LIPIDOMICS OF HUMAN SKIN FIBROBLASTS IN NEIMANN-PICK DISEASE TYPE C

Neimann-Pick Disease type C is a hereditary lysosomal storage disease due to mutations of the NPC1 or NPC2 genes. The products of these genes encodes for components of a lysosomal machinery that transport different kinds of lipids across the lysosomal membrane. The main abnormalities of NPC1 de ciency phenotype is the accumulation of free cholesterol (FC) and sphingolipids (GL) in brain, liver and other organs cells. Neurodegeneration and hepato-splenomegaly are common ndings. The NPC disease, in his severe onset, leads to a precocious exitus, though the inhibition of glyco-SL synthesis by miglustat has shown some clinical bene t. Recently the physiopathological mechanism has been partly el…
