Nature products of traditional Chinese medicine provide new ideas in γδT cell for tumor immunotherapy

Abstract

Due to the unique features of innate immune cells, the role of γδT cells in tumor immunity has gradually attracted more and more attention. Previous studies have found that γδT cells play a dual role in tumor immunology: tumor-promoting and tumor-controlling. The anti-tumor therapy of γδT cell has made remarkable success in clinical application. Especially in recent years, researchers have provided some novel effective ways such as γδT cell exosomes and adoptive chimeric antigen receptor-γδT cell immunotherapy. However, some problems remain to be solved, such as low expansion rate, poor targeting, and tumor microenvironment limiting the effectiveness of γδT immunotherapy. Traditional Chinese medicine is expected to play a positive role in the body immune-enhancing function, promoting the proliferation and activation of γδT cells, and inducing the differentiation of γδT cells. In this review, we summarize the recent research progress and urgent problems of γδT cell in anti-tumor immunotherapy. Moreover, some new strategies of γδT cell for tumor immunotherapy were proposed.
