Cím:	Specific and scavenger low density lipoprotein receptors involved in the disturbed lipid metabolism of patients with non-insulin-dependent diabetes melitus are independent of obesity / György Paragh, Éva Kovács, Márton Szabolcs, Jenő Szabó, Zoltán Balogh, Péter Kovács, Gabriella Fóris
Dátum:	1998
Megjegyzések:	Comparative studies were performed on monocyte-derived macrophages (MDMs), prepared by a 72-hour incubation of blood monocytes obtained from patients with non-insulin-dependent diabetes mellitus (NIDDM) and age-matched obese and non-obese controls. The MDMs, after a 72-hour culturing, expressed both specific and scavenger low-density lipoprotein (LDL) receptors on their surfaces. To study the binding capacity of both receptor types, [125I]LDL and [125I] acetylated LDL (acLDL) were applied to cells and the labeled ligands were then monitored to estimate the rate of intracellular degradations. The LDL-induced inhibition of endogenous cholesterol synthesis and the acLDL-triggered apolipoprotein (apo) E secretion were also studied, as the biological marker of receptor activation. The results indicate that the binding capacities of both specific and scavenger LDL receptors were not reduced in MDMs of diabetic patients. However, the intracellular degradation after LDL incorporation was decreased. The LDL-induced inhibition of cholesterol synthesis and the acLDL-transmitted apo E secretion were also found to be decreased in the MDMs of patients with NIDDM as compared with the obese and non-obese control groups. The NIDDM-induced impaired signal transduction of both specific and scavenger LDL receptors suggests an unclarified functional alteration of both receptor structures
