IL-6, or cytokines of the IL-6 family using gp130 as transducer chain receptor, have been suggested to play a role in certain B lymphoid neoplasia. The presence of cell membrane gp80 and gp130 IL-6 receptors was studied in 98 patients with various leukaemia and non-Hodgkin's malignant lymphoma using flow cytofluorometry and immunohistology. Except neoplasia of immature B cells which expressed neither of the receptors, the majority of B cell tumours expressed one or both of them, mantle cell lymphoma being found to express the highest density of receptors. Using IL-6-dependent XG myeloma cell lines and mAb recognizing various gp80 and gp130 functional epitopes, it has been shown that IL-6 activation leads to a modified expression of some epitopes. In particular, the decrease or the disappearance of a gp130 epitope called A1 signed gp130 dimerization which is the first step of the gp130 activation pathway. Gp80 and gp130 epitope analysis was achieved in 17 of the patients. In four, an epitope phenotype compatible with a cytokine-induced activation was found. The cells of five B-CLL patients which expressed both gp80 and gp130 receptors were incubated with IL-6 to induce activation. In three of the cases they were found to rearrange their receptors in activated forms but not in the two others, showing that cells able to be activated or not can be found. These results confirm that gp130 signalling might play an important role in the pathogenesis of certain B cell neoplasia.
