| receptors, transferrin | Membrane glycoproteins found in high concentrations on iron-utilizing cells. They specifically bind iron-bearing transferrin, are endocytosed with its ligand and then returned to the cell surface where transferrin without its iron is released. (12 Dec 1998) |
|---|---|
| receptors, transforming growth factor beta | Cell-surface proteins that bind transforming growth factor beta and trigger changes influencing the behaviour of cells. Two types of transforming growth factor receptors have been recognised. They differ in affinity for different members of the transforming growth factor beta family and in cellular mechanisms of action. Transforming growth factor alpha binds to the same receptors as epidermal growth factor (see receptors, epidermal growth factor-urogastrone). (12 Dec 1998) |
| receptors, tumour necrosis factor | Cell surface receptors that bind tumour necrosis factor and trigger changes which influence the behaviour of cells. The two recognised tumour necrosis factor receptors are designated alpha and beta receptors. Both receptors bind both alpha and beta tumour necrosis factors with high affinity, and both are members of the nerve growth factor receptor family. (12 Dec 1998) |
| receptors, vasoactive intestinal peptide | Cell surface proteins that bind vasoactive intestinal peptide (vip) with high affinity and trigger intracellular changes which influence the behaviour of cells. (12 Dec 1998) |
| receptors, vasopressin | Specific molecular sites or structures on or in cells that vasopressins react or to which they bind in order to modify the function of the cells. Two types of vasopressin receptor exist, the v1 receptor and the v2 receptor. The v1 receptor can be subdivided into v1a and v1b (formerly v3) receptors. (12 Dec 1998) |
| receptors, very late antigen | Members of the integrin family appearing late after T-cell activation. They are a family of proteins initially identified at the surface of stimulated T-cells, but now identified on a variety of cell types. At least six vla antigens have been identified as heterodimeric adhesion receptors consisting of a single common beta-subunit and different alpha-subunits. (12 Dec 1998) |
| receptors, virus | Specific molecular components of the cell capable of recognizing and interacting with a virus, and which, after binding it, are capable of generating some signal that initiates the chain of events leading to the biological response. (12 Dec 1998) |
| receptors, vitronectin | Alpha-v beta-3 integrins that bind vitronectin with high affinity and play a role in cell migration. They also bind fibrinogen, von willebrand factor, osteopontin, and thrombospondin. The highly homologous alpha-v beta-5 integrin also binds vitronectin, but mediates simple adhesion. (12 Dec 1998) |
| receptosomes | Vesicles that avoid lysosomes and deliver their contents to other intracellular sites. (05 Mar 2000) |
| recess | 1. A withdrawing or retiring; a moving back; retreat; as, the recess of the tides. "Every degree of ignorance being so far a recess and degradation from rationality." (South) "My recess hath given them confidence that I may be conquered." (Eikon Basilike) 2. The state of being withdrawn; seclusion; privacy. "In the recess of the jury they are to consider the evidence." (Sir M. Hale) "Good verse recess and solitude requires." (Dryden) 3. Remission or suspension of business or procedure; intermission, as of a legislative body, court, or school. "The recess of . . . Parliament lasted six weeks." (Macaulay) 4. Part of a room formed by the receding of the wall, as an alcove, niche, etc. "A bed which stood in a deep recess." (W. Irving) 5. A place of retirement, retreat, secrecy, or seclusion. "Departure from his happy place, our sweet Recess, and only consolation left." (Milton) 6. Secret or abstruse part; as, the difficulties and recesses of science. 7. <botany> A sinus. Origin: L. Recessus, fr. Recedere, recessum. See Recede. Source: Websters Dictionary (01 Mar 1998) |
| recession | A withdrawal or retreating. See: retraction. Origin: L. Recessio (see recessus) (05 Mar 2000) |
| recessitivity | The state of being recessive. (05 Mar 2000) |
| recessive | <genetics> An allele or mutation that is only expressed phenotypically when it is present in the homozygous form. In the heterozygote it is obscured by dominant alleles. (18 Nov 1997) |
| recessive character | An inherited character determined by an allele in homozygous state only. See: dominance of traits. (05 Mar 2000) |
| recessive gene | A gene that is expressed onlywhen it is present in two copies or if theother copy is missing. (09 Oct 1997) |

| recombinant |
An organism whose genome contains integrated genetic material from a different organism. Also used in relation to compounds produced by laboratory or industrial cultures of genetically engineered living cells. The cells' genes have been altered to give the capability of producing large quantities of the desired compound for use as a medical treatment. Recombinant compounds are often altered versions of naturally occurring substances.
