We recently identified elements in the C-terminal domain of apolipoprotein
E that are critical for the binding of this protein to the protein core of
biglycan, a proteoglycan of the vascular extracellular matrix. This binding
, ionic in nature, requiring no participation by glycosaminoglycans, sugges
ts that protein-protein interactions may play an important role in the bind
ing of apolipoprotein E to the extracellular matrix. These interactions may
represent a potential mechanism for the anti-atherogenic potential of this
apolipoprotein by preventing further anchoring to the vascular matrix of p
ro-atherogenic factors. (Trends Cardiovasc Med 2001; 11:263-268). (C) 2001,
