Ganglioside accumulation GM1-ganglioside accumulation 2019-07-06T19:48:26Z Cellular accumulation of GM1 gangliosides. At the neuropathological level, severe infantile GM1-gangliosidosis patients exhibit distended neurons that contain typical lamellar inclusions referred to as membranous cytoplasmic bodies which are also found in other lipidoses. Although neurons are the primary target for storage, astrocytes may also appear abnormally vacuolated. Neuronal pathology in late onset forms is delayed and tends to be more severe in deeper structures of the brain than in the cortex. Inclusions in the liver are of fibrillar nature and are different from the lamellar bodies in neurons. Abnormal accumulation of GM1-ganglioside and, to a much lesser extent, its asialo-derivative GA1, in the brain is the most prominent biochemical feature.
