| cellular oncogene | <molecular biology> A normal gene that, when mutated or improperly expressed, can cause cancer to develop. (09 Oct 1997) |
|---|---|
| cellular pathology | The interpretation of diseases in terms of cellular alterations, i.e., the ways in which cells fail to maintain homeostasis, sometimes used as a synonym for cytopathology. (05 Mar 2000) |
| cellular polyp | A polyp that consists of benign neoplastic tissue derived from glandular epithelium. Synonym: cellular polyp, polypoid adenoma. (05 Mar 2000) |
| cellular respiration | <biochemistry> The conversion within the cell of nutrients (such as sugar molecules) into chemical energy in the form of ATP, by reacting the food with oxygen (O2) until the food has completely been degraded into carbon dioxide and H2O. (09 Oct 1997) |
| cellular retinoic acid binding protein | <protein> A cytoplasmic fatty acid binding protein that acts as an initial receptor for the putative morphogen, retinoic acid. (18 Nov 1997) |
| cellular slime mould | See: Acrasidae. (18 Nov 1997) |
| cellular tumour | A tumour composed mainly of closely packed cells. (05 Mar 2000) |
| immunity, cellular | Those manifestations of the immune response which are mediated by antigen-sensitised T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role. (12 Dec 1998) |
| affinity antibody | The measure of the interaction between molecules such as a receptor and its ligand. This interaction is reversible. (05 Mar 2000) |
| agglutinating antibody | 1. An antibody that causes clumping or agglutination of the bacteria or other cells which either stimulated the formation of the agglutinin, or contain immunologically similar, reactive antigen. Synonym: agglutinating antibody, immune agglutinin. 2. A substance, other than a specific agglutinating antibody, that causes organic particles to agglutinate, commonly qualified, e.g., plant agglutinin. (05 Mar 2000) |
| anaphylactic antibody | Antibody that has an affinity for certain kinds of cells, in addition to and unrelated to its specific affinity for the antigen that induced it, because of the properties of the Fc portion of the heavy chain. See: heterocytotropic antibody, homocytotropic antibody, cytotropic antibody test. Synonym: anaphylactic antibody, cytophilic antibody. (05 Mar 2000) |
| anti-basement membrane antibody | Autoantibodies to renal glomerular basement membrane antigens. (05 Mar 2000) |
| antibody | An immunoglobulin molecule that has a specific amino acid sequence by virtue of which it interacts only with the antigen that induced its synthesis in cells of the lymphoid series (especially plasma cells) or with antigen closely related to it. Antibodies are classified according to their ode of action as agglutinins, bacteriolysins, haemolysins, opsonins, precipitins, etc. (18 Nov 1997) |
| antibody affinity | A measure of the binding strength between antibody and a simple hapten or antigen determinant. It depends on the closeness of stereochemical fit between antibody combining sites and antigen determinants, on the size of the area of contact between them, and on the distribution of charged and hydrophobic groups. It includes the concept of "avidity," which refers to the strength of the antigen-antibody bond after formation of reversible complexes. (12 Dec 1998) |
| antibody aldolase | <enzyme> Prepared by reactive immuninization to catalyze a wide variety of aldol reactions and decarboxylations Registry number: EC 4.1.2.- Synonym: fab 33f12, aldolase catalytic antibody (26 Jun 1999) |
