| chemodifferentiation | Differentiation of the cellular chemical constituents in the embryo prior to cytodifferentiation; sometimes recognizable histochemically. Synonym: invisible differentiation. (05 Mar 2000) |
|---|---|
| chemodynesis | Induction of cytoplasmic streaming in plant cells by chemicals rather than by light (photodynesis). (18 Nov 1997) |
| chemoembolization, therapeutic | Administration of antineoplastic agent together with an embolizing vehicle. This allows slow release of the agent as well as obstruction of the blood supply to the neoplasm. (12 Dec 1998) |
| chemoheterotroph | Synonym: chemoorganotroph. Origin: chem-+ G. Heteros, other, + trophe, nourishment (05 Mar 2000) |
| chemoheterotrophic | Pertaining to a chemoorganotroph. Synonym: chemoheterotrophic. (05 Mar 2000) |
| chemoimmunology | <chemistry, immunology> A subfield of chemistry that is concerned with the study of the chemical activity involved with immunological processes. (09 Oct 1997) |
| chemokine | Cytokines that are chemotactic for leucocytes. The first member of the family was IL-8 interleukin-8) but subsequently many other members have been identified. They can now be sub divided into two groups on the basis of the arrangement of a pair of conserved cysteines: the C x C group includes platelet Factor 4, platelet basic protein, interleukin 8, melanoma growth stimulatory protein, macrophage inflammatory protein 2, the C C group contains (18 Nov 1997) |
| chemokine receptor | A molecule that receives a chemokine and a chemokine dock. Several chemokine receptors are essential co-receptors for HIV. (12 Dec 1998) |
| chemokines | Class of pro-inflammatory cytokines that have the ability to attract and activate leukocytes. They can be divided into at least three structural branches: c (chemokines, c), cc (chemokines, cc), and cxc (chemokines, cxc), according to variations in a shared cysteine motif. (12 Dec 1998) |
| chemokines, c | Group of chemokines without adjacent cysteines that are chemoattractants for lymphocytes only. (12 Dec 1998) |
| chemokines, cc | Group of chemokines with adjacent cysteines that are chemoattractants for lymphocytes, monocytes, eosinophils, basophils but not neutrophils. (12 Dec 1998) |
| chemokines, cxc | Group of chemokines with paired cysteines separated by a different amino acid. Cxc chemokines are chemoattractants for neutrophils but not monocytes. (12 Dec 1998) |
| chemokinesis | A response by a motile cell to a soluble chemical that involves an increase or decrease in speed (positive or negative orthokinesis) or of frequency of movement or a change in the frequency or magnitude of turning behaviour (klinokinesis). (18 Nov 1997) |
| chemokinetic | Referring to chemokinesis. (05 Mar 2000) |
| chemolithotroph | An organism which obtains its energy from the oxidation of inorganic compounds. (09 Oct 1997) |
