Insights

Targeting TWEAK (TNF-like weak inducer of apoptosis) and its receptor Fn14 shows promise for treating acute kidney injury (AKI) and chronic kidney disease (CKD). Further research is needed to understand its role in kidney inflammation.

Area of Science:

  • Nephrology
  • Immunology
  • Molecular Biology

Background:

  • Acute kidney injury (AKI) and chronic kidney disease (CKD) incidence is rising globally.
  • Current therapies for AKI are lacking, and CKD treatments only slow progression.
  • TWEAK/Fn14 pathway is implicated in kidney injury, with preclinical and clinical evidence.

Purpose of the Study:

  • To explore the therapeutic potential of targeting the TWEAK/Fn14 pathway in AKI and CKD.
  • To investigate the role of non-canonical Nuclear Factor-kappa B (NF-κB) activation in TWEAK-mediated kidney inflammation.
  • To enhance understanding of TWEAK's contribution to kidney disease pathogenesis.

Main Methods:

  • Review of preclinical data on TWEAK/Fn14 targeting in mouse models of AKI and CKD.
  • Analysis of clinical evidence regarding TWEAK and Fn14 levels in human kidney injury.
  • Examination of the role of non-canonical NF-κB pathway activation in TWEAK-induced inflammatory responses.

Main Results:

  • Preclinical studies indicate TWEAK/Fn14 targeting preserves renal function and reduces injury markers.
  • Clinical data show elevated TWEAK and Fn14 levels in human kidney disease.
  • TWEAK activates non-canonical NF-κB pathways, promoting inflammation in renal tubular cells.

Conclusions:

  • Targeting the TWEAK/Fn14 axis represents a potential therapeutic strategy for AKI and CKD.
  • Understanding non-canonical NF-κB activation is crucial for elucidating TWEAK's role in kidney disease.
  • Further investigation into TWEAK's mechanisms in vivo is warranted for clinical translation.

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Nephrons01:10

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
