MK-801 Treatment of Oligodendrocytes as a Cellular Model of Aging

Cardiovascular-related accidents such as stroke are currently ranked as the second leading cause of death worldwide, and the risk of stroke increases dramatically with age. Aging results in structural and functional alterations of the oligodendrocytes which lead to loss of neuronal connectivity, cognitive deficits, and increased susceptibility to ischemic damage. Here, we have carried out proteomic profiling of MO3.13 oligodendrocyte cells following treatment with NMDA channel blocker MK-801 to increase our understanding of the mechanisms involved in brain aging, as well as those which render it more susceptible to ischemic damage. The main objective was to identify potential biomarkers which could be used to track disease or therapeutic effects.
