[Effect of the serum of patients with cholestasis on lymphocyte E rosette formation]. 1977

Sera from cholestatic patients have been found to interfere with lymphocyte rosette formation (E rosettes). Lymphocytes from patients with cholestasis showed a lower percentage (42.36%) of cells binding sheep red blood cells in comparison with a control group (62%). In the presence of cholestatic serum the number of E rosettes formed by lymphocytes from normal subjects declined to 44.16%. This behaviour, however, can reverse, since lymphocytes from cholestatic patients previously incubated with normal serum, showed a nearly normal capability of forming E rosettes (57.90%). Therefore, it is conceivable that among the several factors which are present in sera from patients with either chronic or acute hepatitis and which are able to interfere with T-lymphocyte function, there may be included also the factor which is present in sera from cholestatic patients. The possible role of bile salts and hyperlipoproteinaemia present in those patients requires further investigation.

UI MeSH Term Description Entries
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D002779 Cholestasis Impairment of bile flow due to obstruction in small bile ducts (INTRAHEPATIC CHOLESTASIS) or obstruction in large bile ducts (EXTRAHEPATIC CHOLESTASIS).

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012397 Rosette Formation The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells. Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
