Summary of "Leptomeningeal B-cell follicles in multiple sclerosis: a role in the pathogenesis and prognostic value."

B-lymphocytes play an important role in the development and maintenance of the inflammatory process in multiple sclerosis. Recently special attention has been paid to cell formations that are found in the meninges in patients with multiple sclerosis - the so-called leptomeningeal follicle-like structures that contain not only B-lymphocytes, but also other immunocompetent cells, creating a special environment for clonal expansion, selection and further proliferation of B-lymphocytes. Magnetic resonance imaging (MRI) of the brain with gadolinium-based contrast agents reveals local subarachnoid space contrasting that corresponds to the accumulation of the contrast agent by large lymphoid follicles. This phenomenon is called leptomeningeal contrast enhancement and according to some literature data, its severity correlates with the rate of progression of the disease and functional disability. The review presents the available literature on leptomeningeal follicle-like B-cell structures, as well as prospects of using leptomeningeal contrast enhancement on MRI as a potential biomarker for predicting disease severity in patients with multiple sclerosis.

Medical and Biotech [MESH] Definitions

A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (From Ann Neurol 1994;36 Suppl:S73-S79; Adams et al., Principles of Neurology, 6th ed, pp903-914)

A transmembrane protein present in the MYELIN SHEATH of the CENTRAL NERVOUS SYSTEM. It is one of the main autoantigens implicated in the pathogenesis of MULTIPLE SCLEROSIS.

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)

The most common clinical variant of MULTIPLE SCLEROSIS, characterized by recurrent acute exacerbations of neurologic dysfunction followed by partial or complete recovery. Common clinical manifestations include loss of visual (see OPTIC NEURITIS), motor, sensory, or bladder function. Acute episodes of demyelination may occur at any site in the central nervous system, and commonly involve the optic nerves, spinal cord, brain stem, and cerebellum. (Adams et al., Principles of Neurology, 6th ed, pp903-914)
