Molecular and biochemical pathologies in human alcohol-related cerebellar white matter degeneration

Human AUD WM degeneration is associated with oligodendrocyte dysfunction, which mechanistically could be mediated by impairments in insulin/IGF signaling through Akt/GSK-3β or Notch pathway activation. Future studies should focus on the non-invasive detection and monitoring of AUD-related oligodendrocyte pathology through the analysis of cell-type-specific exosomes isolated from peripheral blood.
