Abstract

Activation of T lymphocytes is the initiating factor of the occurrence of acute graft‑versus‑host disease (aGVHD), and cytotoxic T lymphocyte antigen‑4 (CTLA‑4) is the inhibitory receptor for activating T cells. T cell immune response cDNA 7 (TIRC7) is considered an upstream regulator of CTLA‑4; however, little is understood regarding the effects of TIRC7 on the regulation of CTLA‑4 in aGVHD. The purpose of the present study was to evaluate the regulatory effects of TIRC7 on aGVHD, mainly in the pathology. Recipient mice were exposed to a preconditioning dose of 7.5 Gy irradiation on the day of the transplantation and were divided into the following groups: Blank control group, bone marrow transplantation control group, total body irradiation group, mild‑moderate aGVHD group and severe aGVHD group. According to the different administration of CTLA‑4 and TIRC7 monoclonal antibodies, the mild‑moderate and severe aGVHD groups were randomly divided into the hematopoietic stem cell transplantation (HSCT) and HSCT + CTLA‑4/TIRC7 groups. Recipient mice were sacrificed at different time points post‑HSCT for histopathological analysis by hematoxylin and eosin staining. Compared with the control and other experimental groups, the mice in the combined CTLA‑4 and TIRC7 group exhibited ameliorated pathological injury, and lower pathology scores of the liver, lung and intestine. These data revealed that intraperitoneal injection of anti‑TIRC7 and/or anti‑CTLA‑4 monoclonal antibody into mice could effectively alleviate the severity of aGVHD.
