Insights

This study reviews key in vivo models for inducing acute kidney injury (AKI) in research. These models, including ischemia-reperfusion, obstruction, and toxic injury, are crucial for understanding kidney disease.

Area of Science:

  • Nephrology
  • Pathology
  • Experimental Medicine

Background:

  • The kidney's unique physiology, including its vasculature and tubular function, makes it a key organ for studying cell death and injury.
  • Clinically relevant conditions like ischemia-reperfusion injury, kidney fibrosis, and toxic insults are frequently modeled in the kidney.
  • Existing models allow for the investigation of various mechanisms leading to acute kidney injury (AKI).

Purpose of the Study:

  • To introduce and critically review established in vivo models for inducing acute kidney injury (AKI).
  • To provide insights into the protocols used for effectively inducing these models in research settings.
  • To highlight the clinical relevance of these models for studying kidney diseases.

Main Methods:

  • Review of established protocols for inducing kidney injury models.
  • Focus on ischemia-reperfusion injury due to the kidney's specific vasculature.
  • Discussion of unilateral ureteric obstruction for modeling fibrosis.
  • Examination of cisplatin-induced nephrotoxicity and rhabdomyolysis-induced AKI models.

Main Results:

  • The kidney's anatomical and functional characteristics facilitate the study of diverse injury types.
  • Specific models effectively replicate conditions such as ischemia-reperfusion, fibrosis, and toxic AKI.
  • The reviewed protocols provide a foundation for reproducible research into AKI pathogenesis.

Conclusions:

  • The presented in vivo models are essential tools for advancing the understanding of acute kidney injury (AKI).
  • These models offer valuable platforms for investigating therapeutic strategies against kidney damage.
  • Further research utilizing these established protocols will aid in developing treatments for kidney diseases.

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

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...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
