inherited diseases of lipid metabolism

Wednesday 26 May 2004

Alterations in lipid homeostasis are known to severely affect neuronal function and cause neurodegenerative diseases.

Enzymes of the sphingolipid and ganglioside pathways in particular are known to be involved in neurodegenerative disorders.

For example, in Faber disease, ceramide levels are changed and in Niemann-Pick diseases the sphingomyelin (SM) level is drastically increased by a lack of acid sphingomyelinase activity, an SM-degrading enzyme.
