when distribution of lysosomal cathepsin b and l in liver , which are inhibited strongly by leupeptin , was examined immunohistochemically , cathepsin l is found only in hepatocytes , but cathepsin b is localized in sinusoidal cells rather than in hepatocytes , suggesting that cathepsin l plays a most important role in intralysosomal proteolysis in hepatocytes .
