Mammalian liver contains an endocytic, recycling receptor that mediates the clearance of hyaluronan (HA) and chondroitin sulfate from the circulation. McCourt et al. [J. Biol. Chem. 269 (1994) 30081] previously reported that this endocytic liver HA receptor was ICAM-1. In contrast, we purified this HA receptor for endocytosis (HARE) from rat liver sinusoidal endothelial cells (LECs) and obtained two novel large proteins [Zhou et al., J. Biol. Chem. 274 (1999) 33831]. The goal of the present study was to clarify this inconsistency and determine whether CD44, which is also an HA receptor, or ICAM-1 (CD54) is identical to, or is part of, HARE. Although isolated liver LECs contain HARE, CD44, and ICAM-1, confocal fluorescence microscopy showed that the two latter proteins have cellular distributions that are distinct from and essentially nonoverlapping with HARE. HA accumulation by cultured LECs was inhibited >98% by an antibody against HARE and unaffected by antibodies to ICAM-1 or CD44, indicating that virtually all specific HA uptake is mediated by HARE and not by ICAM-1 or CD44. Finally, no reactivity was observed against purified HARE in an ELISA-based assay using CD44 or ICAM-1 antibodies. The results confirm that the mammalian endocytic HA receptor is HARE and is not ICAM-1 or CD44.
