Multiple sclerosis is a chronic demyelinating autoimmune disease of the CNS with no known cure. Although 12 immunomodulatory therapies exist, they have only modest effects on disease progression. The field has therefore focused on the development of alternative treatment strategies, such as enhancement of remyelination and CNS repair. Progress has been made on a third, complementary treatment a...

Extracellular vesicles (EVs) are membrane-bound particles secreted by almost all cell types. They are classified depending on their biogenesis and size into exosomes and microvesicles or according to their cell origin. EVs play a role in cell-to-cell communication, including contact-free cell synapsis, carrying active membrane proteins, lipids, and genetic material both inside the particle and ...

Neuromyelitis optica (NMO or Devic's syndrome) is a rare demyelinating disease of the CNS that predominantly affects the spinal cord and optic nerves and shares many clinical and radiological features with multiple sclerosis (MS). The association of NMO with autoimmune thyroiditis has been reported very rarely. Early differentiation between NMO and MS is very important because they have differe...

The central nervous system (CNS) tissues, including the brain, the eye, and the spinal cord, are immune-privileged, secluded from the circulation by a complex of barriers, and equipped with their own myeloid cell population, the resident microglia. Based on the classical perspective of immune-brain interactions and on the contribution of such interactions to the progression of multiple sclerosi...

Multiple sclerosis (MS) is an autoimmune inflammatory demyelinating disease of the CNS that causes disability in young adults as a result of the irreversible accumulation of neurological deficits. Although there are potent disease-modifying agents for its initial relapsing-remitting phase, these therapies show limited efficacy in secondary progressive MS (SPMS). Thus, there is an unmet clinical...

Multiple sclerosis (MS) is an inflammatory demyelinating, presumably autoimmune disease of the central nervous system (CNS). Among the available MS therapies, interferon (IFN)β and the recently introduced statins have been reported to exert their immunomodulatory effects through the induction of SOCS1 and SOCS3 in various inflammatory cell subsets. The SOCS proteins negatively regulate cytokine...

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the CNS. Many findings support the assumption that the immune system plays a key role in the pathogenesis of MS, at least during the relapsing-remitting phase of disease.(1,2) Both arms of the adapted immune response seem to be crucial for the induction and maintenance of the autoimmune response as suggested by the succe...

Experimental autoimmune encephalomyelitis (EAE) is a demyelinating pathology of the central nervous system (CNS) used as a model to study multiple sclerosis immunopathology. EAE has also been extensively employed to evaluate potentially therapeutic schemes. Considering the presence of an immune response directed to heat shock proteins (hsps) in autoimmune diseases and the immunoregulatory poten...

Glial growth factor 2 (GGF2) is a neuronal signal that promotes the proliferation and survival of the oligodendrocyte, the myelinating cell of the central nervous system (CNS). The present study examined whether recombinant human GGF2 (rhGGF2) could effect clinical recovery and repair to damaged myelin in chronic relapsing experimental autoimmune encephalomyelitis (EAE) in the mouse, a major an...
