  • Tissue injury (chronic disease) associated with persistent LCM infection is apparently caused by the host immune response to the virus. Employing parabiosis or cell transfer from hyperimmune donors to isologous virus carriers, the tissue injury of chronic disease could be initiated and/or intensified. Furthermore, the transfer of anti-LCM antibody to SWR/J carrier mice results in acute necrotizing inflammatory lesions in regions of viral persistence, followed by chronic mononuclear infiltrates quite similar to those seen after the transfer of immune cells. The pathogenesis of the nonglomerular tissue injury of chronic LCM disease is apparently at least in part related to the interaction of circulating anti-LCM antibody with viral antigen at the tissue site. Trapping of circulating virus-antibody complexes in the glomerular filter is apparently the major cause of the glomerulonephritis.
