Recent advances in cell and molecular biology have elucidated key structures in leukocyte-endothelial interactions. This research refines our understanding of leukocyte emigration and its role in inflammatory and immune responses.

Area of Science:

  • Immunology
  • Cell Biology
  • Molecular Biology

Background:

  • Significant progress in understanding leukocyte-endothelial interactions since the last review.
  • Advancements driven by cell and molecular biology techniques.

Purpose of the Study:

  • To review and synthesize current knowledge on leukocyte adherence and migration across endothelium.
  • To outline an operative paradigm for the molecular basis of leukocyte emigration.

Main Methods:

  • Intravital microscopy and histology.
  • Functional and immunologic characterization of adhesion molecules.
  • Development of genetically deficient animal models and early human trials of anti-adhesion therapy.

Main Results:

Related Experiment Videos

  • Molecular cloning and functional definition of leukocyte integrins, endothelial Ig superfamily members, and selectins.
  • Established a paradigm for the molecular basis of leukocyte emigration.
  • Highlighted the need for in vitro and in vivo studies on adhesion molecule regulation.

Conclusions:

  • The current paradigm of leukocyte emigration is well-supported but requires refinement.
  • Further research is needed to dissect individual adhesion molecule contributions in inflammatory models.
  • New adhesion structures are anticipated, promising insights into inflammatory diseases and novel therapies.
