    Snippet: The taiep rats exhibit hypomyelination and suffer progressive demyelination resulting in a highly hypomyelinated central nervous system (CNS) as they reach adulthood [1, 2] . This demyelinating process has been associated with nitrosative stress in vivo and in vitro [3, 4] , glial-microglial activation and lymphocyte migration [4] , and an increase in lipoperoxidation, caspase-3 activation, and cell death in vivo [5] . The taiep rat has been cons.....
    Document: The taiep rats exhibit hypomyelination and suffer progressive demyelination resulting in a highly hypomyelinated central nervous system (CNS) as they reach adulthood [1, 2] . This demyelinating process has been associated with nitrosative stress in vivo and in vitro [3, 4] , glial-microglial activation and lymphocyte migration [4] , and an increase in lipoperoxidation, caspase-3 activation, and cell death in vivo [5] . The taiep rat has been considered as a chronic animal model of multiple sclerosis (MS) [6] , which is characterized by a remyelination failure in areas of chronic demyelination with absence of oligodendrocyte progenitor cells (OPCs) and acute inflammation [7] . It has been suggested that astrogliosis in a microenvironment of chronic inflammation forms a barrier that impedes the OPC migration [7] . However, induction of an acute inflammation in areas of chronic demyelination can activate remyelination as proven in the taiep rat [8] . These results suggest that OPCs in the taiep rat are unable to generate myelinating oligodendrocytes due to the lack of the stimulatory factors and/or the presence of inhibitory factors [8] .
