| human t-lymphotropic virus | <virology> Type i: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which causes adult T-cell leukaemia and T-cell lymphoma and may also be involved in certain demyelinating diseases (diseases where the protective myelin sheath around nerve fibres are destroyed). HTLV-I is closely related to HTLV-II (60% of their genomes are identical). Type II: A human, single-stranded RNA retrovirus from the subfamily Oncovirinae which may cause diseases such as T-cell leukaemia and T-cell lymphoma (but this has not been proven). HTLV-II is closely related to HTLV I (60% of their genomes are identical). Type III: An obsolete term for human immunodeficiency virus (HIV), which causes Acquired Immunity Deficiency Syndrome (AIDS). Acronym: HTLV (09 Oct 1997) |

| liquid human serum | The pool of fluids separated from blood withdrawn from human subjects and allowed to clot in the absence of any anticoagulant; not more than 10 separate donations are pooled; the contributions from donors of A, O, and either B or AB groups are represented in approximately the ratio 9:9:2. (05 Mar 2000) |
| acetoacetyl-acyl carrier protein synthase | <enzyme> E coli enzyme, that catalyses condensation of malonyl-acyl carrier protein plus acetyl-acyl carrier protein; not inhibited by cerulenin Registry number: EC 2.3.1.- Synonym: acetoacetyl-acp synthase (26 Jun 1999) |
| acid soluble spore protein | <molecular biology> A DNA binding protein in the spores of some bacteria, thought to stabilise the DNA in an A configuration, so protecting it from cleavage by enzymes or UV light. (18 Nov 1997) |
| acute-phase protein | <haematology> These plasma proteins (in addition to fibrinogen) increase 25% or more in response to inflammation and injury are under direct control of interleukin-6 (IL-6) (hepatocyte-stimulating factor). Other proteins which increase are ceruloplasmin, C3 and C4 which increase 50% or more; alpha-1 acid glycoprotein, alpha-1 antitrypsin, haptoglobin and fibrinogen (the major determinant of viscosity 1 ) which increase two- to fourfold; C-reactive protein (CRP) and serum amyloid A which increase several hundred-fold. Despite long-held clinical opinion to the contrary, available data indicate that neither ESR nor measurement of specific acute-phase reactants are useful in excluding underlying infection or inflammation regardless of the pretest probability. These proteins are secreted into the blood in increased or decreased quantities by hepatocytes in response to trauma, inflammation, or disease. They can serve as inhibitors or mediators of the inflammatory processes. Certain acute-phase proteins have been used to diagnose and follow the course of diseases or as tumour markers. See also: amyloid, c-reactive protein, erythrocyte sedimentation rate, viscosity. (25 Jun 1999) |
| acyl-(acyl-carrier-protein)-phospholipid acyltransferase | <enzyme> Catalyses the formation of phosphatidylethanolamine from acyl-acyl carrier protein and 2-acyl-sn-glycero-3-phosphoethanolamine Registry number: EC 2.3.1.40 Synonym: 2-acyl-gpe acyltransferase, 2-acylglycerophosphoethanolamine acyltransferase (26 Jun 1999) |
