Abstract:
B7-H3,also known as CD276,is a new immune checkpoint discovered in recent years and belongs to the B7 superfamily.It has low or no expression in normal human tissues,but abnormal expres-sion in immune cells and tumor tissues.B7-H3 is related to tumor immunotherapy and plays a dual role of co-stimulation/co-inhibition in tumor microenvironment(TME).Therefore,targeting B7-H3 can achieve accurate tumor immunotherapy,thus enhancing anti-tumor immune responses.As the immune function of B7-H3 in tumors has been widely revealed,targeted drugs have also been developed and have entered preclinical and clinical trials.However,the different forms and functions of B7-H3 in human body are still controversial,the human origin structure has not been analyzed,and its potential receptor has not been confirmed.In this paper,the structure and function of B7-H3,its physiological role in tumor immu-nity and the research progress of targeted therapy are reviewed.In the future,it is necessary to further explore the exact evidence of B7-H3 in tumor immunotherapy and the challenges and limitations of exist-ing therapies,in order to provide new directions and approaches for drug development targeting B7-H3.
