Murine monoclonal antibodies to the myelin-associated glycoprotein react with large granular lymphocytes of human blood.

Monoclonal antibodies prepared to human myelin-associated glycoprotein were shown to react with a population of human peripheral blood mononuclear cells. The population is similar to the large granular lymphocytes or natural killer cells defined by antibody Leu 7 (also called HNK-1). The population also includes cells exhibiting the Leu 2 marker for suppressor/cytotoxic T cells. The results indicate a shared antigenicity between the nervous system and the immune system and may be relevant to the pathogenesis of demyelinating diseases.

Phorbol ester-induced changes in human leukemic pre-B lines.

The genomic analysis of four non-T-leukemic lines NALM-1, KM-3, NALL-1, and NALM-16 shows a rearranged configuration of the immunoglobulin mu chain genes, indicating that they represent early B stages of differentiation. The differentiative potential of these pre-B cell lines was tested using the phorbol ester tumor promoter 12-O-tetradecanoyl phorbol-13-acetate (TPA). Phenotypic changes in the immunological marker profile (induction of BA-1 and BA-2 antigens) are observed, presumably reflecting events occurring in precursor B cells. However, no maturation to immunoglobulin mu chain production could be obtained. The limited maturation can be explained on the basis of possible aberrant mu chain gene rearrangements, or other mechanisms of a regulatory nature, preventing the transcription and/or the translation of rearranged mu chain genes.
