Airway inflammation can be assessed by tracking plasma exudates on the mucosal surface. This method offers a detailed view of inflammation intensity and its progression over time.

Area of Science:

  • Pulmonary Medicine
  • Immunology
  • Pathology

Background:

  • Airways inflammation is traditionally defined by inflammatory cells and products.
  • A comprehensive assessment requires evaluating the extent of tissue involvement.
  • Plasma exudation is a key inflammatory response in airway tissue.

Purpose of the Study:

  • To propose plasma tracers on the mucosal surface as a method for assessing airway inflammation.
  • To correlate plasma exudates with the degree and time-course of airway inflammation.

Main Methods:

  • Investigating plasma exudation from subepithelial microvessels as a response to mucosal provocation.
  • Analyzing the reversible and non-injurious nature of plasma exudate in creating intercellular pathways.
  • Examining the integrity of the epithelial lining as a barrier during plasma exudation.

  • Correlating plasma exudates found on the mucosal surface with those in the tissue.

    • Main Results:

    • Plasma exudation is a specific defense/inflammatory response originating from subepithelial microvessels.
    • Extravasated plasma reversibly creates intercellular pathways without compromising epithelial barrier function.
    • A strong correlation exists between plasma exudates on the mucosal surface and within the tissue.

    Conclusions:

    • Plasma tracers on the mucosal surface can effectively identify ongoing airway inflammation.
    • This approach allows for detailed assessment of inflammation intensity and its time-course.
    • Measuring plasma exudates offers a novel method for evaluating airway inflammatory conditions.
