| 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) |
| Tm cells | T helper cells that have an Fc receptor for immunoglobulin M molecules. (05 Mar 2000) |
| endocrine cells of gut | Cells found throughout the lining of the gastrointestinal tract that contain regulatory peptide hormones and/or biogenic amines. The substances are located in secretory granules and act in an endocrine or paracrine manner. Some of these substances are also found in neurons in the gut. There are at least 15 different types of endocrine cells of the gut. Some take up amine precursors and have been called apud cells. However, most endocrine cells of the gut apparently have endodermal rather than neuroectodermal origin, so the relationship with apud cells is not clear. (12 Dec 1998) |
| endodermal cells | Embryonic cell's forming the yolk sac and giving rise to the epithelium of the alimentary and respiratory tracts and to the parenchyma of associated glands. Synonym: entodermal cells. (05 Mar 2000) |
| enterochromaffin cells | Group of basal granular cells of the gut whose granules stain readily with silver and chromium salts. The cells secrete serotonin, substance p, and enkephalins. There are three types: gastric (antral mucosa), duodenal, and intestinal. (12 Dec 1998) |
| enterochromaffin-like cells | Irregular-shaped argyrophilic cells which produce histamine, chromogranin a/pancreastatin, and an as yet unidentified peptide hormone. They are the predominant endocrine cell type of the oxyntic (acid-producing) mucosa of the stomach. Ecl cells respond to gastrin by releasing their secretory products and this source of histamine acts as the positive paracrine stimulator of the release of hydrochloric acid from the parietal cell. (12 Dec 1998) |
| enteroendocrine cells | Cell's with granules that may be either argentaffinic or argyrophilic; the cell's, scattered throughout the digestive tract, are of several varieties and are believed to produce at least 20 different gastrointestinal hormones and neurotransmitters. Synonym: enterochromaffin cells, Kulchitsky cells. (05 Mar 2000) |
| entodermal cells | Embryonic cell's forming the yolk sac and giving rise to the epithelium of the alimentary and respiratory tracts and to the parenchyma of associated glands. Synonym: entodermal cells. (05 Mar 2000) |
| epithelial cells | Cells that cover the surface of the body and line its cavities. (12 Dec 1998) |
| epithelioid cells | Characteristic cells of granulomatous hypersensitivity. They appear as large, flattened cells with increased endoplasmic reticulum. They are believed to be activated macrophages that have differentiated as a result of prolonged antigenic stimulation. Further differentiation or fusion of epithelioid cells is thought to produce multinucleated giant cells (giant cells). (12 Dec 1998) |
| erythroid progenitor cells | Committed, erythroid stem cells derived from myeloid stem cells. The progenitor cells develop in two phases: erythroid burst-forming units (bfu-e) followed by erythroid colony-forming units (cfu-e). Bfu-e differentiate into cfu-e on stimulation by erythropoietin, and then further differentiate into erythroblasts when stimulated by other factors. (12 Dec 1998) |
| tubal air cells | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
