Area of Science:

  • Immunology
  • Cell Biology
  • Biochemistry

Background:

  • Chemoattractants and chemokine superfamily members regulate leukocyte trafficking and activation via seven transmembrane (STM) G protein-coupled receptors.
  • These signaling molecules are widely expressed by various cell types, either constitutively or upon stimulation.
  • Decades of research have established the pathophysiological significance of chemoattractants and their receptors.

Purpose of the Study:

  • To elucidate the intricate roles of chemoattractants and their receptors in biological processes.
  • To highlight recent advancements in understanding chemoattractant involvement in health and disease.

Main Methods:

  • Utilized transgenic technology.
  • Employed gene targeting techniques.
