Background：CD11a is a 180 kD glycoprotein, also known as aL integrin, LFA-1 a, Ly-15, or Ly-21. It is a member of the integrin family, primarily expressed on lymphocytes, monocytes/macrophages, and granulocytes. In association with CD18, the CD11a/CD18 complex forms LFA-1. CD11a plays an important role in intercellular adhesion and costimulation by binding its ligands, ICAM-1 （CD54）, ICAM-2 （CD102）, and ICAM-3 （CD50）.
