内容記述タイプ Abstract
内容記述 A murine monoclonal antibody (IgMκ), termed 3D10, was established by fusion of P3X63Ag8.653 mouse myeloma cells with spleen cells from C3H/HeN mouse immunized with gliomarelated O-acetyl GM3 (NeuAc) having 3-O-acetyl ceramide. The antigens recognized by 3D10 were elucidated through enzyme-linked immunosorbent assay (ELISA) and immunostaining on thin-layer chromatography (TLC-immunostaining). 3D10 reacts with 3-O-acetyl GM3 (NeuAc) in a strong manner than non-acetylated GM3 (NeuAc), but not with 3-O-acetyl GM3 (NeuGc), GM3 (NeuGc), GM1 (NeuAc), GM2 (NeuAc), GD3 (NeuAc), lactosylceramide or glucosylceramide. Furthermore, the reactivity of 3-O-acetyl GM3 (NeuAc) and non-acetylated GM3 (NeuAc) with the monoclonal antibody M2590, which recognizes terminal NeuAc α2?3Galβ1?4Glc (or GlcNAc) residue as a melanoma antigen, was studied through ELISA, TLC-immunostaining and liposome immune lysis assay (LILA). 3-O-acetyl GM3 (NeuAc) showed a lower reactivity than GM3 in these three kinds of assay systems, and this was contrastingly different from the reactivity of 3D10 when tested with the same assay systems. Interestingly, a mixture of 3-O-acetyl GM3 (NeuAc) and non- acetylated GM3 (NeuAc) showed the almost same threshold as GM3 and the nearly same maximum reactivity as 3-O-acetyl GM3 (NeuAc) in LILA. Antibody response after immunization with the 3-O-acetyl GM3 (NeuAc), GM3 (NeuAc), a mixture of GM3 and 3-O-acetyl GM3 (65:35, mol:mol) in the mouse was studied. The liposome containing each ganglioside was injected intraperitoneally and serum antibody response was assayed by ELISA. GM3 induced a low titer anti-GM3 antibody response but an extremely low anti-3-O-?acetyl GM3 titer. 3-O-acetyl GM3 and a mixture of 3-O-acetyl GM3 and GM3 only minimally induced the elevation of serum anti-3-O-acetyl GM3 or anti-GM3 antibody response. These findings suggest that the existence of 3-O-acetyl GM3 could suppress the antibody response in mice.
