Abstract |
Adoptively transferred immune spleen cells induce fatal neurological disease in cyclophosphamide-suppressed recipients injected intracerebrally (ic) with a large, but not small, dose of neurotropic lymphocytic choriomeningitis (LCM) virus. The elimination of virus from brain in the latter group, which survives without developing symptoms, depends upon the presence of Lyt 2+ lymphocytes. However removal of Lyt 2+ subset which is cytotoxic in vitro does not diminish the severity of the inflammatory process in vivo, though the onset of clinical disease is delayed in mice given Lyt 2-depleted populations and a larger ic dose of virus. The present findings are consistent with the idea that fatal LCM results from acute, synchronous damage to key functional cells in the central nervous system by virus-immune Lyt 2+, lymphocytes. Even so, if the number of virus-infected CNS cells is still relatively small at the time of T cell invasion, neurological symptoms are not recognized and the mice survive.
