Area of Science:

  • Immunology
  • Microcirculation Research
  • Vascular Biology

Background:

  • Lymph nodes (LNs) are critical immune organs regulating adaptive immune responses.
  • The microvasculature, including arterioles and high endothelial venules (HEVs), is essential for immune cell trafficking into LNs.
  • Understanding LN microvascular dynamics is key to elucidating immune system function.

Purpose of the Study:

  • To present a novel in vivo imaging method for the inguinal lymph node (LN) microvasculature.
  • To enable detailed study of healthy, viable microvessels over extended periods.
  • To facilitate quantification of microvessel characteristics and immune cell dynamics.

Main Methods:

  • Intravital microscopy of the inguinal lymph node in vivo.
  • Focus on imaging healthy and viable microvasculature over hours.
  • Methods for perfusion with vasoactive drugs and quantification of cellular traffic.

Main Results:

  • Successful in vivo imaging of the inguinal LN microvasculature.
  • Demonstrated ability to maintain imaging of viable vessels.
  • Presented methods for assessing microvascular function and immune cell trafficking.

Conclusions:

  • Intravital microscopy of the inguinal LN provides direct evaluation of microvascular functionality.
  • This technique enables real-time study of the interface between immune cells, LNs, and microcirculation.
  • The method is adaptable for studying other LNs and can be combined with various immunological techniques.
