Figure 4From: Identification of proteases employed by dendritic cells in the processing of protein purified derivative (PPD)Pepstatin A Inhibits selectively the cathepsins D/E. XS52 DC were pretreated for 60 min with each of protease inhibitors or vehicles. After extensive washing, the cells were extracted and subsequently examined for protease activities. Data shown are % inhibition compared with untreated control cells.Back to article page
