| RTG-2 | rainbow trout gonadal tissue cells |
| olfactory cells | Very slender nerve cell's, with large nuclei and surmounted by six to eight long, sensitive cilia in the olfactory epithelium at the roof of the nose; they are the receptors for smell. Synonym: olfactory cells, Schultze's cells. (05 Mar 2000) |

| olfactory receptor cells | Very slender nerve cell's, with large nuclei and surmounted by six to eight long, sensitive cilia in the olfactory epithelium at the roof of the nose; they are the receptors for smell. Synonym: olfactory cells, Schultze's cells. (05 Mar 2000) |
| oligodendroglia cells | See: oligodendroglia. (05 Mar 2000) |
| oxyphil cells | Cell's of the parathyroid gland that increase in number with age; the cytoplasm contains numerous mitochondria and stains with eosin. Similar cell's, and tumours composed of them, are found in salivary glands and the thyroid; in the latter, also called Hurthle cell's. (05 Mar 2000) |
| tanned red cells | Erythrocytes subjected to mild treatment with chemicals such as tannic acid so that they adsorb onto their surface soluble antigens; used in haemagglutination tests. (05 Mar 2000) |
| taste cells | Darkly staining cell's in a taste bud that appear to have extending into the gustatory pore long hair-like microvilli containing a number of closely packed microtubules; the taste cell's stand in synaptic contact with sensory nerve fibres of the facial, glossopharyngeal, or vagus nerves. Synonym: gustatory cells. (05 Mar 2000) |
| T cytotoxic cells | Lymphocyte-like effector cells which mediate antibody-dependent cell cytotoxicity. They kill antibody-coated target cells which they bind with their fc receptors. (12 Dec 1998) |
| TDTH cells | A functional subset of T helper cells that are involved in delayed-type hypersensitivity reactions. (05 Mar 2000) |
| tendon cells | Elongated fibroblastic cell's arranged in rows between the collagenous tendon fibres. (05 Mar 2000) |
| Tg cells | A subset of T-cells that have an Fc receptor for immunoglobulin G molecules. (05 Mar 2000) |
| th1 cells | Subset of helper-inducer T-lymphocytes which synthesise and secrete interleukin-2, gamma-interferon, and interleukin-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, th1 cells are associated with vigorous delayed-type hypersensitivity reactions. (12 Dec 1998) |
| th2 cells | Subset of helper-inducer T-lymphocytes which synthesise and secrete the interleukins il-4, il-5, il-6, and il-10. These cytokines influence B-cell development and antibody production as well as augmenting humoral responses. (12 Dec 1998) |
| theca cells | The connective tissue cells of the graafian follicle. (12 Dec 1998) |
| theca cells of stomach | Cell's lining the gastric surface and foveolae; a glycoprotein product at the apical end of each cell is secreted and forms a mucous protective film. Synonym: theca cells of stomach. (05 Mar 2000) |
| T helper cells | A subset of lymphocytes that secrete various cytokines that regulate the immune response. (05 Mar 2000) |
