Ganglioside expression on cytotoxic T lymphocytes induced against the mouse erythroleukaemia line FBL‐3N, was analysed, compared with that of naive T lymphocytes in the thymus, lymph nodes and spleen. Although normal uncultured and cultured T lymphocytes expressed no GD2, GD3 or GM2 gangliosides, cytotoxic T cells with CD4 + CD8 − , CD4 − CD8 + , and CD4 − CD8 − phenotypes reacted with anti‐GD2 monoclonal antibody with various intensities. The reactivity with anti‐GD2 was associated with the intensity of cytotoxic activity as analysed using cytotoxic T lymphocyte (CTL) clones established from the bulk CTLs of each phenotype. An increase of the mRNA expression of GM2/GD2 synthase gene was demonstrated by Northern blot hybridization using RNA extracted from thymocytes, spleen cells, Con A‐treated spleen cells and various types of CTL cells. These results indicated that GD2 ganglioside expression might be associated with the functional differentiation of murine T lymphocytes.
