Cellular communication in the tumor microenvironment is crucial for T cell activation; however, the molecular features of the T cell–antigen-presenting cell interaction are still poorly understood. A new study utilizes RNA sequencing of physically interacting cells to reveal that PD-1+CXCL13+ helper T cells in tumors, primed by dendritic cells, are important for the response to immunotherapy.
