Inability of IFN-γ to increase class I expression on cells containing high levels of tapasin. (a–c) Untreated M553(T240)tpsn cells (dotted lines) and IFN-γ-treated M553(T240)tpsn cells (solid lines) were stained using the mAbs described in Fig. 4. (d) Untreated or IFN-γ-treated M501 cells were stained using the mAb W6/32.
