Comparative binding and degradation of lipoprotein(a) and low density lipoprotein by human monocyte-derived macrophages.

Abstract

The binding and degradation of equimolar concentrations of lipoprotein(a) (Lp(a)) and low density lipoprotein (LDL) isolated from the same individual were studied in primary cultures of human monocyte-derived macrophages (HMDM). At 4 degrees C, LDL receptor-mediated binding of both Lp(a) and LDL was of low affinity, being 0.8 and 0.23 microM, respectively… (More)
