Describe in chronological order how T cells migrate across lymph node high endothelial venules (HEVs) from the blood by using these molecules
What will be an ideal response?
Chemokines made by endothelium and bound to its extracellular matrix induce T cells to express LFA-1, an integrin. LFA-1 binds with high affinity to an intercellular adhesion molecule, ICAM-1, expressed on the endothelium. Finally, the T cell squeezes between the endothelium junctions, a process called diapedesis, and hence gains entry into the lymph node.
