摘要
In this issue of JEM, Xiaozheng Xu et al. (2023. J. Exp. Med.https://doi.org/10.1084/jem.20221391) report that the inhibitory protein CTLA4 internalizes in cis the B7 stimulatory molecules previously “gnawed” by T cells from antigen-presenting cells (APCs) and in doing so prevents stimulatory T–T interactions.
