Abstract

Apoptosing cells are actively phagocytosed in parenchymal tissues, thus preventing the inflammatory reaction which could derive from their slow uncontrolled degradation. The molecular mechanisms by which an apoptotic cell is recognized and taken up are largely unknown. We propose that the recognition of apoptotic hepatocytes is mediated by the sugar recognition systems of the liver, particularly the asialoglycoprotein receptor (ASGP-R). The results presented here demonstrate the participation of ASGP-R in the removal of apoptotic parenchymal cells, and indicate a new perspective for the understanding of its physiological role.
