Abstract

We used rat myelinated dorsal root ganglion (MDRG) cultures to study antibody and complement-mediated mechanisms of peripheral demyelinating diseases. Heat inactivated serum from a patient (LT) with peripheral neuropathy and a monoclonal IgM reactive with myelin-associated glycoprotein (anti-MAG) and sulfated glucuronosyl glycolipids (anti-SGGL) was used as an antibody source. Incubation of whole human serum (WHS) or WHS and anti-SGGL with MDRGs resulted in reduction of classical and alternative pathway hemolytic activities and the development of abnormal myelin sheaths. Incubation of MDRG cultures with C2-deficient serum showed activation of the alternative complement pathway. Classical pathway hemolytic activity was reduced when Factor B-depleted serum was incubated with MDRG cultures. The rat MDRG culture system provides a good model system of a peripheral nerve and has therefore been used by several investigators to study antibody and complement-mediated demyelination associated with peripheral neuropathies. However, our studies indicate a high degree of complement activation and membrane disruption of cultures incubated with WHS. Copyright (C) 1999 Elsevier Science B.V.
