRI), but the isolation and ex vivo expansion of these cells for clinical application remains challenging. Here, we investigated whether the IL-2/anti-IL-2 complex (IL-2C), a mediator of Treg expansion, can attenuate renal IRI in mice. IL-2C administered before bilateral renal IRI induced Treg expansion in both spleen and kidney, improved renal function, and attenuated histologic renal injury and apo

Acute kidney injury (AKI) increases the risk of end stage renal disease among the elderly, but the precise underlying mechanism is unknown. We investigated the effects of aging on AKI-to-chronic kidney disease (CKD) transition, focusing on renal inflammation. Aged and young C57BL/6 mice were subjected to bilateral ischemia-reperfusion injury (IRI). Baseline proinflammatory cytokine levels of kidneys were elevated in aged mice. After IRI, aged mice also showed persistent M1 dominant inflammation,

Cisplatin, a major anti-neoplastic drug, is known to be nephrotoxic and inflammation-inducing. A peroxisome proliferator-activated receptor gamma agonist, regulating lipid metabolism, has known to have anti-inflammatory effect, but the protection mechanisms in various kidney injuries are not fully understood. The purpose of this study was to examine the reno-protective effect of rosiglitazone on cisplatin nephrotoxicity in mice focusing on inflammation and apoptosis. Male BALB/c mice were pretre

Large microbial communities reside in the gut as an endogenous organ and interact with the host physiology through symbiotic relationships, affecting health. Recent advances in high-throughput sequencing techniques have made it possible to better understand these complex microbial communities and their effects on hosts. Animal and clinical studies have provided considerable evidence to show that the microbiota plays an important role in chronic kidney disease, acute kidney injury, nephrolithiasi

Introduction This study investigated the role of renal-intestinal crosstalk in the transition from acute kidney injury (AKI) to chronic kidney disease (CKD) in elderly individuals. Methods Using young and aged mice, we induced bilateral ischemia-reperfusion injury (IRI) and compared intestinal and kidney inflammation over 28 days. To determine the role of the microbiome in gut–kidney crosstalk, we analyzed the microbiome of fecal samples of the young vs. aged mice and examined the effects of pro

Although macrophages are important players in the injury/repair processes in animal models of acute kidney injury (AKI), their roles in human AKI remains uncertain owing to a paucity of human biopsy studies. We investigated the role of macrophages in 72 cases of biopsy-proven acute tubular necrosis (ATN) and six cases of healthy kidney. Macrophages were identified by CD68 and CD163 immunohistochemistry and analyzed for their effect on renal outcomes. CD163+ M2 macrophages outnumbered CD68+ cells

Expansion of the proinflammatory CD14(+)CD16(+) monocyte subset partially accounts for chronic inflammation, malnutrition, and atherosclerosis in CKD.

AIM: Chronic antibody-mediated rejection (CAMR) in renal transplant patients has poor allograft outcomes. However, treatment strategy has not been established yet. Herein, we present short-term outcomes of combination therapy for CAMR. METHODS: We identified nine patients with CAMR or suspicious CAMR who were treated with antihumoral therapy from 2010 to 2011 and analyzed their medical records retrospectively. RESULTS: Five patients had CAMR, and four patients had suspicious CAMR. Severe transpl

Using quenched chiral perturbation theory, we calculate one-loop corrections to the axial charges of the octet baryons in the quenched approximation to quantum chromodynamics. The results are used to compare chiral corrections to the axial charges in full QCD chiral perturbation theory with those in quenched QCD. We find that the quenched chiral perturbation theory result ${c}_{0}^{Q}{+(c}_{l0}^{Q}{+c}_{l2}^{Q}{m}_{\ensuremath{\pi}}^{2})\mathrm{ln}{m}_{\ensuremath{\pi}}^{2}{+c}_{2}^{Q}{m}_{\ensu
