"Chylomicron Remnants" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. CMRS abbreviation stands for Chylomicron Remnants. Metabolic products of chylomicron particles in which TRIGLYCERIDES have been selectively removed by the LIPOPROTEIN LIPASEThese remnants carry dietary lipids in the blood and are cholesterol-rich. ance of chylomicron remnants from the circulation has been found to be correlated with the progression of athero-sclerotic lesions [6–8]. Chylomicron Remnant: When the triglyceride reserve consumes (distributed), it converts APOC2 back to HDL (which APOE retains), leaving chylomicrons remnants of only 20-50 nm. Chylomicron remnants were removed at a rate of ~50% per pass in WT mice. Setting : An 800 bed general municipal hospital. (1997). 1. pro-atherogenic chylomicron remnants in plasma. cofactor for membrane-bound lipoprotein lipase which breaks down TAGs in chylomicron. Very low-density lipoprotein, or VLDL: Produced primarily by the liver, with smaller amounts contributed by the intestine. CR abbreviation stands for Chylomicron remnants. Other articles where Chylomicron is discussed: blood: Plasma: …the blood are known as chylomicrons and consist largely of triglycerides; after absorption from the intestine, they pass through lymphatic channels and enter the bloodstream through the thoracic lymph duct. Let’s compare Chylomicrons with other terms. The line at the left in the illustration represents the hepatocyte membrane. These experiments, together with studies performed in cultured cells, have demonstrated that plasma clearance of chylomicron remnants is a two-step process. Chylomicron Remnants (n.). Chylomicron remnants injectedintotheintact ratweretakenupbytheliver toanappreciableextent. Rats were fed corn oil to induce production and secretion of chylomicrons and were then injected with polyclonal antiserum raised against hepatic lipase to specifically and quantitatively inhibit hepatic lipase activity in vivo. Author information: (1)Franz Volhard Clinic, HELIOS Kliniken Berlin, Medical Faculty of the Charité, Humboldt University, Wiltbergstrasse 50, 13125, Berlin-Buch, Germany. Chylomicron remnants arise from the hydrolytic action of lipoprotein lipase on chylomicrons, triacylglycerol-rich lipoproteins which enter the blood from the intestine after a fat-enriched meal [9,10]. To gain a detailed understanding of those factors that govern the processing of dietary-derived lipoprotein remnants by macrophages we examined the uptake and degradation of rat triacylglycerol-rich chylomicron remnants and rat cholesterol-rich beta-very low density lipoprotein (beta-VLDL) by J774 cells and primary cultures of mouse peritoneal macrophages. A lipoprotein particle that is derived from a mature chylomicron particle by the removal of triglycerides from the chylomicron core by lipoprotein lipase and the subsequent loss of surface components. Journal of the American College of Nutrition: Vol. After a fatty meal, the blood is so full of chylomicrons that it looks milky. (1975) havealso shown substantial uptake ofremnanttriacylglycerol. ... by loosing Apo CII, the remnants are able to exit the capillaries and they travel to the liver, where they bind to either LRP receptors or LDL receptors once bound to the receptor, it is taken in … Hence, this is also a difference between chylomicrons and VLDL. chylomicron [ki″lo-mi´kron] a particle of the class of lipoproteins responsible for the transport of exogenous cholesterol and triglycerides from the small intestine to tissues after meals. Chylomicrons are spherical particles with a core of triglycerides surrounded by a layer of phospholipids, cholesterol, and apolipoproteins. The diameter of a chylomicron is 75-1200 nm while the diameter of a VLDL is 30-80 nm. by muscles , remains in more cholesterol - rich chylomicron remnants, which are taken up from the bloodstream by the ... Familiale dysbetalipoproteïnemie... uit het chylomicron gehaald . Chylomicron remnants bound to rabbit alveolar macrophages with high-affinity (Kd = 3.3 ± 0.71 μg of protein/mL). It characteristically contains apolipoprotein E (APOE) and is cleared from the blood by the liver. Rat lymph chylomicrons and chylomicron remnants were treated with trypsin or Pronase. The small particles are remnants. (1975), andFelts etal. 170 ever, little informationhas been provided aboutthe The resulting chylomicron remnants, which are cholesterol-rich lipoproteins, are subsequently taken up in the liver. What happens to chylomicron remnants after fat absorption has occured? The consequences of hepatic lipase treatment of chylomicron remnants were studied. The binding of chylomicron remnants was competitively inhibited in the presence of unlabeled remnants and to a lesser extent by unlabeled low-density lipoproteins. If you would like to request a video or topic to be made, leave a comment in the comment section below and I will try to cover it! What is the abbreviation for Chylomicron Remnants? "Chylomicron Remnants" is a descriptor in the National Library of Medicine's controlled vocabulary thesaurus, MeSH (Medical Subject Headings).Descriptors are arranged in a hierarchical structure, which enables searching at various levels of specificity. 429-34. The small circle at the top left represents a chylomicron remnant (CMR) and the one just below it is the remnant of VLDL called intermediate density lipoprotein (LDL).
