| Outline of Final Research Achievements |
When anti-GM1 antibody was allowed to act on cultured cells in which PC12 cells were highly expressed with Trk, the amount and activity of neutral sphingomyelinase (nSMase) protein in the cell membrane fraction decreased and sphingomyelin (SM) in the cell membrane fraction increased. anti-GM1 antibody did not affect the amount of cell membrane gangliosides. These results showed that nSMase activity was significantly reduced in the lipid raft fraction, and it is possible that the target molecules of the disease could be reduced by changing the lipid components on the cell membrane and lipid rafts by various methods such as antibodies and drugs.
