The α7nAChR agonist PNU-282987 ameliorates sepsis-induced acute kidney injury via CD4+CD25+ regulatory T cells in rats.

Bosn J Basic Med Sci 2022 May 10. Epub 2022 May 10.

Department of Surgical Intensive Critical Unit, Beijing Chao-yang Hospital, Capital Medical University, Beijing, China.

The ameliorative effects of α7 nicotinic acetylcholine receptor (α7nAChR) agonists have been demonstrated in acute kidney injury (AKI) caused by multiple stimulations. However, the ameliorative effect of α7nAChR on sepsis-induced acute kidney injury (SAKI) in the cecal ligation and puncture (CLP) model is unclear. Previous studies have demonstrated that α7nAChR is highly expressed on the surface of CD4+CD25+ regulatory T cells (Tregs). Read More

Cureus 2022 Mar 31;14(3):e23681. Epub 2022 Mar 31.

Department of Surgery, Beaumont Health, Farmington Hills, USA.

Fibrin-associated diffuse large B-cell lymphoma (FA-DLBCL) is in and of itself a rare entity and is a subset of the Epstein-Barr virus (EBV)-associated lymphoma. Due to its indolent course, FA-DLBCL is generally an incidental finding on histopathological examinations. We present the first reported case of FA-DLBCL found within a native aortic thrombus during an aorto-biiliac bypass. Read More

TLR2/caspase-5/Panx1 pathway mediates necrosis-induced NLRP3 inflammasome activation in macrophages during acute kidney injury.

Cell Death Discov 2022 Apr 26;8(1):232. Epub 2022 Apr 26.

Clinical Research Center of Kidney Disease, State Key Laboratory of Organ Failure Research, Guangdong Provincial Institute of Nephrology, Guangdong Provincial Key Laboratory of Renal Failure Research, Division of Nephrology, Nanfang Hospital, Southern Medical University, Guangzhou, PR China.

Acute kidney injury (AKI) is characterized by necroinflammation formed by necrotic tubular epithelial cells (TECs) and interstitial inflammation. In necroinflammation, macrophages are key inflammatory cells and can be activated and polarized into proinflammatory macrophages. Membranous Toll-like receptors (TLRs) can cooperate with intracellular NOD-like receptor protein 3 (NLRP3) to recognize danger signals from necrotic TECs and activate proinflammatory macrophages by assembling NLRP3 inflammasome.

Department of Physiology, College of Medicine and Health Sciences, United Arab Emirates University, Al Ain P.O. Box 17666, United Arab Emirates.

Cisplatin (CP) treatment has been long associated with the development of acute kidney injury (AKI) through mechanisms involving inflammation and oxidative stress. α-Bisabolol (BIS), a sesquiterpene alcohol isolated from the essential oil of various plants, including chamomile, has garnered popularity lately due to its antioxidant, anti-inflammatory, and anticancer properties. Therefore, we investigated the nephroprotective effects of BIS in the murine model of CP-induced AKI and the underlying mechanism of action. Read More

Sci Transl Med 2022 Apr 13;14(640):eabk2709. Epub 2022 Apr 13.

Inflammation and Immune Mediated Diseases Laboratory of Anhui Province, the Key Laboratory of Anti-inflammatory of Immune Medicines, Ministry of Education, Anhui Institute of Innovative Drugs, School of Pharmacy, Anhui Medical University, Hefei 230032, China.

The role of -methyladenosine (m6A) modifications in renal diseases is largely unknown. Here, we characterized the role of -adenosine-methyltransferase-like 3 (METTL3), whose expression is elevated in renal tubules in different acute kidney injury (AKI) models as well as in human biopsies and cultured tubular epithelial cells (TECs). silencing alleviated renal inflammation and programmed cell death in TECs in response to stimulation by tumor necrosis factor-α (TNF-α), cisplatin, and lipopolysaccharide (LPS), whereas overexpression had the opposite effects.

The Urinary Level of Injury Biomarkers Is Not Univocally Reflective of the Extent of Toxic Renal Tubular Injury in Rats.

Int J Mol Sci 2022 Mar 23;23(7). Epub 2022 Mar 23.

Institute of Biomedical Research of Salamanca (IBSAL), 37007 Salamanca, Spain.

Nephrotoxicity is a major cause of intrinsic acute kidney injury (AKI). Because renal tissue damage may occur independently of a reduction in glomerular filtration rate and of elevations in plasma creatinine concentration, so-called injury biomarkers have been proposed to form part of diagnostic criteria as reflective of tubular damage independently of renal function status. We studied whether the urinary level of NGAL, KIM-1, GM2AP, t-gelsolin, and REGIIIb informed on the extent of tubular damage in rat models of nephrotoxicity, regardless of the etiology, moment of observation, and underlying pathophysiology.

Stem Cell-Derived Extracellular Vesicles as Potential Therapeutic Approach for Acute Kidney Injury.

Front Immunol 2022 10;13:849891. Epub 2022 Mar 10.

Nephrology and Kidney Transplantation Unit, "Maggiore della Carità" University Hospital, Department of Translational Medicine, Translational Research on Autoimmune and Allergic Disease (CAAD), University of Piemonte Orientale (UPO), Novara, Italy.

Acute kidney injury is a frequent complication of hospitalized patients and significantly increases morbidity and mortality, worsening costs and length of hospital stay. Despite this impact on healthcare system, treatment still remains only supportive (dialysis). Stem cell-derived extracellular vesicles are a promising option as they recapitulate stem cells properties, overcoming safety issues related to risks or rejection or aberrant differentiation.

The Challenges of Diagnosing Nondilated Obstructive Uropathy: A Case Report.

Can J Kidney Health Dis 2022 26;9:20543581221086683. Epub 2022 Mar 26.

Division of Nephrology, Rush University Medical Center, Chicago, IL, USA.

Rationale: Nondilated obstructive uropathy (NDOU) is a rare cause of acute renal failure reported in less than 5% of cases of obstructive uropathy. It is typically associated with intrapelvic malignancies and diseases causing retroperitoneal lymphadenopathy and retroperitoneal fibrosis. As these conditions may prevent radiographic dilation of the collecting system, the diagnosis of NDOU may be missed by usual diagnostic testing. Read More

Am J Physiol Renal Physiol 2022 May 21;322(5):F553-F572. Epub 2022 Mar 21.

Kidney Research Institute, Seoul National University, Seoul, Korea.

Signal transducer and activator of transcription 3 (STAT3) is a pivotal mediator of IL-6-type cytokine signaling. However, the roles of its full-length and truncated isoforms in acute kidney injury (AKI) and its transition to chronic kidney disease (CKD) remain elusive. Herein, the role of STAT3 isoforms in the AKI-to-CKD transition was characterized using an ischemia-reperfusion injury (IRI) mouse model. Read More
