Suppression of inflammatory responses during myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis is regulated by AKT3 signaling.

ABSTRACT: AKT3, a member of the serine/threonine kinase AKT family, is involved in a variety of biologic processes. AKT3 is expressed in immune cells and is the major AKT isoform in the CNS representing 30% of the total AKT expressed in spinal cord, and 50% in the brain. Myelin-oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis (EAE) is a mouse model in which lymphocytes and monocytes enter the CNS, resulting in inflammation, demyelination, and axonal injury. We hypothesized that during EAE, deletion of AKT3 would negatively affect the CNS of AKT3(-/-) mice, making them more susceptible to CNS damage. During acute EAE, AKT3(-/-)mice were more severely affected than wild type (WT) mice. Evaluation of spinal cords showed that during acute and chronic disease, AKT3(-/-) spin
