Neuroinflammation of the central and peripheral nervous system: an update.

Inflammatory disorders of the peripheral nervous system (PNS) and central nervous system (CNS) are common, and contribute substantially to physical and emotional disability of affected individuals. Often, the afflicted are young and in their active years. In the past, physicians and scientists often had very little to offer in terms of diagnostic precision and therapeutic effectiveness. During the past two decades, both of these relative shortcomings have clearly improved. Some of the recent developments in clinical neuroimmunology are illustrated in this special edition of Clinical and Experimental Immunology.
