Human lymphocyte and mouse erythrocyte rosettes. Optimization of the assay. 1981

P Hokland, and J Ellegaard, and I Heron

Rosettes formed between lymphocytes and unsensitized mouse erythrocytes not only detect a subset of normal b-lymphocytes, but furthermore seem to be of considerable importance in the differential diagnosis of various B cell malignancies. From a series of experiments aimed at optimizing this rosette test, we conclude: (1) Erythrocytes from different mouse strains vary in their affinity for lymphocytes; (2) Experimental conditions are less strict when testing chronic lymphatic leukaemia lymphocytes than normal lymphocytes; (3) Treatment with the sulphydryl compound aminoethyl-isothiouronium bromide, which enhances sheep erythrocyte rosette formation, has an opposite effect on mouse rosettes, and (4) Neuraminidase treatment of the lymphocytes is not necessary when optimal experimental conditions are used.

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
D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
