Naive T Cells Are Isolated and Left Untreated or Treated

question 35

Multiple Choice

Naive T cells are isolated and left untreated or treated with 'compound X' for 1 hour. Following this, the T cells are incubated with a range of concentrations of a soluble form of ICAM-1 that has been conjugated to a fluorescent dye (soluble-ICAM-1-FITC) . Fifteen minutes later, the cells are washed, and the relative amount of fluorescence bound to the cells is measured. The results of this assay are shown in Figure Q6) . Figure Q6) The most likely identity of compound X is:

• A) The adhesion molecule, LFA-1
• B) The adhesion molecule, L-selectin
• C) The sulfated carbohydrate structure, sulfated sialyl-Lewis^X
• D) The chemokine ligand for CCR7
• E) The immunoglobulin superfamily member, CD2
