title: [Antibody-dependent harmful effect of non-immune spleen cells in acute experimental tick-borne encephalitis in mice].
abstract: The injection of nonprotective dilutions of immune serum and nonimmune spleen cells into mice infected with tick-borne encephalitis virus induced a sharply pronounced immunopathological effect: the mean survival time of the recipients decreased by 3.6 days in comparison with the control animals. This effect was not linked with the increased replication of the virus in the brain. The antibody-dependent damaging action of spleen cells could be reproduced by using the cells of both syngeneic and allogeneic donors. This phenomenon developed only in those cases when antibodies to the infective agent under study were used. The combination of immune serum to Japanese encephalitis virus and nonimmune spleen cells produced no damaging effect. The hypothesis stating that the antibody-dependent damaging action of nonimmune spleen cells arises from the antibody-dependent cytotoxic action of immunocompetent cells on the infected cells of the central nervous system is discussed.
