GM1 is a crucial component of neuronal membrane residing both in the soma and nerve terminals. As reported in Parkinson's disease patients, the reduction of GM1 determines the failure of fundamental functional processes leading to cumulative cell distress up to neuron death. This review reports on the role of GM1 in the pathogenesis of the disease, illustrating the current data available but also hypotheses on the additional mechanisms in which GM1 could be involved and which require further study. In the manuscript we discuss these points trying to explain the role of diminished content of brain GM1, particularly in the nigro-striatal system, in Parkinson's disease etiology and progression.
Keywords: GM1 ganglioside; GM1 oligosaccharide; Neuronale receptors; Parkinson's disease.
