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
