1 Since GD3S is the key enzyme converting a- to b-series gangliosides, it therefore plays a major role in controlling the levels of major brain gangliosides. Gangliosides ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 1 Homo sapiens

3 The first mechanism directly targets the enzymatic activity of GD3S: Upon binding of Abeta to the ganglioside GM3, the immediate substrate of the GD3S, enzymatic turnover of GM3 by GD3S was strongly reduced. Gangliosides ST8 alpha-N-acetyl-neuraminide alpha-2,8-sialyltransferase 1 Homo sapiens

6 GM3 decreased, whereas the ganglioside GD3, the GD3S product, increased Abeta production, resulting in a regulatory feedback cycle, directly linking ganglioside metabolism with APP processing and Abeta generation.
