Expression of bcl-2 (A), LFA-1 (B), and ICAM-1 (C). LMP expression induces bcl-2, LFA-1, and ICAM-1 in BJA-B cells but not in CEM cells. The expression of these proteins in different clones of LMP-expressing cells was determined by Western blotting performed on 40 μg of whole-cell lysates. The lanes represent the cell clones indicated in the legend to Fig. 3. Arrows from top to bottom indicate bcl-2, LFA-1, and ICAM-1, respectively.
