UCP2 up-regulation within the course of autoimmune encephalomyelitis correlates with T-lymphocyte activation.

Multiple sclerosis (MS) is an inflammatory demyelinating autoimmune disorder of the central nervous system (CNS) associated with severe neurological disability. Reactive oxygen species (ROS) and mitochondrial dysfunction play a pivotal role in the pathogenesis of this disease. Several members of the mitochondrial uncoupling protein subfamily (UCP2-UCP5) were suggested to regulate ROS by diminishing the mitochondrial membrane potential and constitute therefore a promising pharmacological target for MS.
