Application

Psychosine has been used as a lipid in lipid-protein overlay binding assay.

Biochem/physiol Actions

Psychosine is a neurotoxic lysosphingolipid and a glycolipid precursor for the synthesis of cerebrosides. It is synthesized from galactosylceramide, phrenosin. Elevated psychosine levels are implicated in Krabbe disease. It mediates demyelination and consequently oligodendrocytes degeneration. Psychosine is also correlated to neurological disease, Globoid cell leukodystrophy (GLD), where in galactosylceramidase (GALC) enzyme deficiency leads to its accumulation.

Sphingolipids act as signaling mediators that regulate a diverse range of cellular events. Although numerous sphingolipid functions have been studied, little is known about the effect of sphingolipids on monocyte differentiation into macrophages. Here, we report that two lysosphingolipids, sphingosylphosphorylcholine

Metachromatic leukodystrophy (MLD) is a rare genetic disease characterised by a dysfunction of the enzyme arylsulphatase A leading to the lysosomal accumulation of cerebroside sulphate (sulphatide) causing subsequent demyelination in patients. The enzyme galactosylceramide (cerebroside) sulphotransferase (CST) catalyses the transfer

Infantile Krabbe disease results in the accumulation of lipid-raft-associated galactosylsphingosine (psychosine), demyelination, neurodegeneration and premature death. Recently, axonopathy has been depicted as a contributing factor in the progression of neurodegeneration in the Twitcher mouse, a bona fide mouse model of

Loss-of-function of the lysosomal enzyme galactosyl-ceramidase causes the accumulation of the lipid raft-associated sphingolipid psychosine, the disruption of postnatal myelination, neurodegeneration and early death in most cases of infantile Krabbe disease.
