Approval given to market Tysabri in Europe

The European Commission gave approval on June 29, 2006 for Biogen Idec and Elan Corporation to begin marketing Tysabri® (natalizumab) as a treatment for relapsing remitting multiple sclerosis to delay the progression of disability and reduce the frequency of relapses.

Research News

Summaries of all the latest research findings on MS selected by a team based at the Institute of Neurology, London.
Stem cells for the treatment of neurological disorders

This paper reviews all the recent efforts that have been done to stimulate the formation and prevent the death of neurons and glial cells using endogenous stem cells within the adult central nervous system. Many common neurological disorders, such as Parkinson's disease, stroke and multiple sclerosis are going to benefit from this therapeutic advance.

Childhood multiple sclerosis: A review

This paper reviews the characteristics of MS in childhood. Although children and adults with MS have similar neurological symptoms, laboratory (cerebrospinal fluid) data, and neuroimaging findings, the clinical course, pathogenesis, and treatment of childhood onset MS require further investigation.

Significance of T2 lesions in multiple sclerosis: A 13-year longitudinal study

This article describes a 13-year longitudinal study in 30 patients. The authors show that T2 lesions in relapsing-remitting MS correlate strongly with brain tissue loss and brain tissue integrity 13 years later, and with clinical disease severity, though age significantly impacts the clinical correlation. The results provide direct evidence for the disability threshold hypothesis in MS and support monitoring T2 lesions in relapsing-remitting MS.

Is the frequency of MRI abnormalities in isolated optic neuritis related to the prevalence of multiple sclerosis? A global comparison

This study suggests that isolated optic neuritis is more likely to be associated with MRI abnormalities and to be due to MS in geographical regions where MS is more common.

Automated segmentation of multiple sclerosis lesion subtypes with multichannel MRI

This study illustrates a promising method for automated segmentation of MS lesion subtypes (i.e., enhancing lesions, T1 "black holes", T2 hyperintense lesions).

Functional pathway-defined MRI diffusion measures reveal increased transverse diffusivity of water in multiple sclerosis

In this study Functional MRI and Diffusion Tensor Imaging-based fiber tracking were used to define the interhemispheric white matter pathway connecting bilateral supplementary motor areas in 16 MS patients and 16 control subjects. The Nine-hole Peg Test (a test assessing upper limb function) showed significant correlation with transverse diffusivity indicating that probing functional pathways with MRI measures can lead to a better reflection of disease status.

How to successfully apply animal studies in experimental allergic encephalomyelitis to research on multiple sclerosis

This paper reviews the advantages and pitfalls of Experimental Allergic Encephalomyelitis (EAE), an animal model of MS. The authors conclude that over the past 73 years, the EAE model has proved itself remarkably useful for aiding research on MS.

Brain atrophy after immunoablation and stem cell transplantation in multiple sclerosis

The authors measured brain atrophy in nine patients undergoing immunoablation and autologous hematopoietic stem cell transplantation for multiple sclerosis. Atrophy was 10 times faster than before treatment. These observations suggest that brain atrophy after immunoablation may not be due entirely to the resolution of edema but may be related to chemotoxicity.

Cerebellar cortical atrophy in experimental autoimmune encephalomyelitis

This study demonstrates that myelin-specific autoimmune responses can lead to grey matter atrophy in experimental autoimmune encephalomyelitis (EAE), an animal model of MS. A significant decrease in the mean cerebellar cortex volume in mice with EAE as compared to normal controls was observed. The model described can now be used to investigate neuropathologic mechanisms that lead to the development of grey matter atrophy in this setting.

Peripheral PDE4 inhibition produced by L-826,141 prevents experimental autoimmune encephalomyelitis

This study demonstrates that peripheral phosphodiesterase 4 inhibition, produced by a compound labeled as L-826,141, prevents the progression of autoimmune encephalomyelitis, an animal model of multiple sclerosis after the first onset of clinical signs, and suggests that similar compounds may have clinical efficacy in the treatment of MS.
