We thank Drs Pinal-Fernandez and Mammen for their constructive comments on our article (1). We also thank them about their remark related to the correlations between muscle levels of ISG15 and muscle involvement. We fully agree that an accurate class

The necrosis of muscle fibres (myonecrosis) plays a central role in the pathogenesis of several muscle conditions, including muscular dystrophies. Therapeutic options addressing the causes of muscular dystrophy pathogenesis are expected to alleviate

Cytotoxicity of many plant and bacterial toxins requires their endocytosis and retrograde transport from endosomes to the endoplasmic reticulum. Using cell fractionation and immunoblotting procedures, we have assessed the fate and action of the plant

The insulin receptor and insulin signaling proteins downstream the receptor reside in different subcellular compartments and undergo redistribution within the cell upon insulin activation. Endocytosis of the insulin-receptor complex, by mediating lig

To assess Pseudomonas exotoxin A (ETA) compartmentalization, processing and cytotoxicity in vivo, we have studied the fate of internalized ETA with the use of the in vivo rodent liver model following toxin administration, cell-free hepatic endosomes,

The molecular adaptor Grb14 binds in vitro to the activated insulin receptor (IR) and inhibits IR signaling. In this study, we have used rat liver subcellular fractionation to analyze in vivo insulin effects on Grb14 compartmentalization and IR phosp

Using the in situ liver model system, we have recently shown that, after cholera toxin binding to hepatic cells, cholera toxin accumulates in a low-density endosomal compartment, and then undergoes endosomal proteolysis by the aspartic acid protease

IGF-I is degraded within the endosomal apparatus as a consequence of receptor-mediated endocytosis. However, the nature of the responsible protease and the position of the cleavage sites in the IGF-I molecule remain undefined. In vitro proteolysis of

The endosomal compartment of hepatic parenchymal cells contains an acidic endopeptidase, endosomal acidic insulinase, which hydrolyzes internalized insulin and generates the major primary end product A(1--21)-B(1--24) insulin resulting from a major c
