The effect of anti-IL-6 receptor antibodies in suppressing cytotoxic T cell induction was examined. The results showed that CTL activity against alloantigens was statistically significantly reduced in mice treated with anti-IL-6 receptor antibodies as compared to mice not treated with antibodies and mice treated with a control antibody. The anti-IL-6 receptor antibody was also administered to recipients of a mouse model for allogenic heart transplantation. As a result, histopathological findings showed that inflammatory cell infiltration into transplanted hearts was suppressed and the survival period of transplanted hearts was significantly prolonged. Thus, the present inventors for the first time discovered that administration of anti-IL-6 receptor antibodies could suppress cytotoxic T cell induction and thereby suppress acute rejection after transplantation.
