title: [The effect of temperature and Ca2+ on the interaction of high-density lipoproteins with epithelial cells in the human small intestine].
abstract: The effect of temperature and Ca2+ ions on the interaction of high-density lipoprotein (HDL3) with human enterocytes was studied. It was shown that Kd measured at 4 degrees C is similar to that at 37 degrees C. Maximal number of binding sites at 37 degrees C is 15-fold times higher than that at 4 degrees C. EDTA (10 mM) and CaCl2 (0.5-5 mM) did not affect binding and uptake of HDL3 by human enterocytes. The obtained results indicate that HDL3-binding with these cells depends on temperature and does not depend on Ca2+ ions.
