|---|---|---|---|
| 설명 | B형 간염이나 비A형－비B형 간염의 속발증으로 나타나는 간의 만성염증이다. 같은 형태의 병이 선천성 또는 후천감마글로불린결핍증이나 어떤 종류의 약물 투여에 수반해서 나타날 수도 있다. 특징적으로 문맥부에 형질세포와 큰포식세포의 침윤, 조각괴사(간소엽 주변부 간세포의 파괴) 및 섬유증 등의 조직소견을 나타낸다. 병의 경과는 매우 다양하며 장기간의 무증상기를 보일 수도 있고 그 사이 사이에 황달, 전신쇠약, 식욕부진 및 발열 등의 증상이 나타나는 수가 있으며, 또 무월경증, 관절염, 피부발진, 혈관염, 갑상샘염, 콩팥사구체염, 궤양성대장염, 쉐그렌증후군 등 간 이외의 증상이 나타나는 수도 있고, 간경화증과 간기능상실로 진행되는 수도 있다. 자가면역메커니즘이 관여되는 것으로 추측되고 있다. |

| active repressor | A repressor that combines directly with an operator gene to repress the operator and its structural genes, thus repressing protein synthesis; active repressor may be repressed by an inducer, with resulting protein synthesis; a homeostatic mechanism for regulation of inducible enzyme systems. (05 Mar 2000) |

| repressor | A type of protein molecule that binds to DNA that shuts up transcription of a gene. See: operon or operator. (09 Oct 1997) |
|---|---|
| repressor gene | A gene that prevents a nonallele from being transcribed. (05 Mar 2000) |
| repressor protein | <molecular biology> A protein that binds to an operator of a gene preventing the transcription of the gene. The binding affinity of repressors for the operator may be affected by other molecules. Inducers bind to repressors and decrease their binding to the operator, while co repressors increase the binding. The paradigm of repressor proteins is the lactose repressor protein that acts on the lac operon and for which the inducers are _ galactosides such as lactose, it is a polypeptide of 360 amino acids that is active as a tetramer. Other examples are the lambda repressor protein of lambda bacteriophage that prevents the transcription of the genes required for the lytic cycle leading to lysogeny and the cro protein, also of lambda, which represses the transcription of the lambda repressor protein establishing the lytic cycle. Both of these are active as dimers and have a common structural feature the helix turn helix motif that is thought to bind to DNA with the helices fitting into adjacent major grooves. (18 Nov 1997) |
| repressor proteins | Proteins which are normally bound to the operator locus of an operon, thereby preventing transcription of the structural genes. In enzyme induction, the substrate of the inducible enzyme binds to the repressor protein, causing its release from the operator and freeing the structural genes for transcription. In enzyme repression, the end product of the enzyme sequence binds to the free repressor protein, the resulting complex then binds to the operator and prevents transcription of the structural genes. (12 Dec 1998) |
| met repressor operator complex | Repressor protein, 104 residues, product of the metJ gene, which regulates methionine biosynthesis in E. Coli. Dimeric molecules bind to adjacent sites 8 base pairs apart on the DNA, sequence recognition is by interaction between antiparallel strands of protein and the major groove of the B form DNA duplex. (18 Nov 1997) |
| inactive repressor | A repressor that cannot combine with an operator gene until it has combined with a corepressor (usually a product of a protein pathway); after activation, the repressor arrests production of the proteins controlled by the operator gene; a homeostatic mechanism for regulation of repressible enzyme systems. Synonym: aporepressor. (05 Mar 2000) |
| translational repressor | A molecule that blocks translation by binding to a messenger RNA. (09 Oct 1997) |
| lactose repressor | Protein (tetramer of 37 kD subunits) that normally binds with very high affinity to the operator region of the lactose operon and inhibits transcription of the downstream genes by blocking access of the polymerase to the promoter region. When the lactose repressor binds allolactose, its binding to the operator is reduced and the gene set is derepressed. (18 Nov 1997) |
| active | Characterised by action, not passive, not expectant. (18 Nov 1997) |
| active acetate | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
| active aldehyde | Any aldehyde derivative of thiamin pyrophosphate. (05 Mar 2000) |
| active anaphylaxis | Reaction following inoculation of antigen in a subject previously sensitised to the specific antigen, in contrast to passive anaphylaxis. (05 Mar 2000) |
| active biomass | <cell biology> The amount of a given culture that is actively growing. (06 May 1997) |
| active carbon dioxide | Activated carbon dioxide, a complex of N-carboxybiotin (biotin + CO2) and an enzyme; the form in which carbon dioxide is added to other molecules in carboxylations; e.g., to methylcrotonyl-CoA to form beta-methylglutaconyl in the catabolism of leucine, and to acetyl-CoA to form malonyl-CoA. See: acetyl-CoA carboxylase. (05 Mar 2000) |
