The Diego antigen (or blood group) system is composed of 21 blood factors or antigens carried on the Band 3 glycoprotein, also known as Anion Exchanger 1 (AE1).The antigens are inherited through various alleles of the gene SLC4A1 (Solute carrier family 4), located on human chromosome 17.
Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
The low-density lipoprotein receptor (LDL-R) is a mosaic protein of 839 amino acids (after removal of 21-amino acid signal peptide) [5] that mediates the endocytosis of cholesterol-rich low-density lipoprotein (LDL).
Conversely, these antibodies are absent in people who take statin medications but do not have myopathy. Thus, the presence of anti-HMG CoA reductase antibodies in someone who uses a statin and has myopathy strongly supports the diagnosis. [3] CK levels increase to 10-100 times above normal (2000–20,000 IU/L) in more than 90% of cases.
It is caused by the presence of antibodies against anionic phospholipids and β2-glycoprotein I (β2GPI). The anti-β2GPI antibodies are most prevalent in causing the symptoms of the disease. When bound by an antibody, β2GPI begins to interact with monocytes, endothelial cells, and platelets. ApoER2 is thought to play a key role in the process ...
Hypercholesterolemia, also called high cholesterol, is the presence of high levels of cholesterol in the blood. [1] It is a form of hyperlipidemia (high levels of lipids in the blood), hyperlipoproteinemia (high levels of lipoproteins in the blood), and dyslipidemia (any abnormalities of lipid and lipoprotein levels in the blood).
Each particle contains a single apolipoprotein B-100 molecule (Apo B-100, a protein that has 4536 amino acid residues and a mass of 514 kDa), along with 80 to 100 additional ancillary proteins. Each LDL has a highly hydrophobic core consisting of polyunsaturated fatty acid known as linoleate and hundreds to thousands (about 1500 commonly cited ...
[8] [10] [11] As a member of the LDLR family, LRP1 contains cysteine-rich complement-type repeats, EGF (gene) repeats, β-propeller domains, a transmembrane domain, and a cytoplasmic domain. [9] The extracellular domain of LRP1 is the alpha-chain, which comprises four ligand -binding domains (numbered I-IV) containing two, eight, ten, and ...
