Lymphocyte surface markers in acute lymphoblastic leukemia of adults. 1977

J C Garcia, and Y H Chen, and C S Hsu

Leukemic cells from eight adult patients with acute lymphoblastic leukemia (ALL) were examined for the T-lymphocyte (T-cell) marker of sheep erythrocyte (E) receptors and for B-lymphocyte (B-cell) markers of surface immunoglobulins (SIg), complement receptors and FC receptors. Six of these patients' leukemic cells were devoid of both T- and B-cell markers, and therefore were "null" cells. The leukemic lymphoblasts of a 79-year-old patient had all B-cell markers, including monoclonal IgG K and receptors for complement and Fc. In cells from another patient (21 years old), only complement receptors were found. A review of the literature revealed that, similar to childhood ALL, adult cases of ALL were mostly of "null" cell type. All of the T-cell type was found in approximately 20% of patients. ALL of the B-cell type occurred only rarely. The latter cell type appeared to occur mainly in the middle-aged and the elderly.

UI	MeSH Term	Description	Entries
D007141	Immunoglobulin Fc Fragments	Crystallizable fragments composed of the carboxy-terminal halves of both IMMUNOGLOBULIN HEAVY CHAINS linked to each other by disulfide bonds. Fc fragments contain the carboxy-terminal parts of the heavy chain constant regions that are responsible for the effector functions of an immunoglobulin (COMPLEMENT fixation, binding to the cell membrane via FC RECEPTORS, and placental transport). This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D011947	Receptors, Antigen, B-Cell	IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
