| Langerhans' cells | Dendritic clear cell's in the epidermis, containing distinctive granules that appear rod-or racket-shaped in section, but lacking tonofilaments, melanosomes, and desmosomes; they carry surface receptors for immunoglobulin (Fc) and complement (C3), and are believed to be antigen fixing and processing cell's of monocytic origin; active participants in cutaneous delayed hypersensitivity.

| Langhans' cells | Multinucleated giant cell's seen in tuberculosis and other granulomas; the nuclei are arranged in an arciform manner at the periphery of the cell's. Synonym: Langhans'-type giant cells. Synonym: cytotrophoblastic cells. (05 Mar 2000) |

| foveolar cells of stomach | Theca cell's of the foveolae of the stomach. (05 Mar 2000) |
| Leishman's chrome cells | Basophilic granular leukocytes (basophils) observed in the circulating blood of some persons with blackwater fever. (05 Mar 2000) |
| lepra cells | Distinctive, large, mononuclear phagocytes (macrophages) with a foamlike cytoplasm, and also poorly staining saclike structures resulting from degeneration of such cell's, observed characteristically in leprous inflammatory reactions; indistinct staining results from numerous, fairly closely packed leprosy bacilli, which are acid-fast and resistant to staining by ordinary methods but may be vividly demonstrated by acid-fast staining procedures. (05 Mar 2000) |
| fusiform cells of cerebral cortex | Spindle-shaped cell's in the sixth layer of the cerebral cortex. (05 Mar 2000) |
| leydig cells | Cells in the interstitial tissue of the testis that are believed to furnish the internal secretion of that gland. (12 Dec 1998) |
| Leydig's cells | lutropin |
| light cells of thyroid | Cell's present between follicles or interspersed among follicular cell's; they are rich in mitochondria and are believed to be the source of thyrocalcitonin. Synonym: C cell, light cells of thyroid. (05 Mar 2000) |
| llc-pk1 cells | Renal epithelial cell line originally derived from porcine kidneys. It is used for pharmacologic and metabolic studies. (12 Dec 1998) |
| lutein cells | The cells of the corpus luteum which are derived from the granulosa cells and the theca cells of the graafian follicle. (12 Dec 1998) |
| acetyl-CoA:alpha-glucosaminide acetyltransferase | <enzyme> An enzyme involved in the synthesis of certain carbohydrate moieties on proteins. A deficiency of this enzyme leads to mucopolysaccharidosis type III C. (05 Mar 2000) |
| adrenergic alpha-agonists | Drugs that selectively bind to and activate alpha adrenergic receptors. (12 Dec 1998) |
| adrenergic alpha-antagonists | Drugs that bind to but do not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous adrenergic agonists. Adrenergic alpha-antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma. (12 Dec 1998) |
