| invariant chain | <chemical> Noncovalently associated with class II antigens, alpha and beta chain complex; involved in the regulation of malignant cell ia function; iip31 and iip33 were synthesized by using alternative initiator methionines Synonym: II igc, ia-associated invariant chain, II invariant glycoprotein complex, class II-associated invariant chain, IIp33, IIp31, clip peptide, ln-2 antigen, ln 2 antigen, cd74 antigen, II-key, II76-92 (05 Dec 1998) |

| invariant surface glycoprotein 100 | <chemical> A stage-specific invariant surface protein in trypanosoma brucei containing an internal, serine-rich, repetitive motif; amino acid sequence given in first source; genbank y14833 Synonym: isg-100 (05 Dec 1998) |
| invasin | <enzyme> Enzyme that degrades hyaluronic acid, found in lysosomes. (18 Nov 1997) |
| invasins | Proteins produced by bacterial cells that promote bacterial penetration into mammalian cells. The invasin produced by Yersinia pseudotuberculosis seems to bind to the fibronectin receptor (_5 _1 integrin) at a site close to the fibronectin binding site, though the invasin does not have an RGD sequence. (18 Nov 1997) |
| invasion | A term that should be used with caution, although most cell biologists would follow Abercrombie in meaning the movement of one cell type into a territory normally occupied by a different cell type, some pathologists might not agree. (18 Nov 1997) |
| invasion index | An index devised by Abercrombie & Heaysman as a means to estimate the invasiveness of cells in vitro. The index is derived from measurements on confronted explants of the cells and embryonic chick heart fibroblasts growing in tissue culture: it is the ratio of the estimated movement, had the cells not been hindered and the actual movement in the zone in which collision occurs. (18 Nov 1997) |
| invasive | 1. Having the quality of invasiveness. 2. Involving puncture or incision of the skin or insertion of an instrument or foreign material into the body, said of diagnostic techniques. (18 Nov 1997) |
| invasive cancer | Cancer that has spread to surrounding tissue. (16 Dec 1997) |
| invasive carcinoma | <tumour> A neoplasm in which collections of epithelial cells infiltrate or destroy the surrounding tissue. (05 Mar 2000) |
| invasive cervical cancer | Cancer that has spread from the surface of the cervix to tissue deeper in the cervix or to other parts of the body. (12 Dec 1998) |
| invasive mole | chorioadenoma destruens |
| invasive species | Non-native species disrupting and replacing native species. (09 Oct 1997) |
| invasiveness | Degree to which an organism is able to spread through the body from a focus of infection. (09 Oct 1997) |
| invected | Having a border or outline composed of semicircles with the convexity outward; the opposite of engrailed. Origin: L. Invectus carried in. See Inveigh. Source: Websters Dictionary (01 Mar 1998) |

"Thus first Necessity invented stools." (Cowper) 3. To frame by the imagination; to fabricate mentally; to forge; in a good or a bad sense; as, to invent the machinery of a poem; to invent a falsehood. "Whate'er his cruel malice could invent." (Milton) "He had invented some circumstances, and put the worst possible construction on others." (Sir W. Scott) Synonym: To discover, contrive, devise, frame, design, fabricate, concoct, elaborate.
