Human chylomicron apolipoprotein metabolism

Biochemical and Biophysical Research Communications, 1978
Abstract Chylomicron apolipoprotein metabolism was studied utilizing chylomicrons isolated from the pleural fluid of a patient with a recurrent chylous pleural effusion. Chylomicrons contained apolipoproteins A-I, A-II, B, C-I, C-II, C-III, D, E, and albumin.

Metabolism of chylomicron phosphatidylethanolamine in the rat

Biochimica et Biophysica Acta (BBA) - Lipids and Lipid Metabolism, 1984
10 min after intravenous injection of 32P-labelled chylomicrons 69% of the [32P]phosphatidylethanolamine, but only 34% of the [32P]phosphatidylcholine, was cleared from plasma. Over this time period the plasma phosphatidylethanolamine concentration that was increased after the chylomicron injection returned to normal, indicating that the rapid ...

IDL, VLDL, chylomicrons and atherosclerosis

European Journal of Epidemiology, 1992
In humans with the lipoprotein lipase deficiency disorder large amounts of chylomicrons and large very low-density lipoprotein (VLDL) accumulate in plasma. In spite of this, atherosclerosis does not seem to develop at an accelerated rate, suggesting that these lipoproteins do not promote atherogenesis.

Metabolism of chylomicrons in patients with congenital lipoatrophic diabetes: a study with emulsion models of chylomicrons

Clinical Endocrinology, 2004
Summarybackground  Lipoatrophic diabetes is characterized by the near absence of adipose tissue and the presence of insulin‐resistant diabetes. Fasting hypertriglyceridaemia and increased postprandial lipidaemia are also present, but the metabolism of chylomicrons, the triglyceride‐rich lipoproteins in the circulation that carry the dietary fats ...

The mechanism of the formation and secretion of chylomicrons

Atherosclerosis Supplements, 2010
The purpose of this review is to update the reader on our current understanding of the uptake and secretion of dietary lipid by the enterocyte to the periphery. This is a multi-stage process that first involves luminal digestion, followed by cellular uptake and processing, and subsequent extracellular transport of chylomicrons.

Glucagon-like peptide-2 increases intestinal lipid absorption and chylomicron production via CD36.

Gastroenterology, 2009
BACKGROUND & AIMS Excessive postprandial lipemia is a prevalent condition that results from intestinal oversecretion of apolipoprotein B48 (apoB48)-containing lipoproteins.

Characterization of chylomicron in preterm infants

Pediatrics International, 2019
AbstractBackgroundThe aim of this study was to investigate cholesterol and triglyceride levels in the chylomicron fraction of preterm infants at birth and during the early postnatal period.MethodsThe subjects consisted of 133 infants (81 boys and 52 girls): 74 were term infants born at 37–41 weeks of gestation and 59 were preterm infants born at 29–36 ...

Chylomicrons

2015
: Chylomicrons (CMs) arise solely from the intestine, and contain TG primarily of dietary origin. CMs also contain PLs, CH, CEs, and usually one fat soluble vitamin. High amounts of CMs in blood cause serum to become lactescent. Nascent CMs must acquire Apo-C from circulating HDL in order to become effective substrates for LPL (i.e., clearing factor ...

A proposed model for the assembly of chylomicrons

Atherosclerosis, 2000
The intestine synthesizes very low density lipoproteins (VLDL) and chylomicrons (CM) to transport fat and fat-soluble vitamins into the blood. VLDL assembly occurs constitutively whereas CM assembly is a characteristic property of the enterocytes during the postprandial state. The secretion of CM is specifically inhibited by Pluronic L81.

Inhibition of hepatic chylomicron remnant uptake by gene transfer of a receptor antagonist.

Science, 1994
The low density lipoprotein receptor-related protein (LRP) has been proposed to mediate in concert with the LDL receptor (LDLR) the uptake of dietary lipoproteins into the hepatocytes.
