Patent number: 9725514Abstract: The present inventors assessed the effect of anti-IL-6 receptor antibodies in suppressing chronic rejection reaction. They assessed the effect of anti-mouse IL-6 receptor antibody (MR16-1) administration in suppressing the chronic rejection reaction using a mouse model for post-heart-transplantation chronic rejection. The result of histopathological analysis of transplanted hearts extirpated 60 days after transplantation revealed that fibrosis of myocardium and vascular stenotic lesions, which are pathological conditions characteristic of the chronic rejection reaction, were significantly suppressed in the MR16-1-treated group as compared to the control group. Thus, MR16-1 administration was demonstrated to have the effect of suppressing chronic rejection reaction. Specifically, the present inventors discovered for the first time that the rejection reaction in the chronic phase after organ transplantation was suppressed by administering an anti-IL-6 receptor antibody.Type: GrantFiled: January 23, 2008Date of Patent: August 8, 2017Assignees: Shinshu University, Chugai Seiyaku Kabushiki KaishaInventors: Masafumi Takahashi, Atsushi Izawa

Patent number: 8623355Abstract: 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.Type: GrantFiled: November 15, 2006Date of Patent: January 7, 2014Assignees: Chugai Seiyaku Kabushiki Kaisha, National Hospital Organization, Shinshu UniversityInventors: Masaji Okada, Masafumi Takahashi, Atsushi Izawa, Yoshiyuki Ohsugi, Masahiko Mihara
