Clinical immunological study of T lymphocytes and EA rosette forming cells in tonsils. 1978

L Gyeney, and K Merétey, and A Falus, and U Böhm, and S Bozsóky

Tonsillar E and EA rosette forming lymphocyte subpopulations were studied in 120 tonsillectomized patients. T cell ratios was usually lower in the tonsils than in the blood. EA binding cells were studied with indicator systems of human or rabbit antibody sensitized red cells, respectively. Poorly sensitized human RBCs (EArabbit) bind much better to tonsillar cells than to blood lymphocytes and so this system proved to be specially suitable to study tonsillar EA binding cells. Increase in E and EA rabbit rosette forming cell frequencies were found with the age of patients. Decrease in percentage of T cells and EA rabbit rosette binding cells were found with high frequency of acut tonsillitis and with clinical sysmptoms of chronic local inflammation. The variation of these lymphocyte subpopulations with the local tonsillar inflammatory processes suggest a considerable clinical immunological role of local T cells and of this portion of Fc receptor postive lymphocytes.

D000367	Age Factors	Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance.

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
D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
