α-Naphthyl butyrate esterase, also referred to as naphthyl butyrate esterase or butyrate esterase, is a histological stain specific for white blood cells of the monocytic proliferation line. [ 1 ] References
Carboxylesterase 1 is a serine esterase and member of a large multigene carboxylesterase family. It is also part of the alpha/beta fold hydrolase family. [ 7 ] These enzymes are responsible for the hydrolysis of ester- and amide -bond-containing xenobiotics and drugs such as cocaine and heroin.
The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ratio was an estimate made in 1972; current estimates put the ratio at either 3 to 1 or 1.3 to 1. [299] The total length of capillaries in the human body is not 100,000 km.
Acquired C1 esterase inhibitor deficiency, also referred to as acquired angioedema (AAE), is a rare medical condition that presents as body swelling that can be life-threatening and manifests due to another underlying medical condition.
The enzyme 1-alkyl-2-acetylglycerophosphocholine esterase (EC 3.1.1.47) catalyzes the reaction 1-alkyl-2-acetyl-sn-glycero-3-phosphocholine + H 2 O 1-alkyl-sn-glycero-3-phosphocholine + acetate. The former is also known as platelet-activating factor. There are multiple enzymes with this function:
The enzyme protein phosphatase methylesterase-1 (EC 3.1.1.89, PME-1, PPME1; systematic name (phosphatase 2A protein)-leucine ester acylhydrolase [1] [2] catalyses the reaction [phosphatase 2A protein]-leucine methyl ester + H 2 O ⇌ {\displaystyle \rightleftharpoons } [phosphatase 2A protein]-leucine + methanol
The cells were derived from the peripheral blood of a 1-year-old human male with acute monocytic leukemia. Some of their characteristics are: [1] Expression of Fc receptor and C3b receptors while lacking surface and cytoplasmic immunoglobulins. Production of IL-1. Positive detection of alpha-naphthyl butyrate esterase and lysozymes
CD226 (Cluster of Differentiation 226), PTA1 (outdated term, 'platelet and T cell activation antigen 1') [5] or DNAM-1 (DNAX Accessory Molecule-1) [5] is a ~65 kDa immunoglobulin-like transmembrane glycoprotein expressed on the surface of natural killer cells, NK T cell, B cells, dendritic cells, hematopoietic precursor cells, platelets ...
