H-rosette formation in T-cell-proliferative diseases. 1975

P J Sheldon, and E J Holborow

In health up to 6% of human lymphocytes will form rosettes with homologous group O rhesus-negative erythrocytes (H rosettes). Increased numbers of H rosettes were found in T-cell-proliferative diseases-- namely, infectious mononucleosis, Sézary's syndrome, and T-cell leukaemia. H-rosette formation is thus a marker for a subpopulation of T lymphocytes, and this easily performed test of T-cell activation may have clinical value in characterising changes in blood lymphocyte populations in disease.

UI	MeSH Term	Description	Entries
D007104	Immune Adherence Reaction	A method for the detection of very small quantities of antibody in which the antigen-antibody-complement complex adheres to indicator cells, usually primate erythrocytes or nonprimate blood platelets. The reaction is dependent on the number of bound C3 molecules on the C3b receptor sites of the indicator cell.

D007244	Infectious Mononucleosis	A common, acute infection usually caused by the Epstein-Barr virus (HERPESVIRUS 4, HUMAN). There is an increase in mononuclear white blood cells and other atypical lymphocytes, generalized lymphadenopathy, splenomegaly, and occasionally hepatomegaly with hepatitis.

D007518	Isoantibodies	Antibodies from an individual that react with ISOANTIGENS of another individual of the same species.	Alloantibodies
D007945	Leukemia, Lymphoid	Leukemia associated with HYPERPLASIA of the lymphoid tissues and increased numbers of circulating malignant LYMPHOCYTES and lymphoblasts.

D007959	Lymphocyte Culture Test, Mixed	Measure of histocompatibility at the HL-A locus. Peripheral blood lymphocytes from two individuals are mixed together in tissue culture for several days. Lymphocytes from incompatible individuals will stimulate each other to proliferate significantly (measured by tritiated thymidine uptake) whereas those from compatible individuals will not. In the one-way MLC test, the lymphocytes from one of the individuals are inactivated (usually by treatment with MITOMYCIN or radiation) thereby allowing only the untreated remaining population of cells to proliferate in response to foreign histocompatibility antigens.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D003078	Colchicine	A major alkaloid from Colchicum autumnale L. and found also in other Colchicum species. Its primary therapeutic use is in the treatment of gout, but it has been used also in the therapy of familial Mediterranean fever (PERIODIC DISEASE).	Colchicine, (+-)-Isomer,Colchicine, (R)-Isomer
