Dual B and T markers in acute and chronic lymphocytic leukemia.

Abstract

Leukemic cells from 20 patients with chronic lymphocytic leukemia (CLL) and 60 patients with acute lymphocytic leukemia (ALL) were studied for T- and B-lymphocyte cell surface membrane markers. B-cell markers included surface membrane immunoglobulin, erythrocyte-antibody complement rosette formation, and B-cell (a-like or HLA-DR) antigens detected by a B-cell antiserum. T-cell markers included spontaneous sheep red blood cell rosette formation and a cytotoxic reaction to a specific T-cell antiserum. Seven patients with CLL and two with ALL had dual B and T markers. We propose that dual B- and T-cell markers are more common in CLL and ALL patients than previously reported. With newer and more sensitive tests for identification of B and T cells, this observation may be recognized more frequently.

Antibody Specificity

Antibodies produced by B cells are highly specific for antigen as a result of random gene recombination and somatic hypermutation and affinity maturation. As the main effector of the humoral immune system, antibodies can neutralize foreign cells. Find the latest research on antibody specificity here.
