|Multiple sclerosis (MS) is currently recognized as complex diseases in which inflammatory autoimmune reactivity in the
central nervous system (CNS) results in demyelination, axonal and neuronal pathology. Treatment strategies thus aim
to reduce the detrimental inflammation and induce neuroprotective repair processes. The synthetic copolymer Copaxone
(Glatiramer acetate, GA), an approved drug for the treatment of MS, is the first and so far the only therapeutic agent to have
a copolymer as its active ingredient. Using the animal model of MS, experimental autoimmune encephalomyelitis (EAE), the
mechanism of action of GA was elucidated. These studies indicated that GA treatment generates immunomodulatory shift
from the inflammatory towards the anti-inflammatory pathways, such as Th2-cells that cross the blood brain barrier (BBB)
and secrete in situ anti-inflammatory cytokines as well as T-regulatory cells (Tregs) that suppress the disease. The consequences
of GA treatment on the CNS injury inflicted by the disease were studied using immunohistochemistry, electron microscopy
and magnetic resonance imaging. These analyses revealed reduced demyelination and neuro-axonal damages as well as
neuroprotective repair processes such as neurotrophic factors secretion, remyelination and neurogenesis. These combined
findings indicate that immunomodulatory treatment can counteract the neurodegenerative disease course, supporting linkage
between immunomodulation, neuroprotection and therapeutic activity in the CNS.
