Area of Science:

  • Physiology
  • Cardiovascular Research
  • Microcirculation Studies

Background:

  • Leukocyte-endothelium interactions are critical in cardiovascular inflammatory diseases.
  • Endothelial nitric oxide (NO) plays a vital role in regulating vascular function.

Purpose of the Study:

  • To describe a novel method for simultaneous in vivo measurement of leukocyte-endothelium interactions and NO levels.
  • To enable the study of NO's role in inflammatory states of the cardiovascular system.
  • To investigate the impact of NO-replenishing therapy on leukocyte adhesion.

Main Methods:

  • Combines intravital microscopy for monitoring leukocyte-endothelial cell interactions in vivo.
