Personal profile

The Glycosphingolipid (GSL) storage diseases are a group of diseases where GSLs accumulate in tissues due to a defect in their lysosomal breakdown. GSL storage diseases have varying degrees of central nervous system involvement and in Tay-Sachs and Sandhoff diseases the neuropathology is very severe and frequently lethal in early infancy.

How lysosomal storage of GSL causes such severe neuropathology is not known at present. A strategy that can be applied to treat these diseases is substrate deprivation.

This approach aims to balance the rate of GSL biosynthesis with the impaired rate of catabolism, thus preventing accumulation of GSLs. Two imino sugar inhibitors of Glucosylceramide synthase, which catalyses the first step in GSL synthesis.

How does the storage of lipids lead to disease?

What are the normal functions of the lipids that accumulate?
