Abstract Background The liver sinusoidal endothelial cells LSEC and Kupffer cells constitute the most powerful scavenger system in the body. Various waste macromolecules continuously released from tissues in large quantities as a consequence of normal catabolic processes are cleared by the LSEC. In spite of the fact that pig livers are used in a wide range of experimental settings the scavenger properties of pig LSEC has not been investigated until now. Therefore we studied the endocytosis and intracellular transport of ligands for the five categories of endocytic receptors in LSEC. Results Endocytosis of five 125I-labelled molecules collagen a-chains FITC-biotin-hyaluronan mannan formaldehyde-treated serum albumin FSA and aggregated gamma globulin AGG was substantial in cultured LSEC. The endocytosis was mediated via the collagen- hyaluronan- mannose- scavenger- .
