Title: Effective treatment of experimental autoimmune neuritis with Fc fragment of human immunoglobulin. Author: Lin HH, Wang MX, Spies JM, Pollard JD. Journal: J Neuroimmunol; 2007 May; 186(1-2):133-40. PubMed ID: 17482276. Abstract: IV immunoglobulin (IVIg) and its Fc fragment proved effective in preventing further progression of experimental autoimmune neuritis (EAN) in the rat induced by whole bovine peripheral nerve myelin and shortening disease duration. This effectiveness was associated with significant differences in electrophysiological parameters including less prolongation of somatosensory evoked potential (S wave) latencies, better maintained S wave amplitudes, less reduction of distal motor nerve conduction velocity, and better maintained amplitudes of compound muscle action potentials of dorsal foot muscles after stimulation at ankle and hip. Moreover, treatment with IVIg and Fc fragments resulted in less extensive inflammation and demyelination in nerve roots evidenced by significantly lower histological grades. The current study provides direct evidence for the first time that Fc fraction of IVIg is the effective component in the treatment of rat EAN.[Abstract] [Full Text] [Related] [New Search]
