We have studied the expression of cytokine receptors CD25 (IL‐2Rα, 55 kD), CD116 (hGM‐CSFR, 145 kD), CD117 (CSFR, 145 kD), CD120a (TNFR, 55 kD), CD120b (TNFR, 75 kD), CD121a (IL‐1R, type I, 80 kD), CDw123 (IL‐3R), CD124 (IL‐4R, 140 kD), CD126 (IL‐6R, 80 kD), CD127 (IL‐7R, 75 kD), CDw128 (IL‐8R), CD130 (gp130 subunit), CDw131 (common β), CD132 (IL‐2Rγ), CD134 (OX40) and also CD95 (Fas antigen) on the lymphoid leukaemic cells. Cells from peripheral blood or bone marrow of 24 patients with disorders in lymphoid lineage mostly included acute lymphoid leukaemias (with a high leukocyte count and percentage of blasts) were analysed for the expression of surface membrane molecules by the immunofluorescence method evaluated by flow cytometry. The findings indicate that some monoclonal antibodies have a reactivity against cytokine receptors of pathological cells in individual cases, but with very variable qualitative and quantitative expression (number copies/cell). The lymphoid leukaemic cells demonstrate unique cytokine receptor profiles, which reveal the great diversity of immunophenotypes within the main functional characterisation of T and B lymphoproliferative malignancies.
