Ischemia-reperfusion (I/R) injury impairs microcirculation. This review covers methods to assess microvascular barrier function and I/R-induced endothelial injury in various experimental models.

Area of Science:

  • Physiology
  • Pathology
  • Biomedical Engineering

Background:

  • Ischemia-reperfusion (I/R) injury significantly impacts microcirculation, leading to severe morbidity and mortality.
  • Understanding microvascular dysfunction is crucial for mitigating I/R injury outcomes.

Purpose of the Study:

  • To provide an overview of methods for evaluating microvascular barrier properties.
  • To discuss the application of these methods in studying I/R injury.
  • To survey experimental models used in I/R research.

Main Methods:

  • Measurement of fluid and macromolecule flux across the microvascular barrier.
  • Assessment of microvascular wall permeability parameters.
  • Utilization of diverse experimental models: whole animal, isolated organ, perfused microvessels, and cultured endothelial cells.

Main Results:

  • Detailed discussion of techniques for quantifying microvascular barrier function.
  • Examples of I/R-induced endothelial injury across different experimental systems.
  • Comparative analysis of the strengths and weaknesses of various methodologies.

Conclusions:

  • Effective evaluation of microvascular barrier properties is essential for understanding I/R injury.
  • Diverse experimental models offer complementary insights into I/R-induced endothelial dysfunction.
  • Methodological selection should consider specific research questions and limitations.
